A method handler error is not available in FXML (it only works if I create a method with the parameter "Event" or "ActionEvent")

Question

I want to call the handler method when I press any key on the keyboard, and then get the key character pressed. So I wrote this line for the button in the fxml file:

<Button fx:id="button" layoutX="126.0" layoutY="90.0" onKeyPressed="#handleButton" text="Test!" /> 

When any key is pressed, this should call the handleButton method in the controller class and pass the KeyEvent parameter to it. So I wrote this method inside it:

 @FXML private void handleButton(KeyEvent event) { System.out.println(event); } 

In the fxml file, NetBeans shows the error "The handler method is not available. Publishing or annotation using @FXML.", Which I already made.

As soon as I switch from private void handleButton(KeyEvent event) to private void handleButton(Event event) , NetBeans stops showing errors and the application runs.

On this page, I found an answer that uses onKeyPressed exactly the same as me, so I'm really confused why this is not working in my case.

Thanks for your help,

You probably imported the wrong KeyEvent . It should be javafx.​scene.​input.KeyEvent .
