I've got a fractal drawing application written in Cocoa.
Because the main window takes a significant time to render, I
wonder how I can do
to update the window from a separate Thread.
I know Carbon supports Multithreaded drawing, but what about Cocoa?
I'm using Mac OS X 10.4 Tiger.
You can draw from non-main threads, check the documentation:
You might know that the animations in buttons and progress indicators
on Mac OS X is driven by a thread called the "heartbeat" thread. It
most likely uses this type of implementation to do it's drawing.
