I am reading this page

http://jogamp.org/jogl/doc/NEWT-Overview.html

At the end it says: " The following example shows you how to use a fifo to pipe events from the EDT (listener) to the rendering loop. "

And in the TestParenting02NEWT.java, I see a while loop

 159         while (duration>0 && !shouldQuit) {
160             glWindow1.display();
161             glWindow2.display();
162             duration -= step;
163             x += 1;
164             y += 1;
165             // glWindow1.setPosition(x,y);
166             glWindow2.setPosition(glWindow1.getWidth()/2,glWindow1.getHeight()/2-y);
167             Thread.sleep(step);
168
169             while( null != ( event = eventFifo.get() ) ) {
170                 final Window source = (Window) event.getSource();
171                 if(WindowEvent.EVENT_WINDOW_DESTROY_NOTIFY == event.getEventType()) {
172                     shouldQuit = true;
173                 } else if(event instanceof KeyEvent) {
174                     final KeyEvent keyEvent = (KeyEvent) event;
175                     switch(keyEvent.getKeyChar()) {
176                         case 'q':
177                             shouldQuit = true;
178                             break;
179                         case 'f':
180                             source.setFullscreen(!source.isFullscreen());
181                             break;
182                     }
183                 }
184             }
185         }

Which is the difference between this and a keyListener?
