java - How to get a JTextField to respond to the enter key

Question

So I want to get a JTexField to put the text in it into a JTextArea when the enter key is pressed with the cursor in it. Can anyone help?

Answer 1

Forget about using KeyListener for Swing components.

This listener was designed for use with AWT components does not provide a reliable interaction mechanism for JTextComponents.

Use an ActionListener instead - on the vast majority of systems an ActionEvent is dispatched by the JTextField when enter is pressed.

myTextField.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent e) {
       myTextArea.append(myTextField.getText() + "
");
    }
});
