title: Change scene in full screen JavaFX
body: <p>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?</p>
  
  <p>Here is my code </p>
  
  <pre><code>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&lt;ActionEvent&gt;() {
  
          @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);
  
          }
      });
  
  
  }
  </code></pre>
  
  <p>}</p>
