You can have a look at DistributedObject. I think you can publish a drawer object in your drawing thread and then, just call draw fro your main thread.

DO might be overkill for this scenario. The background thread really just needs to run a while() loop that waits on a condition-lock, then draws. The main thread's -drawRect: method just sets the condition on the lock to trigger the background thread.


If more information needs to be passed to the thread, you can use a producer/consumer queue, but unfortunately Foundation doesn't come with one of those built-in; there must be source code for one lying around, though.
