to the part of itself that produces an event when editing is complete, and 2) call
setProxy() with an EditorProxy through which the listener can retrieve a
new object value when editing is complete
- Returns:
- A UI component (eg JTextField) that allows the user to change the
object's value. If null, the calling property editor will attempt
to create a default editor, possibly using fromString(...).
