gtkWidgetSetWindow
Sets a widget's window. This function should only be used in a
widget's GtkWidget::realize() implementation. The window passed is
usually either new window created with gdkWindowNew, or the
window of its parent widget as returned by
gtkWidgetGetParentWindow.
gtkWidgetSetWindow(object, window)
Widgets must indicate whether they will create their own GdkWindow
by calling gtkWidgetSetHasWindow. This is usually done in the
widget's init() function.
