Answer 1

You should pass function which applying one parameter of type ActionEvent:

val button = new Button()
val inputController = new InputController()

def handler(h: (ActionEvent => Unit)): EventHandler[ActionEvent] =
  new EventHandler[ActionEvent] {
    override def handle(event: ActionEvent): Unit = h(event)
  }

button.setOnAction(handler(inputController.handleFileSelection))
