title: GWT 100% height panel with scroll
body: <p>Could anyone help me make normal layout in GWT.</p>
  
  <p>I need a main panel which:</p>
  
  <ol>
  <li><p>fills all the browser space (100% height);</p></li>
  <li><p>if being collapsed too much shows scroll bars (autoscroll).</p></li>
  </ol>
  
  <p>When I use old layout (RootPanel, VerticalPanel) I have scroll, but can't get 100% height.</p>
  
  <p>When I use new layout (RootLayoutPanel, DockLayoutPanel) I get 100% height, but I don't get any scroll. And also I have some troubles in IE.</p>
  
  <p>Is there any sample showing how to achieve both goals?</p>
  
  <p>Thanks in advance!</p>
