title: Is there a way to set underline to mnemonic character in native look and feel under Win 7?
body: <p>My code:  </p>
  
  <pre><code>fileMenu = new JMenu("File");
  fileMenu.setMnemonic(KeyEvent.VK_F);
  fileMenu.setDisplayedMnemonicIndex(0);
  </code></pre>
  
  <p><a href="http://docs.oracle.com/javase/6/docs/api/javax/swing/AbstractButton.html#setDisplayedMnemonicIndex%28int%29" rel="nofollow">Javadocs</a> for <code>AbstractButton.setDisplayedMnemonicIndex()</code> say that  </p>
  
  <blockquote>
    <p>Not all look and feels may support this.</p>
  </blockquote>
  
  <p>I set my look and feel to <code>UIManager.getSystemLookAndFeelClassName()</code></p>
  
  <p>And I don't see underline on mnemonic even when the index is explicitely  set by <code>setDisplayedMnemonicIndex()</code> - under Windows 7 (only when I press <code>ALT</code>).</p>
  
  <p>It works however if I do not set the look &amp; feel and leave just default java theme.</p>
  
  <p>Is there a way to achieve this? Is it caused by the settings of Windows ?</p>
