JavaFX2 Scenes in separated classes

Question

Is there a way to keep my scenes in separate Java files in a JavaFx application? I tried something like this:

public class MyApp extends Application 
  {

    private void init(Stage primaryStage) 
    {
        Group root = new Group();
        primaryStage.setResizable(false);
        Login login = new Login(root, primaryStage); // from another file
        primaryStage.setScene(login);
    }

I have to close my login scene after authentication and load another scene from another file, so I'm passing the primaryStage as a parameter for my login Scene to use stage.close()

Is there a better way for doing that?

My Login scene file

public class Login extends Scene 
 {
    public Login(Group root, final Stage stage) 
     {
        super(root, 265, 390, Color.web("EBE8E3"));

Is there another way to reference the current scene stage?

Answer 1

You don't have to pass the stage as a parameter. The stage is always available from the nodes of the current scene !

scene.getWindow()

This returns the current stage/window of the scene !
