WM_GESTURE: retrieve all fingers?

I'm using WM_GESTURE to manipulate my 3D scene, and i'd like to perform different gestures if i'm panning with 1 finger or if i'm panning with 2 fingers.

I know that i could get the touches and do everything by myself, but i like to use gestures because it interprets correctly all the touches and transform them into gestures.

How can I, after receiving a GID_PAN event, detect wether the user is using 1 or 2 fingers and its positions?

thanks!

Solution

  • I've found out the answer.

    After trying to figure it out all day before posting a question here, now i've found this link which explains the function of ullArguments. It will store the distance between the fingers when i'm panning. so if it's a single finger panning, ullArguments will be 0; otherwise, it will be a positive number.
