KeyAdapters and Focus

Question

I have a KeyAdapter that I'd like to have catch all keystrokes made while the application is open. However, keyAdapters only will listen to the component that they are registered to. When a user clicks a JButton, the further keystrokes are not heard...
I can set the initial focus...
        window.addKeyListener(PrimaryWindow.keyadapter);
        window.setFocusTraversalKeysEnabled(false);
        window.setFocusable(true);
        window.requestFocus();But what should I do when the user starts doing things?
Should I add the listener to everything? Should I make my other components always refocus on the window?
Thanks in advance,
Andy

Answer 1

this class should catch all key events and can manage them on its own (i've not tested it- it's a shorter version of a complex class i use in my games)
class MyKeyboard implements KeyEventDispatcher {
  public MyKeyboard{
    KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(this);
public boolean dispatchKeyEvent(KeyEvent ke) {
    switch( ke.getID() ) {
// ************************************ KEY PRESSED ***********************************************
   case KeyEvent.KEY_PRESSED:
    int key_press=ke.getKeyCode();
    break;
// ************************************ KEY RELEASED **********************************************
    case KeyEvent.KEY_RELEASED:
      int key_release=ke.getKeyCode();
      break;
    }//end switch
return true;
}// end void dispatchKeyEvent
}
