if the application will paint on the widgetGtkEventBox
and GtkWindow
,
the effect is to suppress default themed drawing of the widget's
background. (Children of the widget will still be drawn.) The application
is then entirely responsible for drawing the widget background.
Note that the background is still drawn when the widget is mapped.
If this is not suitable (e.g. because you want to make a transparent
window using an RGBA visual), you can work around this by doing:
window$realize() window$window$setBackPixmap(NULL, FALSE) window$show()
