Using the keyboard to activate a button

Question

Say I have a JTextfield and a JButton. I want the Enter key to do the same thing as clicking on the JButton. I thought there might be a way to do it by having the JTextfield watch for "/n", but I couldn't figure it out. I searched ActionEvent in the documentation, and I didn't find much help there either.

Answer 1

Hmm... JTextField supports ActionListeners, the same as a JButton, so if you register an ActionListener with the field, hitting enter is supposed to fire an ActionEvent.
ActionListener al = new ActionListener() {
public void actionPerformed(ActionEvent ae) {
System.out.println(ae.getSource());
JTextField tf = new JTextField();
tf.addActionListener(al);
JButton bt = new JButton("enter");
bt.addActionListener(al);
