title: Documentation for @UiHandler
body: <p>I started to look into using GWT in combination with UiBuilder. I'm a bit puzzled about how you can use the <code>@UiHandler(..)</code> directive to make simple event handle code as written down in the <a href="http://code.google.com/webtoolkit/doc/latest/DevGuideUiBinder.html#Simple_binding" rel="noreferrer">GWT documentation</a>:</p>
  
  <pre><code>@UiHandler("button")
  void handleClick(ClickEvent e) {
    Window.alert("Hello, AJAX");
  }
  </code></pre>
  
  <p>In this case the method <code>handleClick</code> is used.
  How do you know for each GWT widget what methods can be created with <code>@UiHandler</code>? For some you can also create a <code>doClose()</code> method.</p>
  
  <p>But what can you use with, for instance, a <code>ListBox</code> to get an event an item is selected? Where in the documentation can I see this?</p>
