Hi Graham,
Thanks for your answer.
Let me explain current scenario.
I have two input device from which i am getting raw coordinates(x,y).
When there is only one device i can draw paths using x,y coordinates. All
things are working fine.
Now if user writes using two input device on one surface simultaeously then
it should draw two individual path depending on (x,y) coordinates from
different input device.
so what is your inputs on this situation?
Thanks & Regards,
Ravi.

Any help would be appreciated.
You don't say what you want to stroke, but let's assume a NSBezierPath.
// ...set up stroke parameters for stroke 1 here ...
[path stroke];
// ...set up stroke parameters for stroke 2 here...
[path stroke];
In other words, you just draw one stroke then the other.
If you really want to stroke two lines or other paths "simultaneously"
(not sure what you mean by that either - nothing is truly simultaneous),
then you can combine paths into one bezier path object and stroke it all
at once. However, you can't apply separate stroke parameters to different
parts of the path this way.
