Even when used as a bitfield, I'd still argue it is not good design. (It might be an expedient hack to get something done, and if you are happy with that as a solution, great.) It overloads the tag to imply control behavior/appearance, while at the same time preventing users of your class from using the tag for its original purpose. (Yes, I realize that the the user of the custom table view is the same person as the provider of the custom table view.) - Jim _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
