This widget is set by calling + * gtk_accel_label_set_accel_widget(). + * + * For example, a #GtkMenuItem widget may have an accelerator added to emit the + * "activate" signal when the 'Ctl+S' key combination is pressed. + * A #GtkAccelLabel is created and added to the #GtkMenuItem, and + * gtk_accel_label_set_accel_widget() is called with the #GtkMenuItem as the + * second argument.
