GdkWindow* gtk_widget_get_root_window ( GtkWidget* widget )
Get the root window where this widget is located. This function can
only be called after the widget has been added to a widget
GtkWindow at the top.
The root window is useful for such purposes as creating a popup
GdkWindow associated with the window. In general, you should only
create display specific resources when a widget has been realized,
and you should free those resources when the widget is unrealized.
