define "the visible objects" when what you have at hand is not a visual object at all, but an object whose job is to make an image from some data. Clearly those who think this is trivial or easy have not actually tried doing this, and are not understanding what the problem is here. Of course it's easy to call -setQueuePriority:, that isn't the problem. The problem is how to decide what it should be set to, when. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
