+ +You will likely be tempted to start by rewrite your own backend using your own custom/high-level facilities...<BR> +Think twice! + +If you are new to Dear ImGui, first try using the existing backends as-is. +You will save lots of time integrating the library. +You can LATER decide to rewrite yourself a custom backend if you really need to. +In most situations, custom backends have less features and more bugs than the standard backends we provide. +If you want portability, you can use multiple backends and choose between them either at compile time +or at runtime. + +**Example A**: your engine is built over Windows + DirectX11 but you have your own high-level rendering +system layered over DirectX11.<BR> +Suggestion: try using imgui_impl_win32.cpp + imgui_impl_dx11.cpp first. +Once it works, if you really need it you can replace the imgui_impl_dx11.cpp code with a +custom renderer using your own rendering functions, and keep using the standard Win32 code etc. + +**Example B**: your engine runs on Windows, Mac, Linux and uses DirectX11, Metal, Vulkan respectively.<BR> +Suggestion: use multiple generic backends! +Once it works, if you really need it you can replace parts of backends with your own abstractions. + +**Example C**: your engine runs on platforms we can't provide public backends for (e.g. PS4/PS5, Switch), +and you have high-level systems everywhere.<BR> +Suggestion: try using a non-portable backend first (e.g. win32 + underlying graphics API) to get +your desktop builds working first. This will get you running faster and get your acquainted with +how Dear ImGui works and is setup. You can then rewrite a custom backend using your own engine API. + +Also: +The [multi-viewports feature](https://github.com/ocornut/imgui/issues/1542) of the 'docking' branch allows +Dear ImGui windows to be seamlessly detached from the main application window. This is achieved using an +extra layer to the Platform and Renderer backends, which allows Dear ImGui to communicate platform-specific +requests such as: "create an additional OS window", "create a render context", "get the OS position of this +window" etc. See 'ImGuiPlatformIO' for details. +Supporting the multi-viewports feature correctly using 100% of your own abstractions is more difficult +than supporting single-viewport. +If you decide to use unmodified imgui_impl_XXXX.cpp files, you can automatically benefit from +improvements and fixes related to viewports and platform windows without extra work on your side. diff --git a/subprojects/imgui-1.81/docs/CHANGELOG.txt b/subprojects/imgui-1.81/docs/CHANGELOG.txt new file mode 100644 index 0000000..24f9f40 --- /dev/null +++ b/subprojects/imgui-1.81/docs/CHANGELOG.txt @@ -0,0 +1,2883 @@ +dear imgui +CHANGELOG + +This document holds the user-facing changelog that we also use in release notes. +We generally fold multiple commits pertaining to the same topic as a single entry. +Changes to backends are also included within the individual .cpp files of each backend. + +RELEASE NOTES: https://github.com/ocornut/imgui/releases +REPORT ISSUES, ASK QUESTIONS: https://github.com/ocornut/imgui/issues +COMMITS HISTORY: https://github.com/ocornut/imgui/commits/master +FAQ https://www.dearimgui.org/faq/ +WIKI https://github.com/ocornut/imgui/wiki + +WHEN TO UPDATE? + +- Keeping your copy of Dear ImGui updated regularly is recommended. +- It is generally safe to sync to the latest commit in master or docking branches + The library is fairly stable and regressions tends to be fixed fast when reported. + +HOW TO UPDATE? + +- Overwrite every file except imconfig.h (if you have modified it). +- You may also locally branch to modify imconfig.h and merge latest into your branch. +- Read the `Breaking Changes` section (in imgui.cpp or here in the Changelog). +- If you have a problem with a missing function/symbols, search for its name in the code, there will likely be a comment about it. +- If you are dropping this repository in your codebase, please leave the demo and text files in there, they will be useful. +- You may diff your previous Changelog with the one you just copied and read that diff. +- You may enable `IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in imconfig.h to forcefully disable legacy names and symbols. + Doing it every once in a while is a good way to make sure you are not using obsolete symbols.

DisplayOffset was applied + after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font. + It was also getting in the way of better font scaling, so let's get rid of it now! + If you used DisplayOffset it was probably in association to rasterizing a font at a specific size, + in which case the corresponding offset may be reported into GlyphOffset. (#1619) + If you scaled this value after calling AddFontDefault(), this is now done automatically. +- ImGuiListClipper: Renamed constructor parameters which created an ambiguous alternative to using + the ImGuiListClipper::Begin() function, with misleading edge cases. Always use ImGuiListClipper::Begin()! + Kept inline redirection function (will obsolete). + (note: imgui_memory_editor <0.40 from imgui_club/ used this old clipper API. Update your copy if needed). +- Style: Renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton. +- Renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete). +- Renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), REVERTED CHANGE FROM 1.77. + For variety of reason this is more self-explanatory and less error-prone. Kept inline redirection function. +- Removed return value from OpenPopupOnItemClick() - returned true on mouse release on item - because it + is inconsistent with other popups API and makes others misleading. It's also and unnecessary: you can + use IsWindowAppearing() after BeginPopup() for a similar result. + +Other Changes: + +- Window: Fixed using non-zero pivot in SetNextWindowPos() when the window is collapsed.

(#3452). +- InputText: Added support for Page Up/Down in InputTextMultiline(). (#3430) [@Xipiryon] +- InputText: Added selection helpers in ImGuiInputTextCallbackData(). +- InputText: Added ImGuiInputTextFlags_CallbackEdit to modify internally owned buffer after an edit. + (note that InputText() already returns true on edit, the callback is useful mainly to manipulate the + underlying buffer while focus is active). +- InputText: Fixed using ImGuiInputTextFlags_Password with InputTextMultiline(). (#3427, #3428) + It is a rather unusual or useless combination of features but no reason it shouldn't work! +- InputText: Fixed minor scrolling glitch when erasing trailing lines in InputTextMultiline(). +- InputText: Fixed cursor being partially covered after using Ctrl+End key. +- InputText: Fixed callback's helper DeleteChars() function when cursor is inside the deleted block.

(#3466) +- CheckboxFlags: Display mixed-value/tristate marker when passed flags that have multiple bits set and + stored value matches neither zero neither the full set. +- BeginMenuBar: Fixed minor bug where CursorPosMax gets pushed to CursorPos prior to calling BeginMenuBar(), + so e.g. calling the function at the end of a window would often add +ItemSpacing.y to scrolling range. +- TreeNode, CollapsingHeader: Made clicking on arrow toggle toggle the open state on the Mouse Down event + rather than the Mouse Down+Up sequence, even if the _OpenOnArrow flag isn't set. This is standard behavior + and amends the change done in 1.76 which only affected cases were _OpenOnArrow flag was set. + (This is also necessary to support full multi/range-select/drag and drop operations.) +- Tab Bar: Added TabItemButton() to submit tab that behave like a button. (#3291) [@Xipiryon] +- Tab Bar: Added ImGuiTabItemFlags_Leading and ImGuiTabItemFlags_Trailing flags to position tabs or button + at either end of the tab bar. Those tabs won't be part of the scrolling region, and when reordering cannot + be moving outside of their section. Most often used with TabItemButton(). (#3291) [@Xipiryon] +- Tab Bar: Added ImGuiTabItemFlags_NoReorder flag to disable reordering a given tab. +- Tab Bar: Keep tab item close button visible while dragging a tab (independent of hovering state). +- Tab Bar: Fixed a small bug where closing a tab that is not selected would leave a tab hole for a frame. +- Tab Bar: Fixed a small bug where scrolling buttons (with ImGuiTabBarFlags_FittingPolicyScroll) would + generate an unnecessary extra draw call. +- Tab Bar: Fixed a small bug where toggling a tab bar from Reorderable to not Reorderable would leave + tabs reordered in the tab list popup.

(bug introduced in 1.77 WIP on 2020/06/16) (#3344, #2880) +- Window: Fixed clicking over an item which hovering has been disabled (e.g inhibited by a popup) + from marking the window as moved. +- Drag, Slider: Added ImGuiSliderFlags parameters. + - For float functions they replace the old trailing 'float power=1.0' parameter. + (See #3361 and the "Breaking Changes" block above for all details). + - Added ImGuiSliderFlags_Logarithmic flag to enable logarithmic editing + (generally more precision around zero), as a replacement to the old 'float power' parameter + which was obsoleted. (#1823, #1316, #642) [@Shironekoben, @AndrewBelt] + - Added ImGuiSliderFlags_ClampOnInput flag to force clamping value when using + CTRL+Click to type in a value manually.

[@Shironekoben] +- DragFloatRange2, DragIntRange2: Fixed an issue allowing to drag out of bounds when both + min and max value are on the same value. (#1441) +- InputText, ImDrawList: Fixed assert triggering when drawing single line of text with more + than ~16 KB characters. (Note that current code is going to show corrupted display if after + clipping, more than 16 KB characters are visible in the same low-level ImDrawList::RenderText() + call. ImGui-level functions such as TextUnformatted() are not affected. This is quite rare + but it will be addressed later). (#3349) +- Selectable: Fixed highlight/hit extent when used with horizontal scrolling (in or outside columns). + Also fixed related text clipping when used in a column after the first one. (#3187, #3386) +- Scrolling: Avoid SetScroll, SetScrollFromPos functions from snapping on the edge of scroll + limits when close-enough by (WindowPadding - ItemPadding), which was a tweak with too many + side-effects. The behavior is still present in SetScrollHere functions as they are more explicitly + aiming at making widgets visible. May later be moved to a flag. +- Tab Bar: Allow calling SetTabItemClosed() after a tab has been submitted (will process next frame). +- InvisibleButton: Made public a small selection of ImGuiButtonFlags (previously in imgui_internal.h) + and allowed to pass them to InvisibleButton(): ImGuiButtonFlags_MouseButtonLeft/Right/Middle. + This is a small but rather important change because lots of multi-button behaviors could previously + only be achieved using lower-level/internal API. Now also available via high-level InvisibleButton() + with is a de-facto versatile building block to creating custom widgets with the public API. +- Fonts: Fixed ImFontConfig::GlyphExtraSpacing and ImFontConfig::PixelSnapH settings being pulled + from the merged/target font settings when merging fonts, instead of being pulled from the source + font settings. +- ImDrawList: Thick anti-aliased strokes (> 1.0f) with integer thickness now use a texture-based + path, reducing the amount of vertices/indices and CPU/GPU usage. (#3245) [@Shironekoben] + - This change will facilitate the wider use of thick borders in future style changes. + - Requires an extra bit of texture space (~64x64 by default), relies on GPU bilinear filtering. + - Set `io.AntiAliasedLinesUseTex = false` to disable rendering using this method. + - Clear `ImFontAtlasFlags_NoBakedLines` in ImFontAtlas::Flags to disable baking data in texture. +- ImDrawList: changed AddCircle(), AddCircleFilled() default num_segments from 12 to 0, effectively + enabling auto-tessellation by default. Tweak tessellation in Style Editor->Rendering section, or + by modifying the 'style.CircleSegmentMaxError' value. [@ShironekoBen] +- ImDrawList: Fixed minor bug introduced in 1.75 where AddCircle() with 12 segments would generate + an extra vertex.

Kept inline redirection function (will obsolete). + [NOTE: THIS WAS REVERTED IN 1.79] +- Removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor + of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems. + Kept inline redirection function (will obsolete). +- Removed obsoleted CalcItemRectClosestPoint() entry point (has been asserting since December 2017). + +Other Changes: + +- TreeNode: Fixed bug where BeginDragDropSource() failed when the _OpenOnDoubleClick flag is + enabled (bug introduced in 1.76, but pre-1.76 it would also fail unless the _OpenOnArrow + flag was also set, and _OpenOnArrow is frequently set along with _OpenOnDoubleClick). +- TreeNode: Fixed bug where dragging a payload over a TreeNode() with either _OpenOnDoubleClick + or _OpenOnArrow would open the node. (#143) +- Windows: Fix unintended feedback loops when resizing windows close to main viewport edges. [@rokups] +- Tabs: Added style.TabMinWidthForUnselectedCloseButton settings: + - Set to 0.0f (default) to always make a close button appear on hover (same as Chrome, VS). + - Set to FLT_MAX to only display a close button when selected (merely hovering is not enough). + - Set to an intermediary value to toggle behavior based on width (same as Firefox). +- Tabs: Added a ImGuiTabItemFlags_NoTooltip flag to disable the tooltip for individual tab item + (vs ImGuiTabBarFlags_NoTooltip for entire tab bar). [@Xipiryon] +- Popups: All functions capable of opening popups (OpenPopup*, BeginPopupContext*) now take a new + ImGuiPopupFlags sets of flags instead of a mouse button index. The API is automatically backward + compatible as ImGuiPopupFlags is guaranteed to hold mouse button index in the lower bits. +- Popups: Added ImGuiPopupFlags_NoOpenOverExistingPopup for OpenPopup*/BeginPopupContext* functions + to first test for the presence of another popup at the same level. +- Popups: Added ImGuiPopupFlags_NoOpenOverItems for BeginPopupContextWindow() - similar to testing + for !IsAnyItemHovered() prior to doing an OpenPopup(). +- Popups: Added ImGuiPopupFlags_AnyPopupId and ImGuiPopupFlags_AnyPopupLevel flags for IsPopupOpen(), + allowing to check if any popup is open at the current level, if a given popup is open at any popup + level, if any popup is open at all. +- Popups: Fix an edge case where programmatically closing a popup while clicking on its empty space + would attempt to focus it and close other popups. (#2880) +- Popups: Fix BeginPopupContextVoid() when clicking over the area made unavailable by a modal. (#1636) +- Popups: Clarified some of the comments and function prototypes. +- Modals: BeginPopupModal() doesn't set the ImGuiWindowFlags_NoSavedSettings flag anymore, and will + not always be auto-centered.

(#915, #3091) + Enforce centering using e.g. SetNextWindowPos(io.DisplaySize * 0.5f, ImGuiCond_Appearing, ImVec2(0.5f,0.5f)). +- Metrics: Added a "Settings" section with some details about persistent ini settings. +- Nav, Menus: Fix vertical wrap-around in menus or popups created with multiple appending calls to + BeginMenu()/EndMenu() or BeginPopup(0/EndPopup().

[@ShironekoBen] +- ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius. +- Limiting Columns()/BeginColumns() api to 64 columns with an assert. While the current code + technically supports it, future code may not so we're putting the restriction ahead. + [Undid that change in 1.76] +- imgui_internal.h: changed ImRect() default constructor initializes all fields to 0.0f instead + of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by + adding points into it without explicit initialization, you may need to fix your initial value. + +Other Changes: + +- Inputs: Added ImGuiMouseButton enum for convenience (e.g. ImGuiMouseButton_Right=1). + We forever guarantee that the existing value will not changes so existing code is free to use 0/1/2. +- Nav: Fixed a bug where the initial CTRL-Tab press while in a child window sometimes selected + the current root window instead of always selecting the previous root window. (#787) +- ColorEdit: Fix label alignment when using ImGuiColorEditFlags_NoInputs. (#2955) [@rokups] +- ColorEdit: In HSV display of a RGB stored value, attempt to locally preserve Saturation + when Value==0.0 (similar to changes done in 1.73 for Hue). Removed Hue editing lock since + those improvements in 1.73 makes them unnecessary. (#2722, #2770). [@rokups] +- ColorEdit: "Copy As" context-menu tool shows hex values with a '#' prefix instead of '0x'. +- ColorEdit: "Copy As" content-menu tool shows hex values both with/without alpha when available. +- InputText: Fix corruption or crash when executing undo after clearing input with ESC, as a + byproduct we are allowing to later undo the revert with a CTRL+Z. (#3008). +- InputText: Fix using a combination of _CallbackResize (e.g. for std::string binding), along with the + _EnterReturnsTrue flag along with the rarely used property of using an InputText without persisting + user-side storage. Previously if you had e.g. a local unsaved std::string and reading result back + from the widget, the user string object wouldn't be resized when Enter key was pressed. (#3009) +- MenuBar: Fix minor clipping issue where occasionally a menu text can overlap the right-most border. +- Window: Fix SetNextWindowBgAlpha(1.0f) failing to override alpha component. (#3007) [@Albog] +- Window: When testing for the presence of the ImGuiWindowFlags_NoBringToFrontOnFocus flag we + test both the focused/clicked window (which could be a child window) and the root window. +- ImDrawList: AddCircle(), AddCircleFilled() API can now auto-tessellate when provided a segment + count of zero. Alter tessellation quality with 'style.CircleSegmentMaxError'. [@ShironekoBen] +- ImDrawList: Add AddNgon(), AddNgonFilled() API with a guarantee on the explicit segment count. + In the current branch they are essentially the same as AddCircle(), AddCircleFilled() but as + we will rework the circle rendering functions to use textures and automatic segment count + selection, those new api can fill a gap. [@ShironekoBen] +- Columns: ImDrawList::Channels* functions now work inside columns. Added extra comments to + suggest using user-owned ImDrawListSplitter instead of ImDrawList functions. [@rokups] +- Misc: Added ImGuiMouseCursor_NotAllowed enum so it can be used by more shared widgets. [@rokups] +- Misc: Added IMGUI_DISABLE compile-time definition to make all headers and sources empty. +- Misc: Disable format checks when using stb_printf, to allow using extra formats. + Made IMGUI_USE_STB_SPRINTF a properly documented imconfig.h flag. (#2954) [@loicmolinari] +- Misc: Added misc/single_file/imgui_single_file.h, We use this to validate compiling all *.cpp + files in a same compilation unit. Actual users of that technique (also called "Unity builds") + can generally provide this themselves, so we don't really recommend you use this. [@rokups] +- CI: Added PVS-Studio static analysis on the continuous-integration server. [@rokups] +- Backends: GLFW, SDL, Win32, OSX, Allegro: Added support for ImGuiMouseCursor_NotAllowed. [@rokups] +- Backends: GLFW: Added support for the missing mouse cursors newly added in GLFW 3.4+. [@rokups] +- Backends: SDL: Wayland: use SDL_GetMouseState (because there is no global mouse state available + on Wayland). (#2800, #2802) [@NeroBurner] +- Backends: GLFW, SDL: report Windows key (io.KeySuper) as always released. Neither GLFW nor SDL can + correctly report the key release in every cases (e.g. when using Win+V) causing problems with some + widgets. The next release of GLFW (3.4+) will have a fix for it. However since it is both difficult + and discouraged to make use of this key for Windows application anyway, we just hide it. (#2976) +- Backends: Win32: Added support for #define IMGUI_IMPL_WIN32_DISABLE_GAMEPAD to disable all + XInput using code, and IMGUI_IMPL_WIN32_DISABLE_LINKING_XINPUT to disable linking with XInput, + the later may be problematic if compiling with recent Windows SDK and you want your app to run + on Windows 7. You can instead try linking with Xinput9_1_0.lib instead. (#2716) +- Backends: Glut: Improved FreeGLUT support for MinGW. (#3004) [@podsvirov] +- Backends: Emscripten: Avoid forcefully setting IMGUI_DISABLE_FILE_FUNCTIONS. (#3005) [@podsvirov] +- Examples: OpenGL: Explicitly adding -DIMGUI_IMPL_OPENGL_LOADER_GL3W to Makefile to match linking + settings (otherwise if another loader such as Glew is accessible, the OpenGL3 backend might + automatically use it). (#2919, #2798) +- Examples: OpenGL: Added support for glbinding OpenGL loader. (#2870) [@rokups] +- Examples: Emscripten: Demonstrating embedding fonts in Makefile and code.

Fixed formula responds to (N>=0). + Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay). + Fixed the code and altered default io.KeyRepeatRate,Delay from 0.250,0.050 to 0.300,0.050 to compensate. + If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you. +- Misc: Renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS. (#1038) +- Misc: Renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS. +- Fonts: ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to + conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert. +- Backends: DX12: Added extra ID3D12DescriptorHeap parameter to ImGui_ImplDX12_Init() function. + The value is unused in master branch but will be used by the multi-viewport feature. (#2851) [@obfuscate] + +Other Changes: + +- InputText, Nav: Fixed Home/End key broken when activating Keyboard Navigation. (#787) +- InputText: Filter out ASCII 127 (DEL) emitted by low-level OSX layer, as we are using the Key value. (#2578) +- Layout: Fixed a couple of subtle bounding box vertical positioning issues relating to the handling of text + baseline alignment. The issue would generally manifest when laying out multiple items on a same line, + with varying heights and text baseline offsets. + Some specific examples, e.g. a button with regular frame padding followed by another item with a + multi-line label and no frame padding, such as: multi-line text, small button, tree node item, etc. + The second item was correctly offset to match text baseline, and would interact/display correctly, + but it wouldn't push the contents area boundary low enough. +- Scrollbar: Fixed an issue where scrollbars wouldn't display on the frame following a frame where + all child window contents would be culled. +- ColorPicker: Fixed SV triangle gradient to block (broken in 1.73). (#2864, #2711). [@lewa-j] +- TreeNode: Fixed combination of ImGuiTreeNodeFlags_SpanFullWidth and ImGuiTreeNodeFlags_OpenOnArrow + incorrectly locating the arrow hit position to the left of the frame. (#2451, #2438, #1897) +- TreeNode: The collapsing arrow accepts click even if modifier keys are being held, facilitating + interactions with custom multi-selections patterns. (#2886, #1896, #1861) +- TreeNode: Added IsItemToggledOpen() to explicitly query if item was just open/closed, facilitating + interactions with custom multi-selections patterns. (#1896, #1861) +- DragScalar, SliderScalar, InputScalar: Added p_ prefix to parameter that are pointers to the data + to clarify how they are used, and more comments redirecting to the demo code. (#2844) +- Error handling: Assert if user mistakenly calls End() instead of EndChild() on a child window. (#1651) +- Misc: Optimized storage of window settings data (reducing allocation count). +- Misc: Windows: Do not use _wfopen() if IMGUI_DISABLE_WIN32_FUNCTIONS is defined. (#2815) +- Misc: Windows: Disabled win32 function by default when building with UWP. (#2892, #2895) +- Misc: Using static_assert() when using C++11, instead of our own construct (avoid zealous Clang warnings). +- Misc: Added IMGUI_DISABLE_FILE_FUNCTIONS/IMGUI_DISABLE_DEFAULT_FILE_FUNCTION to nullify or disable + default implementation of ImFileXXX functions linking with fopen/fclose/fread/fwrite. (#2734) +- Docs: Improved and moved FAQ to docs/FAQ.md so it can be readable on the web. [@ButternCream, @ocornut] +- Docs: Moved misc/fonts/README.txt to docs/FONTS.txt. +- Docs: Added permanent redirect from https://www.dearimgui.org/faq to FAQ page. +- Demo: Added simple item reordering demo in Widgets -> Drag and Drop section. (#2823, #143) [@rokups] +- Metrics: Show wire-frame mesh and approximate surface area when hovering ImDrawCmd. [@ShironekoBen] +- Metrics: Expose basic details of each window key/value state storage. +- Examples: DX12: Using IDXGIDebug1::ReportLiveObjects() when DX12_ENABLE_DEBUG_LAYER is enabled. +- Examples: Emscripten: Removed BINARYEN_TRAP_MODE=clamp from Makefile which was removed in Emscripten 1.39.0 + but required prior to 1.39.0, making life easier for absolutely no-one. (#2877, #2878) [@podsvirov] +- Backends: OpenGL2: Explicitly backup, setup and restore GL_TEXTURE_ENV to increase compatibility with + legacy OpenGL applications.

(#787) +- ColorEdit: Disable Hue edit when Saturation==0 instead of letting Hue values jump around. +- ColorEdit, ColorPicker: In HSV display of a RGB stored value, attempt to locally preserve Hue + when Saturation==0, which reduces accidentally lossy interactions. (#2722, #2770) [@rokups] +- ColorPicker: Made rendering aware of global style alpha of the picker can be faded out. (#2711) + Note that some elements won't accurately fade down with the same intensity, and the color wheel + when enabled will have small overlap glitches with (style.Alpha < 1.0). +- TabBar: Fixed single-tab not shrinking their width down. +- TabBar: Fixed clicking on a tab larger than tab-bar width creating a bouncing feedback loop. +- TabBar: Feed desired width (sum of unclipped tabs width) into layout system to allow for auto-resize. (#2768) + (before 1.71 tab bars fed the sum of current width which created feedback loops in certain situations). +- TabBar: Improved shrinking for large number of tabs to avoid leaving extraneous space on the right side. + Individuals tabs are given integer-rounded width and remainder is spread between tabs left-to-right. +- Columns, Separator: Fixed a bug where non-visible separators within columns would alter the next row position + differently than visible ones. +- SliderScalar: Improved assert when using U32 or U64 types with a large v_max value. (#2765) [@loicmouton] +- DragInt, DragFloat, DragScalar: Using (v_min > v_max) allows locking any edits to the value. +- DragScalar: Fixed dragging of unsigned values on ARM cpu (float to uint cast is undefined). (#2780) [@dBagrat] +- TreeNode: Added ImGuiTreeNodeFlags_SpanAvailWidth flag.

In the future we will + aim toward refactoring the hit-system to be front-to-back, allowing more natural overlapping of items, + and then we will be able to make this the default.) +- TreeNode: Added ImGuiTreeNodeFlags_SpanFullWidth flag. This extends the hit-box to both the left-most and + right-most edge of the working area, bypassing indentation. +- CollapsingHeader: Added support for ImGuiTreeNodeFlags_Bullet and ImGuiTreeNodeFlags_Leaf on framed nodes, + mostly for consistency. (#2159, #2160) [@goran-w] +- Selectable: Added ImGuiSelectableFlags_AllowItemOverlap flag in public api (was previously internal only). +- Style: Allow style.WindowMenuButtonPosition to be set to ImGuiDir_None to hide the collapse button. (#2634, #2639) +- Font: Better ellipsis ("...") drawing implementation. Instead of drawing three pixel-ey dots (which was glaringly + unfitting with many types of fonts) we first attempt to find a standard ellipsis glyphs within the loaded set. + Otherwise we render ellipsis using '.' from the font from where we trim excessive spacing to make it as narrow + as possible. (#2775) [@rokups] +- ImDrawList: Clarified the name of many parameters so reading the code is a little easier. (#2740) +- ImDrawListSplitter: Fixed merging channels if the last submitted draw command used a different texture. (#2506) +- Using offsetof() when available in C++11. Avoids Clang sanitizer complaining about old-style macros. (#94) +- ImVector: Added find(), find_erase(), find_erase_unsorted() helpers. +- Added a mechanism to compact/free the larger allocations of unused windows (buffers are compacted when + a window is unused for 60 seconds, as per io.ConfigWindowsMemoryCompactTimer = 60.0f). Note that memory + usage has never been reported as a problem, so this is merely a touch of overzealous luxury. (#2636) +- Documentation: Various tweaks and improvements to the README page. [@ker0chan] +- Backends: OpenGL3: Tweaked initialization code allow application calling ImGui_ImplOpenGL3_CreateFontsTexture() + before ImGui_ImplOpenGL3_NewFrame(), which sometimes can be convenient. +- Backends: OpenGL3: Attempt to automatically detect default GL loader by using __has_include. (#2798) [@o-micron] +- Backends: DX11: Fixed GSGetShader() call not passing an initialized instance count, which would + generally make the DX11 debug layer complain (bug added in 1.72). +- Backends: Vulkan: Added support for specifying multisample count.

Kept redirection typedef (will obsolete). +- Removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). + Kept redirection function (will obsolete). (#581, #324) + +Other Changes: + +- Scrolling: Made mouse-wheel scrolling lock the underlying window until the mouse is moved again or + until a short delay expires (~2 seconds). This allow uninterrupted scroll even if child windows are + passing under the mouse cursor. (#2604) +- Scrolling: Made it possible for mouse wheel and navigation-triggered scrolling to override a call to + SetScrollX()/SetScrollY(), making it possible to use a simpler stateless pattern for auto-scrolling: + // (Submit items..) + if (ImGui::GetScrollY() >= ImGui::GetScrollMaxY()) // If scrolling at the already at the bottom.. + ImGui::SetScrollHereY(1.0f); // ..make last item fully visible +- Scrolling: Added SetScrollHereX(), SetScrollFromPosX() for completeness. (#1580) [@kevreco] +- Scrolling: Mouse wheel scrolling while hovering a child window is automatically forwarded to parent window + if ScrollMax is zero on the scrolling axis. + Also still the case if ImGuiWindowFlags_NoScrollWithMouse is set (not new), but previously the forwarding + would be disabled if ImGuiWindowFlags_NoScrollbar was set on the child window, which is not the case + any more. Forwarding can still be disabled by setting ImGuiWindowFlags_NoInputs. (amend #1502, #1380). +- Window: Fixed InnerClipRect right-most coordinates using wrong padding setting (introduced in 1.71). +- Window: Fixed old SetWindowFontScale() api value from not being inherited by child window. Added + comments about the right way to scale your UI (load a font at the right side, rebuild atlas, scale style). +- Scrollbar: Avoid overlapping the opposite side when window (often a child window) is forcibly too small. +- Combo: Hide arrow when there's not enough space even for the square button. +- InputText: Testing for newly added ImGuiKey_KeyPadEnter key. (#2677, #2005) [@amc522] +- TabBar: Fixed unfocused tab bar separator color (was using ImGuiCol_Tab, should use ImGuiCol_TabUnfocusedActive). +- Columns: Fixed a regression from 1.71 where the right-side of the contents rectangle within each column + would wrongly use a WindowPadding.x instead of ItemSpacing.x like it always did. (#125, #2666) +- Columns: Made the right-most edge reaches up to the clipping rectangle (removing half of WindowPadding.x + worth of asymmetrical/extraneous padding, note that there's another half that conservatively has to offset + the right-most column, otherwise it's clipping width won't match the other columns). (#125, #2666) +- Columns: Improved honoring alignment with various values of ItemSpacing.x and WindowPadding.x. (#125, #2666) +- Columns: Made GetColumnOffset() and GetColumnWidth() behave when there's no column set, consistently with + other column functions. (#2683) +- InputTextMultiline: Fixed vertical scrolling tracking glitch. +- Word-wrapping: Fixed overzealous word-wrapping when glyph edge lands exactly on the limit. Because + of this, auto-fitting exactly unwrapped text would make it wrap. (fixes initial 1.15 commit, 78645a7d). +- Style: Attenuated default opacity of ImGuiCol_Separator in Classic and Light styles. +- Style: Added style.ColorButtonPosition (left/right, defaults to ImGuiDir_Right) to move the color button + of ColorEdit3/ColorEdit4 functions to either side of the inputs. +- IO: Added ImGuiKey_KeyPadEnter and support in various backends (previously backends would need to + specifically redirect key-pad keys to their regular counterpart). This is a temporary attenuating measure + until we actually refactor and add whole sets of keys into the ImGuiKey enum. (#2677, #2005) [@amc522] +- Misc: Made Button(), ColorButton() not trigger an "edited" event leading to IsItemDeactivatedAfterEdit() + returning true. This also effectively make ColorEdit4() not incorrect trigger IsItemDeactivatedAfterEdit() + when clicking the color button to open the picker popup. (#1875) +- Misc: Added IMGUI_DISABLE_METRICS_WINDOW imconfig.h setting to explicitly compile out ShowMetricsWindow(). +- Debug, Metrics: Added "Tools->Item Picker" tool which allow clicking on a widget to break in the debugger + within the item code. The tool calls IM_DEBUG_BREAK() which can be redefined in imconfig.h if needed. +- ImDrawList: Fixed CloneOutput() helper crashing. (#1860) [@gviot] +- ImDrawList::ChannelsSplit(), ImDrawListSplitter: Fixed an issue with merging draw commands between + channel 0 and 1. (#2624) +- ImDrawListSplitter: Fixed memory leak when using low-level split api (was not affecting ImDrawList api, + also this type was added in 1.71 and not advertised as a public-facing feature). +- Fonts: binary_to_compressed_c.cpp: Display an error message if failing to open/read the input font file. +- Demo: Log, Console: Using a simpler stateless pattern for auto-scrolling. +- Demo: Widgets: Showing how to use the format parameter of Slider/Drag functions to display the name + of an enum value instead of the underlying integer value. +- Demo: Renamed the "Help" menu to "Tools" (more accurate). +- Backends: DX10/DX11: Backup, clear and restore Geometry Shader is any is bound when calling renderer. +- Backends: DX11: Clear Hull Shader, Domain Shader, Compute Shader before rendering. Not backing/restoring them. +- Backends: OSX: Disabled default native Mac clipboard copy/paste implementation in core library (added in 1.71), + because it needs application to be linked with '-framework ApplicationServices'. It can be explicitly + enabled back by using '#define IMGUI_ENABLE_OSX_DEFAULT_CLIPBOARD_FUNCTIONS' in imconfig.h.

