I'm just wondering how you use MouseWheelEvent? It's the event to use when the event type is MouseWheelMoved right?

Is it that negative is scrolling downwards and positive is upwards? Is it relative? So the more scroll the higher/lower number?

Right.

I never remember :lol:
You'd better test it

Yes, everytime you scroll you'll get a value starting at zero (so unless you scroll very fast, you'll probably only get 1 and -1).

Aight I was right. I tested it and negative is down and positive is up.
