+ * @Short_description: A menu item used to tear off and reattach its menu
+ * @Title: GtkTearoffMenuItem
+ * @See_also: #GtkMenu
+ *
+ * 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.
+ *
+ * <note>#GtkTearoffMenuItem is deprecated and should not be used in newly
+ * written code. Menus are not meant to be torn around.</note>
