JPanel Listener Problem

I have a JApplet that contains a JPanel. The JPanel contains
JComponents, each of which have a FocusListener. On FocusGained I do
something with the JComponent.

My problem is that I need the JApplet class to know each time the
FocusGained() method is invoked inside the JPanel and it needs to do
something based on the JComponent selected.

How do I implement a listener on the JPanel in the JApplet class that
will know when one of the components is clicked.

I tried adding a MouseListener, FocusListener, and a ContainerListener
to the JPanel and I've been unable to determine when a component was
clicked with each.

Any help would be great!

One way is to put a method in the applet that you can call from your
component focus listener.

Is that the only way? There's no listener that I can put on the JPanel
within the applet? It seems odd to have the JPanel send control back
to the Applet from the focus listener. What if the JPanel isn't
finished executing at the time that I need the Applet to execute
another process?

Creat a new class of listener that the Applet listens to and that the
JComponent fires.

You will have to write your own. Here is a really good article on how
to do that:

I think I would use the suggestion I gave you unless this is an exercise
in OO.
