title: Filter button properties set for right click
body: <p>I want to give the filter button a right click function that when I right click it, it will clear all the grid criteria.</p>
  
  <pre><code>        setFilterOnKeypress(false);
          setFilterByCell(true);
          setFilterButtonPrompt("Left click to filter, right click to clear all texts.");
          Button button = new Button();
          button.addClickHandler(new ClickHandler()
          {
  
              @Override
              public void onClick(ClickEvent event)
              {
                  if (event.isRightButtonDown())
                  {
                      SC.warn("right clicked");
                      clearCriteria();
                  }
              }
          });
          setFilterButtonProperties(button);
  </code></pre>
  
  <p>This is not working, any ideas on why it isnt working?</p>
