*
* A menu is a list of items displayed above its parent. When the menu is
* showing its parent is darkened. Each item can have a sub-menu. The menu
* object can be used to display a menu on a right click event, in a toolbar,
* anywhere.
*
* Signals that you can add callbacks for are:
* @li "clicked" - the user clicked the empty space in the menu to dismiss.
*
* Default content parts of the menu items that you can use for are:
* @li "default" - A main content of the menu item
*
* Default text parts of the menu items that you can use for are:
* @li "default" - label in the menu item
*
* Supported elm_object_item common APIs.
