Re: Correct way to sink events on UiBinder Element

Here's how I've done it for a click on a save button within a binder:  I don't have any call to sinkEvents - I think that's OK because the Widget class does that already (?)

    @UiField
    ButtonElement saveButton;

    // other UiFields

    public HandlerRegistration addSaveHandler(final ClickHandler handler) {
        return addDomHandler(new ClickHandler() {
            @Override
            public void onClick(ClickEvent event) {
                if (Element.as(event.getNativeEvent().getEventTarget()) == saveButton)
                    handler.onClick(event);
            }           
        }, ClickEvent.getType());
    }

I am defining several elements via UiBinder. My understanding is these are created as com.google.gwt.dom.client.Element during the createAndBind call.

I would like to add a click handler to one of these elements. Is there any way other than casting those to com.google.gwt.dom.client.Element like this?


@UiField 
Element clickable;

DOM.sinkEvents((com.google.gwt.user.client.Element) clickable, Event.ONCLICK);
DOM.setEventListener((com.google.gwt.user.client.Element) clickable, new EventListener() { 
public void onBrowserEvent(Event event) { 
//TODO: Some code

});
