import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JPanel;
public class EscDialog extends JDialog implements KeyListener {
     static EscDialog ed = new EscDialog();
     public static void main(String[] args) {
          ed.setSize(200, 300);
          ed.addKeyListener(ed);
          JButton jb = new JButton("Test");
          JPanel jp = new JPanel();
          jp.add(jb);
          Container cp = ed.getContentPane();
          cp.add(jp);
          ed.show();
     public void keyPressed(KeyEvent anEvent) {
          if (anEvent.getKeyCode() == KeyEvent.VK_ESCAPE)
               System.exit(0);
     public void keyTyped(KeyEvent anEvent) {

An example:import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Test extends JDialog {
    public Test () {
        getContentPane ().setLayout (new FlowLayout ());
        getContentPane ().add (new JLabel ("Press escape to exit..."));
        getRootPane ().getInputMap ().put (KeyStroke.getKeyStroke (KeyEvent.VK_ESCAPE, 0), "dispose");
        getRootPane ().getActionMap ().put ("dispose", new AbstractAction () {
            public void actionPerformed (ActionEvent event) {
                dispose ();
        pack ();
        setDefaultCloseOperation (DO_NOTHING_ON_CLOSE);
        setLocationRelativeTo (null);
        setTitle ("Test");
        setVisible (true);
