Can't bind key abstract issue

Question

I developed everything in netbean, inside the jdesktop I want to allow user to close each jInternalFrame windows with shift+w.
    Action actionListener = new AbstractAction() {
      public void actionPerformed(ActionEvent actionEvent) {
          this.doDefaultCloseAction();
        String ACTION_KEY = "Do something";
        InputMap inputMap = this.getInputMap();
        ActionMap actionMap = this.getActionMap();
        this.setActionMap(actionMap);
        KeyStroke shiftF4 = KeyStroke.getKeyStroke(KeyEvent.VK_W,
            InputEvent.SHIFT_MASK);
        inputMap = this.getInputMap();
        inputMap.put(shiftF4, ACTION_KEY);
        this.setActionMap(actionMap);it keeps complaining
at this line:
Action actionListener = new AbstractAction() {
can not override abstract blah blah...how do I work around this?????

Answer 1

oh man, I ran into another issue. I have multiple actionlistener to gainFocus inside this jInternalFrame depending on the component user selected. So initially, I was able to sense for control + w keys for the main jInternalFrame. However, once the user clicked on one of child focus listener, such as a button, jTextField, etc... The actionListener for control + w is gone. How do I force the program to return back to jInternalFrame as the main focus owner once the child focus is lost?
