Re: [cgkit-user] Cursor mask for two tablets simultaneously?

[Matthias B. <mat...@gm...>]

Hi Ryan,

I have never worked with two tablets at the same time, so I'm not sure
what the correct way of doing this is.
But if you already have two separate contexts that each is connected to
a different device, isn't that enough to differentiate the events?
Why would you still need the movemask? (I'm actually not sure if the
movemask is used to distinguish between devices)

I'm afraid if you need more details about the individual fields of the
context or packet object you'll have to check the actual wintab
documentation (see section 7.3, for example):

Cheers,

Matthias
