How to propogate Swing events from a inner component to a container?

You can use javax.swing.event. EventListenerList in the JPanel containing the JTextField, and create a addKeyListener public method.

Try adding an ActionListener to the JPanel. The actionPerformed() method in the ActionListener will get called when the user presses key in the JTextfield. You can call getSource() on the event object to determine if the event was fired due to action in JTextField and act accordingly.
