public class TabbedPanel<T extends ITab> extends Panel
TabbedPanel component represents a panel with tabs that are used to switch between different content panels inside the TabbedPanel panel.

Note: When the currently selected tab is replaced by changing the underlying list of tabs, the change is not picked up unless a call is made to setSelectedTab(int).

Example: 

 List tabs=new ArrayList();
 tabs.add(new AbstractTab(new Model<String>("first tab")) {
   public Panel getPanel(String panelId)
   {
     return new TabPanel1(panelId);
   }
 });
 
 tabs.add(new AbstractTab(new Model<String>("second tab")) {
   public Panel getPanel(String panelId)
   {
     return new TabPanel2(panelId);
   }
 });
 
 add(new TabbedPanel("tabs", tabs));
 
 <span wicket:id="tabs" class="tabpanel">[tabbed panel will be here]</span>

    • onBeforeRender

      protected void onBeforeRender()
      Description copied from class: Component
      Called on all visible components before any component is rendered.

      NOTE: If you override this, you *must* call super.onBeforeRender() within your implementation. Because this method is responsible for cascading Component.onBeforeRender() call to its children it is strongly recommended that super call is made at the end of the override.

      Changes to the component tree can be made only before calling super.onBeforeRender().
      Overrides:
      onBeforeRender in class Component
