Class Menupopup

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, org.zkoss.zk.ui.Component, org.zkoss.zk.ui.ext.Scope, org.zkoss.zk.ui.sys.ComponentCtrl
    public class Menupopup
extends Popup
    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 getZclass(): z-menupopup. (since 3.5.0)
