Although I'm still interested in NSOutlineView, I believe that an NSBrowser would provide a more appropriate interface. However, looking at the write-up in "Cocoa Programming" (Anguish, et al), I'm not at all sure I'll be able to battle my way to working code.
If anyone has (or is willing to develop :-) a trivial example of a multi-column NSBrowser, I'd love to see it. Until then, I'll hack on one and submit the usual partly-baked code snippets for help and comments. -r -- email: [EMAIL PROTECTED]; phone: +1 650-873-7841 http://www.cfcl.com/rdm - my home page, resume, etc. http://www.cfcl.com/Meta - The FreeBSD Browser, Meta Project, etc. http://www.ptf.com/dossier - Prime Time Freeware's DOSSIER series http://www.ptf.com/tdc - Prime Time Freeware's Darwin Collection
