Re: How to remove EventListener

Surprised at your reaction to this.  I find myself doing the same more and more as I'm using less and less widgets.  Is there a better way when dealing with non-widget elements?

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);
