gtk:tool-item-proxy-menu-item (item id)

item -- a gtk:tool-item widget
id -- a string used to identify the menu item
menuitem -- a gtk:menu-item to be used in the overflow menu

Accessor of the proxy menu item of the tool item. The gtk:tool-item-proxy-menu-item function gets the menu item used in the toolbar overflow menu. The (setf gtk:tool-item-proxy-menu-item) function sets the menu item used in the toolbar overflow menu.

Custom subclasses of the gtk:tool-item class should use this function to update their menu item when the gtk:tool-item changes. That the id argument must match ensures that a gtk:tool-item widget will not inadvertently change a menu item that they did not create.
