How am I using KeyListener wrong in this code snippet?

Question

I'm trying to make pressing the enter key go to the next text field (TextField2), instead of (by default) it pressing the ok from JOptionPane's OK_CANCEL_OPTION.

   JTextField textField1 = new JTextField("");
   JTextField textField2 = new JTextField("");

   JPanel panel = new JPanel(new GridLayout(0,1));

   panel.add(new JLabel ("Check"));
   panel.add(textField1);
   panel.add(new JLabel ("Cash" ));
   panel.add(textField2);
   textField1.addAncestorListener(new SetFocus());
   textField1.addKeyListener(new KeyAdapter() {
    @Override
    public void keyPressed(KeyEvent e) {
        if(e.getKeyCode() == KeyEvent.VK_ENTER){
           textField2.addAncestorListener(new SetFocus());
        }
    }

});

   JOptionPane.showConfirmDialog(null, panel, "Deposit", JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE);

Use textfield2.requestFocus() instead of adding an ancestor listener.

That would not work. A component has to be visible before it can accept the focus. – Andrew Thompson Mar 16 '22 at 06:02
