I think probably something silly ... bear in mind that a views
coordinates are relative to the view it is placed in.
I suspect that you meant the coordinates for the textfield to be
pad,pad rather than r.origin.x+pad,r.origin.y+pad

D'oh!  I really thought I'd checked that the origins coming in there were 0,0.
I just figured I'd want them if I moved to another frame of reference (like
if I ditch views).

So the NSRect that is passed in is the frame in terms of the containing
coordinates (which makes sense I suppose, otherwise you could just send
a size :-)) and what it buys you is precisely what I'm trying to do(!), the
ability to draw directly in the view, which is done in terms of *that*
coordinate
system.  And the view having its own frame of reference is more or less just
sugar that makes it a handy weapon to point at your feet ;-)

My consistency hobgoblin is now hopping from foot to foot :-)))

Thank you, thank you very much!  That was something I wasn't going to see
even though it was staring me in the face! :-)

Regards,
Paddy
