JavaFX如何将多个组件并排居中

import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {
        // 创建多个组件
        Button button1 = new Button("Button 1");
        Button button2 = new Button("Button 2");
        Button button3 = new Button("Button 3");

        // 创建HBox容器
        HBox hbox = new HBox();
        hbox.setAlignment(Pos.CENTER); // 设置水平居中对齐
        hbox.getChildren().addAll(button1, button2, button3); // 添加组件到容器

        // 创建场景并显示
        Scene scene = new Scene(hbox, 400, 200);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
