GDK_EXPOSE GtkWidget::expose_event
-gtk_widget_ref() vs. gtk_object_ref()
--------------------------------------
-
-The widget referencing functions gtk_widget_ref() and gtk_widget_unref()
-are currently just wrappers about the corresponding referencing functions
-for objects. Still you should use the widget referencing functions if you
-are sure the referenced object is of type GTK_WIDGET_TYPE.
