A default value for this is determined by the messageType parameter.

When the selection is changed, setValue is invoked, which generates a PropertyChangeEvent. For more information see Swing's Threading Policy.

The user will able to choose from selectionValues , where null implies the user can input whatever they wish, usually by means of a JTextField.
