private static void initAndShowGUI() throws Exception
   {
      JFrame frame = new JFrame("Swing and JavaFX");
      final JFXPanel fxPanel = new JFXPanel();
      frame.add(fxPanel);
      frame.setSize(300, 200);
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

      if (!SET_FRAME_VISIBLE_LATE)
      {
         setFrameVisible(frame);
      }

      Platform.runLater(() -> {
                      try {
                      initFX(fxPanel, frame);
                      } catch (Exception e) {}
      });
      if (SET_FRAME_VISIBLE_LATE)
      {

      }
   }

   private static void initFX(JFXPanel fxPanel, JFrame frame) throws Exception

      Scene scene = createScene();
      fxPanel.setScene(scene);
