public void start(Stage stage) throws Exception {
        longStart();
        Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));
         
        Scene scene = new Scene(root);
         
        stage.setScene(scene);
        stage.initStyle(StageStyle.UNDECORATED);//設定窗口無邊框
        stage.show();
    }
