Menupopup

• Demonstration: Menu
• Java API: Menupopup
• JavaScript API: Menupopup

Employment/Purpose

A container used to display menus. It should be placed inside a Menu.

Supported event: onOpen.

Note: to have better performance, onOpen is sent only if non-deferrable event listener is registered (see Deferrable).

To load the content dynamically, you can listen to the onOpen event, and then create menuitem when OpenEvent.isOpen() is true.

Default HtmlBasedComponent.getSclass(): menupopup.

<menubar id="menubar">
	<menu label="File">

			<menuitem label="New" onClick="alert(self.label)" />