Kept inline redirection function (will obsolete). +- Window: rendering of child windows outer decorations (e.g. bg color, border, scrollbars) is now + performed as part of their parent window, avoiding the creation of an extraneous draw commands. + If you have overlapping child windows with decorations, and relied on their relative z-order to be + mapped to submission their order, this will affect your rendering. The optimization is disabled + if the parent window has no visual output because it appears to be the most common situation leading + to the creation of overlapping child windows. Please reach out if you are affected by this change! + +Other Changes: + +- Window: clarified behavior of SetNextWindowContentSize(). Content size is defined as the size available + after removal of WindowPadding on each sides. So SetNextWindowContentSize(ImVec2(100,100)) + auto-resize + will always allow submitting a 100x100 item without creating a scrollbar, regarding of WindowPadding. + The exact meaning of ContentSize for decorated windows was previously ill-defined. +- Window: Fixed auto-resize with AlwaysVerticalScrollbar or AlwaysHorizontalScrollbar flags. +- Window: Fixed one case where auto-resize by double-clicking the resize grip would make either scrollbar + appear for a single frame after the resize. +- Separator: Revert 1.70 "Declare its thickness (1.0f) to the layout" change. It's not incorrect + but it breaks existing some layout patterns. Will return back to it when we expose Separator flags. +- Fixed InputScalar, InputScalarN, SliderScalarN, DragScalarN with non-visible label from inserting + style.ItemInnerSpacing.x worth of trailing spacing. +- Fixed InputFloatX, SliderFloatX, DragFloatX functions erroneously reporting IsItemEdited() multiple + times when the text input doesn't match the formatted output value (e.g. input "1" shows "1.000"). + It wasn't much of a problem because we typically use the return value instead of IsItemEdited() here. +- Fixed uses of IsItemDeactivated(), IsItemDeactivatedAfterEdit() on multi-components widgets and + after EndGroup(). (#2550, #1875) +- Fixed crash when appending with BeginMainMenuBar() more than once and no other window are showing. (#2567) +- ColorEdit: Fixed the color picker popup only displaying inputs as HSV instead of showing multiple + options. (#2587, broken in 1.69 by #2384). +- CollapsingHeader: Better clipping when a close button is enabled and it overlaps the label. (#600) +- Scrollbar: Minor bounding box adjustment to cope with various border size. +- Scrollbar, Style: Changed default style.ScrollbarSize from 16 to 14. +- Combo: Fixed rounding not applying with the ImGuiComboFlags_NoArrowButton flag. (#2607) [@DucaRii] +- Nav: Fixed gamepad/keyboard moving of window affecting contents size incorrectly, sometimes leading + to scrollbars appearing during the movement. +- Nav: Fixed rare crash when e.g. releasing Alt-key while focusing a window with a menu at the same + frame as clearing the focus. This was in most noticeable in backends such as Glfw and SDL which + emits key release events when focusing another viewport, leading to Alt+clicking on void on another + viewport triggering the issue. (#2609) +- TreeNode, CollapsingHeader: Fixed highlight frame not covering horizontal area fully when using + horizontal scrolling. (#2211, #2579) +- TabBar: Fixed BeginTabBar() within a window with horizontal scrolling from creating a feedback + loop with the horizontal contents size. +- Columns: Fixed Columns() within a window with horizontal scrolling from not covering the full + horizontal area (previously only worked with an explicit contents size). (#125) +- Columns: Fixed Separator from creating an extraneous draw command. (#125) +- Columns: Fixed Selectable with SpanAllColumns flag from creating an extraneous draw command. (#125) +- Style: Added style.WindowMenuButtonPosition (left/right, defaults to ImGuiDir_Left) to move the + collapsing/docking button to the other side of the title bar. +- Style: Made window close button cross slightly smaller. +- Log/Capture: Fixed BeginTabItem() label not being included in a text log/capture. +- ImDrawList: Added ImDrawCmd::VtxOffset value to support large meshes (64k+ vertices) using 16-bit indices. + The renderer backend needs to set 'io.BackendFlags |= ImGuiBackendFlags_RendererHasVtxOffset' to enable + this, and honor the ImDrawCmd::VtxOffset field. Otherwise the value will always be zero. (#2591) + This has the advantage of preserving smaller index buffers and allowing to execute on hardware that do not + support 32-bit indices. Most examples backends have been modified to support the VtxOffset field. +- ImDrawList: Added ImDrawCmd::IdxOffset value, equivalent to summing element count for each draw command. + This is provided for convenience and consistency with VtxOffset. (#2591) +- ImDrawCallback: Allow to override the signature of ImDrawCallback by #define-ing it. This is meant to + facilitate custom rendering backends passing local render-specific data to the draw callback. +- ImFontAtlas: FreeType: Added RasterizerFlags::Monochrome flag to disable font anti-aliasing. Combine + with RasterizerFlags::MonoHinting for best results. (#2545) [@HolyBlackCat] +- ImFontGlyphRangesBuilder: Fixed unnecessarily over-sized buffer, which incidentally was also not + fully cleared. Fixed edge-case overflow when adding character 0xFFFF. (#2568). [@NIKE3500] +- Demo: Added full "Dear ImGui" prefix to the title of "Dear ImGui Demo" and "Dear ImGui Metrics" windows. +- Backends: Add native Mac clipboard copy/paste default implementation in core library to match what we are + dealing with Win32, and to facilitate integration in custom engines. (#2546) [@andrewwillmott] +- Backends: OSX: imgui_impl_osx: Added mouse cursor support. (#2585, #1873) [@actboy168] +- Examples/Backends: DirectX9/10/11/12, Metal, Vulkan, OpenGL3 (Desktop GL only): Added support for large meshes + (64k+ vertices) with 16-bit indices, enable 'ImGuiBackendFlags_RendererHasVtxOffset' in those backends. (#2591) +- Examples/Backends: Don't filter characters under 0x10000 before calling io.AddInputCharacter(), + the filtering is done in io.AddInputCharacter() itself.

If you have custom rendering using thick lines, + they will appear a little thicker now. (#2518) [@rmitton] +- Obsoleted GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. + Kept inline redirection function. +- Examples: Vulkan: Added MinImageCount/ImageCount fields in ImGui_ImplVulkan_InitInfo, required + during initialization to specify the number of in-flight image requested by swap chains. + (was previously a hard #define IMGUI_VK_QUEUED_FRAMES 2). (#2071, #1677) [@nathanvoglsam] +- Examples: Vulkan: Tidying up the demo/internals helpers (most engine/app should not rely + on them but it is possible you have!). + +Other Changes: + +- ImDrawList: Added ImDrawCallback_ResetRenderState, a special ImDrawList::AddCallback() value + to request the renderer backend to reset its render state. (#2037, #1639, #2452) + Examples: Added support for ImDrawCallback_ResetRenderState in all renderer backends. Each + renderer code setting up initial render state has been moved to a function so it could be + called at the start of rendering and when a ResetRenderState is requested. [@ocornut, @bear24rw] +- InputText: Fixed selection background rendering one frame after the cursor movement when + first transitioning from no-selection to has-selection. (Bug in 1.69) (#2436) [@Nazg-Gul] +- InputText: Work-around for buggy standard libraries where isprint('\t') returns true. (#2467, #1336) +- InputText: Fixed ImGuiInputTextFlags_AllowTabInput leading to two tabs characters being inserted + if the backend provided both Key and Character input. (#2467, #1336) +- Layout: Added SetNextItemWidth() helper to avoid using PushItemWidth/PopItemWidth() for single items. + Note that SetNextItemWidth() currently only affect the same subset of items as PushItemWidth(), + generally referred to as the large framed+labeled items. Because the new SetNextItemWidth() + function is explicit we may later extend its effect to more items. +- Layout: Fixed PushItemWidth(-width) for right-side alignment laying out some items (button, listbox, etc.) + with negative sizes if the 'width' argument was smaller than the available width at the time of item + submission. +- Window: Fixed window with the AlwaysAutoResize flag unnecessarily extending their hovering boundaries + by a few pixels (this is used to facilitate resizing from borders when available for a given window). + One of the noticeable minor side effect was that navigating menus would have had a tendency to disable + highlight from parent menu items earlier than necessary while approaching the child menu. +- Window: Close button is horizontally aligned with style.FramePadding.x. +- Window: Fixed contents region being off by WindowBorderSize amount on the right when scrollbar is active. +- Window: Fixed SetNextWindowSizeConstraints() with non-rounded positions making windows drift. (#2067, #2530) +- Popups: Closing a popup restores the focused/nav window in place at the time of the popup opening, + instead of restoring the window that was in the window stack at the time of the OpenPopup call. (#2517) + Among other things, this allows opening a popup while no window are focused, and pressing Escape to + clear the focus again. +- Popups: Fixed right-click from closing all popups instead of aiming at the hovered popup level + (regression in 1.67). +- Selectable: With ImGuiSelectableFlags_AllowDoubleClick doesn't return true on the mouse button release + following the double-click. Only first mouse release + second mouse down (double-click) returns true. + Likewise for internal ButtonBehavior() with both _PressedOnClickRelease | _PressedOnDoubleClick. (#2503) +- GetMouseDragDelta(): also returns the delta on the mouse button released frame.

(#2424, #1463) [@LucaRood] +- PlotLines, PlotHistogram: Ignore NaN values when calculating min/max bounds. (#2485) +- Columns: Fixed boundary of clipping being off by 1 pixel within the left column. (#125) +- Separator: Declare its thickness (1.0f) to the layout, making items around separator more symmetrical. +- Combo, Slider, Scrollbar: Improve rendering in situation when there's only a few pixels available (<3 pixels). +- Nav: Fixed Drag/Slider functions going into text input mode when keyboard CTRL is held while pressing NavActivate. +- Drag and Drop: Fixed drag source with ImGuiDragDropFlags_SourceAllowNullID and null ID from receiving click + regardless of being covered by another window (it didn't honor correct hovering rules). (#2521) +- ImDrawList: Improved algorithm for mitre joints on thick lines, preserving correct thickness up to 90 degrees + angles, also faster to output. (#2518) [@rmitton] +- Misc: Added IM_MALLOC/IM_FREE macros mimicking IM_NEW/IM_DELETE so user doesn't need to revert + to using the ImGui::MemAlloc()/MemFree() calls directly. +- Misc: Made IMGUI_CHECKVERSION() macro also check for matching size of ImDrawIdx. +- Metrics: Added "Show windows rectangles" tool to visualize the different rectangles. +- Demo: Improved trees in columns demo. +- Examples: OpenGL: Added a test GL call + comments in ImGui_ImplOpenGL3_Init() to detect uninitialized + GL function loaders early, and help users understand what they are missing. (#2421) +- Examples: SDL: Added support for SDL_GameController gamepads (enable with ImGuiConfigFlags_NavEnableGamepad). (#2509) [@DJLink] +- Examples: Emscripten: Added Emscripten+SDL+GLES2 example.

(#2527) [@bear24rw] +- Examples: OpenGL3: Minor tweaks + not calling glBindBuffer more than necessary in the render loop. +- Examples: Vulkan: Fixed in-flight buffers issues when using multi-viewports. (#2461, #2348, #2378, #2097) +- Examples: Vulkan: Added missing support for 32-bit indices (#define ImDrawIdx unsigned int). +- Examples: Vulkan: Avoid passing negative coordinates to vkCmdSetScissor, which debug validation layers do not like. +- Examples: Vulkan: Added ImGui_ImplVulkan_SetMinImageCount() to change min image count at runtime. (#2071) [@nathanvoglsam] +- Examples: DirectX9: Fixed erroneous assert in ImGui_ImplDX9_InvalidateDeviceObjects(). (#2454) +- Examples: DirectX10/11/12, Allegro, Marmalade: Render functions early out when display size is zero (minimized). (#2496) +- Examples: GLUT: Fixed existing FreeGLUT example to work with regular GLUT. (#2465) [@andrewwillmott] +- Examples: GLUT: Renamed imgui_impl_freeglut.cpp/.h to imgui_impl_glut.cpp/.h. (#2465) [@andrewwillmott] +- Examples: GLUT: Made io.DeltaTime always > 0. (#2430) +- Examples: Visual Studio: Updated default platform toolset+sdk in vcproj files from v100+sdk7 (vs2010) + to v110+sdk8 (vs2012). This is mostly so we can remove reliance on DXSDK_DIR for the DX10/DX11 example, + which if existing and when switching to recent SDK ends up conflicting and creating warnings. + + +----------------------------------------------------------------------- + VERSION 1.69 (Released 2019-03-13) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.69 + +Breaking Changes: + +- Renamed ColorEdit/ColorPicker's ImGuiColorEditFlags_RGB/_HSV/_HEX flags to respectively + ImGuiColorEditFlags_DisplayRGB/_DisplayHSV/_DisplayHex. This is because the addition of + new flag ImGuiColorEditFlags_InputHSV makes the earlier one ambiguous. + Kept redirection enum values (will obsolete). (#2384) [@haldean] +- Renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete). (#2391) + +Other Changes: + +- Added GetBackgroundDrawList() helper to quickly get access to a ImDrawList that will be rendered + behind every other windows. (#2391, #545) +- DragScalar, InputScalar, SliderScalar: Added support for u8/s8/u16/s16 data types (ImGuiDataType_S8, etc.) + We are reusing function instances of larger types to reduce code size. (#643, #320, #708, #1011) +- Added InputTextWithHint() to display a description/hint in the text box when no text + has been entered. (#2400) [@Organic-Code, @ocornut] +- Nav: Fixed a tap on AltGR (e.g. German keyboard) from navigating to the menu layer. +- Nav: Fixed Ctrl+Tab keeping active InputText() of a previous window active after the switch. (#2380) +- Fixed IsItemDeactivated()/IsItemDeactivatedAfterEdit() from not correctly returning true + when tabbing out of a focusable widget (Input/Slider/Drag) in most situations. (#2215, #1875) +- InputInt, InputFloat, InputScalar: Fix to keep the label of the +/- buttons centered when + style.FramePadding.x is abnormally larger than style.FramePadding.y. Since the buttons are + meant to be square (to align with e.g. color button) we always use FramePadding.y. (#2367) +- InputInt, InputScalar: +/- buttons now respects the natural type limits instead of + overflowing or underflowing the value. +- InputText: Fixed an edge case crash that would happen if another widget sharing the same ID + is being swapped with an InputText that has yet to be activated. +- InputText: Fixed various display corruption related to swapping the underlying buffer while + a input widget is active (both for writable and read-only paths). Often they would manifest + when manipulating the scrollbar of a multi-line input text. +- ColorEdit, ColorPicker, ColorButton: Added ImGuiColorEditFlags_InputHSV to manipulate color + values encoded as HSV (in order to avoid HSV<>RGB round trips and associated singularities). + (#2383, #2384) [@haldean] +- ColorPicker: Fixed a bug/assertion when displaying a color picker in a collapsed window + while dragging its title bar. (#2389) +- ColorEdit: Fixed tooltip not honoring the ImGuiColorEditFlags_NoAlpha contract of never + reading the 4th float in the array (value was read and discarded). (#2384) [@haldean] +- MenuItem, Selectable: Fixed disabled widget interfering with navigation (fix c2db7f63 in 1.67). +- TabBar: Fixed a crash when using many BeginTabBar() recursively (didn't affect docking). (#2371) +- TabBar: Added extra mis-usage error recovery. Past the assert, common mis-usage don't lead to + hard crashes any more, facilitating integration with scripting languages. (#1651) +- TabBar: Fixed ImGuiTabItemFlags_SetSelected being ignored if the tab is not visible (with + scrolling policy enabled) or if is currently appearing. +- TabBar: Fixed Tab tooltip code making drag and drop tooltip disappear during the frame where + the drag payload activate a tab. +- TabBar: Reworked scrolling policy (when ImGuiTabBarFlags_FittingPolicyScroll is set) to + teleport the view when aiming at a tab far away the visible section, and otherwise accelerate + the scrolling speed to cap the scrolling time to 0.3 seconds. +- Text: Fixed large Text/TextUnformatted calls not feeding their size into layout when starting + below the lower point of the current clipping rectangle. This bug has been there since v1.0! + It was hardly noticeable but would affect the scrolling range, which in turn would affect + some scrolling request functions when called during the appearing frame of a window. +- Plot: Fixed divide-by-zero in PlotLines() when passing a count of 1. (#2387) [@Lectem] +- Log/Capture: Fixed LogXXX functions emitting extraneous leading carriage return. +- Log/Capture: Fixed an issue when empty string on a new line would not emit a carriage return. +- Log/Capture: Fixed LogXXX functions 'auto_open_depth' parameter being treated as an absolute + tree depth instead of a relative one. +- Log/Capture: Fixed CollapsingHeader trailing ascii representation being "#" instead of "##". +- ImFont: Added GetGlyphRangesVietnamese() helper. (#2403) +- Misc: Asserting in NewFrame() if style.WindowMinSize is zero or smaller than (1.0f,1.0f). +- Demo: Using GetBackgroundDrawList() and GetForegroundDrawList() in "Custom Rendering" demo. +- Demo: InputText: Demonstrating use of ImGuiInputTextFlags_CallbackResize. (#2006, #1443, #1008). +- Examples: GLFW, SDL: Preserve DisplayFramebufferScale when main viewport is minimized. + (This is particularly useful for the viewport branch because we are not supporting per-viewport + frame-buffer scale. It fixes windows not refreshing when main viewport is minimized.) (#2416) +- Examples: OpenGL: Fix to be able to run on ES 2.0 / WebGL 1.0. [@rmitton, @gabrielcuvillier] +- Examples: OpenGL: Fix for OSX not supporting OpenGL 4.5, we don't try to read GL_CLIP_ORIGIN + even if the OpenGL headers/loader happens to define the value. (#2366, #2186) +- Examples: Allegro: Added support for touch events (emulating mouse). (#2219) [@dos1] +- Examples: DirectX9: Minor changes to match the other DirectX examples more closely.

(#2038) [@kudaba] +- ImDrawData: Added FramebufferScale field (currently a copy of the value from io.DisplayFramebufferScale). + This is to allow render functions being written without pulling any data from ImGuiIO, allowing incoming + multi-viewport feature to behave on Retina display and with multiple displays. + If you are not using a custom backend, please update your render function code ahead of time, + and use draw_data->FramebufferScale instead of io.DisplayFramebufferScale. (#2306, #1676) +- Added IsItemActivated() as an extension to the IsItemDeactivated/IsItemDeactivatedAfterEdit functions + which are useful to implement variety of undo patterns. (#820, #956, #1875) +- InputText: Fixed a bug where ESCAPE would not restore the initial value in all situations. (#2321) [@relick] +- InputText: Fixed a bug where ESCAPE would be first captured by the Keyboard Navigation code. (#2321, #787) +- InputText: Fixed redo buffer exhaustion handling (rare) which could corrupt the undo character buffer. (#2333) + The way the redo/undo buffers work would have made it generally unnoticeable to the user. +- Fixed range-version of PushID() and GetID() not honoring the ### operator to restart from the seed value. +- Fixed CloseCurrentPopup() on a child-menu of a modal incorrectly closing the modal. (#2308) +- Tabs: Added ImGuiTabBarFlags_TabListPopupButton flag to show a popup button on manual tab bars. (#261, #351) +- Tabs: Removed ImGuiTabBarFlags_NoTabListPopupButton which was available in 1.67 but actually had zero use. +- Tabs: Fixed a minor clipping glitch when changing style's FramePadding from frame to frame. +- Tabs: Fixed border (when enabled) so it is aligned correctly mid-pixel and appears as bright as other borders. +- Style, Selectable: Added ImGuiStyle::SelectableTextAlign and ImGuiStyleVar_SelectableTextAlign. (#2347) [@haldean] +- Menus: Tweaked horizontal overlap between parent and child menu (to help convey relative depth) + from using style.ItemSpacing.x to style.ItemInnerSpacing.x, the later being expected to be smaller. (#1086) +- RadioButton: Fixed label horizontal alignment to precisely match Checkbox(). +- Window: When resizing from an edge, the border is more visible and better follow the rounded corners. +- Window: Fixed initial width of collapsed windows not taking account of contents width (broken in 1.67). (#2336, #176) +- Scrollbar: Fade out and disable interaction when too small, in order to facilitate using the resize grab on very + small window, as well as reducing visual noise/overlap. +- ListBox: Better optimized when clipped / non-visible. +- InputTextMultiline: Better optimized when clipped / non-visible. +- Font: Fixed high-level ImGui::CalcTextSize() used by most widgets from erroneously subtracting 1.0f*scale to + calculated text width. Among noticeable side-effects, it would make sequences of repeated Text/SameLine calls + not align the same as a single call, and create mismatch between high-level size calculation and those performed + with the lower-level ImDrawList api. (#792) [@SlNPacifist] +- Font: Fixed building atlas when specifying duplicate/overlapping ranges within a same font. (#2353, #2233) +- ImDrawList: Fixed AddCircle(), AddCircleFilled() angle step being off, which was visible when drawing a "circle" + with a small number of segments (e.g. an hexagon). (#2287) [@baktery] +- ImGuiTextBuffer: Added append() function (unformatted). +- ImFontAtlas: Added 0x2000-0x206F general punctuation range to default ChineseFull/ChineseSimplifiedCommon ranges. (#2093) +- ImFontAtlas: FreeType: Added support for imgui allocators + custom FreeType only SetAllocatorFunctions. (#2285) [@Vuhdo] +- ImFontAtlas: FreeType: Fixed using imgui_freetype.cpp in unity builds. (#2302) +- Demo: Fixed "Log" demo not initializing properly, leading to the first line not showing before a Clear. (#2318) [@bluescan] +- Demo: Added "Auto-scroll" option in Log/Console demos. (#2300) [@nicolasnoble, @ocornut] +- Examples: Metal, OpenGL2, OpenGL3, Vulkan: Fixed offsetting of clipping rectangle with ImDrawData::DisplayPos != (0,0) + when the display frame-buffer scale scale is not (1,1). While this doesn't make a difference when using master branch, + this is effectively fixing support for multi-viewport with Mac Retina Displays on those examples. (#2306) [@rasky, @ocornut] + Also using ImDrawData::FramebufferScale instead of io.DisplayFramebufferScale. +- Examples: Clarified the use the ImDrawData::DisplayPos to offset clipping rectangles. +- Examples: Win32: Using GetForegroundWindow()+IsChild() instead of GetActiveWindow() to be compatible with windows created + in a different thread or parent. (#1951, #2087, #2156, #2232) [many people] +- Examples: SDL: Using the SDL_WINDOW_ALLOW_HIGHDPI flag. (#2306, #1676) [@rasky] +- Examples: Win32: Added support for XInput gamepads (if ImGuiConfigFlags_NavEnableGamepad is enabled). +- Examples: Win32: Added support for mouse buttons 4 and 5 via WM_XBUTTON* messages. (#2264) +- Examples: DirectX9: Explicitly disable fog (D3DRS_FOGENABLE) before drawing in case user state has it set. (#2288, #2230) +- Examples: OpenGL2: Added #define GL_SILENCE_DEPRECATION to cope with newer XCode warnings. +- Examples: OpenGL3: Using GLSL 4.10 shaders for any GLSL version over 410 (e.g. 430, 450). (#2329) [@BrutPitt] + + +----------------------------------------------------------------------- + VERSION 1.67 (Released 2019-01-14) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.67 + +Breaking Changes: + +- Made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable + side-effect because the window would have ID zero. In particular it is causing problems in viewport/docking branches. +- Renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges and removed its [Beta] mark. + The addition of new configuration options in the Docking branch is pushing for a little reorganization of those names. +- Renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete). + +Other Changes: +- Added BETA api for Tab Bar/Tabs widgets: (#261, #351) + - Added BeginTabBar(), EndTabBar(), BeginTabItem(), EndTabItem(), SetTabItemClosed() API. + - Added ImGuiTabBarFlags flags for BeginTabBar(). + - Added ImGuiTabItemFlags flags for BeginTabItem(). + - Style: Added ImGuiCol_Tab, ImGuiCol_TabHovered, ImGuiCol_TabActive, ImGuiCol_TabUnfocused, ImGuiCol_TabUnfocusedActive colors. + - Demo: Added Layout->Tabs demo code. + - Demo: Added "Documents" example app showcasing possible use for tabs. + This feature was merged from the Docking branch in order to allow the use of regular tabs in your code. + (It does not provide the docking/splitting/merging of windows available in the Docking branch) +- Added ImGuiWindowFlags_UnsavedDocument window flag to append '*' to title without altering the ID, as a convenience + to avoid using the ### operator. In the Docking branch this also has an effect on tab closing behavior. +- Window, Focus, Popup: Fixed an issue where closing a popup by clicking another window with the _NoMove flag would refocus + the parent window of the popup instead of the newly clicked window. +- Window: Contents size is preserved while a window collapsed. Fix auto-resizing window losing their size for one frame when uncollapsed. +- Window: Contents size is preserved while a window contents is hidden (unless it is hidden for resizing purpose). +- Window: Resizing windows from edge is now enabled by default (io.ConfigWindowsResizeFromEdges=true). Note that + it only works _if_ the backend sets ImGuiBackendFlags_HasMouseCursors, which the standard backends do. +- Window: Added io.ConfigWindowsMoveFromTitleBarOnly option. This is ignored by window with no title bars (often popups). + This affects clamping window within the visible area: with this option enabled title bars need to be visible. (#899) +- Window: Fixed using SetNextWindowPos() on a child window (which wasn't really documented) position the cursor as expected + in the parent window, so there is no mismatch between the layout in parent and the position of the child window. +- InputFloat: When using ImGuiInputTextFlags_ReadOnly the step buttons are disabled. (#2257) +- DragFloat: Fixed broken mouse direction change with power!=1.0. (#2174, #2206) [@Joshhua5] +- Nav: Fixed an keyboard issue where holding Activate/Space for longer than two frames on a button would unnecessary + keep the focus on the parent window, which could steal it from newly appearing windows. (#787) +- Nav: Fixed animated window titles from being updated when displayed in the CTRL+Tab list. (#787) +- Error recovery: Extraneous/undesired calls to End() are now being caught by an assert in the End() function closer + to the user call site (instead of being reported in EndFrame). Past the assert, they don't lead to crashes any more. (#1651) + Missing calls to End(), past the assert, should not lead to crashes or to the fallback Debug window appearing on screen. + Those changes makes it easier to integrate dear imgui with a scripting language allowing, given asserts are redirected + into e.g. an error log and stopping the script execution. +- ImFontAtlas: Stb and FreeType: Atlas width is now properly based on total surface rather than glyph count (unless overridden with TexDesiredWidth). +- ImFontAtlas: Stb and FreeType: Fixed atlas builder so missing glyphs won't influence the atlas texture width. (#2233) +- ImFontAtlas: Stb and FreeType: Fixed atlas builder so duplicate glyphs (when merging fonts) won't be included in the rasterized atlas. +- ImFontAtlas: FreeType: Fixed abnormally high atlas height. +- ImFontAtlas: FreeType: Fixed support for any values of TexGlyphPadding (not just only 1). +- ImDrawList: Optimized some of the functions for performance of debug builds where non-inline function call cost are non-negligible. + (Our test UI scene on VS2015 Debug Win64 with /RTC1 went ~5.9 ms -> ~4.9 ms. In Release same scene stays at ~0.3 ms.) +- IO: Added BackendPlatformUserData, BackendRendererUserData, BackendLanguageUserData void* for storage use by backends. +- IO: Renamed InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead! +- IO: AddInputCharacter() goes into a queue which can receive as many characters as needed during the frame. This is useful + for automation to not have an upper limit on typing speed. Will later transition key/mouse to use the event queue later. +- Style: Tweaked default value of style.DisplayWindowPadding from (20,20) to (19,19) so the default style as a value + which is the same as the title bar height. +- Demo: "Simple Layout" and "Style Editor" are now using tabs. +- Demo: Added a few more things under "Child windows" (changing ImGuiCol_ChildBg, positioning child, using IsItemHovered after a child). +- Examples: DirectX10/11/12: Made imgui_impl_dx10/dx11/dx12.cpp link d3dcompiler.lib from the .cpp file to ease integration. +- Examples: Allegro 5: Properly destroy globals on shutdown to allow for restart.

(#2066) +- Nav, Focus: Fixed ImGuiWindowFlags_NoBringToFrontOnFocus windows not being restoring focus + properly after the main menu bar or last focused window is deactivated. +- Nav: Fixed an assert in certain circumstance (mostly when using popups) when mouse positions stop being valid. (#2168) +- Nav: Fixed explicit directional input not re-highlighting current nav item if there is a single item in the window + and highlight has been previously disabled by the mouse. (#787) +- DragFloat: Fixed a situation where dragging with value rounding enabled or with a power curve + erroneously wrapped the value to one of the min/max edge.

(#2150) [@podsvirov] +- Window: Resizing from edges (with io.ConfigResizeWindowsFromEdges Beta flag) extends the hit region + of root floating windows outside the window, making it easier to resize windows. Resize grips are also + extended accordingly so there are no discontinuity when hovering between borders and corners. (#1495, #822) +- Window: Added ImGuiWindowFlags_NoBackground flag to avoid rendering window background.

This was undoing an intentional change + introduced in 1.50 and broken in 1.60. (#1698, #894, #713). +- TextUnformatted(): Fixed a case where large-text path would read bytes past the text_end marker depending + on the position of new lines in the buffer (it wasn't affecting the output but still not the right thing to do!) +- ListBox(): Fixed frame sizing when items_count==1 unnecessarily showing a scrollbar. (#2173) [@luk1337, @ocornut] +- ListBox(): Tweaked frame sizing so list boxes will look more consistent when FramePadding is far from ItemSpacing. +- RenderText(): Some optimization for very large text buffers, useful for non-optimized builds. +- BeginMenu(): Fixed menu popup horizontal offset being off the item in the menu bar when WindowPadding=0.0f. +- ArrowButton(): Fixed arrow shape being horizontally misaligned by (FramePadding.y-FramePadding.x) if they are different. +- Demo: Split the contents of ShowDemoWindow() into smaller functions as it appears to speed up link time with VS. (#2152) +- Drag and Drop: Added GetDragDropPayload() to peek directly into the payload (if any) from anywhere. (#143) +- ImGuiTextBuffer: Avoid heap allocation when empty. +- ImDrawList: Fixed AddConvexPolyFilled() undefined behavior when passing points_count smaller than 3, + in particular, points_count==0 could lead to a memory stomp if the draw list was previously empty. +- Examples: DirectX10, DirectX11: Removed seemingly unnecessary calls to invalidate and recreate device objects + in the WM_SIZE handler. (#2088) [@ice1000] +- Examples: GLFW: User previously installed GLFW callbacks are now saved and chain-called by the default callbacks. (#1759) +- Examples: OpenGL3: Added support for GL 4.5's glClipControl(GL_UPPER_LEFT). (#2186) +- Examples: OpenGL3+GLFW: Fixed error condition when using the GLAD loader. (#2157) [@blackball] +- Examples: OpenGL3+GLFW/SDL: Made main.cpp compile with IMGUI_IMPL_OPENGL_LOADER_CUSTOM (may be missing init). (#2178) [@doug-moen] +- Examples: SDL2+Vulkan: Fixed application shutdown which could deadlock on Linux + Xorg.

If you were conveniently using the imgui copy of those + STB headers in your project, you will have to update your include paths. (#1718, #2036) + The reason for this change is to avoid conflicts for projects that may also be importing + their own copy of the STB libraries. Note that imgui's copy of stb_textedit.h is modified. +- Renamed io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) + +Other Changes: + +- This is a minor release following the 1.64 refactor, with a little more shuffling of code. +- Clarified and improved the source code sectioning in all files (easier to search or browse sections). +- Nav: Removed the [Beta] tag from various descriptions of the gamepad/keyboard navigation system. + Although it is not perfect and will keep being improved, it is fairly functional and used by many. (#787) +- Fixed a build issue with non-Cygwin GCC under Windows. +- Demo: Added a "Configuration" block to make io.ConfigFlags/io.BackendFlags more prominent. +- Examples: OpenGL3+SDL2: Fixed error condition when using the GLAD loader.

THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTIONS HAS BEEN MOVED. + Because of this, any local modifications to imgui.cpp will likely conflict when you update. + If you have any modifications to imgui.cpp, it is suggested that you first update to 1.63, then + isolate your patches. You can peak at imgui_widgets.cpp from 1.64 to get a sense of what is included in it, + then separate your changes into several patches that can more easily be applied to 1.64 on a per-file basis. + What I found worked nicely for me, was to open the diff of the old patches in an interactive merge/diff tool, + search for the corresponding function in the new code and apply the chunks manually. +- As a reminder, if you have any change to imgui.cpp it is a good habit to discuss them on the github, + so a solution applicable on the Master branch can be found. If your company has changes that you cannot + disclose you may also contact me privately. + + +----------------------------------------------------------------------- + VERSION 1.63 (Released 2018-08-29) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.63 + +Breaking Changes: + +- Style: Renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. + Kept redirection enum (will obsolete). +- Changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecision over time. +- Removed per-window ImGuiWindowFlags_ResizeFromAnySide Beta flag in favor `io.ConfigResizeWindowsFromEdges=true` to + enable the feature globally. (#1495) + The feature is not currently enabled by default because it is not satisfying enough, but will eventually be. +- InputText: Renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData + for consistency. Kept redirection types (will obsolete). +- InputText: Removed ImGuiTextEditCallbackData::ReadOnly because it is a duplication of (::Flags & ImGuiInputTextFlags_ReadOnly). +- Renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. + Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent). +- Renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to + io.ConfigMacOSXBehaviors for consistency. (#1427, #473) +- Removed obsolete redirection functions: CollapsingHeader() variation with 2 bools - marked obsolete in v1.49, May 2016. + +Other Changes: + +- ArrowButton: Fixed to honor PushButtonRepeat() setting (and internals' ImGuiItemFlags_ButtonRepeat). +- ArrowButton: Setup current line text baseline so that ArrowButton() + SameLine() + Text() are aligned properly. +- Nav: Added a CTRL+TAB window list and changed the highlight system accordingly. The change is motivated by upcoming + Docking features. (#787) +- Nav: Made CTRL+TAB skip menus + skip the current navigation window if is has the ImGuiWindow_NoNavFocus set. (#787) + While it was previously possible, you won't be able to CTRL-TAB out and immediately back in a window with the + ImGuiWindow_NoNavFocus flag. +- Window: Allow menu and popups windows from ignoring the style.WindowMinSize values so short menus/popups are not padded. (#1909) +- Window: Added global io.ConfigResizeWindowsFromEdges option to enable resizing windows from their edges and from + the lower-left corner. (#1495) +- Window: Collapse button shows hovering highlight + clicking and dragging on it allows to drag the window as well. +- Added IsItemEdited() to query if the last item modified its value (or was pressed). This is equivalent to the bool + returned by most widgets. + It is useful in some situation e.g. using InputText() with ImGuiInputTextFlags_EnterReturnsTrue. (#2034) +- InputText: Added support for buffer size/capacity changes via the ImGuiInputTextFlags_CallbackResize flag. (#2006, #1443, #1008). +- InputText: Fixed not tracking the cursor horizontally when modifying the text buffer through a callback. +- InputText: Fixed minor off-by-one issue when submitting a buffer size smaller than the initial zero-terminated buffer contents. +- InputText: Fixed a few pathological crash cases on single-line InputText widget with multiple millions characters worth of contents. + Because the current text drawing function reserve for a worst-case amount of vertices and how we handle horizontal clipping, + we currently just avoid displaying those single-line widgets when they are over a threshold of 2 millions characters, + until a better solution is found. +- Drag and Drop: Fixed an incorrect assert when dropping a source that is submitted after the target (bug introduced with 1.62 changes + related to the addition of IsItemDeactivated()). (#1875, #143) +- Drag and Drop: Fixed ImGuiDragDropFlags_SourceNoDisableHover to affect hovering state prior to calling IsItemHovered() + fixed description. (#143) +- Drag and Drop: Calling BeginTooltip() between a BeginDragSource()/EndDragSource() or BeginDropTarget()/EndDropTarget() uses adjusted tooltip + settings matching the one created when calling BeginDragSource() without the ImGuiDragDropFlags_SourceNoPreviewTooltip flag. (#143) +- Drag and Drop: Payload stays available and under the mouse if the source stops being submitted, however the tooltip is replaced by "...". (#1725) +- Drag and Drop: Added ImGuiDragDropFlags_SourceAutoExpirePayload flag to force payload to expire if the source stops being submitted. (#1725, #143). +- IsItemHovered(): Added ImGuiHoveredFlags_AllowWhenDisabled flag to query hovered status on disabled items. (#1940, #211) +- Selectable: Added ImGuiSelectableFlags_Disabled flag in the public API. (#211) +- ColorEdit4: Fixed a bug when text input or drag and drop leading to unsaturated HSV values would erroneously alter the resulting color. (#2050) +- Misc: Added optional misc/stl/imgui_stl.h wrapper to use with STL types (e.g. InputText with std::string). (#2006, #1443, #1008) + [*EDIT* renamed to misc/std/imgui_stdlib.h in 1.66] +- Misc: Added IMGUI_VERSION_NUM for easy compile-time testing. (#2025) +- Misc: Added ImGuiMouseCursor_Hand cursor enum + corresponding software cursor. (#1913, 1914) [@aiekick, @ocornut] +- Misc: Tweaked software mouse cursor offset to match the offset of the corresponding Windows 10 cursors. +- Made assertion more clear when trying to call Begin() outside of the NewFrame()..EndFrame() scope. (#1987) +- Fixed assertion when transitioning from an active ID to another within a group, affecting ColorPicker (broken in 1.62). (#2023, #820, #956, #1875). +- Fixed PushID() from keeping alive the new ID Stack top value (if a previously active widget shared the ID it would be erroneously kept alive). +- Fixed horizontal mouse wheel not forwarding the request to the parent window if ImGuiWindowFlags_NoScrollWithMouse is set. (#1463, #1380, #1502) +- Fixed a include build issue for Cygwin in non-POSIX (Win32) mode. (#1917, #1319, #276) +- ImDrawList: Improved handling for worst-case vertices reservation policy when large amount of text (e.g. 1+ million character strings) + are being submitted in a single call. It would typically have crashed InputTextMultiline(). (#200) +- OS/Windows: Fixed missing ImmReleaseContext() call in the default Win32 IME handler. (#1932) [@vby] +- Metrics: Changed io.MetricsActiveWindows to reflect the number of active windows (!= from visible windows), which is useful + for lazy/idle render mechanisms as new windows are typically not visible for one frame. +- Metrics: Added io.MetricsRenderWindow to reflect the number of visible windows. +- Metrics: Added io.MetricsActiveAllocations, moving away from the cross-context global counters than we previously used. (#1565, #1599, #586) +- Demo: Added basic Drag and Drop demo. (#143) +- Demo: Modified the Console example to use InsertChars() in the input text callback instead of poking directly into the buffer. + Although this won't make a difference in the example itself, using InsertChars() will honor the resizing callback properly. (#2006, #1443, #1008). +- Demo: Clarified the use of IsItemHovered()/IsItemActive() right after being in the "Active, Focused, Hovered & Focused Tests" section. +- Examples: Tweaked the main.cpp of each example. +- Examples: Metal: Added Metal rendering backend. (#1929, #1873) [@warrenm] +- Examples: OSX: Added early raw OSX platform backend. (#1873) [@pagghiu, @itamago, @ocornut] +- Examples: Added mac OSX & iOS + Metal example in example_apple_metal/. (#1929, #1873) [@warrenm] +- Examples: Added mac OSX + OpenGL2 example in example_apple_opengl2/. (#1873) +- Examples: OpenGL3: Added shaders more versions of GLSL. (#1938, #1941, #1900, #1513, #1466, etc.) +- Examples: OpenGL3: Tweaked the imgui_impl_opengl3.cpp to work as-is with Emscripten + WebGL 2.0. (#1941). [@o-micron] +- Examples: OpenGL3: Made the example app default to GL 3.0 + GLSL 130 (instead of GL 3.2 + GLSL 150) unless on Mac. +- Examples: OpenGL3: Added error output when shaders fail to compile/link. +- Examples: OpenGL3: Added support for glew and glad OpenGL loaders out of the box. (#2001, #2002) [@jdumas] +- Examples: OpenGL2: Disabling/restoring GL_LIGHTING and GL_COLOR_MATERIAL to increase compatibility with legacy OpenGL applications. (#1996) +- Examples: DirectX10, DirectX11: Fixed unreleased resources in Init and Shutdown functions. (#1944) +- Examples: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility. (#1989) [@matt77hias] +- Examples: Vulkan: Fixed handling of VkSurfaceCapabilitiesKHR::maxImageCount = 0 case. Tweaked present mode selections. +- Examples: Win32, Glfw, SDL: Added support for the ImGuiMouseCursor_Hand cursor. + + +----------------------------------------------------------------------- + VERSION 1.62 (Released 2018-06-22) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.62 + +Breaking Changes: + +- TreeNodeEx(): The helper ImGuiTreeNodeFlags_CollapsingHeader flag now include ImGuiTreeNodeFlags_NoTreePushOnOpen. + The flag was already set by CollapsingHeader(). + The only difference is if you were using TreeNodeEx() manually with ImGuiTreeNodeFlags_CollapsingHeader and without + ImGuiTreeNodeFlags_NoTreePushOnOpen. In this case you can remove the ImGuiTreeNodeFlags_NoTreePushOnOpen flag from + your call (ImGuiTreeNodeFlags_CollapsingHeader & ~ImGuiTreeNodeFlags_NoTreePushOnOpen). (#1864) + This also apply if you were using internal's TreeNodeBehavior() with the ImGuiTreeNodeFlags_CollapsingHeader flag directly. +- ImFontAtlas: Renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish new smaller variants and + discourage using the full set. (#1859) + +Other Changes: + +- Examples backends have been refactored to separate the platform code (e.g. Win32, Glfw, SDL2) from the renderer code (e.g. DirectX11, OpenGL3, Vulkan). + The "Platform" backends are in charge of: mouse/keyboard/gamepad inputs, cursor shape, timing, etc. + The "Renderer" backends are in charge of: creating the main font texture, rendering imgui draw data. + before: imgui_impl_dx11.cpp --> after: imgui_impl_win32.cpp + imgui_impl_dx11.cpp + before: imgui_impl_dx12.cpp --> after: imgui_impl_win32.cpp + imgui_impl_dx12.cpp + before: imgui_impl_glfw_gl3.cpp --> after: imgui_impl_glfw.cpp + imgui_impl_opengl2.cpp + before: imgui_impl_glfw_vulkan.cpp --> after: imgui_impl_glfw.cpp + imgui_impl_vulkan.cpp + before: imgui_impl_sdl_gl3.cpp --> after: imgui_impl_sdl2.cpp + imgui_impl_opengl2.cpp + before: imgui_impl_sdl_gl3.cpp --> after: imgui_impl_sdl2.cpp + imgui_impl_opengl3.cpp etc. + - The idea is what we can now easily combine and maintain backends and reduce code redundancy. Individual files are + smaller and more reusable. Integration of imgui into a new/custom engine may also be easier as there is less overlap + between "windowing / inputs" and "rendering" code, so you may study or grab one half of the code and not the other. + - This change was motivated by the fact that adding support for the upcoming multi-viewport feature requires more work + from the Platform and Renderer backends, and the amount of redundancy across files was becoming too difficult to + maintain. If you use default backends, you'll benefit from an easy update path to support multi-viewports later + (for future ImGui 1.7x). + - This is not strictly a breaking change if you keep your old backends, but when you'll want to fully update your backends, + expect to have to reshuffle a few things. + - Each example still has its own main.cpp which you may refer you to understand how to initialize and glue everything together. + - Some frameworks (such as the Allegro, Marmalade) handle both the "platform" and "rendering" part, and your custom engine may as well. + - Read examples/README.txt for details. +- Added IsItemDeactivated() to query if the last item was active previously and isn't anymore. Useful for Undo/Redo patterns. (#820, #956, #1875) +- Added IsItemDeactivatedAfterChange() [*EDIT* renamed to IsItemDeactivatedAfterEdit() in 1.63] if the last item was active previously, + is not anymore, and during its active state modified a value. Note that you may still get false positive (e.g. drag value and while + holding return on the same value). (#820, #956, #1875) +- Nav: Added support for PageUp/PageDown (explorer-style: first aim at bottom/top most item, when scroll a page worth of contents). (#787) +- Nav: To keep the navigated item in view we also attempt to scroll the parent window as well as the current window. (#787) +- ColorEdit3, ColorEdit4, ColorButton: Added ImGuiColorEditFlags_NoDragDrop flag to disable ColorEditX as drag target and ColorButton as drag source. (#1826) +- BeginDragDropSource(): Offset tooltip position so it is off the mouse cursor, but also closer to it than regular tooltips, + and not clamped by viewport. (#1739) +- BeginDragDropTarget(): Added ImGuiDragDropFlags_AcceptNoPreviewTooltip flag to request hiding the drag source tooltip + from the target site. (#143) +- BeginCombo(), BeginMainMenuBar(), BeginChildFrame(): Temporary style modification are restored at the end of BeginXXX + instead of EndXXX, to not affect tooltips and child windows. +- Popup: Improved handling of (erroneously) repeating calls to OpenPopup() to not close the popup's child popups. (#1497, #1533, #1865). +- InputTextMultiline(): Fixed double navigation highlight when scrollbar is active. (#787) +- InputText(): Fixed Undo corruption after pasting large amount of text (Redo will still fail when undo buffers are exhausted, + but text won't be corrupted). +- SliderFloat(): When using keyboard/gamepad and a zero precision format string (e.g. "%.0f"), always step in integer units. (#1866) +- ImFontConfig: Added GlyphMinAdvanceX/GlyphMaxAdvanceX settings useful to make a font appears monospaced, particularly useful + for icon fonts. (#1869) +- ImFontAtlas: Added GetGlyphRangesChineseSimplifiedCommon() helper that returns a list of ~2500 most common Simplified Chinese + characters. (#1859) [@JX-Master, @ocornut] +- Examples: OSX: Added imgui_impl_osx.mm backend to be used along with e.g. imgui_impl_opengl2.cpp. (#281, #1870) [@pagghiu, @itamago, @ocornut] +- Examples: GLFW: Made it possible to Shutdown/Init the backend again (by resetting the time storage properly). (#1827) [@ice1000] +- Examples: Win32: Fixed handling of mouse wheel messages to support sub-unit scrolling messages (typically sent by track-pads). (#1874) [@zx64] +- Examples: SDL+Vulkan: Added SDL+Vulkan example. +- Examples: Allegro5: Added support for ImGuiConfigFlags_NoMouseCursorChange flag. Added clipboard support. +- Examples: Allegro5: Unindexing buffers ourselves as Allegro indexed drawing primitives are buggy in the DirectX9 backend + (will be fixed in Allegro 5.2.5+). +- Examples: DirectX12: Moved the ID3D12GraphicsCommandList* parameter from ImGui_ImplDX12_NewFrame() to ImGui_ImplDX12_RenderDrawData() which makes a lots more sense. (#301) +- Examples: Vulkan: Reordered parameters ImGui_ImplVulkan_RenderDrawData() to be consistent with other backends, + a good occasion since we refactored the code. +- Examples: FreeGLUT: Added FreeGLUT backends. Added FreeGLUT+OpenGL2 example. (#801) +- Examples: The functions in imgui_impl_xxx.cpp are prefixed with IMGUI_IMPL_API (which defaults to IMGUI_API) to facilitate + some uses. (#1888) +- Examples: Fixed backends to use ImGuiMouseCursor_COUNT instead of old name ImGuiMouseCursor_Count_ so they can compile + with IMGUI_DISABLE_OBSOLETE_FUNCTIONS. (#1887) +- Misc: Updated stb_textedit from 1.09 + patches to 1.12 + minor patches. +- Internals: PushItemFlag() flags are inherited by BeginChild(). + + +----------------------------------------------------------------------- + VERSION 1.61 (Released 2018-05-14) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.61 + +Breaking Changes: + +- DragInt(): The default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally + any more. If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format. + To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, + giving time to users to upgrade their code. + If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your + codebase for e.g. "DragInt.*%f" to you find them. +- InputFloat(): Obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more + flexible "const char* format", consistent with other functions. Kept redirection functions (will obsolete). +- Misc: IM_DELETE() helper function added in 1.60 doesn't set the input pointer to NULL, more consistent with standard + expectation and allows passing r-values. + +Other Changes: + +- Added DragScalar, DragScalarN: supports signed/unsigned, 32/64 bits, float/double data types. (#643, #320, #708, #1011) +- Added InputScalar, InputScalarN: supports signed/unsigned, 32/64 bits, float/double data types. (#643, #320, #708, #1011) +- Added SliderScalar, SliderScalarN: supports signed/unsigned, 32/64 bits, float/double data types. (#643, #320, #708, #1011) +- Window: Fixed pop-ups/tooltips/menus not honoring style.DisplaySafeAreaPadding as well as it should have (part of menus + displayed outside the safe area, etc.). +- Window: Fixed windows using the ImGuiWindowFlags_NoSavedSettings flag from not using the same default position as other windows. (#1760) +- Window: Relaxed the internal stack size checker to allow Push/Begin/Pop/.../End patterns to be used with PushStyleColor, PushStyleVar, PushFont without causing a false positive assert. (#1767) +- Window: Fixed the default proportional item width lagging by one frame on resize. +- Columns: Fixed a bug introduced in 1.51 where columns would affect the contents size of their container, often creating + feedback loops when ImGuiWindowFlags_AlwaysAutoResize was used. (#1760) +- Settings: Fixed saving an empty .ini file if CreateContext/DestroyContext are called without a single call to NewFrame(). (#1741) +- Settings: Added LoadIniSettingsFromDisk(), LoadIniSettingsFromMemory(), SaveIniSettingsToDisk(), SaveIniSettingsToMemory() + to manually load/save .ini settings. (#923, #993) +- Settings: Added io.WantSaveIniSettings flag, which is set to notify the application that e.g. SaveIniSettingsToMemory() + should be called. (#923, #993) +- Scrolling: Fixed a case where using SetScrollHere(1.0f) at the bottom of a window on the same frame the window height + has been growing would have the scroll clamped using the previous height. (#1804) +- MenuBar: Made BeginMainMenuBar() honor style.DisplaySafeAreaPadding so the text can be made visible on TV settings that + don't display all pixels. (#1439) [@dougbinks] +- InputText: On Mac OS X, filter out characters when the CMD modifier is held. (#1747) [@sivu] +- InputText: On Mac OS X, support CMD+SHIFT+Z for Redo. CMD+Y is also supported as major apps seems to default to support both. (#1765) [@lfnoise] +- InputText: Fixed returning true when edition is cancelled with ESC and the current buffer matches the initial value. +- InputFloat,InputFloat2,InputFloat3,InputFloat4: Added variations taking a more flexible and consistent optional + "const char* format" parameter instead of "int decimal_precision". This allow using custom formats to display values + in scientific notation, and is generally more consistent with other API. + Obsoleted functions using the optional "int decimal_precision" parameter. (#648, #712) +- DragFloat, DragInt: Cancel mouse tweak when current value is initially past the min/max boundaries and mouse is pushing + in the same direction (keyboard/gamepad version already did this). +- DragFloat, DragInt: Honor natural type limits (e.g. INT_MAX, FLT_MAX) instead of wrapping around. (#708, #320) +- DragFloat, SliderFloat: Fixes to allow input of scientific notation numbers when using CTRL+Click to input the value. (~#648, #1011) +- DragFloat, SliderFloat: Rounding-on-write uses the provided format string instead of parsing the precision from the string, + which allows for finer uses of %e %g etc. (#648, #642) +- DragFloat: Improved computation when using the power curve. Improved lost of input precision with very small steps. + Added an assert than power-curve requires a min/max range. (~#642) +- DragFloat: The 'power' parameter is only honored if the min/max parameter are also setup. +- DragInt, SliderInt: Fixed handling of large integers (we previously passed data around internally as float, which reduced + the range of valid integers). +- ColorEdit: Fixed not being able to pass the ImGuiColorEditFlags_NoAlpha or ImGuiColorEditFlags_HDR flags to SetColorEditOptions(). +- Nav: Fixed hovering a Selectable() with the mouse so that it update the navigation cursor (as it happened in the pre-1.60 navigation branch). (#787) +- Style: Changed default style.DisplaySafeAreaPadding values from (4,4) to (3,3) so it is smaller than FramePadding and has no effect on main menu bar on a computer. (#1439) +- Fonts: When building font atlas, glyphs that are missing in the fonts are not using the glyph slot to render the default glyph. Saves space and allow merging fonts with + overlapping font ranges such as FontAwesome5 which split out the Brands separately from the Solid fonts. (#1703, #1671) +- Misc: Added IMGUI_CHECKVERSION() macro to compare version string and data structure sizes in order to catch issues with mismatching compilation unit settings. (#1695, #1769) +- Misc: Added IMGUI_DISABLE_MATH_FUNCTIONS in imconfig.h to make it easier to redefine wrappers for std/crt math functions. +- Misc: Fix to allow compiling in unity builds where stb_rectpack/stb_truetype may be already included in the same compilation unit. +- Demo: Simple Overlay: Added a context menu item to enable freely moving the window. +- Demo: Added demo for DragScalar(), InputScalar(), SliderScalar(). (#643) +- Examples: Calling IMGUI_CHECKVERSION() in the main.cpp of every example application. +- Examples: Allegro 5: Added support for 32-bit indices setup via defining ImDrawIdx, to avoid an unnecessary conversion (Allegro 5 doesn't support 16-bit indices). +- Examples: Allegro 5: Renamed backend from imgui_impl_a5.cpp to imgui_impl_allegro5.cpp. +- Examples: DirectX 9: Saving/restoring Transform because they don't seem to be included in the StateBlock. Setting shading mode to Gouraud. (#1790, #1687) [@sr-tream] +- Examples: SDL: Fixed clipboard paste memory leak in the SDL backend code.

