title: Eclipse autocompletion for GWT UiBinder (+ UiBinder documentation)
body: <p>I am using UiBinder xml files in a GWT project. The problem is that Eclipse doesn't give me any info about what attribute I can use with the widgets</p>
  
  <p>For example I know I can set width or style this way :</p>
  
  <pre><code>&lt;g:HorizontalPanel width="100%" addStyleNames="{style.mainPanel}"&gt;
  </code></pre>
  
  <p>But they are not mentioned in the list that appears after clicking ctrl + space. So I don't know what other options I have. How can I get them ?</p>
  
  <p>More generally I find it hard to find complete documentation on what we can do in the UiBinder. Which leads to spending a lot of time to find how to deal with <a href="https://stackoverflow.com/questions/3038540/listbox-gwt-using-uibinder/">simple features like this one</a> Has anybody got any good links.</p>
