JavaFX - Undecorated Windows hat einige Probleme

Question

Ich machte ein undekorated Fenster in JavaFX, aber dann verschwanden alle meine Komponenten.

Mein Code:

public class Main extends Application { 

    private double xOffset = 0; 
    private double yOffset = 0; 

    @Override 
    public void start(Stage primaryStage) throws Exception{ 
     Parent root = FXMLLoader.load(getClass().getResource("sample.fxml")); 

     primaryStage.initStyle(StageStyle.UNDECORATED); 
     primaryStage.setResizable(false); 

     root.setOnMousePressed(new EventHandler<MouseEvent>() { 
      @Override 
      public void handle(MouseEvent event) { 
       xOffset = event.getSceneX(); 
       yOffset = event.getSceneY(); 
      } 
     }); 
     root.setOnMouseDragged(new EventHandler<MouseEvent>() { 
      @Override 
      public void handle(MouseEvent event) { 
       primaryStage.setX(event.getScreenX() - xOffset); 
       primaryStage.setY(event.getScreenY() - yOffset); 
      } 
     }); 


     primaryStage.setTitle("Hello World"); 
     primaryStage.setScene(new Scene(root, 600, 400)); 
     primaryStage.show(); 
    } 


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

    public void init(){ 



    } 

} 

und das ist mein FXML Datei:

    </graphic> 
    <font> 
     <Font size="24.0" /> 
    </font> 
</TitledPane> 

und das ist, wie es in Szene Builder aussieht:

Danke im Voraus, um mir zu helfen: D Einen schönen Tag haben

Answer 1

Die Lösung für Ihr Problem besteht darin, etwas wie ein AnchorPane als Wurzelknoten zu verwenden. Ich habe keine Ahnung, warum das passiert.