If you are using an old backend from the examples/ folder, remove the line that calls Shutdown(). + - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance. + - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts. + - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts. +- Renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums. +- Fonts: Moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths. +- Fonts: Changed ImFont::DisplayOffset.y to defaults to 0 instead of +1. Fixed vertical rounding of Ascent/Descent to match TrueType renderer. + If you were adding or subtracting (not assigning) to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. (#1619) +- BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment. +- Obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete). +- Obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete). +- Renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, not used by core, and honored by some backend ahead of merging the Nav branch). +- Removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered style colors as the closing cross uses regular button colors now. +- Renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData. +- Removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it should be easy to replicate on your side (you can find the code in 1.53). +- [EDITED] Window: BeginChild() with an explicit name doesn't include the hash within the internal window name. (#1698) + This change was erroneously introduced, undoing the change done for #894, #713, and not documented properly in the original + 1.60 release Changelog. It was fixed on 2018-09-28 (1.66) and I wrote this paragraph the same day. + +Other Changes: + +- Doc: Added a Changelog file in the repository to ease comparing versions (it goes back to dear imgui 1.48), until now it was only on GitHub. +- Navigation: merged in the gamepad/keyboard navigation (about a million changes!). (#787, #323) + The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable. +- To use Gamepad Navigation: + - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable. + - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + fill the io.NavInputs[] fields before calling NewFrame(). Read imgui.cpp for more details. + - See https://github.com/ocornut/imgui/issues/1599 for recommended gamepad mapping or download PNG/PSD at http://goo.gl/9LgVZW + - See 'enum ImGuiNavInput_' in imgui.h for a description of inputs. Read imgui.cpp for more details. +- To use Keyboard Navigation: + - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable. NewFrame() will automatically fill io.NavInputs[] based on your io.KeysDown[] + io.KeyMap[] arrays. + - Basic controls: arrows to navigate, Alt to enter menus, Space to activate item, Enter to edit text, Escape to cancel/close, Ctrl-Tab to focus windows, etc. + - When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard), the io.WantCaptureKeyboard flag will be set. + For more advanced uses, you may want to read from io.NavActive or io.NavVisible. Read imgui.cpp for more details. +- Navigation: SetItemDefaultFocus() sets the navigation position in addition to scrolling. (#787) +- Navigation: Added IsItemFocused(), added IsAnyItemFocused(). (#787) +- Navigation: Added window flags: ImGuiWindowFlags_NoNav (== ImGuiWindowFlags_NoNavInputs | ImGuiWindowFlags_NoNavFocus). +- Navigation: Style: Added ImGuiCol_NavHighlight, ImGuiCol_NavWindowingHighlight colors. (#787) +- Navigation: TreeNode: Added ImGuiTreeNodeFlags_NavLeftJumpsBackHere flag to allow Nav Left direction to jump back to parent tree node from any of its child. (#1079) +- Navigation: IO: Added io.ConfigFlags (input), io.NavActive (output), io.NavVisible (output). (#787) +- Context: Removed the default global context and font atlas instances, which caused various problems to users of multiple contexts and DLL users. (#1565, #1599) + YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END. Existing apps will assert/crash without it. +- Context: Added SetAllocatorFunctions() to rewire memory allocators (as a replacement to previous parameters to CreateContext()). Allocators are shared by all contexts and imgui helpers. (#1565, #586, #992, #1007, #1558) +- Context: You may pass a ImFontAtlas to CreateContext() to specify a font atlas to share. Shared font atlas are not owned by the context and not destroyed along with it. (#1599) +- Context: Added IMGUI_DISABLE_DEFAULT_ALLOCATORS to disable linking with malloc/free. (#1565, #586, #992, #1007, #1558) +- IO: Added io.ConfigFlags for user application to store settings for imgui and for the backend: + - ImGuiConfigFlags_NavEnableKeyboard: Enable keyboard navigation. + - ImGuiConfigFlags_NavEnableGamepad: Enable gamepad navigation (provided ImGuiBackendFlags_HasGamepad is also set by backend). + - ImGuiConfigFlags_NavEnableSetMousePos: Instruct navigation to move the mouse cursor. May be useful on TV/console systems where moving a virtual mouse is awkward. + - ImGuiConfigFlags_NoMouseCursorChange: Instruct backend to not alter mouse cursor shape and visibility (by default the example backend use mouse cursor API of the platform when available) + - ImGuiConfigFlags_NoMouse: Instruct imgui to clear mouse position/buttons in NewFrame(). This allows ignoring the mouse information passed by the backend. + - ImGuiConfigFlags_IsSRGB, ImGuiConfigFlags_IsTouchScreen: Flags for general application use. +- IO: Added io.BackendFlags for backend to store its capabilities (currently: _HasGamepad, _HasMouseCursors, _HasSetMousePos). This will be used more in the next version. +- IO: Added ImGuiKey_Insert, ImGuiKey_Space keys. Setup in all example backends. (#1541) +- IO: Added Horizontal Mouse Wheel support for horizontal scrolling. (#1463) [@tseeker] +- IO: Added IsAnyMouseDown() helper which is helpful for backends to handle mouse capturing. +- Window: Clicking on a window with the ImGuiWIndowFlags_NoMove flags takes an ActiveId so we can't hover something else when dragging afterwards. (#1381, #1337) +- Window: IsWindowHovered(): Added ImGuiHoveredFlags_AnyWindow, ImGuiFocusedFlags_AnyWindow flags (See Breaking Changes). Added to demo. (#1382) +- Window: Added SetNextWindowBgAlpha() helper. Particularly helpful since the legacy 5-parameters version of Begin() has been marked as obsolete in 1.53. (#1567) +- Window: Fixed SetNextWindowContentSize() with 0.0f on Y axis (or SetNextWindowContentWidth()) overwriting the contents size. Got broken on Dec 10 (1.53). (#1363) +- ArrowButton: Added ArrowButton() given a cardinal direction (e.g. ImGuiDir_Left). +- InputText: Added alternative clipboard shortcuts: Shift+Delete (cut), CTRL+Insert (copy), Shift+Insert (paste). (#1541) +- InputText: Fixed losing Cursor X position when clicking outside on an item that's submitted after the InputText(). It was only noticeable when restoring focus programmatically. (#1418, #1554) +- InputText: Added ImGuiInputTextFlags_CharsScientific flag to also allow 'e'/'E' for input of values using scientific notation. Automatically used by InputFloat. +- Style: Default style is now StyleColorsDark(), instead of the old StyleColorsClassic(). (#707) +- Style: Enable window border by default. (#707) +- Style: Exposed ImGuiStyleVar_WindowTitleAlign, ImGuiStyleVar_ScrollbarSize, ImGuiStyleVar_ScrollbarRounding, ImGuiStyleVar_GrabRounding + added an assert to reduce accidental breakage. (#1181) +- Style: Added style.MouseCursorScale help when using the software mouse cursor facility. (#939). +- Style: Close button nows display a cross before hovering. Fixed cross positioning being a little off. Uses button colors for highlight when hovering. (#707) +- Popup: OpenPopup() Always reopen existing pop-ups. (Removed imgui_internal.h's OpenPopupEx() which was used for this.) (#1497, #1533). +- Popup: BeginPopupContextItem(), BeginPopupContextWindow(), BeginPopupContextVoid(), OpenPopupOnItemClick() all react on mouse release instead of mouse press. (~#439) +- Popup: Better handling of user mistakenly calling OpenPopup() every frame (with reopen_existing option). The error will now be more visible and easier to understand. (#1497) +- Popup: BeginPopup(): Exposed extra_flags parameter that are passed through to Begin(). (#1533) +- Popup: BeginPopupModal: fixed the conditional test for SetNextWindowPos() which was polling the wrong window, which in practice made the test succeed all the time. +- Tooltip: BeginTooltip() sets ImGuiWindowFlags_NoInputs flag. +- Scrollbar: Fixed ScrollbarY enable test after ScrollbarX has been enabled being a little off (small regression from Nov 2017). (#1574) +- Scrollbar: Fixed ScrollbarX enable test subtracting WindowPadding.x (this has been there since the addition of horizontal scroll bar!). +- Columns: Clear offsets data when columns count changed. (#1525) +- Columns: Fixed a memory leak of ImGuiColumnsSet's Columns vector. (#1529) [@unprompted] +- Columns: Fixed resizing a window very small breaking some columns positioning (broken in 1.53). +- Columns: The available column extent takes consideration of the right-most clipped pixel, so the right-most column may look a little wider but will contain the same amount of visible contents. +- MenuBar: Fixed menu bar pushing a clipping rect outside of its allocated bound (usually unnoticeable). +- TreeNode: nodes with the ImGuiTreeNodeFlags_Leaf flag correctly disable highlight when DragDrop is active. (#143, #581) +- Drag and Drop: Increased payload type string to 32 characters instead of 8. (#143) +- Drag and Drop: TreeNode as drop target displays rectangle over full frame. (#1597, #143) +- DragFloat: Fix/workaround for backends which do not preserve a valid mouse position when dragged out of bounds. (#1559) +- InputFloat: Allow inputing value using scientific notation e.g. "1e+10". +- InputDouble: Added InputDouble() function. We use a format string instead of a decimal_precision parameter to also for "%e" and variants. (#1011) +- Slider, Combo: Use ImGuiCol_FrameBgHovered color when hovered. (#1456) [@stfx] +- Combo: BeginCombo(): Added ImGuiComboFlags_NoArrowButton to disable the arrow button and only display the wide value preview box. +- Combo: BeginCombo(): Added ImGuiComboFlags_NoPreview to disable the preview and only display a square arrow button. +- Combo: Arrow button isn't displayed over frame background so its blended color matches other buttons. Left side of the button isn't rounded. +- PlotLines: plot a flat line if scale_min==scale_max. (#1621) +- Fonts: Changed DisplayOffset.y to defaults to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. + If you were adding or subtracting (not assigning) to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. (#1619) +- Fonts: Updated stb_truetype from 1.14 to stb_truetype 1.19. (w/ include fix from some platforms #1622) +- Fonts: Added optional FreeType rasterizer in misc/freetype. Moved from imgui_club repo. (#618) [@Vuhdo, @mikesart, @ocornut] +- Fonts: Moved extra_fonts/ to misc/fonts/. +- ImFontAtlas: Fixed cfg.MergeMode not reusing existing glyphs if available (always overwrote). +- ImFontAtlas: Handle stb_truetype stbtt_InitFont() and stbtt_PackBegin() possible failures more gracefully, GetTexDataAsRGBA32() won't crash during conversion. (#1527) +- ImFontAtlas: Moved mouse cursor data out of ImGuiContext, fix drawing them with multiple contexts. Also remove the last remaining undesirable dependency on ImGui in imgui_draw.cpp. (#939) +- ImFontAtlas: Added ImFontAtlasFlags_NoPowerOfTwoHeight flag to disable padding font height to nearest power of two. (#1613) +- ImFontAtlas: Added ImFontAtlasFlags_NoMouseCursors flag to disable baking software mouse cursors, mostly to save texture memory on very low end hardware. (#1613) +- ImDrawList: Fixed AddRect() with anti-aliasing disabled (lower-right corner pixel was often missing, rounding looks a little better.) (#1646) +- ImDrawList: Added CloneOutput() helper to facilitate the cloning of ImDrawData or ImDrawList for multi-threaded rendering. +- Misc: Functions passed to libc qsort are explicitly marked cdecl to support compiling with vectorcall as the default calling convention. (#1230, #1611) [@RandyGaul] +- Misc: ImVec2: added [] operator. This is becoming desirable for some code working of either axes independently. Better adding it sooner than later. +- Misc: NewFrame(): Added an assert to detect incorrect filling of the io.KeyMap[] array earlier. (#1555) +- Misc: Added IM_OFFSETOF() helper in imgui.h (previously was in imgui_internal.h) +- Misc: Added IM_NEW(), IM_DELETE() helpers in imgui.h (previously were in imgui_internal.h) +- Misc: Added obsolete redirection function GetItemsLineHeightWithSpacing() (which redirects to GetFrameHeightWithSpacing()), as intended and stated in docs of 1.53. +- Misc: Added misc/natvis/imgui.natvis for visual studio debugger users to easily visualize imgui internal types. Added to examples projects. +- Misc: Added IMGUI_USER_CONFIG to define a custom configuration filename. (#255, #1573, #1144, #41) +- Misc: Added IMGUI_STB_TRUETYPE_FILENAME and IMGUI_STB_RECT_PACK_FILENAME compile time directives to use another version of the stb_ files. +- Misc: Updated stb_rect_pack from 0.10 to 0.11 (minor changes). + (Those flags are not used by ImGui itself, they only exists to make it easy for the engine/backend to pass information to the application in a standard manner.) +- Metrics: Added display of Columns state. +- Demo: Improved Selectable() examples. (#1528) +- Demo: Tweaked the Child demos, added a menu bar to the second child to test some navigation functions. +- Demo: Console: Using ImGuiCol_Text to be more friendly to color changes. +- Demo: Using IM_COL32() instead of ImColor() in ImDrawList centric contexts. Trying to phase out use of the ImColor helper whenever possible. +- Examples: Files in examples/ now include their own changelog so it is easier to occasionally update your backends if needed. +- Examples: Using Dark theme by default. (#707). Tweaked demo code. +- Examples: Added support for horizontal mouse wheel for API that allows it. (#1463) [@tseeker] +- Examples: All examples now setup the io.BackendFlags to signify they can honor mouse cursors, gamepad, etc. +- Examples: DirectX10: Fixed erroneous call to io.Fonts->ClearInputData() + ClearTexData() that was left in DX10 example but removed in 1.47 (Nov 2015) in every other backends. (#1733) +- Examples: DirectX12: Added DirectX 12 example. (#301) [@jdm3] +- Examples: OpenGL3+GLFW,SDL: Changed GLSL shader version from 330 to 150. (#1466, #1504) +- Examples: OpenGL3+GLFW,SDL: Added a way to override the GLSL version string in the Init function. (#1466, #1504). +- Examples: OpenGL3+GLFW,SDL: Creating VAO in the render function so it can be more easily used by multiple shared OpenGL contexts. (#1217) +- Examples: OpenGL3+GLFW: Using 3.2 context instead of 3.3. (#1466) +- Examples: OpenGL: Setting up glPixelStorei() explicitly before uploading texture. +- Examples: OpenGL: Calls to glPolygonMode() are casting parameters as GLEnum to not fail with more strict backends. (#1628) [@ilia-glushchenko] +- Examples: Win32 (DirectX9,10,11,12): Added support for mouse cursor shapes. (#1495) +- Examples: Win32 (DirectX9,10,11,12: Support for windows using the CS_DBLCLKS class flag by handling the double-click messages (WM_LBUTTONDBLCLK etc.). (#1538, #754) [@ndandoulakis] +- Examples: Win32 (DirectX9,10,11,12): Made the Win32 proc handlers not assert if there is no active context yet, to be more flexible with creation order. (#1565) +- Examples: GLFW: Added support for mouse cursor shapes (the diagonal resize cursors are unfortunately not supported by GLFW at the moment. (#1495) +- Examples: GLFW: Don't attempt to change the mouse cursor input mode if it is set to GLFW_CURSOR_DISABLED by the application. (#1202) [@PhilCK] +- Examples: SDL: Added support for mouse cursor shapes. (#1626) [@olls] +- Examples: SDL: Using SDL_CaptureMouse() to retrieve coordinates outside of client area when dragging (SDL 2.0.4+ only, otherwise using SDL_WINDOW_INPUT_FOCUS instead of previously SDL_WINDOW_MOUSE_FOCUS). (#1559) +- Examples: SDL: Enabled vsync by default so people don't come at us when the examples are running at 2000 FPS and burning a CPU core. +- Examples: SDL: Using SDL_GetPerformanceCounter() / SDL_GetPerformanceFrequency() to handle frame-rate over 1000 FPS properly. (#996) +- Examples: SDL: Using scan-code exclusively instead of a confusing mixture of scan-codes and key-codes. +- Examples: SDL: Visual Studio: Added .vcxproj file. Using %SDL2_DIR% in the default .vcxproj and build files instead of %SDL_DIR%, the earlier being more standard. +- Examples: Vulkan: Visual Studio: Added .vcxproj file. +- Examples: Apple: Fixed filenames in OSX xcode project. Various other Mac friendly fixes. [@gerryhernandez etc.] +- Examples: Visual Studio: Disabled extraneous function-level check in Release build. +- Various fixes, tweaks, internal refactoring, optimizations, comments. + + +----------------------------------------------------------------------- + VERSION 1.53 (Released 2017-12-25) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.53 + +Breaking Changes: + +- Renamed the emblematic `ShowTestWindow()` function to `ShowDemoWindow()`. Kept redirection function (will obsolete). +- Renamed `GetItemsLineHeightWithSpacing()` to `GetFrameHeightWithSpacing()` for consistency. Kept redirection function (will obsolete). +- Renamed `ImGuiTreeNodeFlags_AllowOverlapMode` flag to `ImGuiTreeNodeFlags_AllowItemOverlap`. Kept redirection enum (will obsolete). +- Obsoleted `IsRootWindowFocused()` in favor of using `IsWindowFocused(ImGuiFocusedFlags_RootWindow)`. Kept redirection function (will obsolete). (#1382) +- Obsoleted `IsRootWindowOrAnyChildFocused()` in favor of using `IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows)`. Kept redirection function (will obsolete). (#1382) +- Obsoleted `IsRootWindowOrAnyChildHovered()` in favor of using `IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows)`. Kept redirection function (will obsolete). (#1382) +- Obsoleted `SetNextWindowContentWidth() in favor of using `SetNextWindowContentSize()`. Kept redirection function (will obsolete). +- Renamed `ImGuiTextBuffer::append()` helper to `appendf()`, and `appendv()` to `appendfv()` for consistency. If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed. +- ImDrawList: Removed 'bool anti_aliased = true' final parameter of `ImDrawList::AddPolyline()` and `ImDrawList::AddConvexPolyFilled()`. Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame. +- Style, ImDrawList: Renamed `style.AntiAliasedShapes` to `style.AntiAliasedFill` for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags. +- Style, Begin: Removed `ImGuiWindowFlags_ShowBorders` window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. `style.FrameBorderSize`, `style.WindowBorderSize`, `style.PopupBorderSize`). + Use `ImGui::ShowStyleEditor()` to look them up. + Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. + It is recommended that you use the `StyleColorsClassic()`, `StyleColorsDark()`, `StyleColorsLight()` functions. Also see `ShowStyleSelector()`. +- Style: Removed `ImGuiCol_ComboBg` in favor of combo boxes using `ImGuiCol_PopupBg` for consistency. Combo are normal pop-ups. +- Style: Renamed `ImGuiCol_ChildWindowBg` to `ImGuiCol_ChildBg`. +- Style: Renamed `style.ChildWindowRounding` to `style.ChildRounding`, `ImGuiStyleVar_ChildWindowRounding` to `ImGuiStyleVar_ChildRounding`. +- Removed obsolete redirection functions: SetScrollPosHere() - marked obsolete in v1.42, July 2015. +- Removed obsolete redirection functions: GetWindowFont(), GetWindowFontSize() - marked obsolete in v1.48, March 2016. + +Other Changes: + +- Added `io.OptCursorBlink` option to allow disabling cursor blinking. (#1427) [renamed to io.ConfigCursorBlink in 1.63] +- Added `GetOverlayDrawList()` helper to quickly get access to a ImDrawList that will be rendered in front of every windows. +- Added `GetFrameHeight()` helper which returns `(FontSize + style.FramePadding.y * 2)`. +- Drag and Drop: Added Beta API to easily use drag and drop patterns between imgui widgets. + - Setup a source on a widget with `BeginDragDropSource()`, `SetDragDropPayload()`, `EndDragDropSource()` functions. + - Receive data with `BeginDragDropTarget()`, `AcceptDragDropPayload()`, `EndDragDropTarget()`. + - See ImGuiDragDropFlags for various options. + - The ColorEdit4() and ColorButton() widgets now support Drag and Drop. + - The API is tagged as Beta as it still may be subject to small changes. +- Drag and Drop: When drag and drop is active, tree nodes and collapsing header can be opened by hovering on them for 0.7 seconds. +- Renamed io.OSXBehaviors to io.OptMacOSXBehaviors. Should not affect users as the compile-time default is usually enough. (#473, #650) +- Style: Added StyleColorsDark() style. (#707) [@dougbinks] +- Style: Added StyleColorsLight() style. Best used with frame borders + thicker font than the default font. (#707) +- Style: Added style.PopupRounding setting. (#1112) +- Style: Added style.FrameBorderSize, style.WindowBorderSize, style.PopupBorderSize. Removed ImGuiWindowFlags_ShowBorders window flag! + Borders are now fully set up in the ImGuiStyle structure. Use ImGui::ShowStyleEditor() to look them up. (#707, fix #819, #1031) +- Style: Various small changes to the classic style (most noticeably, buttons are now using blue shades). (#707) +- Style: Renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg. +- Style: Renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding. +- Style: Removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency. (#707) +- Style: Made the ScaleAllSizes() helper rounds down every values so they are aligned on integers. +- Focus: Added SetItemDefaultFocus(), which in the current (master) branch behave the same as doing `if (IsWindowAppearing()) SetScrollHere()`. + In the navigation branch this will also set the default focus. Prefer using this when creating combo boxes with `BeginCombo()` so your code will be forward-compatible with gamepad/keyboard navigation features. (#787) +- Combo: Pop-up grows horizontally to accommodate for contents that is larger then the parent combo button. +- Combo: Added BeginCombo()/EndCombo() API which allows use to submit content of any form and manage your selection state without relying on indices. +- Combo: Added ImGuiComboFlags_PopupAlignLeft flag to BeginCombo() to prioritize keeping the pop-up on the left side (for small-button-looking combos). +- Combo: Added ImGuiComboFlags_HeightSmall, ImGuiComboFlags_HeightLarge, ImGuiComboFlags_HeightLargest to easily provide desired pop-up height. +- Combo: You can use SetNextWindowSizeConstraints() before BeginCombo() to specify specific pop-up width/height constraints. +- Combo: Offset popup position by border size so that a double border isn't so visible. (#707) +- Combo: Recycling windows by using a stack number instead of a unique id, wasting less memory (like menus do). +- InputText: Added ImGuiInputTextFlags_NoUndoRedo flag. (#1506, #1508) [@ibachar] +- Window: Fixed auto-resize allocating too much space for scrollbar when SizeContents is bigger than maximum window size (fixes c0547d3). (#1417) +- Window: Child windows with MenuBar use regular WindowPadding.y so layout look consistent as child or as a regular window. +- Window: Begin(): Fixed appending into a child window with a second Begin() from a different window stack querying the wrong window for the window->Collapsed test. +- Window: Calling IsItemActive(), IsItemHovered() etc. after a call to Begin() provides item data for the title bar, so you can easily test if the title bar is being hovered, etc. (#823) +- Window: Made it possible to use SetNextWindowPos() on a child window. +- Window: Fixed a one frame glitch. When an appearing window claimed the focus themselves, the title bar wouldn't use the focused color for one frame. +- Window: Added ImGuiWindowFlags_ResizeFromAnySide flag to resize from any borders or from the lower-left corner of a window. This requires your backend to honor GetMouseCursor() requests for full usability. (#822) +- Window: Sizing fixes when using SetNextWindowSize() on individual axises. +- Window: Hide new window for one frame until they calculate their size. Also fixes SetNextWindowPos() given a non-zero pivot. (#1694) +- Window: Made mouse wheel scrolling accommodate better to windows that are smaller than the scroll step. +- Window: SetNextWindowContentSize() adjust for the size of decorations (title bar/menu bar), but _not_ for borders are we consistently make borders not affect layout. + If you need a non-child window of an exact size with border enabled but zero window padding, you'll need to accommodate for the border size yourself. +- Window: Using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set. (#1380, #1502) +- Window: Active Modal window always set the WantCaptureKeyboard flag. (#744) +- Window: Moving window doesn't use accumulating MouseDelta so straying out of imgui boundaries keeps moved imgui window at the same cursor-relative position. +- IsWindowFocused(): Added ImGuiFocusedFlags_ChildWindows flag to include child windows in the focused test. (#1382). +- IsWindowFocused(): Added ImGuiFocusedFlags_RootWindow flag to start focused test from the root (top-most) window. Obsolete IsRootWindowFocused(). (#1382) +- IsWindowHovered(): Added ImGuiHoveredFlags_ChildWindows flag to include child windows in the hovered test. (#1382). +- IsWindowHovered(): Added ImGuiHoveredFlags_RootWindow flag to start hovered test from the root (top-most) window. The combination of both flags obsoletes IsRootWindowOrAnyChildHovered(). (#1382) +- IsWindowHovered(): Fixed return value when an item is active to use the same logic as IsItemHovered(). (#1382, #1404) +- IsWindowHovered(): Always return true when current window is being moved. (#1382) +- Scrollbar: Fixed issues with vertical scrollbar flickering/appearing, typically when manually resizing and using a pattern of filling available height (e.g. full sized BeginChild). +- Scrollbar: Minor graphical fix for when scrollbar don't have enough visible space to display the full grab. +- Scrolling: Fixed padding and scrolling asymmetry where lower/right sides of a window wouldn't use WindowPadding properly + causing minor scrolling glitches. +- Tree: TreePush with zero arguments was ambiguous. Resolved by making it call TreePush(const void*). [@JasonWilkins] +- Tree: Renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. (#600, #1330) +- MenuBar: Fixed minor rendering issues on the right size when resizing a window very small and using rounded window corners. +- MenuBar: better software clipping to handle small windows, in particular child window don't have minimum constraints so we need to render clipped menus better. +- BeginMenu(): Tweaked the Arrow/Triangle displayed on child menu items. +- Columns: Clipping columns borders on Y axis on CPU because some Linux GPU drivers appears to be unhappy with triangle spanning large regions. (#125) +- Columns: Added ImGuiColumnsFlags_GrowParentContentsSize to internal API to restore old content sizes behavior (may be obsolete). (#1444, #125) +- Columns: Columns width is no longer lost when dragging a column to the right side of the window, until releasing the mouse button you have a chance to save them. (#1499, #125). [@ggtucker] +- Columns: Fixed dragging when using a same of columns multiple times in the frame. (#125) +- Indent(), Unindent(): Allow passing negative values. +- ColorEdit4(): Made IsItemActive() return true when picker pop-up is active. (#1489) +- ColorEdit4(): Tweaked tooltip so that the color button aligns more correctly with text. +- ColorEdit4(): Support drag and drop. Color buttons can be used as drag sources, and ColorEdit widgets as drag targets. (#143) +- ColorPicker4(): Fixed continuously returning true when holding mouse button on the sat/value/alpha locations. We only return true on value change. (#1489) +- NewFrame(): using literal strings in the most-frequently firing IM_ASSERT expressions to increase the odd of programmers seeing them (especially those who don't use a debugger). +- NewFrame() now asserts if neither Render or EndFrame have been called. Exposed EndFrame(). Made it legal to call EndFrame() more than one. (#1423) +- ImGuiStorage: Added BuildSortByKey() helper to rebuild storage from scratch. +- ImFont: Added GetDebugName() helper. +- ImFontAtlas: Added missing Thai punctuation in the GetGlyphRangesThai() ranges. (#1396) [@nProtect] +- ImDrawList: Removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Anti-aliasing is controlled via the regular style.AntiAliased flags. +- ImDrawList: Added ImDrawList::AddImageRounded() helper. (#845) [@thedmd] +- ImDrawList: Refactored to make ImDrawList independent of ImGui. Removed static variable in PathArcToFast() which caused linking issues to some. +- ImDrawList: Exposed ImDrawCornerFlags, replaced occurrences of ~0 with an explicit ImDrawCornerFlags_All. NB: Inversed BotLeft (prev 1<<3, now 1<<2) and BotRight (prev 1<<2, now 1<<3). +- ImVector: Added ImVector::push_front() helper. +- ImVector: Added ImVector::contains() helper. +- ImVector: insert() uses grow_capacity() instead of using grow policy inconsistent with push_back(). +- Internals: Remove requirement to define IMGUI_DEFINE_PLACEMENT_NEW to use the IM_PLACEMENT_NEW macro. (#1103) +- Internals: ButtonBehavior: Fixed ImGuiButtonFlags_NoHoldingActiveID flag from incorrectly setting the ActiveIdClickOffset field. + This had no known effect within imgui code but could have affected custom drag and drop patterns. And it is more correct this way! (#1418) +- Internals: ButtonBehavior: Fixed ImGuiButtonFlags_AllowOverlapMode to avoid temporarily activating widgets on click before they have been correctly double-hovered. (#319, #600) +- Internals: Added SplitterBehavior() helper. (#319) +- Internals: Added IM_NEW(), IM_DELETE() helpers. (#484, #504, #1517) +- Internals: Basic refactor of the settings API which now allows external elements to be loaded/saved. +- Demo: Added ShowFontSelector() showing loaded fonts. +- Demo: Added ShowStyleSelector() to select among default styles. (#707) +- Demo: Renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). +- Demo: Style Editor: Added a "Simplified settings" sections with check-boxes for border size and frame rounding. (#707, #1019) +- Demo: Style Editor: Added combo box to select stock styles and select current font when multiple are loaded. (#707) +- Demo: Style Editor: Using local storage so Save/Revert button makes more sense without code passing its storage. Added horizontal scroll bar. Fixed Save/Revert button to be always accessible. (#1211) +- Demo: Console: Fixed context menu issue. (#1404) +- Demo: Console: Fixed incorrect positioning which was hidden by a minor scroll issue (this would affect people who copied the Console code as is). +- Demo: Constrained Resize: Added more test cases. (#1417) +- Demo: Custom Rendering: Fixed clipping rectangle extruding out of parent window. +- Demo: Layout: Removed unnecessary and misleading BeginChild/EndChild calls. +- Demo: The "Color Picker with Palette" demo supports drag and drop. (#143) +- Demo: Display better mouse cursor info for debugging backends. +- Demo: Stopped using rand() function in demo code. +- Examples: Added a handful of extra comments (about fonts, third-party libraries used in the examples, etc.). +- Examples: DirectX9: Handle loss of D3D9 device (D3DERR_DEVICELOST). (#1464) +- Examples: Added null_example/ which is helpful for quick testing on multiple compilers/settings without relying on graphics library. +- Fix for using alloca() in "Clang with Microsoft Codechain" mode. +- Various fixes, optimizations, comments. + + +----------------------------------------------------------------------- + VERSION 1.52 (2017-10-27) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.52 + +Breaking Changes: + +- IO: `io.MousePos` needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing, instead of ImVec2(-1,-1) as previously) This is needed so we can clear `io.MouseDelta` field when the mouse is made available again. +- Renamed `AlignFirstTextHeightToWidgets()` to `AlignTextToFramePadding()`. Kept inline redirection function (will obsolete). +- Obsoleted the legacy 5 parameters version of Begin(). Please avoid using it. If you need a transparent window background, uses `PushStyleColor()`. The old size parameter there was also misleading and equivalent to calling `SetNextWindowSize(size, ImGuiCond_FirstTimeEver)`. Kept inline redirection function (will obsolete). +- Obsoleted `IsItemHoveredRect()`, `IsMouseHoveringWindow()` in favor of using the newly introduced flags of `IsItemHovered()` and `IsWindowHovered()`. Kept inline redirection function (will obsolete). (#1382) +- Obsoleted 'SetNextWindowPosCenter()' in favor of using 1SetNextWindowPos()` with a pivot value which allows to do the same and more. Keep inline redirection function. +- Removed `IsItemRectHovered()`, `IsWindowRectHovered()` recently introduced in 1.51 which were merely the more consistent/correct names for the above functions which are now obsolete anyway. (#1382) +- Changed `IsWindowHovered()` default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it. (#1382) +- Renamed imconfig.h's `IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS`/`IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS` to `IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS`/`IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS` for consistency. +- Renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete). + +Other Changes: + +- ProgressBar: fixed rendering when straddling rounded area. (#1296) +- SliderFloat, DragFloat: Using scientific notation e.g. "%.1e" in the displayed format string doesn't mistakenly trigger rounding of the value. [@MomentsInGraphics] +- Combo, InputFloat, InputInt: Made the small button on the right side align properly with the equivalent colored button of ColorEdit4(). +- IO: Tweaked logic for `io.WantCaptureMouse` so it now outputs false when e.g. hovering over void while an InputText() is active. (#621) [@pdoane] +- IO: Fixed `io.WantTextInput` from mistakenly outputting true when an activated Drag or Slider was previously turned into an InputText(). (#1317) +- Misc: Added flags to `IsItemHovered()`, `IsWindowHovered()` to access advanced hovering-test behavior. Generally useful for pop-ups and drag and drop behaviors: (relates to ~#439, #1013, #143, #925) + - `ImGuiHoveredFlags_AllowWhenBlockedByPopup` + - `ImGuiHoveredFlags_AllowWhenBlockedByActiveItem` + - `ImGuiHoveredFlags_AllowWhenOverlapped` + - `ImGuiHoveredFlags_RectOnly` +- Input: Added `IsMousePosValid()` helper. +- Input: Added `GetKeyPressedAmount()` to easily measure press count when the repeat rate is faster than the frame rate. +- Input/Focus: Disabled TAB and Shift+TAB when CTRL key is held. +- CheckBox: Now rendering a tick mark instead of a full square. +- ColorEdit4: Added "Copy as..." option in context menu. (#346) +- ColorPicker: Improved ColorPicker hue wheel color interpolation. (#1313) [@thevaber] +- ColorButton: Reduced bordering artifact that would be particularly visible with an opaque Col_FrameBg and FrameRounding enabled. +- ColorButton: Fixed rendering color button with a checkerboard if the transparency comes from the global style.Alpha and not from the actual source color. +- TreeNode: Added `ImGuiTreeNodeFlags_FramePadding` flag to conveniently create a tree node with full padding at the beginning of a line, without having to call `AlignTextToFramePadding()`. +- Trees: Fixed calling `SetNextTreeNodeOpen()` on a collapsed window leaking to the first tree node item of the next frame. +- Layout: Horizontal layout is automatically enforced in a menu bar, so you can use non-MenuItem elements without calling SameLine(). +- Separator: Output a vertical separator when used inside a menu bar (or in general when horizontal layout is active, but that isn't exposed yet!). +- Window: Added `IsWindowAppearing()` helper (helpful e.g. as a condition before initializing some of your own things.). +- Window: Added pivot parameter to `SetNextWindowPos()`, making it possible to center or right align a window. Obsoleted `SetNextWindowPosCenter()`. +- Window: Fixed title bar color of top-most window under a modal window. +- Window: Fixed not being able to move a window by clicking on one of its child window. (#1337, #635) +- Window: Fixed `Begin()` auto-fit calculation code that predict the presence of a scrollbar so it works better when window size constraints are used. +- Window: Fixed calling `Begin()` more than once per frame setting `window_just_activated_by_user` which in turn would set enable the Appearing condition for that frame. +- Window: The implicit "Debug" window now uses a "Debug##Default" identifier instead of "Debug" to allow user creating a window called "Debug" without losing their custom flags. +- Window: Made the `ImGuiWindowFlags_NoMove` flag properly inherited from parent to child. In a setup with ParentWindow (no flag) -> Child (NoMove) -> SubChild (no flag), the user won't be able to move the parent window by clicking on SubChild. (#1381) +- Popups: Pop-ups can be closed with a right-click anywhere, without altering focus under the pop-up. (~#439) +- Popups: `BeginPopupContextItem()`, `BeginPopupContextWindow()` are now setup to allow reopening a context menu by right-clicking again. (~#439) +- Popups: `BeginPopupContextItem()` now supports a NULL string identifier and uses the last item ID if available. +- Popups: Added `OpenPopupOnItemClick()` helper which mimic `BeginPopupContextItem()` but doesn't do the BeginPopup(). +- MenuItem: Only activating on mouse release. [@Urmeli0815] (was already fixed in nav branch). +- MenuItem: Made tick mark thicker (thick mark?). +- MenuItem: Tweaks to be usable inside a menu bar (nb: it looks like a regular menu and thus is misleading, prefer using Button() and regular widgets in menu bar if you need to). (#1387) +- ImDrawList: Fixed a rare draw call merging bug which could lead to undisplayed triangles. (#1172, #1368) +- ImDrawList: Fixed a rare bug in `ChannelsMerge()` when all contents has been clipped, leading to an extraneous draw call being created. (#1172, #1368) +- ImFont: Added `AddGlyph()` building helper for use by custom atlas builders. +- ImFontAtlas: Added support for CustomRect API to submit custom rectangles to be packed into the atlas. You can map them as font glyphs, or use them for custom purposes. + After the atlas is built you can query the position of your rectangles in the texture and then copy your data there. You can use this features to create e.g. full color font-mapped icons. +- ImFontAtlas: Fixed fall-back handling when merging fonts, if a glyph was missing from the second font input it could have used a glyph from the first one. (#1349) [@inolen] +- ImFontAtlas: Fixed memory leak on build failure case when stbtt_InitFont failed (generally due to incorrect or supported font type). (#1391) (@Moka42) +- ImFontConfig: Added `RasterizerMultiply` option to alter the brightness of individual fonts at rasterization time, which may help increasing readability for some. +- ImFontConfig: Added `RasterizerFlags` to pass options to custom rasterizer (e.g. the [imgui_freetype](https://github.com/ocornut/imgui_club/tree/master/imgui_freetype) rasterizer in imgui_club has such options). +- ImVector: added resize() variant with initialization value. +- Misc: Changed the internal name formatting of child windows identifier to use slashes (instead of dots) as separator, more readable. +- Misc: Fixed compilation with `IMGUI_DISABLE_OBSOLETE_FUNCTIONS` defined. +- Misc: Marked all format+va_list functions with format attribute so GCC/Clang can warn about misuses. +- Misc: Fixed compilation on NetBSD due to missing alloca.h (#1319) [@RyuKojiro] +- Misc: Improved warnings compilation for newer versions of Clang. (#1324) (@waywardmonkeys) +- Misc: Added `io.WantMoveMouse flags` (from Nav branch) and honored in Examples applications. Currently unused but trying to spread Examples applications code that supports it. +- Misc: Added `IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS` support in imconfig.h to allow user reimplementing the `ImFormatString()` functions e.g. to use stb_printf(). (#1038) +- Misc: [Windows] Fixed default Win32 `SetClipboardText()` handler leaving the Win32 clipboard handler unclosed on failure. [@pdoane] +- Style: Added `ImGuiStyle::ScaleAllSizes(float)` helper to make it easier to have application transition e.g. from low to high DPI with a matching style. +- Metrics: Draw window bounding boxes when hovering Pos/Size; List all draw layers; Trimming empty commands like Render() does. +- Examples: OpenGL3: Save and restore sampler state. (#1145) [@nlguillemot] +- Examples: OpenGL2, OpenGL3: Save and restore polygon mode. (#1307) [@JJscott] +- Examples: DirectX11: Allow creating device with feature level 10 since we don't really need much for that example. (#1333) +- Examples: DirectX9/10/12: Using the Win32 SetCapture/ReleaseCapture API to read mouse coordinates when they are out of bounds. (#1375) [@Gargaj, @ocornut] +- Tools: Fixed binary_to_compressed_c tool to return 0 when successful. (#1350) [@benvanik] +- Internals: Exposed more helpers and unfinished features in imgui_internal.h. (use at your own risk!). +- Internals: A bunch of internal refactoring, hopefully haven't broken anything! Merged a bunch of internal changes from the upcoming Navigation branch. +- Various tweaks, fixes and documentation changes. + +Beta Navigation Branch: +(Lots of work has been done toward merging the Beta Gamepad/Keyboard Navigation branch (#787) in master.) +(Please note that this branch is always kept up to date with master. If you are using the navigation branch, some of the changes include:) +- Nav: Added `#define IMGUI_HAS_NAV` in imgui.h to ease sharing code between both branches. (#787) +- Nav: MainMenuBar now releases focus when user gets out of the menu layer. (#787) +- Nav: When applying focus to a window with only menus, the menu layer is automatically activated. (#787) +- Nav: Added `ImGuiNavInput_KeyMenu` (~Alt key) aside from ImGuiNavInput_PadMenu input as it is one differentiator of pad vs keyboard that was detrimental to the keyboard experience. Although isn't officially supported, it makes the current experience better. (#787) +- Nav: Move requests now wrap vertically inside Menus and Pop-ups. (#787) +- Nav: Allow to collapse tree nodes with NavLeft and open them with NavRight. (#787, #1079). +- Nav: It's now possible to navigate sibling of a menu-bar while navigating inside one of their child. If a Left<>Right navigation request fails to find a match we forward the request to the root menu. (#787, #126) +- Nav: Fixed `SetItemDefaultFocus` from stealing default focus when we are initializing default focus for a menu bar layer. (#787) +- Nav: Support for fall-back horizontal scrolling with PadLeft/PadRight (nb: fall-back scrolling is only used to navigate windows that have no interactive items). (#787) +- Nav: Fixed tool-tip from being selectable in the window selection list. (#787) +- Nav: `CollapsingHeader(bool*)` variant: fixed for `IsItemHovered()` not working properly in the nav branch. (#600, #787) +- Nav: InputText: Fixed using Up/Down history callback feature when Nav is enabled. (#787) +- Nav: InputTextMultiline: Fixed navigation/selection. Disabled selecting all when activating a multi-line text editor. (#787) +- Nav: More consistently drawing a (thin) navigation rectangle hover filled frames such as tree nodes, collapsing header, menus. (#787) +- Nav: Various internal refactoring. + + +----------------------------------------------------------------------- + VERSION 1.51 (2017-08-24) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.51 + +Breaking Changes: + +Work on dear imgui has been gradually resuming. It means that fixes and new features should be tackled at a faster rate than last year. However, in order to move forward with the library and get rid of some cruft, I have taken the liberty to be a little bit more aggressive than usual with API breaking changes. Read the details below and search for those names in your code! In the grand scheme of things, those changes are small and should not affect everyone, but this is technically our most aggressive release so far in term of API breakage. If you want to be extra forward-facing, you can enable `#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in your imconfig.h to disable the obsolete names/redirection. + +- Renamed `IsItemHoveredRect()` to `IsItemRectHovered()`. Kept inline redirection function (will obsolete). +- Renamed `IsMouseHoveringWindow()` to `IsWindowRectHovered()` for consistency. Kept inline redirection function (will obsolete). +- Renamed `IsMouseHoveringAnyWindow()` to `IsAnyWindowHovered()` for consistency. Kept inline redirection function (will obsolete). +- Renamed `ImGuiCol_Columns***` enums to `ImGuiCol_Separator***`. Kept redirection enums (will obsolete). +- Renamed `ImGuiSetCond***` types and enums to `ImGuiCond***`. Kept redirection enums (will obsolete). +- Renamed `GetStyleColName()` to `GetStyleColorName()` for consistency. Unlikely to be used by end-user! +- Added `PushStyleColor(ImGuiCol idx, ImU32 col)` overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicitly to fix. +- Marked the weird `IMGUI_ONCE_UPON_A_FRAME` helper macro as obsolete. Prefer using the more explicit `ImGuiOnceUponAFrame`. +- Changed `ColorEdit4(const char* label, float col[4], bool show_alpha = true)` signature to `ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)`, where flags 0x01 is a safe no-op (hello dodgy backward compatibility!). The new `ColorEdit4`/`ColorPicker4` functions have lots of available flags! Check and run the demo window, under "Color/Picker Widgets", to understand the various new options. +- Changed signature of `ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)` to `ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0,0))`. This function was rarely used and was very dodgy (no explicit ID!). +- Changed `BeginPopupContextWindow(bool also_over_items=true, const char* str_id=NULL, int mouse_button=1)` signature to `(const char* str_id=NULL, int mouse_button=1, bool also_over_items=true)`. This is perhaps the most aggressive change in this update, but note that the majority of users relied on default parameters completely, so this will affect only a fraction of users of this already rarely used function. +- Removed `IsPosHoveringAnyWindow()`, which was partly broken and misleading. In the vast majority of cases, people using that function wanted to use `io.WantCaptureMouse` flag. Replaced with IM_ASSERT + comment redirecting user to `io.WantCaptureMouse`. (#1237) +- Removed the old `ValueColor()` helpers, they are equivalent to calling `Text(label)` + `SameLine()` + `ColorButton()`. +- Removed `ColorEditMode()` and `ImGuiColorEditMode` type in favor of `ImGuiColorEditFlags` and parameters to the various Color*() functions. The `SetColorEditOptions()` function allows to initialize default but the user can still change them with right-click context menu. Commenting out your old call to `ColorEditMode()` may just be fine! + +Other Changes: + +- Added flags to `ColorEdit3()`, `ColorEdit4()`. The color edit widget now has a context-menu and access to the color picker. (#346) +- Added flags to `ColorButton()`. (#346) +- Added `ColorPicker3()`, `ColorPicker4()`. The API along with those of the updated `ColorEdit4()` was designed so you may use them in various situation and hopefully compose your own picker if required. There are a bunch of available flags, check the Demo window and comment for `ImGuiColorEditFlags_`. Some of the options it supports are: two color picker types (hue bar + sat/val rectangle, hue wheel + rotating sat/val triangle), display as u8 or float, lifting 0.0..1.0 constraints (currently rgba only), context menus, alpha bar, background checkerboard options, preview tooltip, basic revert. For simple use, calling the existing `ColorEdit4()` function as you did before will be enough, as you can now open the color picker from there. (#346) [@r-lyeh, @nem0, @thennequin, @dariomanesku and @ocornut] +- Added `SetColorEditOptions()` to set default color options (e.g. if you want HSV over RGBA, float over u8, select a default picker mode etc. at startup time without a user intervention. Note that the user can still change options with the context menu unless disabled with `ImGuiColorFlags_NoOptions` or explicitly enforcing a display type/picker mode etc.). +- Added user-facing `IsPopupOpen()` function. (#891) [@mkeeter] +- Added `GetColorU32(u32)` variant that perform the style alpha multiply without a floating-point round trip, and helps makes code more consistent when using ImDrawList APIs. +- Added `PushStyleColor(ImGuiCol idx, ImU32 col)` overload. +- Added `GetStyleColorVec4(ImGuiCol idx)` which is equivalent to accessing `ImGui::GetStyle().Colors[idx]` (aka return the raw style color without alpha alteration). +- ImFontAtlas: Added `GlyphRangesBuilder` helper class, which makes it easier to build custom glyph ranges from your app/game localization data, or add into existing glyph ranges. +- ImFontAtlas: Added `TexGlyphPadding` option. (#1282) [@jadwallis] +- ImFontAtlas: Made it possible to override size of AddFontDefault() (even if it isn't really recommended!). +- ImDrawList: Added `GetClipRectMin()`, `GetClipRectMax()` helpers. +- Fixed Ini saving crash if the ImGuiWindowFlags_NoSavedSettings gets removed from a window after its creation (unlikely!). (#1000) +- Fixed `PushID()`/`PopID()` from marking parent window as Accessed (which needlessly woke up the root "Debug" window when used outside of a regular window). (#747) +- Fixed an assert when calling `CloseCurrentPopup()` twice in a row. [@nem0] +- Window size can be loaded from .ini data even if ImGuiWindowFlags_NoResize flag is set. (#1048, #1056) +- Columns: Added `SetColumnWidth()`. (#913) [@ggtucker] +- Columns: Dragging a column preserve its width by default. (#913) [@ggtucker] +- Columns: Fixed first column appearing wider than others. (#1266) +- Columns: Fixed allocating space on the right-most side with the assumption of a vertical scrollbar. The space is only allocated when needed. (#125, #913, #893, #1138) +- Columns: Fixed the right-most column from registering its content width to the parent window, which led to various issues when using auto-resizing window or e.g. horizontal scrolling. (#519, #125, #913) +- Columns: Refactored some of the columns code internally toward a better API (not yet exposed) + minor optimizations. (#913) [@ggtucker, @ocornut] +- Popups: Most pop-ups windows can be moved by the user after appearing (if they don't have explicit positions provided by caller, or e.g. sub-menu pop-up). The previous restriction was totally arbitrary. (#1252) +- Tooltip: `SetTooltip()` is expanded immediately into a window, honoring current font / styling setting. Add internal mechanism to override tooltips. (#862) +- PlotHistogram: bars are drawn based on zero-line, so negative values are going under. (#828) +- Scrolling: Fixed return values of `GetScrollMaxX()`, `GetScrollMaxY()` when both scrollbars were enabled. Tweak demo to display more data. (#1271) [@degracode] +- Scrolling: Fixes for Vertical Scrollbar not automatically getting enabled if enabled Horizontal Scrollbar straddle the vertical limit. (#1271, #246) +- Scrolling: `SetScrollHere()`, `SetScrollFromPosY()`: Fixed Y scroll aiming when Horizontal Scrollbar is enabled. (#665). +- [Windows] Clipboard: Fixed not closing Win32 clipboard on early open failure path. (#1264) +- Removed an unnecessary dependency on int64_t which failed on some older compilers. +- Demo: Rearranged everything under Widgets in a more consistent way. +- Demo: Columns: Added Horizontal Scrolling demo. Tweaked another Columns demo. (#519, #125, #913) +- Examples: OpenGL: Various makefiles for MINGW, Linux. (#1209, #1229, #1209) [@fr500, @acda] +- Examples: Enabled vsync by default in example applications, so it doesn't confuse people that the sample run at 2000+ fps and waste an entire CPU. (#1213, #1151). +- Various other small fixes, tweaks, comments, optimizations. + + +----------------------------------------------------------------------- + VERSION 1.50 (2017-06-02) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.50 + +Breaking Changes: + +- Added a void* user_data parameter to Clipboard function handlers. (#875) +- SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully breakage should be minimal. +- Renamed ImDrawList::PathFill() - rarely used directly - to ImDrawList::PathFillConvex() for clarity and consistency. +- Removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset. +- Style: style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc. +- BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetId() and use it instead of passing string to BeginChild(). + +Other Changes: + +- InputText(): Added support for CTRL+Backspace (delete word). +- InputText(): OSX uses Super+Arrows for home/end. Add Shortcut+Backspace support. (#650) [@michaelbartnett] +- InputText(): Got rid of individual OSX-specific options in ImGuiIO, added a single io.OSXBehaviors flag. (#473, #650) +- InputText(): Fixed pressing home key on last character when it isn't a trailing \n (#588, #815) +- InputText(): Fixed state corruption/crash bug in stb_textedit.h redo logic when exhausting undo/redo char buffer. (#715. #681) +- InputTextMultiline(): Fixed CTRL+DownArrow moving scrolling out of bounds. +- InputTextMultiline(): Scrollbar fix for when input and latched internal buffers differs in a way that affects vertical scrollbar existence. (#725) +- ImFormatString(): Fixed an overflow handling bug with implementation of vsnprintf() that do not return -1. (#793) +- BeginChild(const char*) now applies stack id to provided label, consistent with other widgets. (#894, #713) +- SameLine() with explicit X position is relative to left of group/columns. (ref #746, #125, #630) +- SliderInt(), SliderFloat() supports reverse direction (where v_min > v_max). (#854) +- SliderInt(), SliderFloat() better support for when v_min==v_max. (#919) +- SliderInt(), SliderFloat() enforces writing back value when interacting, to be consistent with other widgets. (#919) +- SliderInt, SliderFloat(): Fixed edge case where style.GrabMinSize being bigger than slider width can lead to a division by zero. (#919) +- Added IsRectVisible() variation with explicit start-end positions. (#768) [@thedmd] +- Fixed TextUnformatted() clipping bug in the large-text path when horizontal scroll has been applied. (#692, #246) +- Fixed minor text clipping issue in window title when using font straying above usual line. (#699) +- Fixed SetCursorScreenPos() fixed not adjusting CursorMaxPos as well. +- Fixed scrolling offset when using SetScrollY(), SetScrollFromPosY(), SetScrollHere() with menu bar. +- Fixed using IsItemActive() after EndGroup() or any widget using groups. (#840, #479) +- Fixed IsItemActive() lagging by one frame on initial widget activation. (#840) +- Fixed Separator() zero-height bounding box resulting in clipping when laying exactly on top line of clipping rectangle (#860) +- Fixed PlotLines() PlotHistogram() calling with values_count == 0. +- Fixed clicking on a window's void while staying still overzealously marking .ini settings as dirty. (#923) +- Fixed assert triggering when a window has zero rendering but has a callback. (#810) +- Scrollbar: Fixed rendering when sizes are negative to reduce glitches (which can happen with certain style settings and zero WindowMinSize). +- EndGroup(): Made IsItemHovered() work when an item was activated within the group. (#849) +- BulletText(): Fixed stopping to display formatted string after the '##' mark. +- Closing the focused window restore focus to the first active root window in descending z-order .(part of #727) +- Word-wrapping: Fixed a bug where we never wrapped after a 1 character word. [@sronsse] +- Word-wrapping: Fixed TextWrapped() overriding wrap position if one is already set. (#690) +- Word-wrapping: Fixed incorrect testing for negative wrap coordinates, they are perfectly legal. (#706) +- ImGuiListClipper: Fixed automatic-height calc path dumbly having user display element 0 twice. (#661, #716) +- ImGuiListClipper: Fix to behave within column. (#661, #662, #716) +- ImDrawList: Renamed ImDrawList::PathFill() to ImDrawList::PathFillConvex() for clarity. (BREAKING API) +- Columns: End() avoid calling Columns(1) if no columns set is open, not sure why it wasn't the case already (pros: faster, cons: exercise less code). +- ColorButton(): Fix ColorButton showing wrong hex value for alpha. (#1068) [@codecat] +- ColorEdit4(): better preserve inputting value out of 0..255 range, display then clamped in Hexadecimal form. +- Shutdown() clear out some remaining pointers for sanity. (#836) +- Added IMGUI_USE_BGRA_PACKED_COLOR option in imconfig.h (#767, #844) [@thedmd] +- Style: Removed the inconsistent shadow under RenderCollapseTriangle() (~#707) +- Style: Added ButtonTextAlign, ImGuiStyleVar_ButtonTextAlign. (#842) +- ImFont: Allowing to use up to 0xFFFE glyphs in same font (increased from previous 0x8000). +- ImFont: Added GetGlyphRangesThai() helper. [@nProtect] +- ImFont: CalcWordWrapPositionA() fixed font scaling with fallback character. +- ImFont: Calculate and store the approximate texture surface to get an idea of how costly each source font is. +- ImFontConfig: Added GlyphOffset to explicitly offset glyphs at font build time, useful for merged fonts. Removed MergeGlyphCenterV. (BREAKING API) +- Clarified asserts in CheckStacksSize() when there is a stack mismatch. +- Context: Support for #define-ing GImGui and IMGUI_SET_CURRENT_CONTEXT_FUNC to enable custom thread-based hackery (#586) +- Updated stb_truetype.h to 1.14 (added OTF support, removed warnings). (#883, #976) +- Updated stb_rect_pack.h to 0.10 (removed warnings). (#883) +- Added ImGuiMouseCursor_None enum value for convenient usage by app/backends. +- Clipboard: Added a void* user_data parameter to Clipboard function handlers. (#875) (BREAKING API) +- Internals: Refactor internal text alignment options to use ImVec2, removed ImGuiAlign. (#842, #222) +- Internals: Renamed ImLoadFileToMemory to ImFileLoadToMemory to be consistent with ImFileOpen + fix mismatching .h name. (#917) +- OS/Windows: Fixed Windows default clipboard handler leaving its buffer unfreed on application's exit. (#714) +- OS/Windows: No default IME handler when compiling for Windows using GCC. (#738) +- OS/Windows: Now using _wfopen() instead of fopen() to allow passing in paths/filenames with UTF-8 characters. (#917) +- Tools: binary_to_compressed_c: Avoid ?? trigraphs sequences in string outputs which break some older compilers. (#839) +- Demo: Added an extra 3-way columns demo. +- Demo: ShowStyleEditor: show font character map / grid in more details. +- Demo: Console: Fixed a completion bug when multiple candidates are equals and match until the end. +- Demo: Fixed 1-byte off overflow in the ShowStyleEditor() combo usage. (#783) [@bear24rw] +- Examples: Accessing ImVector fields directly, feel less stl-ey. (#810) +- Examples: OpenGL*: Saving/restoring existing scissor rectangle for completeness. (#807) +- Examples: OpenGL*: Saving/restoring active texture number (the value modified by glActiveTexture). (#1087, #1088, #1116) +- Examples: OpenGL*: Saving/restoring separate color/alpha blend functions correctly. (#1120) [@greggman] +- Examples: OpenGL2: Uploading font texture as RGBA32 to increase compatibility with users shaders for beginners. (#824) +- Examples: Vulkan: Countless fixes and improvements. (#785, #804, #910, #1017, #1039, #1041, #1042, #1043, #1080) [@martty, @Loftilus, @ParticlePeter, @SaschaWillems] +- Examples: DirectX9/10/10: Only call SetCursor(NULL) is io.MouseDrawCursor is set.

