You could add an KeyListener to the Dialog and listen for the "esc" key.

You need something like:

            dialog = new JDialog(this);
            dialog.addKeyListener(new CloseAction());
......
 
    private class CloseAction extends KeyAdapter {
        public void keyPressed(KeyEvent e) {
            if (e.getKeyChar() == KeyEvent.VK_ESCAPE) {
                dialog.dispose();
            }
        }
    }   

Open in new window
