JFileChooser Event

Looking to get the current file path so need to catch an event when there is a value change in the "Look In:" combobox in the JFileChooser below. I would like to fire the same event when the folder is selected from the list so I can keep updating the file path.

JFileChooser

I'm not looking for the event when the Open of Cancel buttons are pressed!

Any ideas?

When you change the folder in the "Look in:" combo box, only one PropertyChangeEvent is fired with the property name: JFileChooser.DIRECTORY_CHANGED_PROPERTY.

You can use this little code sample to test what property change events are fired in the background when you click around in the JFileChooser:

JFileChooser fc = new JFileChooser();
fc.addPropertyChangeListener(new PropertyChangeListener() {
    @Override
    public void propertyChange(PropertyChangeEvent evt) {
        System.out.println("Prop Change Event: " + evt.getPropertyName());
        if (JFileChooser.DIRECTORY_CHANGED_PROPERTY.equals(
                    evt.getPropertyName())) {
            // This is the event you're looking for
        }
    }
});

Note though that changing the current folder in the "Look in:" combo box is not the only event that generates a PropertyChangeEvent with property name DIRECTORY_CHANGED_PROPERTY, for example if you double click on a folder in the file list, that also generates this event (amongst other events like SELECTED_FILE_CHANGED_PROPERTY).
