I can't say that I have dealt with the exact situation you write of, however,
my best idea/hint is to point you to the NSTextContainer class. The NSTextView
is composed of a lot of complicated machinery and I believe you might have to
dive below the topmost layer (i.e. NSTextView itself) in order to achieve your
desired results. Your documentView (the textView) will continue to size its
width according to the contentView, but the internal "view container" for the
rich-text object being displayed inside of the textView will need to be told
not to maintain this same, width-sync'd relationship.
(I repeat, this is only a somewhat educated stab-in-the-dark, i.e. I have used
NSTextContainer's setWidthTracksTextView method. More informed people should
still be encouraged to reply.)
Good luck.
