title: JList items with horizontal wrap not extending all the way through
body: <p>I have a Jlist like the one below. I am using the <code>JList.HorizontalWrap</code> to achieve this, but for some reason, after the 4th item in the list, it starts a new row.</p>
  
  <p>Here is the configurations I used to get the list looking this.</p>
  
  <pre><code>        sList.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION);
          sList.setVisibleRowCount(-1);
          sList.setLayoutOrientation(JList.HORIZONTAL_WRAP);
  </code></pre>
  
  <p>Is there any way I can set the List row count to be the width of the Jlist so that all items in the list will be set across before starting a new row?</p>
