Description copied from class: BaseHandler

Returns a JTextField. An object is built from the text using fromString().

Specified by:

getEditor in interface ConfigurationHandler

Overrides:

getEditor in class BaseHandler

Parameters:

o - An object for which canHandle(o.getClass()) == true

listener - An ActionListener. The returned editor component must 1) add this listener 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

parent - Parent component

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(...).
