There is no reason to subclass his control to attach an int value (or more generally to track which instance a particular control is). See NSControl tag/setTag. They allow you to do exactly what he wants.
Well, not quite - tags store ints, whereas a Carbon Control refCon is *typically* used to store a pointer or Handle, so I didn't mention it to avoid misleading the OP into thinking that tags and refCons were semantically identical.
Additionally if you want to attach some sort of object (say a string or something more complex that needs to be retained) see representedObject/setRepresentedObject. It's part of NSCell not NSControl, but most of the complex controls have a NSCell subclass anyway (i.e. an NSButtonCell is attached to every NSButton).
Right, I'd overlooked that one. This sounds much more appropriate.
