title: Sizing a HorizontalPanel cell
body: <p>Newbie Alert:</p>
  
  <p>I have been furiously looking for a way to size a particular cell of a HorizontalPanel. </p>
  
  <p>What I am trying to do is implement a 2-cell Horizontal Panel and set the left cell to say 200px. However, I am trying to make the right cell fill the rest of the window, not its cells contents.</p>
  
  <p>I cannot see the wood for the trees, please help...</p>
