Handling multitouch in Windows (like for Surface Pro)

Recommended Posts

Hi all, I have what I hope is a quick and easy question!

 

On iOS, multitouch is handled by giving each finger touch an ID... it's real simple, as you receive the touch callback, you just query for the ID too.

 

How is this done in Windows 8, for touch devices?  When I intercept WM_MOUSEMOVE or WM_LBUTTONDOWN, how can I determine the ID of the touch so I can properly handle them without confusing the two?

 

Thanks!

John

Thank you very much... I wasn't able to find this information anywhere else.  I'm infuriated that they made this into a whole new input stream, though... it's going to be a lot of crazy work to fold this into my habits.
