fltk::Menu | +----fltk::ItemGroup
#include <fltk/ItemGroup.h>
If this widget is told to draw, it draws just like fltk::Item draws. See that for more details. The triangle indicating a submenu is not drawn by this, it is drawn by the parent menu.
Because this is an fltk::Menu subclass, you can also call popup() and add() and other methods to manipulate the items inside it.
In a browser, the value() indicates if the widget is open or not. In a multi-browser, the selected() indicates if the widget is currently selected.
