swing: appropriate Listener for JTextField change events

问题

Which type of Listener do I use for listening to changed text events in a JTextField? (I should know this or be able to tell from the Javadoc but I can't seem to figure it out.)

回答1:

Use the underlying document:

myTextField.getDocument().addDocumentListener();
