Is there an analogue to TextListener/TextEvent (of AWT's TextField) for JTextField?

But of course...

Swing uses a Model-View-Controller paradigm. Rather than watching the "component" for changes, you need to watch its model

For example:

JTextField f = new JTextField();

Document doc = f.getDocument();

doc.addDocumentListener(
  new DocumentListener() {
    public void changedUpdate(DocumentEvent e) {
      // when text/attributes change...
    }
    public void insertUpdate(DocumentEvent e) {
      // when text inserted...
    }
    public void removeUpdate(DocumentEvent e) {
      // when text removed...
    }
  });
