title: How to make JavaFX 2.0 ChoiceBox to select its first element
body: <p>When I create a JavaFX 2.0 ChoiceBox instance like this:</p>
  
  <pre><code>final ChoiceBox&lt;String&gt; fontChBox = 
    new ChoiceBox&lt;&gt;(FXCollections.observableArrayList("First", "Second", "Third"));
  </code></pre>
  
  <p>a choice box is displayed with no selection. I would like to select the first element by default. How to do it in JavaFX 2.0?</p>
