Examples of org.w3c.dom.events.EventListener

org.w3c.dom.events.EventListener
The EventListener interface is the primary method for handling events. Users implement the EventListener interface and register their listener on an EventTarget using the AddEventListener method. The users should also remove their EventListener from its EventTarget after they have completed using the listener. @since DOM Level 2

        // remove all listeners added by Bridges
            Iterator iter = eventListenerSet.iterator();
        while (iter.hasNext()) {
            EventListenerMememto m = (EventListenerMememto)iter.next();
            EventTarget   et = m.getTarget();
            EventListener el = m.getListener();
            boolean       uc = m.getUseCapture();
            String        t  = m.getEventType();
            if ((et == null) || (el == null) || (t == null))
                continue;
            et.removeEventListener(t, el, uc);
