Listening for mouse move from JFrame?

Question

Hi
I'm facing a problem when I wanted to use the JFrame's method: addMouseListener( ) to listening for the mouse whether it moves from a JFrame.
In my code the JFrame containts three components:
public class NFrame extends JFrame{
JPanel contentPane = (JPanel)super.getContentPane();
contentPane.setLayout(new BorderLayout());
JMenuBar jMenubar=new jMenuBar();
JTabbedPane jTabPane=new JTabbedPane(JTabbedPane.LEFT,JTabbedPane.WRAP_TAB_LAYOUT);
JPanel bottonPane=new JPanel();
contentPane.add(jMenuBar,BorderLayout.NORTH);
contentPane.add(jTabPane,BorderLayout.CENTER);
contentPane.add(bottomPane,BorderLayout.SOUTH);
addMouseListener(new MouseAdapter() {
public void mouseExited(MouseEvent e) {
System.out.println("Mouse remove from JFrame");
Because the JTabbedPane has a default mouse Listener, thus the mouse event is caught by jTabPane and the application does not print the above message when mouse moves from jTabPane.
Could anybody give me some hints?
Thanks!

In this case there should probably not be a sleep()
at all. You might want to do that sort of thing when
you have a new thread whose job is to have
non-GUI-related functionality (like a clock ticking,
or sprites moving in a game independently). For
standard GUI interaction, the GUI thread takes care
of things and you don't need to wait at all. You're
already waiting, basically.Oh, I see! The OP is doing quite useless things!
I didn't see such f**lish things in the past!
The OP should learn the basics for GUI and event mechanism.
