Hi Ross,
Thanks for your reply,

I've googled for a solution, found nothing. I tried making it by
observing the NSViewFrameChangedNotification of the NSTextView from
it's parent, and resizing, but this is more tricky then I imagined.
I think you are on the right track. You might want to look at these
threads:

I took a look. The code you posted in the second thread (having a
switch to stop recursive resizing) makes sense. I was thinking along
similar lines.
At the bottom I pasted my current code on this. There is a problem
though, but one which seems to be connected to having an NSTextView
not directly embedded in a scroll view, not so much with my code... In
short, NSTextView does not react to the parent view resizing in the
standard way (which is easily tested in IB). Perhaps it assumes it is
directly embedded in a scroll view. This makes it hard to reconcile
with what I am trying to do, even if my added code works OK.
Any thoughts?
As as side question, it seems that an NSTextView has some margins
that separate the text from it's outer edges. This makes sense when
the NSTextView is in an NSScrollView, but makes it difficult to
align the text view when it is not. I can't find any documented API
on controlling this. Is it possible?
I think you want to look at setLineFragmentPadding: in
NSTextContainer.
That sounds like the right thing, thanks...
