Examples of org.zkoss.zul.ListitemRenderer

org.zkoss.zul.ListitemRenderer
Identifies components that can be used as "rubber stamps" to paint the cells in a {@link Listbox}.
If you need better control, your renderer can also implement {@link ListitemRendererExt}. If you need better control for generting {@link Listgroup} and{@link Listgroupfoot}, your renderer can also implement {@link ListgroupRendererExt}.
In addition, you could also implement {@link RendererCtrl}. For example, starts an transaction, and uses it to render all items for the same request. @author tomyeh @see ListModel @see Listbox @see ListitemRendererExt @see ListgroupRendererExt
