public class AdapterMenuItem
extends Item

Allows any widget to be placed in a menu. As of 2.0, any widget can be added directly to a Menu therefore reducing the need for this class. AdapterMenuItem allows arbitrary widgets to be added to Menu and also configured as Items.

For example, when adding a ComboBox to a Menu, the Menu will be closed when a item from the combo drop down list is clicked if the combo is added directly to the Menu. To stop the menu from being closed, an AdapterMenuItem can be used so that @link Item.setHideOnClick(boolean) can be called.