Now using `CreateContext()`, `DestroyContext()`, `GetCurrentContext()`, `SetCurrentContext()`. If you were using multiple contexts the change should be obvious and trivial. +- Obsoleted old signature of `CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false)`, as extra parameters were badly designed and rarely used. Most uses were using 1 parameter and shouldn't affect you. You can replace the "default_open = true" flag in new API with `CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen)`. +- Changed `ImDrawList::PushClipRect(ImVec4 rect)` to `ImDraw::PushClipRect(ImVec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false)`. Note that higher-level `ImGui::PushClipRect()` is preferable because it will clip at logic/widget level, whereas `ImDrawList::PushClipRect()` only affect your renderer. +- Title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore (see #655). If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you. However if your TitleBg/TitleBgActive alpha was <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar. + This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color. (Or If this is confusing, just pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color.) + + ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) + { + float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)); + float k = title_bg_col.w / new_a; + return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); + } + +Other changes: + +- New version of ImGuiListClipper helper calculates item height automatically.

(#581, #324) +- Added CreateContext()/DestroyContext()/GetCurrentContext()/SetCurrentContext(). Obsoleted nearly identical GetInternalState()/SetInternalState() functions. (#586, #269) +- Added NewLine() to undo a SameLine() and as a shy reminder that horizontal layout support hasn't been implemented yet. +- Added IsItemClicked() helper. (#581) +- Added CollapsingHeader() variant with close button. (#600) +- Fixed MenuBar missing lower border when borders are enabled. +- InputText(): Fixed clipping of cursor rendering in case it gets out of the box (which can be forced w/ ImGuiInputTextFlags_NoHorizontalScroll. (#601) +- Style: Changed default IndentSpacing from 22 to 21. (#581, #324) +- Style: Fixed TitleBg/TitleBgActive color being rendered above WindowBg color, which was inconsistent and causing visual artifact. (#655) + This broke the meaning of TitleBg and TitleBgActive. Only affect values where Alpha<1.0f. Fixed default theme. Read comments in "API BREAKING CHANGES" section to convert. +- Relative rendering of order of Child windows creation is preserved, to allow more control with overlapping children. (#595) +- Fixed GetWindowContentRegionMax() being off by ScrollbarSize amount when explicit SizeContents is set. +- Indent(), Unindent(): optional non-default indenting width. (#324, #581) +- Bullet(), BulletText(): Slightly bigger. Less polygons. +- ButtonBehavior(): fixed subtle old bug when a repeating button would also return true on mouse release (barely noticeable unless RepeatRate is set to be very slow). (#656) +- BeginMenu(): a menu that becomes disabled while open gets closed down, facilitate user's code. (#126) +- BeginGroup(): fixed using within Columns set. (#630) +- Fixed a lag in reading the currently hovered window when dragging a window. (#635) +- Obsoleted 4 parameters version of CollapsingHeader(). Refactored code into TreeNodeBehavior. (#600, #579) +- Scrollbar: minor fix for top-right rounding of scrollbar background when window has menu bar but no title bar. +- MenuItem(): the check mark renders in disabled color when menu item is disabled. +- Fixed clipping rectangle floating point representation to ensure renderer-side float point operations yield correct results in typical DirectX/GL settings. (#582, 597) +- Fixed GetFrontMostModalRootWindow(), fixing missing fade-out when a combo pop was used stacked over a modal window. (#604) +- ImDrawList: Added AddQuad(), AddQuadFilled() helpers. +- ImDrawList: AddText() refactor, moving some code to ImFont, reserving less unused vertices when large vertical clipping occurs. +- ImFont: Added RenderChar() helper. +- ImFont: Added AddRemapChar() helper. (#609) +- ImFontConfig: Clarified persistence requirement of GlyphRanges array.

Some hand-tuned layout may be affected slightly. (#346) +- Style: removed `style.WindowFillAlphaDefault` which was confusing and redundant, baked alpha into `ImGuiCol_WindowBg` color. If you had a custom WindowBg color but didn't change WindowFillAlphaDefault, multiply WindowBg alpha component by 0.7. Renamed `ImGuiCol_TooltipBg` to `ImGuiCol_PopupBG`, applies to other types of pop-ups. `bg_alpha` parameter of 5-parameters version of Begin() is an override. (#337) +- InputText(): Added BufTextLen field in ImGuiTextEditCallbackData. Requesting user to update it if the buffer is modified in the callback. Added a temporary length-check assert to minimize panic for the 3 people using the callback. (#541) +- Renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize().

(@zapolnov) (#516) +- Begin(): made the close button explicitly set the boolean to false instead of toggling it. (#499) +- BeginChild()/EndChild(): fixed incorrect layout to allow widgets submitted after an auto-fitted child window.

(#462, #503) +- Fixed Image(), ImageButtion() rendering a rectangle 1 px too large on each axis. (#457) +- SetItemAllowOverlap(): Promoted from imgui_internal.h to public imgui.h api. (#517) +- Combo(): Right-most button stays highlighted when pop-up is open. +- Combo(): Display pop-up above if there's isn't enough space below / or select largest side. (#505) +- DragFloat(), SliderFloat(), InputFloat(): fixed cases of erroneously returning true repeatedly after a text input modification (e.g. "0.0" --> "0.000" would keep returning true). (#564) +- DragFloat(): Always apply value when mouse is held/widget active, so that an always-resetting variable (e.g. non saved local) can be passed. +- InputText(): OS X friendly behaviors: Word movement uses ALT key; Shortcuts uses CMD key; Double-clicking text select a single word; Jumping to next word sets cursor to end of current word instead of beginning of current word. (@zhiayang), (#473) +- InputText(): Added BufTextLen in ImGuiTextEditCallbackData. Requesting user to maintain it if buffer is modified. Zero-ing structure properly before use. (#541) +- CheckboxFlags(): Added support for testing/setting multiple flags at the same time. (@DMartinek) (#555) +- TreeNode(), CollapsingHeader() fixed not being able to use "##" sequence in a formatted label. +- ColorEdit4(): Empty label doesn't add InnerSpacing.x, matching behavior of other widgets. (#346) +- ColorEdit4(): Removed unnecessary calls to scanf() when idle in hexadecimal edit mode. +- BeginPopupContextItem(), BeginPopupContextWindow(): added early out optimization. +- CaptureKeyboardFromApp() / CaptureMouseFromApp(): added argument to allow clearing the capture flag. (#533) +- ImDrawList: Fixed index-overflow check broken by AddText() casting current index back to ImDrawIdx. (#514) +- ImDrawList: Fixed incorrect removal of trailing draw command if it is a callback command. +- ImDrawList: Allow windows with only a callback only to be functional. (#524) +- ImDrawList: Fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. (#457) +- ImDrawList: Fixed ImDrawList::AddCircle() to fit precisely within bounding box like AddCircleFilled() and AddRectFilled(). (#457) +- ImDrawList: AddCircle(), AddRect() takes optional thickness parameter. +- ImDrawList: Added AddTriangle(). +- ImDrawList: Added PrimQuadUV() helper to ease custom rendering of textured quads (require primitive reserve). +- ImDrawList: Allow AddText(ImFont\* font, float font_size, ...) variant to take NULL/0.0f as default. +- ImFontAtlas: heuristic increase default texture width up for large number of glyphs. (#491) +- ImTextBuffer: Fixed empty() helper which was utterly broken. +- Metrics: allow to inspect individual triangles in draw calls. +- Demo: added more draw primitives in the Custom Rendering example. (#457) +- Demo: extra comments and example for PushItemWidth(-1) patterns. +- Demo: InputText password demo filters out blanks.

(#396, #303) +- Fixed int>void\* warnings for 64-bit architectures with fancy warnings enabled. +- Renamed the dubious Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete. +- InputText(): Fixed and better handling of using keyboard while mouse button if being held and dragging. (#429) +- InputText(): Replace OS IME (Input Method Editor) cursor on top-left when we are not text editing. +- TreeNode(), CollapsingHeader(), Bullet(), BulletText(): various sizing and layout fixes to better support laying out + multiple item with different height on same line.

(#360) +- InputFloat() fixed explicit precision modifier, both display and input were broken. +- PlotHistogram(): improved rendering of histogram with a lot of values. +- Dummy(): creates an item so functions such as IsItemHovered() can be used. +- BeginChildFrame() helper: added the extra_flags parameter. +- Scrollbar: fixed rounding of background + child window consistenly have ChildWindowBg color under ScrollbarBg fill. (#355). +- Scrollbar: background color less translucent in default style so it works better when changing background color. +- Scrollbar: fixed minor rendering offset when borders are enabled. (#365) +- ImDrawList: fixed 1 leak per ImDrawList using the ChannelsSplit() API (via Columns).

They were incorrectly not incorporating this amount previously. + It PROBABLY shouldn't break anything, but that depends on how you used them. Namely: + - If you always used SetCursorPos() with values relative to GetCursorPos() there shouldn't be a problem. + However if you used absolute coordinates, note that SetCursorPosY(100.0f) will put you at +100 from the initial Y position (which may be scrolled out of the view), NOT at +100 from the window top border. Since there wasn't any official scrolling value on X axis (past just manually moving the cursor) this can only affect you if you used to set absolute coordinates on the Y axis which is hopefully rare/unlikely, and trivial to fix. + - The value of GetWindowContentRegionMax() isn't necessarily close to GetWindowWidth() if horizontally scrolling. + Previously they were roughly interchangeable (roughly because the content region exclude window padding). + +Other Changes: + +- Added Horizontal Scrollbar via ImGuiWindowFlags_HorizontalScroll (#246). +- Added GetScrollX(), GetScrollX(), GetScrollMaxX() apis (#246). +- Added SetNextWindowContentSize(), SetNextWindowContentWidth() to explicitly set the content size of a window, which + define the range of scrollbar. When set explicitly it also define the base value from which widget width are derived. +- Added IO.WantTextInput telling when ImGui is expecting text input, so that e.g. OS on-screen keyboard can be enabled. +- Added printf attribute to printf-like text formatting functions (Clang/GCC). +- Added GetMousePosOnOpeningCurrentPopup() helper. +- Added GetContentRegionAvailWidth() helper. +- Malformed UTF-8 data don't terminate string, output 0xFFFD instead (#307). +- ImDrawList: Added AddBezierCurve(), PathBezierCurveTo() API for cubic bezier curves (#311). +- ImDrawList: Allow to override ImDrawIdx type (#292). +- ImDrawList: Added an assert on overflowing index value (#292). +- ImDrawList: Fixed issues with channels split/merge.

(#287). +- Fixed Bullet() inconsistent layout behaviour when clipped. +- Fixed IsWindowHovered() not taking account of window hoverability (may be disabled because of a popup). +- Fixed InvisibleButton() not honoring negative size consistently with other widgets that do so. +- Fixed OpenPopup() accessing current window, effectively opening "Debug" when called from an empty window stack. +- TreeNode(): Fixed IsItemHovered() result being inconsistent with interaction visuals (#282). +- TreeNode(): Fixed mouse interaction padding past the node label being accounted for in layout (#282). +- BeginChild(): Passing a ImGuiWindowFlags_NoMove inhibits moving parent window from this child. +- BeginChild() fixed missing rounding for child sizes which leaked into layout and have items misaligned. +- Begin(): Removed default name = "Debug" parameter. We already have a "Debug" window pushed to the stack in the first place so it's not really a useful default. +- Begin(): Minor fixes with windows main clipping rectangle (e.g. child window with border). +- Begin(): Window flags are only read on the first call of the frame. Subsequent calls ignore flags, which allows appending to a window without worryin about flags. +- InputText(): ignore character input when ctrl/alt are held.

For each command, render ElemCount/3 triangles + using indices from the index buffer. +- If you are using a vanilla copy of one of the imgui_impl_XXXX.cpp provided in the example, you just need to update + your copy and you can ignore the rest. +- The signature of the io.RenderDrawListsFn handler has changed + From: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count) + To: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data) + With: argument 'cmd_lists' -> 'draw_data->CmdLists' + argument 'cmd_lists_count' -> 'draw_data->CmdListsCount' + ImDrawList 'commands' -> 'CmdBuffer' + ImDrawList 'vtx_buffer' -> 'VtxBuffer' + ImDrawList n/a -> 'IdxBuffer' (new) + ImDrawCmd 'vtx_count' -> 'ElemCount' + ImDrawCmd 'clip_rect' -> 'ClipRect' + ImDrawCmd 'user_callback' -> 'UserCallback' + ImDrawCmd 'texture_id' -> 'TextureId' +- If you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index + the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering! + Refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. Please upgrade! + +Other Changes: + +- Added anti-aliasing on lines and shapes based on primitives by @MikkoMononen (#133). + Between the use of indexed-rendering and the fact that the entire rendering codebase has been optimized and massaged + enough, with anti-aliasing enabled ImGui 1.43 is now running FASTER than 1.41. + Made some extra effort in making the code run faster in your typical Debug build. +- Anti-aliasing can be disabled in the ImGuiStyle structure via the AntiAliasedLines/AntiAliasedShapes fields for further gains. +- ImDrawList: Added AddPolyline(), AddConvexPolyFilled() with optional anti-aliasing. +- ImDrawList: Added stateful path building and stroking API. PathLineTo(), PathArcTo(), PathRect(), PathFill(), PathStroke() + with optional anti-aliasing. +- ImDrawList: Added AddRectFilledMultiColor() helper. +- ImDrawList: Added multi-channel rendering so out of order elements can be rendered in separate channels and then merged + back together (used by columns). +- ImDrawList: Fixed merging draw commands when equal clip rectangles are in the two first commands. +- ImDrawList: Fixed window draw lists not destructed properly on Shutdown(). +- ImDrawData: Added DeIndexAllBuffers() helper. +- Added lots of new font options ImFontAtlas::AddFont() and the new ImFontConfig structure. + - Added support for oversampling (ImFontConfig: OversampleH, OversampleV) and sub-pixel positioning (ImFontConfig: PixelSnapH). + Oversampling allows sub-pixel positioning but can also be used as a way to get some leeway with scaling fonts without re-rasterizing. + - Added GlyphExtraSpacing option to add extra horizontal spacing between characters (#242). + - Added MergeMode option to merge glyphs from different font inputs into a same font (#182, #232). + - Added FontDataOwnedByAtlas option to keep ownership from the TTF data buffer and request the atlas to make a copy (#220). +- Updated to stb_truetype 1.06 (+ minor mods) with better font rasterization. +- InputText: Added ImGuiInputTextFlags_NoHorizontalScroll flag. +- InputText: Added ImGuiInputTextFlags_AlwaysInsertMode flag. +- InputText: Added HasSelection() helper in ImGuiTextEditCallbackData as a clarification. +- InputText: Fix for using END key on a multi-line text editor (#275) +- Columns: Dispatch render of each column in a sub-draw list and merge on closure, saving a lot of draw calls! (#125) +- Popups: Fixed Combo boxes inside menus. (#272) +- Style: Added GrabRounding setting to make the sliders etc. grabs rounded. +- Changed SameLine() parameters from int to float. +- Fixed incorrect assert triggering when code stole ActiveID from user moving a window by calling e.g. SetKeyboardFocusHere(). +- Fixed CollapsingHeader() label rendering outside its frame in columns context where ClipRect max isn't aligned with the + right-side of the header. +- Metrics window: calculate bounding box of actual vertices when hovering a draw list. +- Examples: Showing more information in the Fonts section. +- Examples: Added a gratuitous About window. +- Examples: Updated all examples code (OpenGL/DX9/DX11/SDL/Allegro/iOS) to use indexed rendering. +- Examples: Fixed the SDL2 example to support Unicode text input (#274). + + +----------------------------------------------------------------------- + VERSION 1.42 (2015-07-08) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.42 + +Breaking Changes: + +- Renamed SetScrollPosHere() to SetScrollHere(). Kept inline redirection function (will obsolete). +- Renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion and make scrolling API consistent, + because positions (e.g. cursor position) are not equivalent to scrolling amount. +- Removed obsolete GetDefaultFontData() function that would assert anyway. + If you are updating from <1.30 you'll get a compile error instead of an assertion. (obsoleted 2015/01/11) + +Other Changes: + +- Added SDL2 example application (courtesy of @CedricGuillemet) +- Added iOS example application (courtesy of @joeld42) +- Added Allegro 5 example application (courtesy of @bggd) +- Added TitleBgActive color in style so focused window is made visible. (#253) +- Added CaptureKeyboardFromApp() / CaptureMouseFromApp() to manually enforce inputs capturing. +- Added DragFloatRange2() DragIntRange2() helpers. (#76) +- Added a Y centering ratio to SetScrollFromCursorPos() which can be used to aim the top or bottom of the window. (#150) +- Added SetScrollY(), SetScrollFromPos(), GetCursorStartPos() for manual scrolling manipulations. (#150). +- Added GetKeyIndex() helper for converting from ImGuiKey_\* enum to user's keycodes. Basically pulls from io.KeysMap[]. +- Added missing ImGuiKey_PageUp, ImGuiKey_PageDown so more UI code can be written without referring to implementation-side keycodes. +- MenuItem() can be activated on release. (#245) +- Allowing NewFrame() with DeltaTime==0.0f to not assert. +- Fixed IsMouseDragging(). (#260) +- Fixed PlotLines(), PlotHistogram() using incorrect hovering test so they would show their tooltip even when there is + a popup between mouse and the graph. +- Fixed window padding being reported incorrectly for child windows with borders when parent have no borders. +- Fixed a bug with TextUnformatted() clipping of long text blob when clipping y1 line sits on the first line of text. (#257) +- Fixed text baseline alignment of small button (no padding) after regular buttons. +- Fixed ListBoxHeader() not honoring negative sizes the same way as BeginChild() or BeginChildFrame(). (#263) +- Fixed warnings for more pedantic compiler settings (#258). +- ImVector<> cannot be re-defined anymore, cannot be replaced with std::vector<>. Allowed us to clean up and optimize + lots of code. Yeah! (#262) +- ImDrawList: store pointer to their owner name for easier auditing/debugging. +- Examples: added scroll tracking example with SetScrollFromCursorPos(). +- Examples: metrics windows render clip rectangle when hovering over a draw call. +- Lots of small optimization (particularly to run faster on unoptimized builds) and tidying up. +- Added font links in extra_fonts/ + instructions for using compressed fonts in C array. + + +----------------------------------------------------------------------- + VERSION 1.41 (2015-06-26) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.41 + +Breaking Changes: + +- Changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent). + Only makes a difference when texture have transparency. +- Changed Selectable() API from (label, selected, size) to (label, selected, flags, size). + Size override should be used very rarely so hopefully it doesn't affect many people. Sorry! + +Other Changes: + +- Added InputTextMultiline() multi-line text editor, vertical scrolling, selection, optimized enough to handle rather + big chunks of text in stateless context (thousands of lines are ok), option for allowing Tab to be input, option + for validating with Return or Ctrl+Return (#200). +- Added modal window API, BeginPopupModal(), follows the popup api scheme. Modal windows can be closed by clicking + outside. By default the rest of the screen is dimmed (using ImGuiCol_ModalWindowDarkening). Modal windows can be stacked. +- Added GetGlyphRangesCyrillic() helper (#237). +- Added SetNextWindowPosCenter() to center a window prior to knowing its size. (#249) +- Added IsWindowHovered() helper. +- Added IsMouseReleased(), IsKeyReleased() helpers to allow to user to avoid tracking them. (#248) +- Allow Set*WindowSize() calls to be used with popups. +- Window: AutoFit can be triggered on each axis separately via SetNextWindowSize(), etc. +- Window: fixed scrolling with mouse wheel while window was collapsed. +- Window: fixed mouse wheel scroll issues. +- DragFloat(), SliderFloat(): Fixed rounding of negative numbers which sometime made the negative lower bound unreachable. +- InputText(): lifted character count limit. +- InputText(): fixes in case of using per-window font scaling. +- Selectable(), MenuItem(): do not use frame rounding for hovering/selection. +- Selectable(): Added flag ImGuiSelectableFlags_DontClosePopups. +- Selectable(): Added flag ImGuiSelectableFlags_SpanAllColumns (#125). +- Combo(): Fixed issue with activating a Combo() not taking active id (#241). +- ColorButton(), ColorEdit4(): fix to ensure that the colored square stays square when non-default padding settings are used. +- BeginChildFrame(): returns bool like BeginChild() for clipping. +- SetScrollPosHere(): takes account of item height + more accurate centering + fixed precision issue. +- ImFont: ignoring '\r'. +- ImFont: added GetCharAdvance() helper. Exposed font Ascent and font Descent. +- ImFont: additional rendering optimizations. +- Metrics windows display storage size. + + +----------------------------------------------------------------------- + VERSION 1.40 (2015-05-31) +----------------------------------------------------------------------- + +Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.40 + +Breaking Changes: + +- The BeginPopup() API (introduced in 1.37) had to be changed to allow for stacked popups and menus. + Use OpenPopup() to toggle the opened state and BeginPopup() to append.** +- The third parameter of Button(), 'repeat_if_held' has been removed. While it's been very rarely used, + some code will possibly break if you didn't rely on the default parameter. + Use PushButtonRepeat()/PopButtonRepeat() to configure repeat. +- Renamed IsRectClipped() to !IsRectVisible() for consistency (opposite return value!). Kept inline redirection function (will obsolete) +- Renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline indirection function (will obsolete). + +Other Changes: + +- Menus: Added a menu system! Menus are typically populated with menu items and sub-menus, but you can add any sort of + widgets in them (buttons, text inputs, sliders, etc.). (#126) +- Menus: Added MenuItem() to append a menu item. Optional shortcut display, acts a button & toggle with checked/unchecked state, + disabled mode. Menu items can be used in any window. +- Menus: Added BeginMenu() to append a sub-menu. Note that you generally want to add sub-menu inside a popup or a menu-bar. + They will work inside a normal window but it will be a bit unusual. +- Menus: Added BeginMenuBar() to append to window menu-bar (set ImGuiWindowFlags_MenuBar to enable). +- Menus: Added BeginMainMenuBar() helper to append to a fullscreen main menu-bar. +- Popups: Support for stacked popups. Each popup level inhibit inputs to lower levels. The menus system is based on this. (#126). +- Popups: Added BeginPopupContextItem(), BeginPopupContextWindow(), BeginPopupContextVoid() to create a popup window on mouse-click. +- Popups: Popups have borders by default (#197), attenuated border alpha in default theme. +- Popups & Tooltip: Fit within display. Handling various positioning/sizing/scrolling edge cases. Better hysteresis when moving + in corners. Tooltip always tries to stay away from mouse-cursor. +- Added ImGuiStorage::GetVoidPtrRef() for manipulating stored void*. +- Added IsKeyDown() IsMouseDown() as convenience and for consistency with existing functions (instead of reading them from IO structures). +- Added Dummy() helper to advance layout by a given size. Unlike InvisibleButton() this doesn't catch any click. +- Added configurable io.KeyRepeatDelay, io.KeyRepeatRate keyboard and mouse repeat rate. +- Added PushButtonRepeat() / PopButtonRepeat() to enable hold-button-to-repeat press on any button. +- Removed the third 'repeat' parameter of Button(). +- Added IsAnyItemHovered() helper. +- Added GetItemsLineHeightWithSpacing() helper. +- Added ImGuiListClipper helper for clipping large list of evenly sized items, to avoid using CalcListClipping() directly. +- Separator: within group start on group horizontal offset. (#205) +- InputText: Fixed incorrect edit state after text buffer is appended to by user via the callback. (#206) +- InputText: CTRL+letter-key shortcuts (e.g. CTRL+C/V/X) makes sure only CTRL is pressed. (#214) +- InputText: Fixed cursor generating a zero-width wire-frame rectangle turning into a division by zero (would go unnoticed + unless you trapped exceptions). +- InputFloatN/InputIntN: Flags parameter added to match scalar versions. (#218) +- Selectable: Horizontal filling not declared to ItemSize() so Selectable(),SameLine() works and we can better auto-fit the window. +- Selectable: Handling text baseline alignment for line that aren't of text height. +- Combo: Empty label doesn't add ItemInnerSpacing alignment, matching other widgets. +- EndGroup: Carries the text base offset from the last line of the group (sort of incorrect but better than nothing, + should use the first line of the group, will implement in the future). +- Columns: distinguish columns-set ID from other widgets as a convenience, added asserts and sailors. +- ListBox: ListBox() function only use public API to encourage creating custom versions. ListBoxHeader() can return false. +- ListBox: Uses ImGuiListClipper and assume items of matching height, so large lists can be handled. +- Plot: overlay label clipped within frame when not fitting. +- Window: Added ImGuiSetCond_Appearing to test the hidden->visible transition in SetWindow***/SetNextWindow*** functions. +- Window: Auto-fitting cancel out one worth of vertical spacing for vertical symmetry (like what group and tooltip do). +- Window: Default item width for auto-resizing windows expressed as a factor of font height, scales better with different font. +- Window: Fixed auto-fit calculation mismatch of whether a scrollbar will be added by maximum height clamping. Also honor NoScrollBar in the case of height clamping, not adding extra horizontal space. +- Window: Hovering require to hover same child window. Reverted 860cf57 (December 3). Might break something if you have + child overlapping items in parent window. +- Window: Fixed appending multiple times to an existing child via multiple BeginChild/EndChild calls to same child name. + Allows a simple form of out-of-order appending. +- Window: Fixed auto-filling child window using WindowMinSize at their minimum size, irrelevant. +- Metrics: Added io.MetricsActiveWindows counter. (#213. +- Metrics: Added io.MetricsAllocs counter (number of active memory allocations). +- Metrics: ShowMetricsWindow() shows popups stack, allocations. +- Style: Added style.DisplayWindowPadding to prevent windows from reaching edges of display (similar to style.DisplaySafeAreaPadding which is still in effect and also affect popups/tooltips). +- Style: Removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same). +- Style: Added style.ScrollbarRounding. (#212) +- Style: Added ImGuiCol_TextDisabled for disabled text. Added TextDisabled() helper. +- Style: Added style.WindowTitleAlign alignment options, to e.g. center title on windows. (#222) +- ImVector: tweak growth strategy, matches vector from VS2010. +- ImFontAtlas: Added ClearFonts(), making the different clear funcs more explicit. (#224) +- ImFontAtlas: Fixed appending new fonts without clearing existing fonts. Clearing input data left to application. (#224) +- ImDrawList: Merge draw command better, cases of multiple Begin/End gets merged properly. +- Store common stacked settings contiguously in memory to avoid heap allocation for unused features, and reduce cache misses. +- Shutdown() tests for g.IO.Fonts not being NULL to ease use of multiple ImGui contexts. (#207) +- Added IMGUI_DISABLE_OBSOLETE_FUNCTIONS define to disable the functions that are meant to be removed. +- Examples: Added ? marks with tooltips next to various widgets. Added more comments in the demo window. +- Examples: Added Menu-bar example. +- Examples: Added Simple Layout example. +- Examples: AutoResize demo doesn't use TextWrapped(). +- Examples: Console example uses standard malloc/free, makes more sense as a copy & pastable example. +- Examples: DirectX9/11: Fixed key mapping for down arrow. +- Examples: DirectX9/11: hide OS cursor if ImGui is drawing it. (#155) +- Examples: DirectX11: explicitly set rasterizer state. +- Examples: OpenGL3: Add conditional compilation of forward compat as required by glfw on OSX.

