JavaFX KeyEvent returns KeyCode.UNDEFINED

I created a simple JavaFX application that receives input from the user in a TextField. I attached the KeyTyped event from SceneBuilder to the controller. My function looks like this:

@FXML private void keyTyped(KeyEvent event) { System.out.println(event.getCode().equals(KeyCode.ENTER)); } 

This function always prints out UNDEFINED when I type the enter key. Any ideas on how to fix this? Other letters I type seem to have the same problem as well.

KeyTyped is a special event. It doesn't have KeyCode but has character set instead.

See example for letter 'a':

KeyEvent [source = TextField[id=null, styleClass=text-input text-field], target = TextField[id=null, styleClass=text-input text-field], eventType = KEY_TYPED, consumed = false, character = a, text = , code = UNDEFINED] 

and javadoc: ()

The key code associated with the key in this key pressed or key released event. For key typed events, code is always KeyCode.UNDEFINED.
