/**
\class Fl_File_Input
\brief This widget displays a pathname in a text input field.
A navigation bar located above the input field allows the user to
navigate upward in the directory tree.
You may want to handle FL_WHEN_CHANGED events for tracking text changes
and also FL_WHEN_RELEASE for button release when changing to parent dir.
FL_WHEN_RELEASE callback won't be called if the directory clicked
is the same that the current one.

\note As all Fl_Input derived objects, Fl_File_Input may call its callback
when loosing focus (see FL_UNFOCUS) to update its state like its cursor shape.
One resulting side effect is that you should call clear_changed() early in your callback
to avoid reentrant calls if you plan to show another window or dialog box in the callback.