Because UI rendering and interaction happens on the same plane +as the mouse, that disconnect may be jarring to particularly sensitive users. +You may experiment with enabling the io.MouseDrawCursor flag to request Dear ImGui to draw a mouse cursor +using the regular graphics API, to help you visualize the difference between a "hardware" cursor and a +regularly rendered software cursor. +However, rendering a mouse cursor at 60 FPS will feel sluggish so you likely won't want to enable that at +all times. It might be beneficial for the user experience to switch to a software rendered cursor _only_ +when an interactive drag is in progress. + +Note that some setup or GPU drivers are likely to be causing extra display lag depending on their settings. +If you feel that dragging windows feels laggy and you are not sure what the cause is: try to build a simple +drawing a flat 2D shape directly under the mouse cursor! + diff --git a/subprojects/imgui-1.81/docs/FAQ.md b/subprojects/imgui-1.81/docs/FAQ.md new file mode 100644 index 0000000..2d5e806 --- /dev/null +++ b/subprojects/imgui-1.81/docs/FAQ.md @@ -0,0 +1,652 @@ +# FAQ (Frequenty Asked Questions) + +You may link to this document using short form: + https://www.dearimgui.org/faq +or its real address: + https://github.com/ocornut/imgui/blob/master/docs/FAQ.md +or view this file with any Markdown viewer. + + +## Index + +| **Q&A: Basics** | +:---------------------------------------------------------- | +| [Where is the documentation?](#q-where-is-the-documentation) | +| [What is this library called?](#q-what-is-this-library-called) | +| [Which version should I get?](#q-which-version-should-i-get) | +| **Q&A: Integration** | +| **[How to get started?](#q-how-to-get-started)** | +| **[How can I tell whether to dispatch mouse/keyboard to Dear ImGui or to my application?](#q-how-can-i-tell-whether-to-dispatch-mousekeyboard-to-dear-imgui-or-to-my-application)** | +| [How can I enable keyboard or gamepad controls?](#q-how-can-i-enable-keyboard-or-gamepad-controls) | +| [How can I use this on a machine without mouse, keyboard or screen?

What is this library called? + +**This library is called Dear ImGui**. Please refer to it as Dear ImGui (not ImGui, not IMGUI). + +(The library misleadingly started its life in 2014 as "ImGui" due to the fact that I didn't give it a proper name when when I released 1.0, and had no particular expectation that it would take off. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations e.g. Unity uses it own implementation of the IMGUI paradigm. To reduce the ambiguity without affecting existing code bases, I have decided in December 2015 a fully qualified name "Dear ImGui" for this library. + +##### [Return to Index](#index) + +--- + +### Q: Which version should I get? +I occasionally tag [Releases](https://github.com/ocornut/imgui/releases) but it is generally safe and recommended to sync to master/latest. The library is fairly stable and regressions tend to be fixed fast when reported. + +You may use the [docking](https://github.com/ocornut/imgui/tree/docking) branch which includes: +- [Docking features](https://github.com/ocornut/imgui/issues/2109) +- [Multi-viewport features](https://github.com/ocornut/imgui/issues/1542) + +Many projects are using this branch and it is kept in sync with master regularly. + +You may merge in the [tables](https://github.com/ocornut/imgui/tree/tables) branch which includes: +- [Table features](https://github.com/ocornut/imgui/issues/2957) + +##### [Return to Index](#index) + +---- + +# Q&A: Integration + +### Q: How to get started? + +Read [EXAMPLES.md](https://github.com/ocornut/imgui/blob/master/docs/EXAMPLES.md). <BR> +Read [BACKENDS.md](https://github.com/ocornut/imgui/blob/master/docs/BACKENDS.md). <BR> +Read `PROGRAMMER GUIDE` section of [imgui.cpp](https://github.com/ocornut/imgui/blob/master/imgui.cpp). + +##### [Return to Index](#index) + +--- + +### Q: How can I tell whether to dispatch mouse/keyboard to Dear ImGui or to my application? + +You can read the `io.WantCaptureMouse`, `io.WantCaptureKeyboard` and `io.WantTextInput` flags from the ImGuiIO structure. + +e.g. `if (ImGui::GetIO().WantCaptureMouse) { ... }` + +- When `io.WantCaptureMouse` is set, imgui wants to use your mouse state, and you may want to discard/hide the inputs from the rest of your application. +- When `io.WantCaptureKeyboard` is set, imgui wants to use your keyboard state, and you may want to discard/hide the inputs from the rest of your application. +- When `io.WantTextInput` is set to may want to notify your OS to popup an on-screen keyboard, if available (e.g. on a mobile phone, or console OS). + +**Note:** You should always pass your mouse/keyboard inputs to Dear ImGui, even when the io.WantCaptureXXX flag are set false. + This is because imgui needs to detect that you clicked in the void to unfocus its own windows. + +**Note:** The `io.WantCaptureMouse` is more correct that any manual attempt to "check if the mouse is hovering a window" (don't do that!). It handle mouse dragging correctly (both dragging that started over your application or over a Dear ImGui window) and handle e.g. popup and modal windows blocking inputs. + +**Note:** Those flags are updated by `ImGui::NewFrame()`. However it is generally more correct and easier that you poll flags from the previous frame, then submit your inputs, then call `NewFrame()`. If you attempt to do the opposite (which is generally harder) you are likely going to submit your inputs after `NewFrame()`, and therefore too late. + +**Note:** If you are using a touch device, you may find use for an early call to `UpdateHoveredWindowAndCaptureFlags()` to correctly dispatch your initial touch. We will work on better out-of-the-box touch support in the future. + +**Note:** Text input widget releases focus on the "KeyDown" event of the Return key, so the subsequent "KeyUp" event that your application receive will typically have `io.WantCaptureKeyboard == false`. Depending on your application logic it may or not be inconvenient to receive that KeyUp event. You might want to track which key-downs were targeted for Dear ImGui, e.g. with an array of bool, and filter out the corresponding key-ups.) + +##### [Return to Index](#index) + +--- + +### Q: How can I enable keyboard or gamepad controls? +- The gamepad/keyboard navigation is fairly functional and keeps being improved. The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable. Gamepad support is particularly useful to use Dear ImGui on a game console (e.g. PS4, Switch, XB1) without a mouse connected! +- Keyboard: set `io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard` to enable. +- Gamepad: set `io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad` to enable (with a supporting backend). +- See [Control Sheets for Gamepads](http://www.dearimgui.org/controls_sheets) (reference PNG/PSD for for PS4, XB1, Switch gamepads). +- See `USING GAMEPAD/KEYBOARD NAVIGATION CONTROLS` section of [imgui.cpp](https://github.com/ocornut/imgui/blob/master/imgui.cpp) for more details. + +##### [Return to Index](#index) + +--- + +### Q: How can I use this on a machine without mouse, keyboard or screen? (input share, remote display) +- You can share your computer mouse seamlessly with your console/tablet/phone using solutions such as [Synergy](https://symless.com/synergy) +This is the preferred solution for developer productivity. +In particular, the [micro-synergy-client repository](https://github.com/symless/micro-synergy-client) has simple +and portable source code (uSynergy.c/.h) for a small embeddable client that you can use on any platform to connect +to your host computer, based on the Synergy 1.x protocol. Make sure you download the Synergy 1 server on your computer. +Console SDK also sometimes provide equivalent tooling or wrapper for Synergy-like protocols. +- Game console users: consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback. +- You may also use a third party solution such as [netImgui](https://github.com/sammyfreg/netImgui), [Remote ImGui](https://github.com/JordiRos/remoteimgui) or [imgui-ws](https://github.com/ggerganov/imgui-ws) which sends the vertices to render over the local network, allowing you to use Dear ImGui even on a screen-less machine. See [Wiki](https://github.com/ocornut/imgui/wiki) index for most details. +- For touch inputs, you can increase the hit box of widgets (via the `style.TouchPadding` setting) to accommodate for the lack of precision of touch inputs, but it is recommended you use a mouse or gamepad to allow optimizing for screen real-estate and precision. + +##### [Return to Index](#index) + +--- + +### Q: I integrated Dear ImGui in my engine and little squares are showing instead of text.. +This usually means that: your font texture wasn't uploaded into GPU, or your shader or other rendering state are not reading from the right texture (e.g. texture wasn't bound). +If this happens using the standard backends it is probably that the texture failed to upload, which could happens if for some reason your texture is too big. Also see [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md). + +##### [Return to Index](#index) + +--- + +### Q: I integrated Dear ImGui in my engine and some elements are clipping or disappearing when I move windows around.. +### Q: I integrated Dear ImGui in my engine and some elements are displaying outside their expected windows boundaries.. +You are probably mishandling the clipping rectangles in your render function. +Each draw command needs the triangle rendered using the clipping rectangle provided in the ImDrawCmd structure (`ImDrawCmd->CllipRect`). +Rectangles provided by Dear ImGui are defined as +`(x1=left,y1=top,x2=right,y2=bottom)` +and **NOT** as +`(x1,y1,width,height)` +Refer to rendering backends in the [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder for references of how to handle the `ClipRect` field. + +##### [Return to Index](#index) + +--- + +# Q&A: Usage + +### Q: Why is my widget not reacting when I click on it? +### Q: How can I have widgets with an empty label? +### Q: How can I have multiple widgets with the same label? + +A primer on labels and the ID Stack... + +Dear ImGui internally need to uniquely identify UI elements. +Elements that are typically not clickable (such as calls to the Text functions) don't need an ID. +Interactive widgets (such as calls to Button buttons) need a unique ID. +Unique ID are used internally to track active widgets and occasionally associate state to widgets. +Unique ID are implicitly built from the hash of multiple elements that identify the "path" to the UI element. + +- Unique ID are often derived from a string label and at minimum scoped within their host window: +```cpp +Begin("MyWindow"); +Button("OK"); // Label = "OK", ID = hash of ("MyWindow", "OK") +Button("Cancel"); // Label = "Cancel", ID = hash of ("MyWindow", "Cancel") +End(); +``` +- Other elements such as tree nodes, etc. also pushes to the ID stack: +```cpp +Begin("MyWindow"); +if (TreeNode("MyTreeNode")) +{ + Button("OK"); // Label = "OK", ID = hash of ("MyWindow", "MyTreeNode", "OK") + TreePop(); +} +End(); +``` +- Two items labeled "OK" in different windows or different tree locations won't collide: +```cpp +Begin("MyFirstWindow"); +Button("OK"); // Label = "OK", ID = hash of ("MyFirstWindow", "OK") +End(); +Begin("MyOtherWindow"); +Button("OK"); // Label = "OK", ID = hash of ("MyOtherWindow", "OK") +End(); +``` + +- If you have a same ID twice in the same location, you'll have a conflict: +```cpp +Button("OK"); +Button("OK"); // ID collision! Interacting with either button will trigger the first one. +``` +Fear not! this is easy to solve and there are many ways to solve it! + +- Solving ID conflict in a simple/local context: +When passing a label you can optionally specify extra ID information within string itself. +Use "##" to pass a complement to the ID that won't be visible to the end-user. +This helps solving the simple collision cases when you know e.g. at compilation time which items +are going to be created: +```cpp +Begin("MyWindow"); +Button("Play"); // Label = "Play", ID = hash of ("MyWindow", "Play") +Button("Play##foo1"); // Label = "Play", ID = hash of ("MyWindow", "Play##foo1") // Different from above +Button("Play##foo2"); // Label = "Play", ID = hash of ("MyWindow", "Play##foo2") // Different from above +End(); +``` +- If you want to completely hide the label, but still need an ID: +```cpp +Checkbox("##On", &b); // Label = "", ID = hash of (..., "##On") // No visible label, just a checkbox! +``` +- Occasionally/rarely you might want change a label while preserving a constant ID. This allows +you to animate labels. For example you may want to include varying information in a window title bar, +but windows are uniquely identified by their ID. Use "###" to pass a label that isn't part of ID: +```cpp +Button("Hello###ID"); // Label = "Hello", ID = hash of (..., "###ID") +Button("World###ID"); // Label = "World", ID = hash of (..., "###ID") // Same ID, different label + +sprintf(buf, "My game (%f FPS)###MyGame", fps); +Begin(buf); // Variable title, ID = hash of "MyGame" +``` +- Solving ID conflict in a more general manner: +Use PushID() / PopID() to create scopes and manipulate the ID stack, as to avoid ID conflicts +within the same window. This is the most convenient way of distinguishing ID when iterating and +creating many UI elements programmatically. +You can push a pointer, a string or an integer value into the ID stack. +Remember that ID are formed from the concatenation of _everything_ pushed into the ID stack. +At each level of the stack we store the seed used for items at this level of the ID stack. +```cpp +Begin("Window"); +for (int i = 0; i < 100; i++) +{ + PushID(i); // Push i to the id tack + Button("Click"); // Label = "Click", ID = hash of ("Window", i, "Click") + PopID(); +} +for (int i = 0; i < 100; i++) +{ + MyObject* obj = Objects[i]; + PushID(obj); + Button("Click"); // Label = "Click", ID = hash of ("Window", obj pointer, "Click") + PopID(); +} +for (int i = 0; i < 100; i++) +{ + MyObject* obj = Objects[i]; + PushID(obj->Name); + Button("Click"); // Label = "Click", ID = hash of ("Window", obj->Name, "Click") + PopID(); +} +End(); +``` +- You can stack multiple prefixes into the ID stack: +```cpp +Button("Click"); // Label = "Click", ID = hash of (..., "Click") +PushID("node"); + Button("Click"); // Label = "Click", ID = hash of (..., "node", "Click") + PushID(my_ptr); + Button("Click"); // Label = "Click", ID = hash of (..., "node", my_ptr, "Click") + PopID(); +PopID(); +``` +- Tree nodes implicitly creates a scope for you by calling PushID(). +```cpp +Button("Click"); // Label = "Click", ID = hash of (..., "Click") +if (TreeNode("node")) // <-- this function call will do a PushID() for you (unless instructed not to, with a special flag) +{ + Button("Click"); // Label = "Click", ID = hash of (..., "node", "Click") + TreePop(); +} +``` + +When working with trees, ID are used to preserve the open/close state of each tree node. +Depending on your use cases you may want to use strings, indices or pointers as ID. +- e.g. when following a single pointer that may change over time, using a static string as ID +will preserve your node open/closed state when the targeted object change. +- e.g. when displaying a list of objects, using indices or pointers as ID will preserve the +node open/closed state differently. See what makes more sense in your situation! + +##### [Return to Index](#index) + +--- + +### Q: How can I display an image? What is ImTextureID, how does it work? + +Short explanation: +- Refer to [Image Loading and Displaying Examples](https://github.com/ocornut/imgui/wiki/Image-Loading-and-Displaying-Examples) on the [Wiki](https://github.com/ocornut/imgui/wiki). +- You may use functions such as `ImGui::Image()`, `ImGui::ImageButton()` or lower-level `ImDrawList::AddImage()` to emit draw calls that will use your own textures. +- Actual textures are identified in a way that is up to the user/engine. Those identifiers are stored and passed as ImTextureID (void*) value. +- Loading image files from the disk and turning them into a texture is not within the scope of Dear ImGui (for a good reason). + +**Please read documentations or tutorials on your graphics API to understand how to display textures on the screen before moving onward.** + +Long explanation: +- Dear ImGui's job is to create "meshes", defined in a renderer-agnostic format made of draw commands and vertices. At the end of the frame those meshes (ImDrawList) will be displayed by your rendering function. They are made up of textured polygons and the code to render them is generally fairly short (a few dozen lines). In the examples/ folder we provide functions for popular graphics API (OpenGL, DirectX, etc.). +- Each rendering function decides on a data type to represent "textures". The concept of what is a "texture" is entirely tied to your underlying engine/graphics API. + We carry the information to identify a "texture" in the ImTextureID type. +ImTextureID is nothing more that a void*, aka 4/8 bytes worth of data: just enough to store 1 pointer or 1 integer of your choice. +Dear ImGui doesn't know or understand what you are storing in ImTextureID, it merely pass ImTextureID values until they reach your rendering function. +- In the [examples/](https://github.com/ocornut/imgui/tree/master/examples) backends, for each graphics API we decided on a type that is likely to be a good representation for specifying an image from the end-user perspective. This is what the _examples_ rendering functions are using: +```cpp +OpenGL: +- ImTextureID = GLuint +- See ImGui_ImplOpenGL3_RenderDrawData() function in imgui_impl_opengl3.cpp +``` +```cpp +DirectX9: +- ImTextureID = LPDIRECT3DTEXTURE9 +- See ImGui_ImplDX9_RenderDrawData() function in imgui_impl_dx9.cpp +``` +```cpp +DirectX11: +- ImTextureID = ID3D11ShaderResourceView* +- See ImGui_ImplDX11_RenderDrawData() function in imgui_impl_dx11.cpp +``` +```cpp +DirectX12: +- ImTextureID = D3D12_GPU_DESCRIPTOR_HANDLE +- See ImGui_ImplDX12_RenderDrawData() function in imgui_impl_dx12.cpp +``` +For example, in the OpenGL example backend we store raw OpenGL texture identifier (GLuint) inside ImTextureID. +Whereas in the DirectX11 example backend we store a pointer to ID3D11ShaderResourceView inside ImTextureID, which is a higher-level structure tying together both the texture and information about its format and how to read it. + +- If you have a custom engine built over e.g. OpenGL, instead of passing GLuint around you may decide to use a high-level data type to carry information about the texture as well as how to display it (shaders, etc.). The decision of what to use as ImTextureID can always be made better knowing how your codebase is designed. If your engine has high-level data types for "textures" and "material" then you may want to use them. +If you are starting with OpenGL or DirectX or Vulkan and haven't built much of a rendering engine over them, keeping the default ImTextureID representation suggested by the example backends is probably the best choice. +(Advanced users may also decide to keep a low-level type in ImTextureID, and use ImDrawList callback and pass information to their renderer) + +User code may do: +```cpp +// Cast our texture type to ImTextureID / void* +MyTexture* texture = g_CoffeeTableTexture; +ImGui::Image((void*)texture, ImVec2(texture->Width, texture->Height)); +``` +The renderer function called after ImGui::Render() will receive that same value that the user code passed: +```cpp +// Cast ImTextureID / void* stored in the draw command as our texture type +MyTexture* texture = (MyTexture*)pcmd->TextureId; +MyEngineBindTexture2D(texture); +``` +Once you understand this design you will understand that loading image files and turning them into displayable textures is not within the scope of Dear ImGui. +This is by design and is actually a good thing, because it means your code has full control over your data types and how you display them. +If you want to display an image file (e.g. PNG file) into the screen, please refer to documentation and tutorials for the graphics API you are using. + +Refer to [Image Loading and Displaying Examples](https://github.com/ocornut/imgui/wiki/Image-Loading-and-Displaying-Examples) on the [Wiki](https://github.com/ocornut/imgui/wiki) to find simplified examples for loading textures with OpenGL, DirectX9 and DirectX11. + +C/C++ tip: a void* is pointer-sized storage. You may safely store any pointer or integer into it by casting your value to ImTextureID / void*, and vice-versa. +Because both end-points (user code and rendering function) are under your control, you know exactly what is stored inside the ImTextureID / void*. +Examples: +```cpp +GLuint my_tex = XXX; +void* my_void_ptr; +my_void_ptr = (void*)(intptr_t)my_tex; // cast a GLuint into a void* (we don't take its address! we literally store the value inside the pointer) +my_tex = (GLuint)(intptr_t)my_void_ptr; // cast a void* into a GLuint + +ID3D11ShaderResourceView* my_dx11_srv = XXX; +void* my_void_ptr; +my_void_ptr = (void*)my_dx11_srv; // cast a ID3D11ShaderResourceView* into an opaque void* +my_dx11_srv = (ID3D11ShaderResourceView*)my_void_ptr; // cast a void* into a ID3D11ShaderResourceView* +``` +Finally, you may call `ImGui::ShowMetricsWindow()` to explore/visualize/understand how the ImDrawList are generated. + +##### [Return to Index](#index) + +--- + +### Q: How can I use my own math types instead of ImVec2/ImVec4? + +You can edit [imconfig.h](https://github.com/ocornut/imgui/blob/master/imconfig.h) and setup the `IM_VEC2_CLASS_EXTRA`/`IM_VEC4_CLASS_EXTRA` macros to add implicit type conversions. +This way you'll be able to use your own types everywhere, e.g. passing `MyVector2` or `glm::vec2` to ImGui functions instead of `ImVec2`. + +##### [Return to Index](#index) + +--- + +### Q: How can I interact with standard C++ types (such as std::string and std::vector)? +- Being highly portable (backends/bindings for several languages, frameworks, programming style, obscure or older platforms/compilers), and aiming for compatibility & performance suitable for every modern real-time game engines, dear imgui does not use any of std C++ types. We use raw types (e.g. char* instead of std::string) because they adapt to more use cases. +- To use ImGui::InputText() with a std::string or any resizable string class, see [misc/cpp/imgui_stdlib.h](https://github.com/ocornut/imgui/blob/master/misc/cpp/imgui_stdlib.h). +- To use combo boxes and list boxes with `std::vector` or any other data structure: the `BeginCombo()/EndCombo()` API +lets you iterate and submit items yourself, so does the `ListBoxHeader()/ListBoxFooter()` API. +Prefer using them over the old and awkward `Combo()/ListBox()` api. +- Generally for most high-level types you should be able to access the underlying data type. +You may write your own one-liner wrappers to facilitate user code (tip: add new functions in ImGui:: namespace from your code). +- Dear ImGui applications often need to make intensive use of strings. It is expected that many of the strings you will pass +to the API are raw literals (free in C/C++) or allocated in a manner that won't incur a large cost on your application. +Please bear in mind that using `std::string` on applications with large amount of UI may incur unsatisfactory performances. +Modern implementations of `std::string` often include small-string optimization (which is often a local buffer) but those +are not configurable and not the same across implementations. +- If you are finding your UI traversal cost to be too large, make sure your string usage is not leading to excessive amount +of heap allocations. Consider using literals, statically sized buffers and your own helper functions.

(using low-level ImDrawList API) + +- You can use the low-level `ImDrawList` api to render shapes within a window. +```cpp +ImGui::Begin("My shapes"); + +ImDrawList* draw_list = ImGui::GetWindowDrawList(); + +// Get the current ImGui cursor position +ImVec2 p = ImGui::GetCursorScreenPos(); + +// Draw a red circle +draw_list->AddCircleFilled(ImVec2(p.x + 50, p.y + 50), 30.0f, IM_COL32(255, 0, 0, 255), 16); + +// Draw a 3 pixel thick yellow line +draw_list->AddLine(ImVec2(p.x, p.y), ImVec2(p.x + 100.0f, p.y + 100.0f), IM_COL32(255, 255, 0, 255), 3.0f); + +// Advance the ImGui cursor to claim space in the window (otherwise the window will appears small and needs to be resized) +ImGui::Dummy(ImVec2(200, 200)); + +ImGui::End(); +``` + + +- Refer to "Demo > Examples > Custom Rendering" in the demo window and read the code of `ShowExampleAppCustomRendering()` in `imgui_demo.cpp` from more examples. +- To generate colors: you can use the macro `IM_COL32(255,255,255,255)` to generate them at compile time, or use `ImGui::GetColorU32(IM_COL32(255,255,255,255))` or `ImGui::GetColorU32(ImVec4(1.0f,1.0f,1.0f,1.0f))` to generate a color that is multiplied by the current value of `style.Alpha`. +- Math operators: if you have setup `IM_VEC2_CLASS_EXTRA` in `imconfig.h` to bind your own math types, you can use your own math types and their natural operators instead of ImVec2. ImVec2 by default doesn't export any math operators in the public API. You may use `#define IMGUI_DEFINE_MATH_OPERATORS` `#include "imgui_internal.h"` to use the internally defined math operators, but instead prefer using your own math library and set it up in `imconfig.h`. +- You can use `ImGui::GetBackgroundDrawList()` or `ImGui::GetForegroundDrawList()` to access draw lists which will be displayed behind and over every other dear imgui windows (one bg/fg drawlist per viewport). This is very convenient if you need to quickly display something on the screen that is not associated to a dear imgui window. +- You can also create your own empty window and draw inside it. Call Begin() with the NoBackground | NoDecoration | NoSavedSettings | NoInputs flags (The `ImGuiWindowFlags_NoDecoration` flag itself is a shortcut for NoTitleBar | NoResize | NoScrollbar | NoCollapse). Then you can retrieve the ImDrawList* via GetWindowDrawList() and draw to it in any way you like. +- You can create your own ImDrawList instance. You'll need to initialize them with `ImGui::GetDrawListSharedData()`, or create your own instancing ImDrawListSharedData, and then call your renderer function with your own ImDrawList or ImDrawData data. + +##### [Return to Index](#index) + +--- + +# Q&A: Fonts, Text + +### Q: How should I handle DPI in my application? + +The short answer is: obtain the desired DPI scale, load your fonts resized with that scale (always round down fonts size to nearest integer), and scale your Style structure accordingly using `style.ScaleAllSizes()`. + +Your application may want to detect DPI change and reload the fonts and reset style between frames. + +Your ui code should avoid using hardcoded constants for size and positioning. Prefer to express values as multiple of reference values such as `ImGui::GetFontSize()` or `ImGui::GetFrameHeight()`. So e.g. instead of seeing a hardcoded height of 500 for a given item/window, you may want to use `30*ImGui::GetFontSize()` instead. + +Down the line Dear ImGui will provide a variety of standardized reference values to facilitate using this. + +Applications in the `examples/` folder are not DPI aware partly because they are unable to load a custom font from the file-system (may change that in the future). + +The reason DPI is not auto-magically solved in stock examples is that we don't yet have a satisfying solution for the "multi-dpi" problem (using the `docking` branch: when multiple viewport windows are over multiple monitors using different DPI scale). The current way to handle this on the application side is: +- Create and maintain one font atlas per active DPI scale (e.g. by iterating `platform_io.Monitors[]` before `NewFrame()`). +- Hook `platform_io.OnChangedViewport()` to detect when a `Begin()` call makes a Dear ImGui window change monitor (and therefore DPI). +- In the hook: swap atlas, swap style with correctly sized one, remap the current font from one atlas to the other (may need to maintain a remapping table of your fonts at variying DPI scale). + +This approach is relatively easy and functional but come with two issues: +- It's not possibly to reliably size or position a window ahead of `Begin()` without knowing on which monitor it'll land. +- Style override may be lost during the `Begin()` call crossing monitor boundaries. You may need to do some custom scaling mumbo-jumbo if you want your `OnChangedViewport()` handler to preserve style overrides. + +Please note that if you are not using multi-viewports with multi-monitors using different DPI scale, you can ignore all of this and use the simpler technique recommended at the top. + +### Q: How can I load a different font than the default? +Use the font atlas to load the TTF/OTF file you want: + +```cpp +ImGuiIO& io = ImGui::GetIO(); +io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels); +io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8() +``` + +Default is ProggyClean.ttf, monospace, rendered at size 13, embedded in dear imgui's source code. + +(Tip: monospace fonts are convenient because they allow to facilitate horizontal alignment directly at the string level.) + +(Read the [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md) file for more details about font loading.) + +New programmers: remember that in C/C++ and most programming languages if you want to use a +backslash \ within a string literal, you need to write it double backslash "\\": + +```cpp +io.Fonts->AddFontFromFileTTF("MyFolder\MyFont.ttf", size); // WRONG (you are escaping the M here!) +io.Fonts->AddFontFromFileTTF("MyFolder\\MyFont.ttf", size; // CORRECT (Windows only) +io.Fonts->AddFontFromFileTTF("MyFolder/MyFont.ttf", size); // ALSO CORRECT +``` + +##### [Return to Index](#index) + +--- + +### Q: How can I easily use icons in my application? +The most convenient and practical way is to merge an icon font such as FontAwesome inside you +main font.

