Something for the wiki component reference?

Example for AjaxTabbedPanel:
1. create new Link with image - different for selected and different for
unselected tab
MyAjaxFallbackLink.java
------------------------------------------------
public class MyAjaxFallbackLink extends AjaxFallbackLink {
public MyAjaxFallbackLink(String id, boolean isSelectedTab) {
super(id);
Image image;
if (isSelectedTab){
image = new Image("image", new
ResourceReference(MyAjaxFallbackLink.class, "inner-image_selected.gif"));
}else{
image = new Image("image", new
ResourceReference(MyAjaxFallbackLink.class, "inner-image_unselected.gif"));
}
add(image);
}
public void onClick(AjaxRequestTarget target) {
//really nothing here -> to override
}
}
2. override newLink() in AjaxTabbedPanel to return your link
MyAjaxTabbedPanel.java
------------------------------------------------
public class MyAjaxTabbedPanel extends AjaxTabbedPanel {
public MyAjaxTabbedPanel(String id, List tabs) {
super(id, tabs);
setSelectedTab(0); //make sure, the first selected tab has
index=0.
Important for image in first selected tab!
}
protected WebMarkupContainer newLink(String linkId, final int index) {
int selectedTab = getSelectedTab();
boolean selected = (index == selectedTab);
return new MyAjaxFallbackLink(linkId, selected)
{
private static final long serialVersionUID = 1L;
public void onClick(AjaxRequestTarget target)
{
setSelectedTab(index);
if (target != null)
{
target.addComponent(MyAjaxTabbedPanel.this);
}
onAjaxUpdate(target);
}
};
}
}
3. copy html code from TabbedPanel.html and extend with image to pass
hierarchy
MyAjaxTabbedPanel.html
------------------------------------------------
<wicket:panel>
<div wicket:id="tabs-container" class="tab-row">
<ul>
<li wicket:id="tabs">
<a href="#" wicket:id="link"><img wicket:id="image"
class="left-image"/><span wicket:id="title">[[tab
title]]</span></a>
</li>
</ul>
</div>
<div wicket:id="panel" class="tab-panel">[panel]</div>
