title: JavaFX Get ComboBox from ChoiceDialog
body: <p>I have a <code>javafx.scene.control.ChoiceDialog</code> object in my JavaFX project.  When the dialog opens, I want to set the focus to the underlying <code>ComboBox</code>.  However, I can't figure out how to get the underlying <code>ComboBox</code> control.  With a <code>TextInputDialog</code>, there is a method called <code>getEditor()</code>.  Is there any way (other than reflectively accessing the private <code>comboBox</code> member) to get the underlying <code>ComboBox</code>?</p>
