title: JScrollPane: fixed width, automatic height
body: <p>I'm using Swing for the first time and I've a problem with the JScrollPane...</p>
  
  <p>I've this structure</p>
  
  <blockquote>
    <p>JPanel west</p>
    
    <blockquote>
      <p>ScrollPane scrollPane</p>
      
      <blockquote>
        <p>JList list</p>
      </blockquote>
    </blockquote>
  </blockquote>
  
  <p>"west" contains "scrollPane".
  "scrollPane" contains "list"</p>
  
  <p>the "west" 's LayoutManager is a BorderLayout, now I want that the JScrollPane has a fixed width but the height adapts itself with the height of "west"...</p>
  
  <p>Is there a solution?</p>
