The picture helps alot!
And your probably right... I do think it's complex so I'm probably
making it worse.
I'll study this, thanks
April.

Looks like I've opened a can of worms here.
Not at all. It's very straight-forward; if you find it difficult,
it's probably because you think it should be... it really isn't.
Here's a picture that should help:
<pastedGraphic3.pdf>
The origin of rectangle A is (2.0, 2.0), whilst its size is (4.0,
3.0). To get an NSRect corresponding to it, you'd do
NSRect rectA = NSMakeRect (2.0, 2.0, 4.0, 3.0);
Similarly for B and C you'd write
NSRect rectB = NSMakeRect (8.0, 3.0, 6.0, 3.0);
NSRect rectC = NSMakeRect (5.0, 7.0, 7.0, 2.0);
If the view (the outer box) is flipped, then you take the vertical
measurements from the top rather than from the bottom.
By the way what is Appkido? is it a third party frame work? or a
information source or a typo?
It's a *very* useful program that lets you browse the Cocoa
documentation. Here's a URL:

Kind regards,
Alastair.
