I am (still) working on my todo application. While I'm thinking about where to place the save button, I figured I would add a keybind to save too.

I added the key bind in my main class like this:

final KeyCombination keyComb1 = new KeyCodeCombination(KeyCode.S,
        KeyCombination.CONTROL_DOWN);
scene.addEventHandler(KeyEvent.KEY_RELEASED, new EventHandler<KeyEvent>() {
    public void handle(KeyEvent event) {
        if (keyComb1.match(event)) {

        }
    }
});

However, the stuff I need to do on the CRL + S is in the controller class. How can I bridge this or make it so the controller can get this information?

Edit: I do not want to pass any info. Just the fact that the event happened.

Edit 2.0: I have solved the issue. The solution was to get the controller instance at the start, save it and when the event was called, use the said method.

Call the controller class from the listener? – Jacob B. Apr 06 '18 at 16:16
This is the main class where the scene is ini'd. How could I call the controller class from there? – Matthew L Parks Apr 06 '18 at 16:21
Inside the listener, write something like this: ControllerClass.saveDataMethod(); (obviously replace each with their actual names) – Jacob B. Apr 06 '18 at 16:47
Like a static inside the contoller? – Matthew L Parks Apr 06 '18 at 16:47
Yeah, that would be optimal – Jacob B. Apr 06 '18 at 16:48

Why would you make it `static`? That makes no sense: you wouldn't be able to access any of the UI controls from a static method. Just get a reference to the controller *instance* and call the method from the event handler. – James_D Apr 06 '18 at 16:57
