JavaFX 修复窗格的布局

[英]JavaFX Fix Layout of Pane

 原文  2017-11-15 17:14:28  8   1    java/ javafx

问题描述

我希望通过将 gridPanes 添加到 Pane 来使用 JavaFX 对简单的微波炉进行建模。 微波炉

以上是结果应该是什么样子，但我无法正确布置 gridPanes。

任何有关我如何改进这一点的帮助将不胜感激。 这是我的结果的样子和我的代码。

我的输出

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
import javafx.geometry.Insets;
import javafx.scene.control.TextField;
import javafx.scene.layout.ColumnConstraints;
import javafx.scene.layout.Priority;
import javafx.scene.layout.Pane;
import javafx.scene.control.Label;

public class Microwave extends Application
{
    @Override
    public void start(Stage primaryStage)
    {
        Pane root = new Pane();
        GridPane gPane1 = new GridPane();
        GridPane gPane2 = new GridPane();
        TextField time = new TextField("Time to be displayed here");
        Label food = new Label("Place food here");

        Button start_button = new Button("Start");
        Button stop_button = new Button("Stop");
        Button button_0 = new Button("0");
        Button button_1 = new Button("1");
        Button button_2 = new Button("2");
        Button button_3 = new Button("3");
        Button button_4 = new Button("4");
        Button button_5 = new Button("5");
        Button button_6 = new Button("6");
        Button button_7 = new Button("7");
        Button button_8 = new Button("8");
        Button button_9 = new Button("9");

        gPane1.add(start_button, 1, 3);
        gPane1.add(stop_button, 2, 3);
        gPane1.add(button_0, 0, 3);
        gPane1.add(button_1, 0, 0);
        gPane1.add(button_2, 1, 0);
        gPane1.add(button_3, 2, 0);
        gPane1.add(button_4, 0, 1);
        gPane1.add(button_5, 1, 1);
        gPane1.add(button_6, 2, 1);
        gPane1.add(button_7, 0, 2);
        gPane1.add(button_8, 1, 2);
        gPane1.add(button_9, 2, 2);

        gPane2.add(time,0,0);

        root.getChildren().addAll(gPane1,gPane2,food);      

        Scene scene = new Scene(root,200,50);
        primaryStage.setTitle("Microwave Oven");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

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

}

这是在SceneBuilder 中创建的示例。 您可以使用FXML找出如何在代码中执行此操作。
