Is it possible to detect a date change on a JCalendar JDateChooser field?

I'd like to detect when the date is changed in a JDateChooser field so that I can update another field.

Is this possible? And if so where should I be starting? I've already looked at the documentation and unfortunately there are no methods for adding something like an ActionListener or StateChangeListener (my first thoughts).

com.toedter.calendar.JCalendar inherits a listenerList from JComponent and it implements java.beans.PropertyChangeListener. I'd add a listener and see what comes though.

Edit: I think you can use addPropertyChangeListener() the same way JCalendar does.

JDateChooser chooser = new JDateChooser();
chooser.getDateEditor().addPropertyChangeListener(
    new PropertyChangeListener() {
        @Override
        public void propertyChange(PropertyChangeEvent e) {
            if ("date".equals(e.getPropertyName())) {
                System.out.println(e.getPropertyName()
                    + ": " + (Date) e.getNewValue());
            }
        }
    });
this.add(chooser);

I've not tried it, but addDateListener(DateListener listener) looks appropriate.
