在全屏JavaFX中更改场景

问题描述

我是JavaFX的新手。我有我的主要和次要场景;当我从第一个场景改为第二个场景时，窗口的栏变得可见。我该如何解决？

I'm new to JavaFX. I have my main and secondary scenes; when I change from the first scene to the second one, the window's bar becomes visible. How can I fix that?

这是我的代码

public class ProyectoTeoriaBD1 extends Application {

Stage primaryStage;

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

@Override
public void start(final Stage primaryStage) {

    this.primaryStage = primaryStage;
    GridPane gp = new GridPane();
    gp.setHgap(10);
    gp.setVgap(10);
    gp.setPadding(new Insets(25,25,25,25));

    Scene firstScene = new Scene(gp);
    Button b = new Button("Change Scene");
    gp.add(b,1,1);
    primaryStage.setScene(firstScene);
     primaryStage.setFullScreen(true);
    primaryStage.show();



   b.setOnAction(new EventHandler<ActionEvent>() {

        @Override
        public void handle(ActionEvent event) {
           GridPane gp = new GridPane();
           Scene secondScene = new Scene(gp);
           Text txtSecond = new Text("Second Scene");
           gp.add(txtSecond, 1, 1);
           primaryStage.setScene(secondScene);
           primaryStage.setFullScreen(false);
           primaryStage.setFullScreen(true);

        }
    });


}

}

推荐答案

完整的可运行的可测试代码可能会有所帮助。还提供您的系统环境详细信息。我已经测试了下面的代码（尝试自己），它适用于我的Windows 7 64位JavaFX版本2.2.0。

（我会更新我的答案，因为你提供了更多细节，最后欢迎来到stackoverflow！）

A full runnable testable code could be helpful. Also provide your system environment details. I have tested your code below (try yourself) which works on my windows 7 64 bit with JavaFX version 2.2.0.
(I will update my answer as you provide more details and lastly welcome to stackoverflow!)

更新：好我猜我的初级阶段最初处于全屏模式。在这种情况下，您需要切换全屏模式。见下文。

Update: Ok I guess your primary stage was in full screen mode initially. In that case you need to toggle full screen mode. See below.

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBoxBuilder;
import javafx.scene.text.Text;
import javafx.stage.Stage;

public class Test extends Application {
    private Stage primaryStage;

    @Override
    public void start(Stage primaryStage) {
        this.primaryStage = primaryStage;
        this.primaryStage.setFullScreen(true);
        Button btn = new Button("Login");
        btn.setOnAction(loginClienteHandler());

        StackPane root = new StackPane();
        root.getChildren().add(btn);

        Scene scene = new Scene(root, 300, 250);

        primaryStage.setTitle("JavaFX version: " + com.sun.javafx.runtime.VersionInfo.getRuntimeVersion());
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public EventHandler loginClienteHandler() {
        EventHandler evh = new EventHandler<ActionEvent>() {
            @Override
            public void handle(ActionEvent event) {
                primaryStage.setScene(new Scene(VBoxBuilder.create().children(new Text("text")).build()));
                primaryStage.sizeToScene();
                primaryStage.setFullScreen(false);
                primaryStage.setFullScreen(true);
            }
        };
        return evh;
    }

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