title: GWT - event.getX() and event.getClientX()
body: <p>I added click handler to flowpanel as follows</p>
  
  <pre><code>this.addDomHandler(new ClickHandler(){
  
              @Override
              public void onClick(ClickEvent event) {
  
  
  
                  Window.alert("event.getX()="+event.getX()+" event.getY()="+event.getY());
                  Window.alert("event.getClientX()="+event.getClientX()+" event.getClientY()="+event.getClientY());
  
              }
  
              },ClickEvent.getType());
  </code></pre>
  
  <p>... as I could get it getX() returns mouse position within flowpanel but getClientX() returns another value and I couldn't get the value is coming from. So my question is what is the getClientXY() methods are used for?</p>
  
  <p>P.S
  GWT 2.2/2.3</p>
