Description Carlos Garnacho Parro 2012-01-25 13:07:30 UTC

With XInput >= 2.1, the valuators with a matching XIScrollClassInfo report absolute values in events, so if you scroll down you get say 1000, and if you scroll then up a bit you get 900.

To my understanding, these valuators should provide actual deltas, instead of leaving delta calculation up to clients

no, we actually have to provide absolute valuators since XI doesn't allow us to report relative values in valuators. This is basically the reason for RawEvents.

_might_ be possible to tack on for XI 2.3 but don't wager your bets on it.
