title: How to use touch handlers? (does GWT support them?)
body: <p>I have a MouseDownHandler, MouseMoveHandler, and MouseUpHandler attached to a panel. I'd like to get the corresponding touch events to work the same way too. Is there any example of how this works with GWT? </p>
  
  <p>The events and handlers section in the docs are quite sparse:
  <a href="https://developers.google.com/web-toolkit/doc/latest/DevGuideUiHandlers" rel="nofollow">https://developers.google.com/web-toolkit/doc/latest/DevGuideUiHandlers</a></p>
  
  <p>so I must be missing it somewhere,</p>
  
  <p>Thanks</p>
  
  <p>----- Update ------------</p>
  
  <p>Ok so added this, but it doesn't fire:</p>
  
  <pre><code>// touchTest is just a div with width/height = 100%
  RootPanel rp = RootPanel.get("touchTest"); 
  rp.sinkEvents(Event.TOUCHEVENTS);
  rp.addHandler(new TouchStartHandler() {
      @Override
      public void onTouchStart(TouchStartEvent event) {
           // touch down!
      }
  }, TouchStartEvent.getType());
  </code></pre>
  
  <p>I have a mousedownhandler attached to the div like above, and it works fine when run in a desktop browser. Is there soething else we need to do?</p>
  
  <p>Thanks again</p>
