title: How to set font in NSTextView?
body: <p>As simple as it seems, I simply CANNOT find ANY way to do that (<code>setFont:</code> is not working) :</p>
  
  <ul>
  <li>Have a <code>NSTextView</code></li>
  <li>Set its font to some <code>NSFont</code>.</li>
  </ul>
  
  <hr>
  
  <p><strong>Hint :</strong> (Pretty obvious, but whatever... ) IF the user adds any text, the new text is supposed to 'inherit' the exact same style...</p>
