Re: addKeyListener is NOT working

When I press a key the keyPressed() procedure is NOT called. Why ?
In contrast the button events working successfully.

Possible the key-Event is not forwarded to the "outer" level.
How do I forward these events otherwise?

public class xxx extends JFrame implements ActionListener, KeyListener {
     boolean inAnApplet = true;

     public xxx() {

        ...
        mybutton.addActionListener(this);
        ...
        addKeyListener(this);
        ...
        ...
        addWindowListener(new WindowAdapter() {
              public void windowClosing(WindowEvent e) {
                  if (inAnApplet) {
                      dispose();
                  } else {
                      System.exit(0);
                  }
              }
          });
         }

     public void keyPressed(KeyEvent e) {
      System.out.println("In KeyPressed"); // never reached !!
      ... }

   public void actionPerformed(ActionEvent e){
      System.out.println("In ActPerf"); //reached !!
      ... }
     }

  public static void main(String args[]) {
     ...
     xxx window = new xxx();
     }