You can alter the look of the interface to some degree: changing colors, sizes, padding, rounding, fonts.

Dear ImGui does NOT require C++11 so it can be used with most old C++ compilers. Dear ImGui doesn't use any C++ header file. Language-wise, function overloading and default parameters are used to make the API easier to use and code more terse. Doing so I believe the API is sitting on a sweet spot and giving up on those features would make the API more cumbersome.

It is fast, portable, renderer agnostic and self-contained (no external dependencies). + +Dear ImGui is designed to **enable fast iterations** and to **empower programmers** to create **content creation tools and visualization / debug tools** (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal, and lacks certain features normally found in more high-level libraries. + +Dear ImGui is particularly suited to integration in games engine (for tooling), real-time 3D applications, fullscreen applications, embedded applications, or any applications on consoles platforms where operating system features are non-standard. + +| [Usage](#usage) - [How it works](#how-it-works) - [Releases & Changelogs](#releases--changelogs) - [Demo](#demo) - [Integration](#integration) | +:----------------------------------------------------------: | +| [Upcoming changes](#upcoming-changes) - [Gallery](#gallery) - [Support, FAQ](#support-frequently-asked-questions-faq) - [How to help](#how-to-help) - [Sponsors](#sponsors) - [Credits](#credits) - [License](#license) | +| [Wiki](https://github.com/ocornut/imgui/wiki) - [Languages & frameworks backends/bindings](https://github.com/ocornut/imgui/wiki/Bindings) - [Software using Dear ImGui](https://github.com/ocornut/imgui/wiki/Software-using-dear-imgui) - [User quotes](https://github.com/ocornut/imgui/wiki/Quotes) | + +### Usage + +**The core of Dear ImGui is self-contained within a few platform-agnostic files** which you can easily compile in your application/engine. They are all the files in the root folder of the repository (imgui.cpp, imgui.h, imgui_demo.cpp, imgui_draw.cpp etc.). + +**No specific build process is required**. You can add the .cpp files to your existing project. + +You will need a backend to integrate Dear ImGui in your app. The backend passes mouse/keyboard/gamepad inputs and variety of settings to Dear ImGui, and is in charge of rendering the resulting vertices. + +**Backends for a variety of graphics api and rendering platforms** are provided in the [backends/](https://github.com/ocornut/imgui/tree/master/backends) folder, along with example applications in the [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder. See the [Integration](#integration) section of this document for details. You may also create your own backend. Anywhere where you can render textured triangles, you can render Dear ImGui. + +After Dear ImGui is setup in your application, you can use it from \_anywhere\_ in your program loop: + +Code: +```cpp +ImGui::Text("Hello, world %d", 123); +if (ImGui::Button("Save")) + MySaveFunction(); +ImGui::InputText("string", buf, IM_ARRAYSIZE(buf)); +ImGui::SliderFloat("float", &f, 0.0f, 1.0f); +``` +Result: +<br>  +<br>_(settings: Dark style (left), Light style (right) / Font: Roboto-Medium, 16px)_ + +Code: +```cpp +// Create a window called "My First Tool", with a menu bar. +ImGui::Begin("My First Tool", &my_tool_active, ImGuiWindowFlags_MenuBar); +if (ImGui::BeginMenuBar()) +{ + if (ImGui::BeginMenu("File")) + { + if (ImGui::MenuItem("Open..", "Ctrl+O")) { /* Do stuff */ } + if (ImGui::MenuItem("Save", "Ctrl+S")) { /* Do stuff */ } + if (ImGui::MenuItem("Close", "Ctrl+W")) { my_tool_active = false; } + ImGui::EndMenu(); + } + ImGui::EndMenuBar(); +} + +// Edit a color (stored as ~4 floats) +ImGui::ColorEdit4("Color", my_color); + +// Plot some values +const float my_values[] = { 0.2f, 0.1f, 1.0f, 0.5f, 0.9f, 2.2f }; +ImGui::PlotLines("Frame Times", my_values, IM_ARRAYSIZE(my_values)); + +// Display contents in a scrolling region +ImGui::TextColored(ImVec4(1,1,0,1), "Important Stuff"); +ImGui::BeginChild("Scrolling"); +for (int n = 0; n < 50; n++) + ImGui::Text("%04d: Some text", n); +ImGui::EndChild(); +ImGui::End(); +``` +Result: +<br> + +Dear ImGui allows you to **create elaborate tools** as well as very short-lived ones. On the extreme side of short-livedness: using the Edit&Continue (hot code reload) feature of modern compilers you can add a few widgets to tweaks variables while your application is running, and remove the code a minute later! Dear ImGui is not just for tweaking values. You can use it to trace a running algorithm by just emitting text commands. You can use it along with your own reflection data to browse your dataset live. You can use it to expose the internals of a subsystem in your engine, to create a logger, an inspection tool, a profiler, a debugger, an entire game making editor/framework, etc. + +### How it works + +Check out the Wiki's [About the IMGUI paradigm](https://github.com/ocornut/imgui/wiki#about-the-imgui-paradigm) section if you want to understand the core principles behind the IMGUI paradigm. An IMGUI tries to minimize superfluous state duplication, state synchronization and state retention from the user's point of view. It is less error prone (less code and less bugs) than traditional retained-mode interfaces, and lends itself to create dynamic user interfaces. + +Dear ImGui outputs vertex buffers and command lists that you can easily render in your application. The number of draw calls and state changes required to render them is fairly small. Because Dear ImGui doesn't know or touch graphics state directly, you can call its functions anywhere in your code (e.g. in the middle of a running algorithm, or in the middle of your own rendering process). Refer to the sample applications in the examples/ folder for instructions on how to integrate Dear ImGui with your existing codebase. + +_A common misunderstanding is to mistake immediate mode gui for immediate mode rendering, which usually implies hammering your driver/GPU with a bunch of inefficient draw calls and state changes as the gui functions are called. This is NOT what Dear ImGui does. Dear ImGui outputs vertex buffers and a small list of draw calls batches. It never touches your GPU directly. The draw call batches are decently optimal and you can render them later, in your app or even remotely._ + +### Releases & Changelogs + +See [Releases](https://github.com/ocornut/imgui/releases) page. +Reading the changelogs is a good way to keep up to date with the things Dear ImGui has to offer, and maybe will give you ideas of some features that you've been ignoring until now! + +### Demo + +Calling the `ImGui::ShowDemoWindow()` function will create a demo window showcasing variety of features and examples. The code is always available for reference in `imgui_demo.cpp`. + + + +You should be able to build the examples from sources (tested on Windows/Mac/Linux). If you don't, let us know! If you want to have a quick look at some Dear ImGui features, you can download Windows binaries of the demo app here: +- [imgui-demo-binaries-20200918.zip](https://www.dearimgui.org/binaries/imgui-demo-binaries-20200918.zip) (Windows, 1.78 WIP, built 2020/09/18, master branch) or [older demo binaries](https://www.dearimgui.org/binaries). + +The demo applications are not DPI aware so expect some blurriness on a 4K screen. For DPI awareness in your application, you can load/reload your font at different scale, and scale your style with `style.ScaleAllSizes()` (see [FAQ](https://www.dearimgui.org/faq)). + +### Integration + +On most platforms and when using C++, **you should be able to use a combination of the [imgui_impl_xxxx](https://github.com/ocornut/imgui/tree/master/backends) backends without modification** (e.g. `imgui_impl_win32.cpp` + `imgui_impl_dx11.cpp`). If your engine supports multiple platforms, consider using more of the imgui_impl_xxxx files instead of rewriting them: this will be less work for you and you can get Dear ImGui running immediately. You can _later_ decide to rewrite a custom backend using your custom engine functions if you wish so. + +Integrating Dear ImGui within your custom engine is a matter of 1) wiring mouse/keyboard/gamepad inputs 2) uploading one texture to your GPU/render engine 3) providing a render function that can bind textures and render textured triangles. The [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder is populated with applications doing just that. If you are an experienced programmer at ease with those concepts, it should take you less than two hours to integrate Dear ImGui in your custom engine. **Make sure to spend time reading the [FAQ](https://www.dearimgui.org/faq), comments, and some of the examples/ application!** + +Officially maintained backends/bindings (in repository): +- Renderers: DirectX9, DirectX10, DirectX11, DirectX12, Metal, OpenGL (legacy), OpenGL3/ES/ES2 (modern), Vulkan, WebGPU. +- Platforms: GLFW, SDL2, Win32, Glut, OSX. +- Frameworks: Emscripten, Allegro5, Marmalade. + +[Third-party backends/bindings](https://github.com/ocornut/imgui/wiki/Bindings) wiki page: +- Languages: C, C# and: Beef, ChaiScript, Crystal, D, Go, Haskell, Haxe/hxcpp, Java, JavaScript, Julia, Kotlin, Lobster, Lua, Odin, Pascal, PureBasic, Python, Ruby, Rust, Swift... +- Frameworks: AGS/Adventure Game Studio, Amethyst, Blender, bsf, Cinder, Cocos2d-x, Diligent Engine, Flexium, GML/Game Maker Studio2, GLEQ, Godot, GTK3+OpenGL3, Irrlicht Engine, LÖVE+LUA, Magnum, Monogame, NanoRT, nCine, Nim Game Lib, Nintendo 3DS & Switch (homebrew), Ogre, openFrameworks, OSG/OpenSceneGraph, Orx, Photoshop, px_render, Qt/QtDirect3D, SDL_Renderer, SFML, Sokol, Unity, Unreal Engine 4, vtk, VulkanHpp, VulkanSceneGraph, Win32 GDI, WxWidgets. +- Note that C bindings ([cimgui](https://github.com/cimgui/cimgui)) are auto-generated, you can use its json/lua output to generate bindings for other languages. + +[Useful widgets and extensions](https://github.com/ocornut/imgui/wiki/Useful-Widgets) wiki page: +- Text editors, node editors, timeline editors, plotting, software renderers, remote network access, memory editors, gizmos etc. + +Also see [Wiki](https://github.com/ocornut/imgui/wiki) for more links and ideas. + +### Upcoming Changes + +Some of the goals for 2021 are: +- Work on Docking (see [#2109](https://github.com/ocornut/imgui/issues/2109), in public [docking](https://github.com/ocornut/imgui/tree/docking) branch) +- Work on Multi-Viewport / Multiple OS windows.

(#690) + - window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. perhaps a lightweight explicit cleanup pass. + - window: auto-fit feedback loop when user relies on any dynamic layout (window width multiplier, column) appears weird to end-user. clarify. + - window: begin with *p_open == false could return false. + - window: get size/pos helpers given names (see discussion in #249) + - window: a collapsed window can be stuck behind the main menu bar? + - window: when window is very small, prioritize resize button over close button. + - window: detect extra End() call that pop the "Debug" window out and assert at End() call site instead of at end of frame. + - window: increase minimum size of a window with menus or fix the menu rendering so that it doesn't look odd. + - window: double-clicking on title bar to minimize isn't consistent, perhaps move to single-click on left-most collapse icon? + - window: expose contents size. (#1045) + - window: using SetWindowPos() inside Begin() and moving the window with the mouse reacts a very ugly glitch. We should just defer the SetWindowPos() call. + - window: GetWindowSize() returns (0,0) when not calculated? (#1045) + - window: investigate better auto-positioning for new windows. + - window: top most window flag? (#2574) + - window/size: manually triggered auto-fit (double-click on grip) shouldn't resize window down to viewport size? + - window/size: how to allow to e.g. auto-size vertically to fit contents, but be horizontally resizable? Assuming SetNextWindowSize() is modified to treat -1.0f on each axis as "keep as-is" (would be good but might break erroneous code): Problem is UpdateWindowManualResize() and lots of code treat (window->AutoFitFramesX > 0 || window->AutoFitFramesY > 0) together. + - window/opt: freeze window flag: if not focused/hovered, return false, render with previous ImDrawList. and/or reduce refresh rate. -> this may require enforcing that it is illegal to submit contents if Begin returns false. + - window/child: background options for child windows, border option (disable rounding). + - window/child: allow resizing of child windows (possibly given min/max for each axis?.) + - window/child: the first draw command of a child window could be moved into the current draw command of the parent window (unless child+tooltip?). + - window/child: border could be emitted in parent as well. + - window/child: allow SetNextWindowContentSize() to work on child windows. + - window/clipping: some form of clipping when DisplaySize (or corresponding viewport) is zero. + - window/tabbing: add a way to signify that a window or docked window requires attention (e.g. blinking title bar). + - window/id_stack: add e.g. window->GetIDFromPath() with support for leading / and ../ (#1390, #331) + ! scrolling: exposing horizontal scrolling with Shift+Wheel even when scrollbar is disabled expose lots of issues (#2424, #1463) + - scrolling: while holding down a scrollbar, try to keep the same contents visible (at least while not moving mouse) + - scrolling: allow immediately effective change of scroll after Begin() if we haven't appended items yet. + - scrolling: forward mouse wheel scrolling to parent window when at the edge of scrolling limits? (useful for listbox,tables?) + - scrolling/clipping: separator on the initial position of a window is not visible (cursorpos.y <= clippos.y). (2017-08-20: can't repro) + - scrolling/style: shadows on scrollable areas to denote that there is more contents (see e.g. DaVinci Resolve ui) + + - drawdata: make it easy to clone (or swap?) a full ImDrawData so user can easily save that data if they use threaded rendering. (e.g. #2646) + ! drawlist: add calctextsize func to facilitate consistent code from user pov (currently need to use ImGui or ImFont alternatives!) + - drawlist: end-user probably can't call Clear() directly because we expect a texture to be pushed in the stack. + - drawlist: maintaining bounding box per command would allow to merge draw command when clipping isn't relied on (typical non-scrolling window or non-overflowing column would merge with previous command). + - drawlist: primitives/helpers to manipulate vertices post submission, so e.g. a quad/rect can be resized to fit later submitted content, _without_ using the ChannelSplit api + - drawlist: make it easier to toggle AA per primitive, so we can use e.g. non-AA fill + AA borders more naturally + - drawlist: non-AA strokes have gaps between points (#593, #288), glitch especially on RenderCheckmark() and ColorPicker4(). + - drawlist: would be good to be able to deep copy of ImDrawData (we have a deep copy of ImDrawList now). + - drawlist: rendering: provide a way for imgui to output to a single/global vertex buffer, re-order indices only at the end of the frame (ref: https://gist.github.com/floooh/10388a0afbe08fce9e617d8aefa7d302) + - drawlist: callback: add an extra void* in ImDrawCallback to allow passing render-local data to the callback (would break API). + - drawlist: AddRect vs AddLine position confusing (#2441) + - drawlist: channel splitter should be external helper and not stored in ImDrawList. + - drawlist: Add quadratic bezier curves? (#3127) + - drawlist/opt: store rounded corners in texture to use 1 quad per corner (filled and wireframe) to lower the cost of rounding. (#1962) + - drawlist/opt: AddRect() axis aligned pixel aligned (no-aa) could use 8 triangles instead of 16 and no normal calculation. + - drawlist/opt: thick AA line could be doable in same number of triangles as 1.0 AA line by storing gradient+full color in atlas. + + - main: find a way to preserve relative orders of multiple reappearing windows (so an app toggling between "modes" e.g. fullscreen vs all tools) won't lose relative ordering. + - main: IsItemHovered() make it more consistent for various type of widgets, widgets with multiple components, etc. also effectively IsHovered() region sometimes differs from hot region, e.g tree nodes + - main: IsItemHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode? + + - widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc. (#395) + - widgets: clean up widgets internal toward exposing everything and stabilizing imgui_internals.h. + - widgets: add visuals for Disabled/ReadOnly mode and expose publicly (#211) + - widgets: add always-allow-overlap mode. This should perhaps be the default? one problem is that highlight after mouse-wheel scrolling gets deferred, makes scrolling more flickery. + - widgets: start exposing PushItemFlag() and ImGuiItemFlags + - widgets: alignment options in style (e.g. center Selectable, Right-Align within Button, etc.) #1260 + - widgets: activate by identifier (trigger button, focus given id) + - widgets: a way to represent "mixed" values, so e.g. all values replaced with *, including check-boxes, colors, etc. with support for multi-components widgets (e.g. SliderFloat3, make only "Y" mixed) (#2644) + - widgets: checkbox: checkbox with custom glyph inside frame. + - widgets: coloredit: keep reporting as active when picker is on? + - widgets: group/scalarn functions: expose more per-component information. e.g. store NextItemData.ComponentIdx set by scalarn function, groups can expose them back somehow. + - selectable: using (size.x == 0.0f) and (SelectableTextAlign.x > 0.0f) followed by SameLine() is currently not supported. + - selectable: generic BeginSelectable()/EndSelectable() mechanism. + - selectable: a way to visualize partial/mixed selection (e.g. parent tree node has children with mixed selection) + + - input text: clean up the mess caused by converting UTF-8 <> wchar. the code is rather inefficient right now and super fragile. + - input text: preserve scrolling when unfocused? + - input text: reorganize event handling, allow CharFilter to modify buffers, allow multiple events? (#541) + - input text: expose CursorPos in char filter event (#816) + - input text: try usage idiom of using InputText with data only exposed through get/set accessors, without extraneous copy/alloc. (#3009) + - input text: access public fields via a non-callback API e.g. InputTextGetState("xxx") that may return NULL if not active. + - input text: flag to disable live update of the user buffer (also applies to float/int text input) (#701) + - input text: hover tooltip could show unclamped text + - input text: option to Tab after an Enter validation. + - input text: add ImGuiInputTextFlags_EnterToApply? (off #218) + - input text: easier ways to update buffer (from source char*) while owned. preserve some sort of cursor position for multi-line text. + - input text: add flag (e.g. ImGuiInputTextFlags_EscapeClearsBuffer) to clear instead of revert. what to do with focus? (also see #2890) + - input text: add discard flag (e.g. ImGuiInputTextFlags_DiscardActiveBuffer) or make it easier to clear active focus for text replacement during edition (#725) + - input text: display bug when clicking a drag/slider after an input text in a different window has all-selected text (order dependent). actually a very old bug but no one appears to have noticed it. + - input text: allow centering/positioning text so that ctrl+clicking Drag or Slider keeps the textual value at the same pixel position. + - input text: decorrelate layout from inputs - e.g. what's the easiest way to implement a nice IP/Mac address input editor? + - input text: global callback system so user can plug in an expression evaluator easily. (#1691) + - input text: force scroll to end or scroll to a given line/contents (so user can implement a log or a search feature) + - input text: a way to preview completion (e.g. disabled text completing from the cursor) + - input text: a side bar that could e.g. preview where errors are. probably left to the user to draw but we'd need to give them the info there. + - input text: a way for the user to provide syntax coloring. + - input text: Shift+TAB with ImGuiInputTextFlags_AllowTabInput could eat preceding blanks, up to tab_count. + - input text: facilitate patterns like if (InputText(..., obj.get_string_ref()) { obj.set_string(...); } relying on internally held buffer. + - input text multi-line: don't directly call AddText() which does an unnecessary vertex reserve for character count prior to clipping. and/or more line-based clipping to AddText(). and/or reorganize TextUnformatted/RenderText for more efficiency for large text (e.g TextUnformatted could clip and log separately, etc). + - input text multi-line: support for cut/paste without selection (cut/paste the current line) + - input text multi-line: line numbers? status bar? (follow up on #200) + - input text multi-line: behave better when user changes input buffer while editing is active (even though it is illegal behavior). namely, the change of buffer can create a scrollbar glitch (#725) + - input text multi-line: better horizontal scrolling support (#383, #1224) + - input text multi-line: single call to AddText() should be coarse clipped on InputTextEx() end. + - input number: optional range min/max for Input*() functions + - input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled) + - input number: use mouse wheel to step up/down + - input number: applying arithmetics ops (+,-,*,/) messes up with text edit undo stack. + + - layout: helper or a way to express ImGui::SameLine(ImGui::GetCursorStartPos().x + ImGui::CalcItemWidth() + ImGui::GetStyle().ItemInnerSpacing.x); in a simpler manner. + - layout, font: horizontal tab support, A) text mode: forward only tabs (e.g. every 4 characters/N pixels from pos x1), B) manual mode: explicit tab stops acting as mini columns, no clipping (for menu items, many kind of uses, also vaguely relate to #267, #395) + - layout: horizontal layout helper (#97) + - layout: horizontal flow until no space left (#404) + - layout: more generic alignment state (left/right/centered) for single items? + - layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 layout code. item width should include frame padding. + - layout: vertical alignment of mixed height items (e.g. buttons) within a same line (#1284) + - layout: null layout mode were items are not rendered but user can query GetItemRectMin()/Max/Size. + - layout: (R&D) local multi-pass layout mode. + - layout: (R&D) bind authored layout data (created by an off-line tool), items fetch their pos/size at submission, self-optimize data structures to stable linear access. + + - group: BeginGroup() needs a border option. (~#1496) + - group: IsHovered() after EndGroup() covers whole aabb rather than the intersection of individual items. Is that desirable? + - group: merge deactivation/activation within same group (fwd WasEdited flag). (#2550) + +!- color: the color conversion helpers/types are a mess and needs sorting out. + - color: (api breaking) ImGui::ColorConvertXXX functions should be loose ImColorConvertXX to match imgui_internals.h + + - plot: full featured plot/graph api w/ scrolling, zooming etc. all bell & whistle. why not! + - plot: PlotLines() should use the polygon-stroke facilities, less vertices (currently issues with averaging normals) + - plot: make it easier for user to draw extra stuff into the graph (e.g: draw basis, highlight certain points, 2d plots, multiple plots) + - plot: "smooth" automatic scale over time, user give an input 0.0(full user scale) 1.0(full derived from value) + - plot: option/feature: draw the zero line + - plot: option/feature: draw grid, vertical markers + - plot: option/feature: draw unit + - plot: add a helper e.g. Plot(char* label, float value, float time_span=2.0f) that stores values and Plot them for you - probably another function name. and/or automatically allow to plot ANY displayed value (more reliance on stable ID) + + - clipper: ability to force display 1 item in the list would be convenient (for patterns where we need to set active id etc.) + - clipper: ability to disable the clipping through a simple flag/bool. + - clipper: ability to run without knowing full count in advance. + - clipper: horizontal clipping support. (#2580) + + - separator: expose flags (#759) + - separator: take indent into consideration (optional) + - separator: width, thickness, centering (#1643) + - splitter: formalize the splitter idiom into an official api (we want to handle n-way split) (#319) + + - dock: merge docking branch (#2109) + - dock: dock out from a collapsing header? would work nicely but need emitting window to keep submitting the code. + + - tabs: "there is currently a problem because TabItem() will try to submit their own tooltip after 0.50 second, and this will have the effect of making your tooltip flicker once." -> tooltip priority work + - tabs: close button tends to overlap unsaved-document star + - tabs: consider showing the star at the same spot as the close button, like VS Code does. + - tabs: make EndTabBar fail if users doesn't respect BeginTabBar return value, for consistency/future-proofing. + - tabs: persistent order/focus in BeginTabBar() api (#261, #351) + - tabs: TabItem could honor SetNextItemWidth()? + - tabs: explicit api (even if internal) to cleanly manipulate tab order. + - tabs: Mouse wheel over tab bar could scroll? (#2702) + + - image/image button: misalignment on padded/bordered button? + - image/image button: parameters are confusing, image() has tint_col,border_col whereas imagebutton() has bg_col/tint_col. Even thou they are different parameters ordering could be more consistent. can we fix that? + - image button: not taking an explicit id can be problematic. (#2464, #1390) + - button: provide a button that looks framed. (?) + - slider/drag: ctrl+click when format doesn't include a % character.. disable? display underlying value in default format? (see TempInputTextScalar) + - slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt() + - slider: initial absolute click is imprecise. change to relative movement slider (same as scrollbar). (#1946) + - slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate. + - slider: tint background based on value (e.g. v_min -> v_max, or use 0.0f either side of the sign) + - slider: relative dragging? + precision dragging + - slider: step option (#1183) + - slider: style: fill % of the bar instead of positioning a drag. + - knob: rotating knob widget (#942) + - drag float: support for reversed drags (min > max) (removed is_locked, also see fdc526e) + - drag float: up/down axis + - drag float: power != 0.0f with current value being outside the range keeps the value stuck. + - drag float: added leeway on edge (e.g. a few invisible steps past the clamp limits) + + - combo: use clipper: make it easier to disable clipper with a single flag. + - combo: flag for BeginCombo to not return true when unchanged (#1182) + - combo: a way/helper to customize the combo preview (#1658) + - combo/listbox: keyboard control. need InputText-like non-active focus + key handling. considering keyboard for custom listbox (pr #203) + - listbox: multiple selection. + - listbox: unselect option (#1208) + - listbox: make it easier/more natural to implement range-select (need some sort of info/ref about the last clicked/focused item that user can translate to an index?) (wip stash) + - listbox: user may want to initial scroll to focus on the one selected value? + - listbox: expose hovered item for a simplified ListBox api + - listbox: keyboard navigation. + - listbox: disable capturing mouse wheel if the listbox has no scrolling. (#1681) + - listbox: scrolling should track modified selection. + - listbox: future api should allow to enable horizontal scrolling (#2510) + +!- popups/menus: clarify usage of popups id, how MenuItem/Selectable closing parent popups affects the ID, etc. this is quite fishy needs improvement! (#331, #402) + - modals: make modal title bar blink when trying to click outside the modal + - modals: technically speaking, we could make Begin() with ImGuiWindowFlags_Modal work without involving popup. May help untangle a few things, as modals are more like regular windows than popups. + - popups: if the popup functions took explicit ImGuiID it would allow the user to manage the scope of those ID. (#331) + - popups: clicking outside (to close popup) and holding shouldn't drag window below. + - popups: add variant using global identifier similar to Begin/End (#402) + - popups: border options. richer api like BeginChild() perhaps? (#197) + - popups: flags could be reworked to allow both mouse buttons as index (0..5 and as flags using higher-bit) allowing to or them. + - popups/modals: although it is sometimes convenient that popups/modals lifetime is owned by imgui, we could also a bool-owned-by-user api as long as Begin() return value testing is enforced. + + - tooltip: drag and drop with tooltip near monitor edges lose/changes its last direction instead of locking one. The drag and drop tooltip should always follow without changing direction. + - tooltip: allow to set the width of a tooltip to allow TextWrapped() etc. while keeping the height automatic. + - tooltip: tooltips with delay timers? or general timer policy? (instantaneous vs timed): IsItemHovered() with timer + implicit aabb-id for items with no ID. (#1485) + - tooltip: drag tooltip hovering over source widget with IsItemHovered/SetTooltip flickers. + + - menus: menu bars inside modal windows are acting weird. + - status-bar: add a per-window status bar helper similar to what menu-bar does. + - shortcuts: local-style shortcut api, e.g. parse "&Save" + - shortcuts,menus: global-style shortcut api e.g. "Save (CTRL+S)" -> explicit flag for recursing into closed menu + - shortcuts: programmatically access shortcuts "Focus("&Save")) + - menus: menu-bar: main menu-bar could affect clamping of windows position (~ akin to modifying DisplayMin) + - menus: hovering from menu to menu on a menu-bar has 1 frame without any menu, which is a little annoying. ideally either 0 either longer. + - menus: could merge draw call in most cases (how about storing an optional aabb in ImDrawCmd to move the burden of merging in a single spot). + - menus: would be nice if the Selectable() supported horizontal alignment (must be given the equivalent of WorkRect.Max.x matching the position of the shortcut column) + + - tree node: add treenode/treepush int variants? not there because (void*) cast from int warns on some platforms/settings? + - tree node: try to apply scrolling at time of TreePop() if node was just opened and end of node is past scrolling limits? + - tree node / selectable render mismatch which is visible if you use them both next to each other (e.g. cf. property viewer) + - tree node: tweak color scheme to distinguish headers from selected tree node (#581) + - tree node: leaf/non-leaf highlight mismatch. + - tree node: flag to disable formatting and/or detect "%s" + - tree node/opt: could avoid formatting when clipped (flag assuming we don't care about width/height, assume single line height? format only %s/%c to be able to count height?) + + - settings: write more decent code to allow saving/loading new fields: columns, selected tree nodes? + - settings: api for per-tool simple persistent data (bool,int,float,columns sizes,etc.) in .ini file (#437) + - settings/persistence: helpers to make TreeNodeBehavior persist (even during dev!) - may need to store some semantic and/or data type in ImGuiStoragePair + + - style: better default styles. (#707) + - style: PushStyleVar: allow direct access to individual float X/Y elements. + - style: add a highlighted text color (for headers, etc.) + - style: border types: out-screen, in-screen, etc. (#447) + - style: add window shadow (fading away from the window. Paint-style calculation of vertices alpha after drawlist would be easier) + - style: a concept of "compact style" that the end-user can easily rely on (e.g. PushStyleCompact()?) that maps to other settings? avoid implementing duplicate helpers such as SmallCheckbox(), etc. + - style: try to make PushStyleVar() more robust to incorrect parameters (to be more friendly to edit & continues situation). + - style: global scale setting. + - style: FramePadding could be different for up vs down (#584) + - style: WindowPadding needs to be EVEN as the 0.5 multiplier used on this value probably have a subtle effect on clip rectangle + - style: have a more global HSV setter (e.g. alter hue on all elements). consider replacing active/hovered by offset in HSV space? (#438, #707, #1223) + - style: gradients fill (#1223) ~ 2 bg colors for each fill? tricky with rounded shapes and using textures for corners. + - style editor: color child window height expressed in multiple of line height. + + - log: improve logging of ArrowButton, ListBox, TabItem + - log: carry on indent / tree depth when opening a child window + - log: enabling log ends up pushing and growing vertices buffers because we don't distinguish layout vs render clipping + - log: have more control over the log scope (e.g. stop logging when leaving current tree node scope) + - log: be able to log anything (e.g. right-click on a window/tree-node, shows context menu? log into tty/file/clipboard) + - log: let user copy any window content to clipboard easily (CTRL+C on windows? while moving it? context menu?). code is commented because it fails with multiple Begin/End pairs. + - log: obsolete LogButtons() all together. + - log: LogButtons() options for specifying depth and/or hiding depth slider + + - filters: set a current filter that tree node can automatically query to hide themselves + - filters: handle wild-cards (with implicit leading/trailing *), reg-exprs + - filters: fuzzy matches (may use code at blog.forrestthewoods.com/4cffeed33fdb) + + - drag and drop: fix/support/options for overlapping drag sources. + - drag and drop: focus drag target window on hold (even without open) + - drag and drop: releasing a drop shows the "..." tooltip for one frame - since e13e598 (#1725) + - drag and drop: drag source on a group object (would need e.g. an invisible button covering group in EndGroup) https://twitter.com/paniq/status/1121446364909535233 + - drag and drop: have some way to know when a drag begin from BeginDragDropSource() pov. (see 2018/01/11 post in #143) + - drag and drop: allow preview tooltip to be submitted from a different place than the drag source. (#1725) + - drag and drop: allow using with other mouse buttons (where activeid won't be set). (#1637) + - drag and drop: make it easier and provide a demo to have tooltip both are source and target site, with a more detailed one on target site (tooltip ordering problem) + - drag and drop: demo with reordering nodes (in a list, or a tree node). (#143) + - drag and drop: test integrating with os drag and drop (make it easy to do a naive WM_DROPFILE integration) + - drag and drop: allow for multiple payload types. (#143) + - drag and drop: make payload optional? payload promise? (see 2018/01/11 post in #143) + - drag and drop: (#143) "both an in-process pointer and a promise to generate a serialized version, for whether the drag ends inside or outside the same process" + - drag and drop: feedback when hovering a region blocked by modal (mouse cursor "NO"?) + + - node/graph editors (#306) (also see https://github.com/ocornut/imgui/wiki#node-editors) + - pie menus patterns (#434) + - markup: simple markup language for color change? (#902) + + - text: selectable text (for copy) as a generic feature (ItemFlags?) + - text: proper alignment options in imgui_internal.h + - text: it's currently impossible to have a window title with "##". perhaps an official workaround would be nice. \ style inhibitor? non-visible ascii code to insert between #? + - text: provided a framed text helper, e.g. https://pastebin.com/1Laxy8bT + - text: refactor TextUnformatted (or underlying function) to more explicitly request if we need width measurement or not + - text/layout/tabs: \t pulling position from base pos + step, or offset array (e.g. could be used in text edit, menus for simple icon+text alignment, etc.) + - text link/url button: underlined. should api expose an ID or use text contents as ID? which colors enum to use? + - text/wrapped: should be a more first-class citizen, e.g. wrapped text within a Selectable with known width. + - text/wrapped: custom separator for text wrapping. (#3002) + - text/wrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (#249) + + - font: arbitrary line spacing. (#2945) + - font: MergeMode: flags to select overwriting or not (this is now very easy with refactored ImFontAtlasBuildWithStbTruetype) + - font: free the Alpha buffer if user only requested RGBA. +!- font: better CalcTextSizeA() API, at least for simple use cases. current one is horrible (perhaps have simple vs extended versions). + - font: for the purpose of RenderTextEllipsis(), it might be useful that CalcTextSizeA() can ignore the trailing padding? + - font: a CalcTextHeight() helper could run faster than CalcTextSize().y + - font: enforce monospace through ImFontConfig (for icons?) + create dual ImFont output from same input, reusing rasterized data but with different glyphs/AdvanceX + - font: finish CustomRectRegister() to allow mapping Unicode codepoint to custom texture data + - font: remove ID from CustomRect registration, it seems unnecessary! + - font: make it easier to submit own bitmap font (same texture, another texture?). (#2127, #2575) + - font: PushFontSize API (#1018) + - font: MemoryTTF taking ownership confusing/not obvious, maybe default should be opposite? + - font: storing MinAdvanceX per font would allow us to skip calculating line width (under a threshold of character count) in loops looking for block width + - font/demo: add tools to show glyphs used by a text blob, display U16 value, list missing glyphs. + - font/demo: demonstrate use of ImFontGlyphRangesBuilder. + - font/atlas: add a missing Glyphs.reserve() + - font/atlas: incremental updates + - font/atlas: dynamic font atlas to avoid baking huge ranges into bitmap and make scaling easier. + - font/draw: vertical and/or rotated text renderer (#705) - vertical is easier clipping wise + - font/draw: need to be able to specify wrap start position. + - font/draw: better reserve policy for large horizontal block of text (shouldn't reserve for all clipped lines). also see #3349. + - font/draw: fix for drawing 16k+ visible characters in same call. + - font/draw: underline, squiggle line rendering helpers. + - font: optimization: for monospace font (like the default one) we can trim IndexXAdvance as long as trailing value is == FallbackXAdvance (need to make sure TAB is still correct), would save on cache line. + - font: add support for kerning, probably optional. A) perhaps default to (32..128)^2 matrix ~ 9K entries = 36KB, then hash for non-ascii?. B) or sparse lookup into per-char list? + - font: add a simpler CalcTextSizeA() api? current one ok but not welcome if user needs to call it directly (without going through ImGui::CalcTextSize) + - font: fix AddRemapChar() to work before atlas has been built. + - font: support for unicode codepoints higher than 0xFFFF? (pr #2815) + - font: (api breaking) remove "TTF" from symbol names. also because it now supports OTF. + - font/opt: Considering storing standalone AdvanceX table as 16-bit fixed point integer? + - font/opt: Glyph currently 40 bytes (2+9*4).

