neco jako:

JComponent component = getRootPane();
Action action = new AbstractAction() {
        @Override
        public void actionPerformed(ActionEvent e) {
            //akce pri uzavreni napr.:
            Dialog.this.setVisible(false);
        }
}

final KeyStroke keyStroke = KeyStroke.getKeyStroke(KeyEvent.VK_ESCAPE, 0);
Object key = "close action"; //nejaky nazev
component.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put(keyStroke, key);
component.getActionMap().put(key, action);
