public class HorizontalPanelSoho extends HorizontalPanel implements

You just need to call addDomHandler in addClickHandler, and remove the
call from your constructor.

Re: How to add click handler to a panel?
If you are willing to wait till 2.1 or upgrade to the milestones
addHandler has been changed to public instead of protected.

How to add click handler to a panel?
Hi all, I want to listen to the click event for a panel, how can I catch this event? The Panel class doesn't have such methods like addClickHandler(). I don't want to use the sinkEvents() because in my case I just use this field panel as a button.

by implementing that class ClickHandler interface you can do it.
adding the following code to ur class
public HandlerRegistration addClickHandler(ClickHandler handler) {
return addDomHandler(handler, ClickEvent.getType());
}
u can implement like any handlers
