Re: How to remove EventListener

I use the following code to create an EventListener:

                     final EventListener listener = new EventListener() {...};
                     Event.setEventListener(divElement, listener);

Please tell me this is legacy code from GWT 1.x times…
(why not use a widget? or event delegation?)
 
How do I remove EventListener late if I don't want to delete the created divElement?

If you want to stop listening to all events (and easily reattach the listener later on, triggered on the same events):
Event.setEventListener(divElement, null);
to stop listening to click events:
Event.sinkEvents(divElement, 0); // unsinks all events, but you only had ONCLICK
or
Event.sinkEvents(divElement, Event.getEventsSunk() & ~Event.ONCLICK);
