在游戏菜单中配对<string，runnable =“”>

Question

我正在尝试使用javafx创建游戏菜单。我现在有可以使用的首页。我有几个项目应该引导我进入下一个场景。

我使用：

 private List<Pair<String, Runnable>> menuData = Arrays.asList(
        new Pair<String, Runnable>("Un Joueur", OptionMenu::),
        new Pair<String, Runnable>("Multijoueuer", () -> {}),
        new Pair<String, Runnable>("Options du jeu", () -> {}),
        new Pair<String, Runnable>("Quitter",Platform::exit)
);

创建我的商品，然后Platform ::退出所有内容。

问题是：我如何创建像OptionMenu :: something 这样的Runnable，使我进入扩展应用程序的下一页。我希望它与之接近：

public abstract static class OptionMenu extends Application implements Runnable{

///////// définition de la taille du menu ///////////
private static final int WIDTH = 1324;
private static final int HEIGHT = 604;

/////////////////////////////////////////////////////

//////// création des differents clicables //////////
private List<Pair<String, Runnable>> menuData = Arrays.asList(
        new Pair<String, Runnable>("Un Joueur", () -> {}),
        new Pair<String, Runnable>("Multijoueuer", () -> {}),
        new Pair<String, Runnable>("Options du jeu", () -> {}),
        new Pair<String, Runnable>("Quitter",Platform::exit)
);

//////////////////////////////////////////////////////

private Pane root = new Pane();
private VBox menuBox = new VBox(-5);


private void addBackground(){
    ImageView imageView = new ImageView(new Image(getClass().getResource("MenuImages/bkground.jpg").toExternalForm()));
    imageView.setFitWidth(WIDTH);
    imageView.setFitHeight(HEIGHT);

    root.getChildren().add(imageView);
}

private void addTitle() {
    BomberBallTitle title = new BomberBallTitle("Options du jeu");
    title.setTranslateX(WIDTH / 2 - title.getTitleWidth() / 2);
    title.setTranslateY(HEIGHT / 3);

    root.getChildren().add(title);
}


private void addMenu(double x, double y) {
    menuBox.setTranslateX(x);
    menuBox.setTranslateY(y);
    menuData.forEach(data -> {

        BomberBallMenuItem item = new BomberBallMenuItem(data.getKey());
        item.setOnAction(data.getValue());
        item.setTranslateX(-300);

        Rectangle clip = new Rectangle(300, 30);
        clip.translateXProperty().bind(item.translateXProperty().negate());

        item.setClip(clip);

        menuBox.getChildren().addAll(item);
    });

    root.getChildren().add(menuBox);
}

private Parent createContent() {
    addBackground();
    addTitle();
    double lineX = WIDTH / 2 - 100;
    double lineY = HEIGHT / 3 + 50;

    addMenu(lineX + 5, lineY + 5);

    return root;
}

public void run() {
    launch();
}



@Override
public void start(Stage primaryStage) throws Exception{
    Scene scene = new Scene(createContent());
    primaryStage.setTitle("BomberBall Menu");
    primaryStage.setScene(scene);
    primaryStage.show();
}
