Cells are mostly designed, as far as I can see, to relieve the view of a repetitive drawing task. Where they have an editing function, that's handled by the Field Editor, another view. > Unfortunately, I'm embedding these in an outline view, my current thinking is > to subclass NSOutlineView and hack my own responder events to talk to my > cell, but it seems a bit of a hack – it embeds part of the semantics of my > cell in a class elsewhere, and stops the cell being composible in other > scenarios.

You could just pass everything to the cell, but then it wouldn't work the same in a standard control. There is no defined protocol beyond the usual control <--> cell methods which allow you to, e.g. start and stop editing, but do not go further down to individual key events, which are handled by the Field Editor. There are further interactions between the Field Editor and the cell though, maybe your cell could use the FE in a standard way for editing? I've made a few NSCell subclasses in my time, and every time it was a deal of trouble. In your case if you want to use NSOutlineView as a host you'll probably have to accept the hassle, or try to make your cell fit in a more standard way. Sorry the advice is rather vague - every case seems to be different. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
