swing JFrame listener questions

Hi,
I have a "class A extends JFrame". On this class i have (created and)added class C and D objects - "class C extends JPanel" and "class D extends JPanel".
Which listener do i have to use in order to know if ANYTHING has changed either in objects A OR C and D?
Thanks

the action listener attach to the object in focus for instance
in your jframe you make a jpanel

Code:

JPanel B = new JPanel();

you put it in your jframe
then give it a listener like

Code:

B.addActionListener(new java.awt.event.ActionListener() {
