Cell Browser External Listener

Dear GWT Users,

Thanks in advance for any help.

I have working CellBrowser that I want to add an external listener to (so that I can display data clicked on... but outside and in another panel).  I see CellBrowser implements HasClickHandlers (and addClickHandler).

http://www.gwtproject.org/javadoc/latest/com/google/gwt/user/cellview/client/CellBrowser.html

I can successfully handle an event internally in my Cell i.e.

public void onBrowserEvent(Context context, Element parent, Track value, NativeEvent event, ValueUpdater<Track> valueUpdater) {
   
    super.onBrowserEvent(context, parent, value, event, valueUpdater);
    
    if ("click".equals(event.getType())) {
     
        EventTarget eventTarget = event.getEventTarget();
        GWT.log("You selected " + value.getName() + " by " + value.getArtist());
    }
}

I thought (given the interfaces it implements) I could do something like

CellBrowser cellBrowser = cbb.build();

cellBrowser.addHandler(new ClickHandler() {
    @Override
    public void onClick(ClickEvent clickEvent) {
        
    }
});


But it appears not.  What and how is the best way to externally listen to CellBrowser and Cell events, so that I can display the event info "outside" in another e.g. Panel?

Regards, Sam
