Description A GtkTearoffMenuItem is a special GtkMenuItem which is used to tear off and reattach its menu. When its menu is shown normally, the GtkTearoffMenuItem is drawn as a dotted line indicating that the menu can be torn off. Activating it causes its menu to be torn off and displayed in its own window as a tearoff menu. When its menu is shown as a tearoff menu, the GtkTearoffMenuItem is drawn as a dotted line which has a left pointing arrow graphic indicating that the tearoff menu can be reattached. Activating it will erase the tearoff menu window.
