javafx setFullScreen (), сцена не покрывает весь экран

/ 04 января 2019

Ohey! Я создаю медиаплеер с javafx, и у меня возникла досадная проблема с методом setFullScreen: когда я делаю двойной щелчок, чтобы сделать это, видео не покрывает весь мой монитор, но в нижней части экрана появляется видимый часть макета моей сцены строителей посмотрите на нижнюю часть, там есть часть макета!

так вот мой код:

MAIN 

package sample;

import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.input.MouseEvent;
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"));
        Scene scene = new Scene(root);
        primaryStage.setTitle("Hello World");

        scene.setOnMouseClicked(new EventHandler<MouseEvent>() {
            @Override
            public void handle(MouseEvent doubleClicked) {
                if(doubleClicked.getClickCount() == 2) {
                    primaryStage.setFullScreen(true);
                }
            }
        });
        primaryStage.setScene(scene);
        primaryStage.show();
    }


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