Re: Correct way to sink events on UiBinder Element

It sounds like you're using an HTML-based binder, not a Widget binder, so your createAndBindUi would produce an Element that your class can set as its DOM representation (I usually make my class extend Element - for some reason the Eclipse wizard wants to make it a UiObject).  And, then, as another poster mentioned, you can have SpanElement, DivElement, etc., in the Java class to match what's in the xml. So, you shouldn't have to cast to element, the pieces should already be some sort of Element.

I'm pretty sure @UiHandler won't work for an HTML-based binder, since the Java fields aren't widgets.

I haven't tried your approach for hooking up handlers, but have used a delegating approach - the Java class, as a Widget, can have a regular click handler, which can then look at the target of the event and decide what to do accordingly (like fire off a custom event that represents whatever clicking the element meant).

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

} 
});
