   I want to add a key listener to a JInternalFrame.
  I try this:

       JInternalFrame frame =3D new JInternalFrame(.....);
      ....
       frame.addKeyListener(new KeyAdapter() {
           public void keyPressed(KeyEvent e) { =20
                ...
           }
      }
=20
  but doesn't work.

  Thanks.
