title: Changing DesktopIcon.width on nimbus
body: <p>I'm trying to change the <code>JInternalFrame</code> iconifying size, I've tried changing the L&amp;F defaults with 
  <code>javax.swing.UIManager.put("DesktopIcon.width", 300);</code> 
  but it doesn't work on Nimbus, I've also tried changing the <code>DesktopIconUI</code> with </p>
  
  <pre><code>javax.swing.UIManager.put("DesktopIconUI",  javax.swing.plaf.basic.BasicDesktopIconUI.class.getName());
  </code></pre>
