Widget.setHasWindow

Specifies whether widget has a GdkWindow of its own. Note that all realized widgets have a non-NULL "window" pointer (gtk_widget_get_window() never returns a NULL window when a widget is realized), but for many of them it's actually the GdkWindow of one of its parent widgets. Widgets that do not create a window for themselves in GtkWidget::realize() must announce this by calling this function with has_window = FALSE. This function should only be called by widget implementations, and they should call it in their init() function. Since 2.18
