JButton keeps JFrame from succesfully implementing KeyListener?!

Question

Look at this code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Test extends JFrame implements KeyListener
     private JButton myButton;
     public Test()
          Container c = getContentPane();
          c.setLayout( new FlowLayout() );
          myButton = new JButton();
          myButton.setEnabled( true );
          c.add( myButton );
          addKeyListener( this );
          setSize( 100, 100 );
          show();
     public void keyPressed( KeyEvent e )
            System.out.println( "keyPressed" );
     public void keyReleased( KeyEvent e )
          System.out.println( "keyReleased" );
     public void keyTyped( KeyEvent e )
          System.out.println( "keyTyped" );
     public static void main( String args[] )
          Test window = new Test();
}When you execute this program, the JFrame does not resolve keystrokes. It should though, because it implements KeyListener and overrides all required methods. But here is the strange thing: Try changing
myButton.setEnabled( true );to
myButton.setEnabled( false );Now the JFrame is able to respond to keystrokes by executing the proper methods! But what use is a button if it is not enabled. I need my buttons in the JFrame, but I also need the JFrame to respond to the keystrokes.
Anyone know about this problem and how to solve it??
Thank you!

Answer 1

?? Say you want to make a small game. A square is drawn onto the frame. The user presses the up button on the keybord and the square 'moves' up (it is repainted at a different coordinate). But the user also needs to be able to (re)start the game and exit through the use of JButtons. That is the purpose and the problem is stated in my first post...
Anyone else has an idea?
thx
