In response to the question posted by Rudi Sherry earlier today, I
looked at a document-based program I've been working on to remind
myself of what I did regarding keeping the text current. Separately,
in the same program, I update a hierarchical menu so that it shows
the names of all the open document windows. I do this by using a
menuNeedsUpdate delegate. In my code for this method, I put a brief
message in the run log (for debugging purposes). Much to my
surprise, this shows that menuNeedsUpdate gets called every time I
type into a document window, even though in Interface Builder, the
delegate is connected between the menu that I want to update and my
AppController, and would seem to have nothing to do with typing in a
document window. Obviously, I don't understand something (not
unusual for me). I reread Anguish et al. on delegates and still
don't understand why typing in a document window would cause
menuNeedsUpdate to be called.
