title: In XUL, how do I make my listbox fill the screen?
body: <p>I have the following xul file:</p>
  
  <pre><code>&lt;?xml version="1.0"?&gt;
  &lt;?xml-stylesheet href="chrome://global/skin/" type="text/css"?&gt;
  
  &lt;window id="main" title="MY TEST" width="640" height="480" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"&gt;
      &lt;listbox id="mainList"&gt;
        &lt;listitem label="Butter Pecan"/&gt;
        &lt;listitem label="Chocolate Chip"/&gt;
        &lt;listitem label="Raspberry Ripple"/&gt;
        &lt;listitem label="Squash Swirl"/&gt;
      &lt;/listbox&gt;
  &lt;/window&gt;
  </code></pre>
  
  <p>..and I would like this listbox to fill the screen (currently it is just on the top).</p>
  
  <p>Any idea?</p>
