Why no Keyboard event?

Question

Hi,
Must be interpreting something wrong :-[.
public class LogInPanel extends JPanel
                        implements ActionListener,
                                   KeyListener,
                                   Observer {
     public LogInPanel (MyModel theModel){
          model = theModel;
          model.addObserver(this);
          // Create okButton and add it to the layout
          JComponent okButton = createButtonPanel();
          add(okButton);
          addKeyListener(this);
        // This method receives OK-button pressed events
     public void actionPerformed(ActionEvent event) {
          command = event.getActionCommand();
          if (OK.equals(command))
               checkFieldsAndLogIn();
     public void keyTyped(KeyEvent ke) {
          System.out.println ("LogInPanel.keyTyped, the " + ke.getKeyLocation() + " key was pressed");
          int keyCode = ke.getKeyCode();
          if ( keyCode == KeyEvent.VK_ENTER) {
               // Do something, like log in.
          // Make sure  the key isn't processed for anything else
          ke.consume();
     private JComponent createButtonPanel() {
          JPanel panel = new JPanel(new GridLayout(0,1));
          JButton okButton = new JButton("OK");
          okButton.setActionCommand(OK);
          okButton.addActionListener(this);
          panel.add(okButton);
          return panel;
     }Nothing is outputted to the console. What am I doing wrong?
TIA

Added example of ActionListener

Answer 1

That could possibly work. But, alas, no keyboard events happen in my code. I have println's in my code, and nothing is written to the console.
     public void keyTyped(KeyEvent ke) {
          System.out.println ("LogInPanel.keyTyped, the " + ke.getKeyLocation() + " key was pressed");
          if ( ke.getKeyChar() == KeyEvent.VK_ENTER) {
               System.out.println ("LogInPanel.keyTyped, the ENTER key was pressed");
     public void keyReleased(KeyEvent ke) {
          System.out.println ("LogInPanel.keyReleased, key " + ke.getKeyCode() + " was released");
      * User has pressed the Enter key, call <code>checkFieldsAndLogIn</code>
     public void keyPressed(KeyEvent ke) {
          System.out.println ("LogInPanel.keyPressed, key " + ke.getKeyCode() + " was pressed");
     }I think this is caused by my LogInPanel not having the focus. If you have a suggestion in that area, I would be obliged. But thanks for your help until now.
