Constructor Detail


public Portalchildren()
Method Detail


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.

public void invalidate()
Description copied from interface: Component
Invalidates this component by setting the dirty flag such that it will be redraw the whole content of this component and its dependences later. And, the widget associated with this component and all its descendant at the client will be deleted and recreated, too.

If the application is totally controlled by the server side (i.e., you don't write client codes), you rarely need to access this method.

It can be called only in the request-processing and event-processing phases. However, it is NOT allowed in the rendering phase.

public void beforeParentChanged(Component parent)
Description copied from class: AbstractComponent
Default: does nothing.

Specified by:
beforeParentChanged in interface ComponentCtrl
beforeParentChanged in class AbstractComponent
parent - the new parent. If null, it means detachment.

public void beforeChildAdded(Component child,
                             Component refChild)
Description copied from class: AbstractComponent
Default: does nothing.

Specified by:
beforeChildAdded in interface ComponentCtrl
beforeChildAdded in class AbstractComponent
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.

ComponentCtrl.beforeChildAdded(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component)
