title: Java: Editable JCombobox in JOptionPane inputDialog?
body: <p>Following the example here <a href="http://www.java2s.com/Code/JavaAPI/javax.swing/JOptionPaneshowInputDialogComponentpObjectmStringtintmIconiObjectoObjecti.htm" rel="noreferrer">http://www.java2s.com/Code/JavaAPI/javax.swing/JOptionPaneshowInputDialogComponentpObjectmStringtintmIconiObjectoObjecti.htm</a></p>
  
  <p>is it possible to somehow make the default jcombobox editable? There doesn't seem to be any instantiation of JCombobox in the JOptionPane, is it possible to extend and override the default JCombobox used by JOptionPane?</p>
