        WindowUtils.setWindowAlpha(frame, value * 0.01f);

      }

    });

    container.add(slider, BorderLayout.SOUTH);

    RoundRectangle2D.Float mask = new RoundRectangle2D.Float(0, 0, frame.getWidth(), frame.getHeight(), 20, 20);

    WindowUtils.setWindowMask(frame, mask);

    centerWindow(frame);



  }



  public static void centerWindow(Container window) {

    Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();

    int x = (dim.width - w) / 2;

    int y = (dim.height - h) / 2;

    window.setLocation(x, y);

  }
