I asked about this awhile back, and received instructions on changing
the background of a square button, which worked for my purposes. What
sort of button are you trying to change?

Generally, you don't. The main reason is that Apple does not want us
to do
that. The technical one is that, so far as I know (did not check
myself!)
actually a bitmap image is used for the background, and thus the
change is
non-trivial.
It seems like such a simple thing but it doesn't want to change. It
seems like a lot of things have the setBackgroundColor member function
but NSButton doesn't.
Check the archives -- some time ago (a few months, IIRC) this was
discussed and even some sample code I kind of recall was posted. The
trick
is to get the image, and change its pixels' colours. Non trivial of
course
-- the more reason not to do that (unless really inevitable).
