So in your example, the difference is that I can run the NSApp in the main thread (Thread B). And it's usefull because I have no access to the thread A. With GNUstep Cocoa, in the plugin I create a pthread (thread B) and then I am registering it to be the main thread. Then I am running NSApp in there. > > > In this way no performInMainThreads are borken, and it's a solution to my >> problem. >> > > It's still not clear what your problem is. > > What exactly is it that are you trying to do on Mac OS X?

(whereas on GNUstep I have to call GSRegisterCurrentThread) So the final question: is there a way to make [NSThread isMainThread] return YES in a thread different that the main thread of a process, on MacOSX ? > but we need to know what the problem is (not how you think you want to > solve the problem). Maybe you did not get my first email where I explained everything (dated: 8 juillet 2009 10:34 am, Paris. I can re send it if this is the case) > > > Scott > > Sincerely Julien _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
