        }
    };

    KeyStroke esc = KeyStroke.getKeyStroke(KeyEvent.VK_ESCAPE,0);
    getRootPane().getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put(esc, "closex");
    getRootPane().getActionMap().put("closex", closeAction);

    KeyStroke ctrlW = KeyStroke.getKeyStroke("control W");
    getRootPane().getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put(ctrlW, "close");
    getRootPane().getActionMap().put("close", closeAction);
