That, but I also don't see why the two layers would need to read the data separately. For example, their delegate can be the one to fetch and read the data and create the path from it, then save that CG path. When either layer draws, it would simply use that path. It'd be trivial. -- Seth Willits _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
