public class MenuItem extends ListGridRecord implements HasClickHandlers
Menu
. Each MenuItem
can have a
title
, icon
, shortcut\n keys
, optional submenu
and various other
settings.
To create a Menu, create a series of MenuItems and call Menu.setItems()
.
Alternatively, Menus support binding to a DataSource
.
As another option, here's a sample of a Menu in Component XML
:
<Menu> <items> <MenuItem title="item1" click="alert(1)"/> <MenuItem title="item2"/> </items> </Menu>
