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)

Method Detail

getZclass

public java.lang.String getZclass()

Description copied from class: HtmlBasedComponent

Returns the ZK Cascading Style class(es) for this component. It usually depends on the implementation of the mold (AbstractComponent.getMold()).

Default: null (the default value depends on element).

HtmlBasedComponent.setZclass(java.lang.String)) will completely replace the default style of a component. In other words, the default style of a component is associated with the default value of HtmlBasedComponent.getZclass(). Once it is changed, the default style won't be applied at all. If you want to perform small adjustments, use HtmlBasedComponent.setSclass(java.lang.String) instead.

Overrides:

getZclass in class Popup

HtmlBasedComponent.getSclass()

beforeChildAdded

public void beforeChildAdded(Component child,
                             Component refChild)

Description copied from class: AbstractComponent

Default: does nothing.

Specified by:

beforeChildAdded in interface ComponentCtrl

Overrides:

beforeChildAdded in class AbstractComponent

Parameters:

child - the child to be added (never null).

refChild - another child component that the new child will be inserted before it. If null, the new child will be the last child.
