更改场景时如何保持全屏javafx

我看到一个类似的问题被问到,但我的问题是我希望舞台在整个场景变化期间保持全屏模式,即不要简单地在其末尾添加stage.setFullScreen(true),这会导致一个瞬间但非常明显的退出全屏幕。在改变场景之前隐藏舞台并不是真的有帮助,因为有明显的消失。这是我的代码:

主:

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);
    }
}

控制器:

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();
    }

}

样品:

<?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>

<?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="-

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>

正如您所看到的,如果您运行代码并按下按钮,则会全屏退出。有没有办法解决这个问题,除了使用相同的fxml文件?

非常感谢。

我不清楚你在说什么。我认为你需要一个大小等于计算机屏幕分辨率的阶段,并在两个屏幕之间切换。如果是,那么以下文件将帮助您这样做。如果你想从第二个场景回到第一个场景,那么保持另一个按钮来加载第一个场景或者保持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。喜欢变量显示第一个场景的奇数值和偶数值显示第二个场景。

其他过程正在让孩子们登台。这给你一个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。

        primaryStage.setWidth(primaryScreenBounds.getWidth());
        primaryStage.setHeight(primaryScreenBounds.getHeight());
        primaryStage.show();

    }

    public static void main(String[] args) {

        stage.setWidth(primaryScreenBounds.getWidth());
        stage.setHeight(primaryScreenBounds.getHeight());
        stage.show();

    }
