title: Populating Swing JComboBox from Enum
body: <p>I would like to populate a <code>java.swing JComboBox</code> with values from an <code>Enum</code>.</p>
  
  <p>e.g. </p>
  
  <pre><code>public enum Mood { HAPPY, SAD, AWESOME; }
  </code></pre>
  
  <p>and have these three values populate a readonly <code>JComboBox</code>.</p>
  
  <p>Thanks!</p>