The UI can be highly dynamic, there are no construction + or destruction steps, less superfluous data retention on your side, less state duplication, less state synchronization, less bugs. + - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features. + - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build. + - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori). + You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in the FAQ. + - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances. + For every application frame your UI code will be called only once. This is in contrast to e.g. Unity's own implementation of an IMGUI, + where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches. + - Our origin are on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right. + - This codebase is also optimized to yield decent performances with typical "Debug" builds settings. + - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected). + If you get an assert, read the messages and comments around the assert. + - C++: this is a very C-ish codebase: we don't rely on C++11, we don't include any C++ headers, and ImGui:: is a namespace. + - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types. + See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that. + However, imgui_internal.h can optionally export math operators for ImVec2/ImVec4, which we use in this codebase. + - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction (avoid using it in your code!). + + + HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI + ---------------------------------------------- + - Overwrite all the sources files except for imconfig.h (if you have made modification to your copy of imconfig.h) + - Or maintain your own branch where you have imconfig.h modified as a top-most commit which you can regularly rebase over master. + - You can also use '#define IMGUI_USER_CONFIG "my_config_file.h" to redirect configuration to your own file. + - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes. + If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed + from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will + likely be a comment about it. Please report any issue to the GitHub page! + - To find out usage of old API, you can add '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' in your configuration file. + - Try to keep your copy of Dear ImGui reasonably up to date. + + + GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE + --------------------------------------------------------------- + - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library. + - In the majority of cases you should be able to use unmodified backends files available in the backends/ folder. + - Add the Dear ImGui source files + selected backend source files to your projects or using your preferred build system. + It is recommended you build and statically link the .cpp files as part of your project and NOT as shared library (DLL). + - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types. + - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them. + - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide. + Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render" + phases of your own application.

For more advanced uses, you may want to read from: + - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set. + - io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used). + - or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions. + Please reach out if you think the game vs navigation input sharing could be improved. + - Gamepad: + - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable. + - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + fill the io.NavInputs[] fields before calling NewFrame(). + Note that io.NavInputs[] is cleared by EndFrame(). + - See 'enum ImGuiNavInput_' in imgui.h for a description of inputs. For each entry of io.NavInputs[], set the following values: + 0.0f= not held. 1.0f= fully held. Pass intermediate 0.0f..1.0f values for analog triggers/sticks. + - We uses a simple >0.0f test for activation testing, and won't attempt to test for a dead-zone. + Your code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.). + - You can download PNG/PSD files depicting the gamepad controls for common controllers at: http://dearimgui.org/controls_sheets + - If you need to share inputs between your game and the imgui parts, the easiest approach is to go all-or-nothing, with a buttons combo + to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved. + - Mouse: + - PS4 users: Consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback. + - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + uSynergy.c (on your console/tablet/phone app) to share your PC mouse/keyboard. + - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag. + Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs dear imgui to move your mouse cursor along with navigation movements. + When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved. + When that happens your backend NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the backends in examples/ do that. + (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, imgui will misbehave as it will see your mouse as moving back and forth!) + (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want + to set a boolean to ignore your other external mouse positions until the external source is moved again.) + + + API BREAKING CHANGES + ==================== + + Occasionally introducing changes that are breaking the API. We try to make the breakage minor and easy to fix. + Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code. + When you are not sure about a old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files. + You can read releases logs https://github.com/ocornut/imgui/releases for more details. + + - 2021/02/03 (1.81) - renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox(). Kept inline redirection function (will obsolete). + - removed ListBoxHeader(const char* label, int items_count, int height_in_items = -1) in favor of specifying size. Kept inline redirection function (will obsolete). + - renamed ListBoxFooter() to EndListBox(). Kept inline redirection function (will obsolete). + - 2021/01/26 (1.81) - removed ImGuiFreeType::BuildFontAtlas(). Kept inline redirection function. Prefer using '#define IMGUI_ENABLE_FREETYPE', but there's a runtime selection path available too. The shared extra flags parameters (very rarely used) are now stored in ImFontAtlas::FontBuilderFlags. + - renamed ImFontConfig::RasterizerFlags (used by FreeType) to ImFontConfig::FontBuilderFlags. + - renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API. + - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.63 (August 2018): + - ImGui::IsItemDeactivatedAfterChange() -> use ImGui::IsItemDeactivatedAfterEdit(). + - ImGuiCol_ModalWindowDarkening -> use ImGuiCol_ModalWindowDimBg + - ImGuiInputTextCallback -> use ImGuiTextEditCallback + - ImGuiInputTextCallbackData -> use ImGuiTextEditCallbackData + - 2020/12/21 (1.80) - renamed ImDrawList::AddBezierCurve() to AddBezierCubic(), and PathBezierCurveTo() to PathBezierCubicCurveTo(). Kept inline redirection function (will obsolete). + - 2020/12/04 (1.80) - added imgui_tables.cpp file! Manually constructed project files will need the new file added! + - 2020/11/18 (1.80) - renamed undocumented/internals ImGuiColumnsFlags_* to ImGuiOldColumnFlags_* in prevision of incoming Tables API. + - 2020/11/03 (1.80) - renamed io.ConfigWindowsMemoryCompactTimer to io.ConfigMemoryCompactTimer as the feature will apply to other data structures + - 2020/10/14 (1.80) - backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/. + - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.60 (April 2018): + - io.RenderDrawListsFn pointer -> use ImGui::GetDrawData() value and call the render function of your backend + - ImGui::IsAnyWindowFocused() -> use ImGui::IsWindowFocused(ImGuiFocusedFlags_AnyWindow) + - ImGui::IsAnyWindowHovered() -> use ImGui::IsWindowHovered(ImGuiHoveredFlags_AnyWindow) + - ImGuiStyleVar_Count_ -> use ImGuiStyleVar_COUNT + - ImGuiMouseCursor_Count_ -> use ImGuiMouseCursor_COUNT + - removed redirecting functions names that were marked obsolete in 1.61 (May 2018): + - InputFloat (... int decimal_precision ...) -> use InputFloat (... const char* format ...) with format = "%.Xf" where X is your value for decimal_precision. + - same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter. + - 2020/10/05 (1.79) - removed ImGuiListClipper: Renamed constructor parameters which created an ambiguous alternative to using the ImGuiListClipper::Begin() function, with misleading edge cases (note: imgui_memory_editor <0.40 from imgui_club/ used this old clipper API. Update your copy if needed). + - 2020/09/25 (1.79) - renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete sooner because previous name was added recently). + - 2020/09/25 (1.79) - renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton. + - 2020/09/21 (1.79) - renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), reverting the change from 1.77. For varieties of reason this is more self-explanatory. + - 2020/09/21 (1.79) - removed return value from OpenPopupOnItemClick() - returned true on mouse release on item - because it is inconsistent with other popup APIs and makes others misleading. It's also and unnecessary: you can use IsWindowAppearing() after BeginPopup() for a similar result. + - 2020/09/17 (1.79) - removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font. If you scaled this value after calling AddFontDefault(), this is now done automatically. It was also getting in the way of better font scaling, so let's get rid of it now! + - 2020/08/17 (1.78) - obsoleted use of the trailing 'float power=1.0f' parameter for DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(), DragFloatRange2(), DragScalar(), DragScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(), SliderScalar(), SliderScalarN(), VSliderFloat() and VSliderScalar(). + replaced the 'float power=1.0f' argument with integer-based flags defaulting to 0 (as with all our flags). + worked out a backward-compatibility scheme so hopefully most C++ codebase should not be affected. in short, when calling those functions: + - if you omitted the 'power' parameter (likely!), you are not affected. + - if you set the 'power' parameter to 1.0f (same as previous default value): 1/ your compiler may warn on float>int conversion, 2/ everything else will work. 3/ you can replace the 1.0f value with 0 to fix the warning, and be technically correct. + - if you set the 'power' parameter to >1.0f (to enable non-linear editing): 1/ your compiler may warn on float>int conversion, 2/ code will assert at runtime, 3/ in case asserts are disabled, the code will not crash and enable the _Logarithmic flag. 4/ you can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert and get a _similar_ effect as previous uses of power >1.0f. + see https://github.com/ocornut/imgui/issues/3361 for all details. + kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar(). For those three the 'float power=1.0f' version were removed directly as they were most unlikely ever used. + for shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`. + - obsoleted use of v_min > v_max in DragInt, DragFloat, DragScalar to lock edits (introduced in 1.73, was not demoed nor documented very), will be replaced by a more generic ReadOnly feature. You may use the ImGuiSliderFlags_ReadOnly internal flag in the meantime. + - 2020/06/23 (1.77) - removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems. + - 2020/06/15 (1.77) - renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete). [NOTE: THIS WAS REVERTED IN 1.79] + - 2020/06/15 (1.77) - removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017. + - 2020/04/23 (1.77) - removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular(). + - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more. + - 2019/12/17 (1.75) - [undid this change in 1.76] made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead. + - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value. + - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017): + - ShowTestWindow() -> use ShowDemoWindow() + - IsRootWindowFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow) + - IsRootWindowOrAnyChildFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows) + - SetNextWindowContentWidth(w) -> use SetNextWindowContentSize(ImVec2(w, 0.0f) + - GetItemsLineHeightWithSpacing() -> use GetFrameHeightWithSpacing() + - ImGuiCol_ChildWindowBg -> use ImGuiCol_ChildBg + - ImGuiStyleVar_ChildWindowRounding -> use ImGuiStyleVar_ChildRounding + - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap + - IMGUI_DISABLE_TEST_WINDOWS -> use IMGUI_DISABLE_DEMO_WINDOWS + - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was the vaguely documented and rarely if ever used). Instead we added an explicit PrimUnreserve() API. + - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it). + - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency. + - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017): + - Begin() [old 5 args version] -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed + - IsRootWindowOrAnyChildHovered() -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows) + - AlignFirstTextHeightToWidgets() -> use AlignTextToFramePadding() + - SetNextWindowPosCenter() -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f) + - ImFont::Glyph -> use ImFontGlyph + - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function. + if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix. + The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay). + If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you. + - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete). + - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete). + - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71. + - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have + overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering. + This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows. + Please reach out if you are affected. + - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete). + - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c). + - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now. + - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete). + - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete). + - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete). + - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with an arbitrary small value! + - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already). + - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead! + - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete). + - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects. + - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags. + - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files. + - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete). + - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h. + If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths. + - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) + - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp. + NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED. + Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions. + - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent). + - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete). + - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly). + - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature. + - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency. + - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time. + - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete). + - 2018/06/08 (1.62) - examples: the imgui_impl_XXX files have been split to separate platform (Win32, GLFW, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan, etc.). + old backends will still work as is, however prefer using the separated backends as they will be updated to support multi-viewports. + when adopting new backends follow the main.cpp code of your preferred examples/ folder to know which functions to call. + in particular, note that old backends called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function. + - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set. + - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details. + - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more. + If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format. + To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code. + If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them. + - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format", + consistent with other functions. Kept redirection functions (will obsolete). + - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value. + - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some backend ahead of merging the Nav branch). + - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now. + - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. + - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums. + - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment. + - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display. + - 2018/02/07 (1.60) - reorganized context handling to be more explicit, + - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END. + - removed Shutdown() function, as DestroyContext() serve this purpose. + - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance. + - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts. + - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts. + - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths. + - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData. + - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side. + - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete). + - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags + - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame. + - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set. + - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete). + - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete). + - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete). + - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete). + - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete). + - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed. + - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up. + Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions. + - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency. + - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg. + - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding. + - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows); + - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency. + - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it. + - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details. + removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting. + IsItemHoveredRect() --> IsItemHovered(ImGuiHoveredFlags_RectOnly) + IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow) + IsMouseHoveringWindow() --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior] + - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead! + - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete). + - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete). + - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete). + - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your backend if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)". + - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)! + - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete). + - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete). + - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency. + - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix. + - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type. + - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely. + - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete). + - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete). + - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton(). + - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu. + - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options. + - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0, 0))' + - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse + - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset. + - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity. + - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetId() and use it instead of passing string to BeginChild(). + - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it. + - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc. + - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully breakage should be minimal. + - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore. + If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar. + This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color: + ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); } + If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color. + - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext(). + - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection. + - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen). + - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer. + - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref github issue #337). + - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337) + - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete). + - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert. + - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you. + - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. + - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete. + - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position. + GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side. + GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out! + - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize + - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project. + - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason + - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure. + you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text. + - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost. + this necessary change will break your rendering function! the fix should be very easy. sorry for that :( + - if you are using a vanilla copy of one of the imgui_impl_XXX.cpp provided in the example, you just need to update your copy and you can ignore the rest. + - the signature of the io.RenderDrawListsFn handler has changed! + old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count) + new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data). + parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount' + ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new. + ImDrawCmd: 'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'. + - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer. + - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering! + - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade! + - 2015/07/10 (1.43) - changed SameLine() parameters from int to float. + - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete). + - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount. + - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence + - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely be used. Sorry! + - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete). + - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete). + - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons. + - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened. + - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same). + - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50. + - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API + - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive. + - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead. + - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50. + - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing + - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused().

Otherwise, you may skip submitting the contents of a cell/column, BUT ONLY if you know +// it is not going to contribute to row height. +// In many situations, you may skip submitting contents for every columns but one (e.g. the first one). +// - Case A: column is not hidden by user, and at least partially in sight (most common case). +// - Case B: column is clipped / out of sight (because of scrolling or parent ClipRect): TableNextColumn() return false as a hint but we still allow layout output. +// - Case C: column is hidden explicitly by the user (e.g. via the context menu, or _DefaultHide column flag, etc.). +// +// [A] [B] [C] +// TableNextColumn(): true false false -> [userland] when TableNextColumn() / TableSetColumnIndex() return false, user can skip submitting items but only if the column doesn't contribute to row height. +// SkipItems: false false true -> [internal] when SkipItems is true, most widgets will early out if submitted, resulting is no layout output. +// ClipRect: normal zero-width zero-width -> [internal] when ClipRect is zero, ItemAdd() will return false and most widgets will early out mid-way. +// ImDrawList output: normal dummy dummy -> [internal] when using the dummy channel, ImDrawList submissions (if any) will be wasted (because cliprect is zero-width anyway). +// +// - We need distinguish those cases because non-hidden columns that are clipped outside of scrolling bounds should still contribute their height to the row. +// However, in the majority of cases, the contribution to row height is the same for all columns, or the tallest cells are known by the programmer. +//----------------------------------------------------------------------------- +// About clipping/culling of whole Tables: +// - Scrolling tables with a known outer size can be clipped earlier as BeginTable() will return false. +//----------------------------------------------------------------------------- + +//----------------------------------------------------------------------------- +// [SECTION] Header mess +//----------------------------------------------------------------------------- + +#if defined(_MSC_VER) && !defined(_CRT_SECURE_NO_WARNINGS) +#define _CRT_SECURE_NO_WARNINGS +#endif + +#include "imgui.h" +#ifndef IMGUI_DISABLE + +#ifndef IMGUI_DEFINE_MATH_OPERATORS +#define IMGUI_DEFINE_MATH_OPERATORS +#endif +#include "imgui_internal.h" + +// System includes +#if defined(_MSC_VER) && _MSC_VER <= 1500 // MSVC 2008 or earlier +#include <stddef.h> // intptr_t +#else +#include <stdint.h> // intptr_t +#endif + +// Visual Studio warnings +#ifdef _MSC_VER +#pragma warning (disable: 4127) // condition expression is constant +#pragma warning (disable: 4996) // 'This function or variable may be unsafe': strcpy, strdup, sprintf, vsnprintf, sscanf, fopen +#if defined(_MSC_VER) && _MSC_VER >= 1922 // MSVC 2019 16.2 or later +#pragma warning (disable: 5054) // operator '|': deprecated between enumerations of different types +#endif +#endif + +// Clang/GCC warnings with -Weverything +#if defined(__clang__) +#if __has_warning("-Wunknown-warning-option") +#pragma clang diagnostic ignored "-Wunknown-warning-option" // warning: unknown warning group 'xxx' // not all warnings are known by all Clang versions and they tend to be rename-happy.. so ignoring warnings triggers new warnings on some configuration.

In this mode, it declares a +// single public symbol, STB_TexteditState, which encapsulates the current +// state of a text widget (except for the string, which you will store +// separately). +// +// To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a +// primitive type that defines a single character (e.g. char, wchar_t, etc). +// +// To save space or increase undo-ability, you can optionally define the +// following things that are used by the undo system: +// +// STB_TEXTEDIT_POSITIONTYPE small int type encoding a valid cursor position +// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow +// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer +// +// If you don't define these, they are set to permissive types and +// moderate sizes. The undo system does no memory allocations, so +// it grows STB_TexteditState by the worst-case storage which is (in bytes): +// +// [4 + 3 * sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATE_COUNT +// + sizeof(STB_TEXTEDIT_CHARTYPE) * STB_TEXTEDIT_UNDOCHAR_COUNT +// +// +// Implementation mode: +// +// If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it +// will compile the implementation of the text edit widget, depending +// on a large number of symbols which must be defined before the include. +// +// The implementation is defined only as static functions. You will then +// need to provide your own APIs in the same file which will access the +// static functions. +// +// The basic concept is that you provide a "string" object which +// behaves like an array of characters. stb_textedit uses indices to +// refer to positions in the string, implicitly representing positions +// in the displayed textedit. This is true for both plain text and +// rich text; even with rich text stb_truetype interacts with your +// code as if there was an array of all the displayed characters. +// +// Symbols that must be the same in header-file and implementation mode: +// +// STB_TEXTEDIT_CHARTYPE the character type +// STB_TEXTEDIT_POSITIONTYPE small type that is a valid cursor position +// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow +// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer +// +// Symbols you must define for implementation mode: +// +// STB_TEXTEDIT_STRING the type of object representing a string being edited, +// typically this is a wrapper object with other data you need +// +// STB_TEXTEDIT_STRINGLEN(obj) the length of the string (ideally O(1)) +// STB_TEXTEDIT_LAYOUTROW(&r,obj,n) returns the results of laying out a line of characters +// starting from character #n (see discussion below) +// STB_TEXTEDIT_GETWIDTH(obj,n,i) returns the pixel delta from the xpos of the i'th character +// to the xpos of the i+1'th char for a line of characters +// starting at character #n (i.e. accounts for kerning +// with previous char) +// STB_TEXTEDIT_KEYTOTEXT(k) maps a keyboard input to an insertable character +// (return type is int, -1 means not valid to insert) +// STB_TEXTEDIT_GETCHAR(obj,i) returns the i'th character of obj, 0-based +// STB_TEXTEDIT_NEWLINE the character returned by _GETCHAR() we recognize +// as manually wordwrapping for end-of-line positioning +// +// STB_TEXTEDIT_DELETECHARS(obj,i,n) delete n characters starting at i +// STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n) insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*) +// +// STB_TEXTEDIT_K_SHIFT a power of two that is or'd in to a keyboard input to represent the shift key +// +// STB_TEXTEDIT_K_LEFT keyboard input to move cursor left +// STB_TEXTEDIT_K_RIGHT keyboard input to move cursor right +// STB_TEXTEDIT_K_UP keyboard input to move cursor up +// STB_TEXTEDIT_K_DOWN keyboard input to move cursor down +// STB_TEXTEDIT_K_PGUP keyboard input to move cursor up a page +// STB_TEXTEDIT_K_PGDOWN keyboard input to move cursor down a page +// STB_TEXTEDIT_K_LINESTART keyboard input to move cursor to start of line // e.g. HOME +// STB_TEXTEDIT_K_LINEEND keyboard input to move cursor to end of line // e.g. END +// STB_TEXTEDIT_K_TEXTSTART keyboard input to move cursor to start of text // e.g. ctrl-HOME +// STB_TEXTEDIT_K_TEXTEND keyboard input to move cursor to end of text // e.g. ctrl-END +// STB_TEXTEDIT_K_DELETE keyboard input to delete selection or character under cursor +// STB_TEXTEDIT_K_BACKSPACE keyboard input to delete selection or character left of cursor +// STB_TEXTEDIT_K_UNDO keyboard input to perform undo +// STB_TEXTEDIT_K_REDO keyboard input to perform redo +// +// Optional: +// STB_TEXTEDIT_K_INSERT keyboard input to toggle insert mode +// STB_TEXTEDIT_IS_SPACE(ch) true if character is whitespace (e.g. 'isspace'), +// required for default WORDLEFT/WORDRIGHT handlers +// STB_TEXTEDIT_MOVEWORDLEFT(obj,i) custom handler for WORDLEFT, returns index to move cursor to +// STB_TEXTEDIT_MOVEWORDRIGHT(obj,i) custom handler for WORDRIGHT, returns index to move cursor to +// STB_TEXTEDIT_K_WORDLEFT keyboard input to move cursor left one word // e.g. ctrl-LEFT +// STB_TEXTEDIT_K_WORDRIGHT keyboard input to move cursor right one word // e.g. ctrl-RIGHT +// STB_TEXTEDIT_K_LINESTART2 secondary keyboard input to move cursor to start of line +// STB_TEXTEDIT_K_LINEEND2 secondary keyboard input to move cursor to end of line +// STB_TEXTEDIT_K_TEXTSTART2 secondary keyboard input to move cursor to start of text +// STB_TEXTEDIT_K_TEXTEND2 secondary keyboard input to move cursor to end of text +// +// Keyboard input must be encoded as a single integer value; e.g. a character code +// and some bitflags that represent shift states. to simplify the interface, SHIFT must +// be a bitflag, so we can test the shifted state of cursor movements to allow selection, +// i.e. (STB_TEXTEDIT_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow. +// +// You can encode other things, such as CONTROL or ALT, in additional bits, and +// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. For example, +// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN +// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit, +// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the +// API below. The control keys will only match WM_KEYDOWN events because of the +// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN +// bit so it only decodes WM_CHAR events. +// +// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed +// row of characters assuming they start on the i'th character--the width and +// the height and the number of characters consumed. This allows this library +// to traverse the entire layout incrementally. You need to compute word-wrapping +// here. +// +// Each textfield keeps its own insert mode state, which is not how normal +// applications work.

STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to +// anything other type you wante before including. +// +// +// When rendering, you can read the cursor position and selection state from +// the STB_TexteditState. +// +// +// Notes: +// +// This is designed to be usable in IMGUI, so it allows for the possibility of +// running in an IMGUI that has NOT cached the multi-line layout. For this +// reason, it provides an interface that is compatible with computing the +// layout incrementally--we try to make sure we make as few passes through +// as possible. (For example, to locate the mouse pointer in the text, we +// could define functions that return the X and Y positions of characters +// and binary search Y and then X, but if we're doing dynamic layout this +// will run the layout algorithm many times, so instead we manually search +// forward in one pass. Similar logic applies to e.g. up-arrow and +// down-arrow movement.) +// +// If it's run in a widget that *has* cached the layout, then this is less +// efficient, but it's not horrible on modern computers. But you wouldn't +// want to edit million-line files with it. + + +//////////////////////////////////////////////////////////////////////////// +//////////////////////////////////////////////////////////////////////////// +//// +//// Header-file mode +//// +//// + +#ifndef INCLUDE_STB_TEXTEDIT_H +#define INCLUDE_STB_TEXTEDIT_H + +//////////////////////////////////////////////////////////////////////// +// +// STB_TexteditState +// +// Definition of STB_TexteditState which you should store +// per-textfield;

The new rasterizer more +// accurately measures pixel coverage for anti-aliasing, except in the case +// where multiple shapes overlap, in which case it overestimates the AA pixel +// coverage. Thus, anti-aliasing of intersecting shapes may look wrong. If +// this turns out to be a problem, you can re-enable the old rasterizer with +// #define STBTT_RASTERIZER_VERSION 1 +// which will incur about a 15% speed hit. +// +// ADDITIONAL DOCUMENTATION +// +// Immediately after this block comment are a series of sample programs. +// +// After the sample programs is the "header file" section. This section +// includes documentation for each API function. +// +// Some important concepts to understand to use this library: +// +// Codepoint +// Characters are defined by unicode codepoints, e.g. 65 is +// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is +// the hiragana for "ma". +// +// Glyph +// A visual character shape (every codepoint is rendered as +// some glyph) +// +// Glyph index +// A font-specific integer ID representing a glyph +// +// Baseline +// Glyph shapes are defined relative to a baseline, which is the +// bottom of uppercase characters. Characters extend both above +// and below the baseline. +// +// Current Point +// As you draw text to the screen, you keep track of a "current point" +// which is the origin of each character. The current point's vertical +// position is the baseline. Even "baked fonts" use this model. +// +// Vertical Font Metrics +// The vertical qualities of the font, used to vertically position +// and space the characters. See docs for stbtt_GetFontVMetrics. +// +// Font Size in Pixels or Points +// The preferred interface for specifying font sizes in stb_truetype +// is to specify how tall the font's vertical extent should be in pixels. +// If that sounds good enough, skip the next paragraph. +// +// Most font APIs instead use "points", which are a common typographic +// measurement for describing font size, defined as 72 points per inch. +// stb_truetype provides a point API for compatibility. However, true +// "per inch" conventions don't make much sense on computer displays +// since different monitors have different number of pixels per +// inch. For example, Windows traditionally uses a convention that +// there are 96 pixels per inch, thus making 'inch' measurements have +// nothing to do with inches, and thus effectively defining a point to +// be 1.333 pixels. Additionally, the TrueType font data provides +// an explicit scale factor to scale a given font's glyphs to points, +// but the author has observed that this scale factor is often wrong +// for non-commercial fonts, thus making fonts scaled in points +// according to the TrueType spec incoherently sized in practice. +// +// DETAILED USAGE: +// +// Scale: +// Select how high you want the font to be, in points or pixels. +// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute +// a scale factor SF that will be used by all other functions. +// +// Baseline: +// You need to select a y-coordinate that is the baseline of where +// your text will appear. Call GetFontBoundingBox to get the baseline-relative +// bounding box for all characters. SF*-y0 will be the distance in pixels +// that the worst-case character could extend above the baseline, so if +// you want the top edge of characters to appear at the top of the +// screen where y=0, then you would set the baseline to SF*-y0. +// +// Current point: +// Set the current point where the first character will appear. The +// first character could extend left of the current point; this is font +// dependent. You can either choose a current point that is the leftmost +// point and hope, or add some padding, or check the bounding box or +// left-side-bearing of the first character to be displayed and set +// the current point based on that. +// +// Displaying a character: +// Compute the bounding box of the character. It will contain signed values +// relative to <current_point, baseline>. I.e. if it returns x0,y0,x1,y1, +// then the character should be displayed in the rectangle from +// <current_point+SF*x0, baseline+SF*y0> to <current_point+SF*x1,baseline+SF*y1). +// +// Advancing for the next character: +// Call GlyphHMetrics, and compute 'current_point += SF * advance'. +// +// +// ADVANCED USAGE +// +// Quality: +// +// - Use the functions with Subpixel at the end to allow your characters +// to have subpixel positioning. Since the font is anti-aliased, not +// hinted, this is very import for quality. (This is not possible with +// baked fonts.) +// +// - Kerning is now supported, and if you're supporting subpixel rendering +// then kerning is worth using to give your text a polished look. +// +// Performance: +// +// - Convert Unicode codepoints to glyph indexes and operate on the glyphs; +// if you don't do this, stb_truetype is forced to do the conversion on +// every call. +// +// - There are a lot of memory allocations. We should modify it to take +// a temp buffer and allocate from the temp buffer (without freeing), +// should help performance a lot. +// +// NOTES +// +// The system uses the raw data found in the .ttf file without changing it +// and without building auxiliary data structures. This is a bit inefficient +// on little-endian systems (the data is big-endian), but assuming you're +// caching the bitmaps or glyph shapes this shouldn't be a big deal. +// +// It appears to be very hard to programmatically determine what font a +// given file is in a general way.
