In my app, I need a worker thread to continuously update a progress
bar. Basically, it tells it that it's done scanning a directory. So,
in the worker thread, I've set it up to post a notification with a
`userInfo' dictionary.
I've read Apple's docs on the subject posted here:
http://developer.apple.com/documentation/Cocoa/Conceptual/
Notifications/Tasks/Threading.html
I've implemented the threading support in the observer object as
described in the document, but for some reason, the
``handleMachMessage" delegate method is never getting called!
Everything gets initialized So of course, the notifications aren't
getting dispatched to the proper thread. Everything works fine up
until that point. The worker thread is posting the notifications, and
the proper method is getting them in the observer. But they're not
being enqueued correctly.
Also, I've set the progress bar in question to use threaded
animation. Will this cause problems updating it in this fashion?
Any help is greatly appreciated.
