UI upgrade and forced wait before continuing JavaFX

Question

Here I show an image of my welcome scene.

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

Stage stage = (Stage)((Node)event.getSource()).getScene().getWindow();
stage.hide();
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.show();

Explain it with the words: button pressed → I get the scene → hide the current scene → switch the scene to a new scene → re-display the scene. This behavior works.

I am new to GUI programming, so please bear with me explaining what I need.

:

statusText.setText("Please wait..."); // statusText is the "loading message"
Stage stage = (Stage)((Node)event.getSource()).getScene().getWindow();
try {
    Thread.sleep(2000);                
} catch(InterruptedException ex) {
    Thread.currentThread().interrupt();
}
stage.hide();

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.show();

Answer 1

PauseTransition .

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();
});

    ProgressDialog pd = new ProgressDialog(service);
    pd.setContentText("Please wait while the window loads...");
    pd.initModality(Modality.WINDOW_MODAL);
    pd.initOwner(stage);
