how to add Header click event Listener

[mamatachaudhari]

Hi,
my code is



contentPanel.getHeader().addListener(Events.OnClick, new Listener<ComponentEvent>(){
public void handleEvent(ComponentEvent be)
{

HorizontalPanel contentPanel = (HorizontalPanel )be.getSource().getParent();
System.out.println("In listener ===="+contentPanel);



　
}
});



But after clicking on header nothing is happening....
Could any one please tell me where is exact problem.
I tried Events.HeaderClick also but no luck.
Give me any solution

Use BaseEvent instead of ComponentEvent:


ContentPanel cp = new ContentPanel();
cp.getHeader().addListener(Events.OnClick, new Listener<BaseEvent>() {

@Override
public void handleEvent(BaseEvent be) {
Info.display("Test Title", "Test Content");
}
});

RootPanel.get().add(cp);

contentPanel.getHeader().sinkEvents(Event.ONCLICK);
contentPanel.getHeader().addListener(Events......

Since GXT 2.2 the browser event gets automatically sunk.
