Question

如何使创建的VBox和Label对象出现在同一窗口中以及所需的位置？标签是标题。 VBox对象包含四个按钮。

我想使VBox Button对象出现在所创建窗口的标题下方。

使用此代码，仅显示标签对象“标题”。我还可以使VBox出现，但前提是它的列和行参数低于或等于Label对象的高度。

在我的MainClass类中调用该类以显示主菜单。

package application;

import javafx.application.Platform;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.geometry.Insets;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.VBox;
import javafx.scene.text.Font;
import javafx.stage.Stage;

public class MainMenu extends Stage{
   private Button[] buttArr = {new Button("New Game"),
         new Button("Save Game"),
         new Button("Load Game"),
         new Button("Exit Game")};

   private Label title = new Label("Bandit King");
   private GridPane grid = new GridPane();
   private VBox menuItems = new VBox();

   MainMenu() {
      grid.setHgap(10);
      grid.setVgap(10);
      grid.setPadding(new Insets(0, 10, 0, 10));

      menuItems.getChildren().addAll(buttArr);
      menuItems.setAlignment(Pos.CENTER_LEFT);
      menuItems.setSpacing(30);

      grid.add(title, 9, 7);
      grid.add(menuItems, 5, 25);


      this.setScene(new Scene(grid, 1600, 900));
      this.setTitle("Bandit King");
      this.show();

      // set title font
      Font.loadFont(getClass().getResourceAsStream("OLDSH.TFF"), 1);
      title.setFont(new Font("OldStyle 1 HPLHS", 100));
      title.getStyleClass().add("title");

      // set New Game Button action
      buttArr[0].setOnAction(new EventHandler<ActionEvent>() {
         @Override
         public void handle(ActionEvent t) {
            new Hideout();
         }
      });

      // set Save Game Button action
      buttArr[1].setOnAction(new EventHandler<ActionEvent>() {
         @Override
         public void handle(ActionEvent t) {
            System.out.println("WIP- save game");
         }
      });

      // set Load Game Button action
      buttArr[2].setOnAction(new EventHandler<ActionEvent>() {
         @Override
         public void handle(ActionEvent t) {
            System.out.println("WIP- load game");
         }
      });

      // set Exit Game Button action
      buttArr[3].setOnAction(new EventHandler<ActionEvent>() {
         @Override
         public void handle(ActionEvent t) {
            Platform.exit();
            System.exit(0);
         }
      });

   }
}

这是我的MainClass类：

package application;

import javafx.application.Application;
import javafx.stage.Stage;

public class MainClass extends Application {

   @Override
   public void start (Stage stage) {
      MainMenu mainMenu = new MainMenu();

      stage = mainMenu;

      stage.show();
   }



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

}

以下是此代码显示的内容：

import javafx.application.Application;
import javafx.stage.Stage;

/**

public class JavaFXApplication282 extends Application
{

    @Override
    public void start(Stage primaryStage)
    {
        MainMenu mainMenu = new MainMenu();

        primaryStage = mainMenu;

        primaryStage.show();
    }

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args)
    {
        launch(args);
    }

}

我注释了this.show();和new Hideout();，因为您没有发布Hideout类。

        menuItems.getChildren().addAll(buttArr);
        menuItems.setAlignment(Pos.CENTER_LEFT);
        menuItems.setSpacing(30);

        grid.add(title, 9, 7);
        grid.add(menuItems, 5, 25);

        this.setScene(new Scene(grid, 1600, 900));
        this.setTitle("Bandit King");
        // this.show();

        // set title font
        Font.loadFont(getClass().getResourceAsStream("OLDSH.TFF"), 1);
        title.setFont(new Font("OldStyle 1 HPLHS", 100));
        title.getStyleClass().add("title");

        // set New Game Button action
        buttArr[0].setOnAction(new EventHandler<ActionEvent>()
        {
            @Override
            public void handle(ActionEvent t)
            {
                // new Hideout();
            }
        });

        // set Save Game Button action
        buttArr[1].setOnAction(new EventHandler<ActionEvent>()
        {
            @Override
            public void handle(ActionEvent t)
            {
                System.out.println("WIP- save game");
            }
        });

        // set Load Game Button action
        buttArr[2].setOnAction(new EventHandler<ActionEvent>()
        {
            @Override
            public void handle(ActionEvent t)
            {
                System.out.println("WIP- load game");
            }
        });

        // set Exit Game Button action
        buttArr[3].setOnAction(new EventHandler<ActionEvent>()
        {
            @Override
            public void handle(ActionEvent t)
            {
                Platform.exit();
                System.exit(0);
            }
        });

    }
}

我运行您的代码的输出。
