Bill,
Thanks for the pointers. I'll see if I can track down a copy of your
book, although it could be tricky down here in Australia. On the other
hand, there's always Amazon. :)
Basically, it seems to me that the
undo manager is designed to work with straightforward, by-the-book
Cocoa
applications, and as soon as you try to do something unusual you run
into
the wall of assumptions made by the undo manager.
What I'm trying to do is not unusual at all, or at least I wouldn't
have thought so. The example that I used to illustrate the problem in
my original post is a very simple Cocoa app using common Cocoa
behaviours.
I don't mean to suggest that this is the best way to attack your
problem. In
fact, in my experiments I never ran into the problem you've
experienced of
getting an undo action for every character. So I suspect you need a
fundamental rethink of your approach.
That's the problem: I can't think of an approach that solves for all
three examples I gave in my original post.
