NSRectFill() is a C function, not part of any class e.g. NSView.
aRect is simply a struct which specify location points (doesnt
contain reference of any window). How the function knows about the
drawing surface, in which window/surface to paint? Does it
implicitly make use of some self pointer? If so, then, what if this
function is not called from inside a simple C function then there
will not be any self pointer?
Did you read my previous message?
