Using silx widgets in Qt Designer
=================================
With PyQt_, it is possible to use ``silx.gui`` widgets (and widgets written with PyQt in general) from the `Qt Designer`_.
The following ``silx.gui`` widgets are available in the Qt Designer:
- :class:`silx.gui.plot.Plot1D`
- :class:`silx.gui.plot.Plot2D`
- :class:`silx.gui.plot.PlotWidget`
- :class:`silx.gui.plot.PlotWindow`
Pre-requisite
-------------
The following software must be installed:
- Qt_ with the `Qt Designer`_.
- Python_.
- PyQt_ with the designer plugin.
- The ``silx`` Python package and its dependencies.
:mod:`silx.gui.plot` widgets requires matplotlib_.
Usage
-----
The **PYQTDESIGNERPATH** environment variable defines the search paths for plugins enabling use of PyQt widgets in the designer.
To start the Qt Designer with ``silx.gui`` widgets available, on Linux, run the following from the command line::
PYQTDESIGNERPATH=<silx_designer_plugin_dir> designer
See `Using Qt Designer <http://pyqt.sourceforge.net/Docs/PyQt5/designer.html>`_ in PyQt_ documentation.
