Widget.isComposited

Whether @widget can rely on having its alpha channel drawn correctly. On X11 this function returns whether a compositing manager is running for @widget’s screen.

Please note that the semantics of this call will change in the future if used on a widget that has a composited window in its hierarchy (as set by gdk_window_set_composited()).

Return: %TRUE if the widget can rely on its alpha channel being drawn correctly.
