There are many pure C++ applications in the world that implement undo. You don't have to use the Cocoa undo at all if portability is important. Implement undo in C++ using the Command pattern or whatever technique you want. Then integrate Cocoa GUI support via menu items etc. for invoking the C++ undo.

I realize the Cocoa provides snazzy undo/redo support that is difficult to mimic cleanly in C++. That's one reason many people like Objective-C and Cocoa.

The other alternative is to write your "portable" code in portable Objective-C. _______________________________________________
