The
gtk:tearoff-menu-item widget is a special
gtk:menu-item
widget which is used to tear off and reattach its menu.
When its menu is shown normally, the tearoff menu 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 tearoff menu 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.
Warning
The
gtk:tearoff-menu-item widget is deprecated since GTK 3.4 and
should not be used in newly written code. Menus are not meant to be torn
around.
