java - javafx切换场景时如何保持全屏

Question

我看到有人问过类似的问题，但我的问题是我希望舞台在整个场景更改期间保持全屏模式，即不简单地在末尾添加 stage.setFullScreen(true) ，这会导致短暂但非常明显的退出全屏。在改变场景之前隐藏舞台也没有什么帮助，因为有明显的消失。这是我的代码:

主要:

package sample;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setTitle("Hello World");
        primaryStage.setScene(new Scene(root));
        primaryStage.setFullScreen(true);
        primaryStage.show();
    }


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

Controller :

package sample;

import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.stage.Stage;


public class Controller {

    @FXML
    private AnchorPane pane;

    @FXML
    void doSomething(ActionEvent event) throws Exception {
        Stage stage = (Stage) pane.getScene().getWindow();
        Parent parent = FXMLLoader.load(getClass().getResource("sample2.fxml"));
        Scene scene = new Scene(parent);
        stage.setScene(scene);
        stage.setFullScreen(true);
        stage.show();
    }

}

示例:

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.AnchorPane?>


<AnchorPane fx:id="pane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-
Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" 
xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1" 
fx:controller="sample.Controller">
    <children>
      <Button layoutX="180.0" layoutY="188.0" mnemonicParsing="false" 
onAction="#doSomething" prefHeight="25.0" prefWidth="241.0" text="Do Something" 
/>
   </children>
</AnchorPane>

示例2

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.AnchorPane?>


<AnchorPane fx:id="pane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-
Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0"  style="-fx-background-color: blue;" 
xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1" 
fx:controller="sample.Controller">
    <children>
      <Button layoutX="180.0" layoutY="188.0" mnemonicParsing="false" 
onAction="#doSomething" prefHeight="25.0" prefWidth="241.0" text="Do Something" 
/>
   </children>
</AnchorPane>

如您所见，如果运行代码并按下按钮，则会暂时退出全屏。除了使用相同的 fxml 文件之外，还有其他方法可以解决此问题吗？

非常感谢。

我没太明白你在说什么。我认为你需要一个大小等于计算机屏幕分辨率的舞台并在两个屏幕之间切换。如果是，那么以下文件将帮助您做到这一点。如果您想从第二个场景返回到第一个场景，请保留另一个按钮来加载第一个场景或保留静态变量并通过递增变量在场景之间切换并根据奇数或偶数显示场景。就像变量的奇数值显示第一个场景，偶数值显示第二个场景一样。

其他过程是获取舞台的子级。这会给你一个 ObservableList。现在清除列表，然后将相应的场景添加到列表中并显示舞台。

主类:

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.geometry.Rectangle2D;
import javafx.scene.Group;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Screen;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setTitle("Hello World");
        Scene scene = new Scene(root, 500, 200);
        primaryStage.setScene(scene);
        Rectangle2D primaryScreenBounds = Screen.getPrimary().getVisualBounds();
        //set Stage boundaries to visible bounds of the main screen
        primaryStage.setX(primaryScreenBounds.getMinX());
        primaryStage.setY(primaryScreenBounds.getMinY());
        primaryStage.setWidth(primaryScreenBounds.getWidth());
        primaryStage.setHeight(primaryScreenBounds.getHeight());
        primaryStage.show();

    }

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

Controller 类:

import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.geometry.Rectangle2D;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.stage.Screen;
import javafx.stage.Stage;

public class Controller {

    @FXML
    private AnchorPane pane;

    @FXML
    void doSomething(ActionEvent event) throws Exception {
        Stage stage = (Stage) pane.getScene().getWindow();
        Parent parent = FXMLLoader.load(getClass().getResource("sample2.fxml"));
        Scene scene = new Scene(parent, 500, 200);
        stage.setScene(scene);
        Rectangle2D primaryScreenBounds = Screen.getPrimary().getVisualBounds();
        //set Stage boundaries to visible bounds of the main screen
        stage.setX(primaryScreenBounds.getMinX());
        stage.setY(primaryScreenBounds.getMinY());
        stage.setWidth(primaryScreenBounds.getWidth());
        stage.setHeight(primaryScreenBounds.getHeight());
        stage.show();

    }
}
