How to get stage from controller during initialization?

Solution
You can get the instance of the controller from the `FXMLLoader` after initialization via `getController()`, but you need to instantiate an `FXMLLoader` instead of using the static methods then.
I'd pass the stage after calling `load()` directly to the controller afterwards:
FXMLLoader loader = new FXMLLoader(getClass().getResource("MyGui.fxml"));
Parent root = (Parent)loader.load();
MyController controller = (MyController)loader.getController();
controller.setStageAndSetupListeners(stage); // or what you want to do
Problem
I want to handle stage events (i.e. hiding) from my controller class. So all I have to do is to add a listener like this: ``` ((Stage) myPane.getScene().getWindow()).setOn*whatIwant*(...); ``` But the problem is that initialization starts right after this code: ``` Parent root = FXMLLoader.load(getClass().getResource("MyGui.fxml")); ``` And before this code: ``` Scene scene = new Scene(root); stage.setScene(scene); ``` Thus `getScene` returns null. The only workaround I found by myself is to add a listener to `myPane.sceneProperty`, and when it becomes not null I get scene, add to it's `windowProperty` my listener handling which I finally retrieve stage. And it all ends with setting desired listeners to stage events. I think there are too many listeners. Is it the only way to solve my problem?
