Updating your UI and forcibly waiting before continuing JavaFX

Question

I show here an image of my welcome scene.

The current behavior of the Create New Project button is shown here:

Stage stage = (Stage)(         


        

Answer 1

You should try adding in ControlsFX this will help.

You can do the following:

   Service<T> service = new Service<T>(){
       @Override
       protected Task<T> createTask() {
       return new Task<T>() {
          @Override
          protected T call() throws Exception {
        //Do your processing here.                      }
          };
      }
    };
    service.setOnSucceeded(event -> {//do your processing});
    service.setOnFailed(event -> {//do your processing});              
    ProgressDialog pd = new ProgressDialog(service);
    pd.setContentText("Please wait while the window loads...");
    pd.initModality(Modality.WINDOW_MODAL);
    pd.initOwner(stage);
    service.start();

This will put your code on the background thread. ControlsFX dialogs start and stop with the service.

Answer 2

Instead of sleeping the thread, use a PauseTransition and load your new scene after the pause has finished.

createNewProject.setOnAction(event -> {
    statusText.setText("Please wait...");
    PauseTransition pause = new PauseTransition(
        Duration.seconds(1),
    );
    pause.setOnFinished(event -> {
        Parent root = FXMLLoader.load(
            getClass().getResource(
                "/view/scene/configure/NewProjectConfigureScene.fxml"
            )
        );
        Scene scene = new Scene(root);
        stage.setTitle("Configure New Project Settings");
        stage.setScene(scene);
        stage.sizeToScene();    
    });
    pause.play();
});

The above code assumes you have just a single stage, so you resize your "Welcome" stage to become the "Configure New Project Settings" stage.
