I can't really tell for sure from your code how it's even supposed to 
work.

I think your whole approach may be doomed.

Your class needs to be a subclass of GSVbox or GSHbox ... you are trying 
to
make it act like either using delegation, and that just won't work.
Your class needs to be a subclass of NSView, and other parts of the 
system
need to refer to it directly (views are held in a hierarchical structure
within each window).

I think I'd simply have two classes ... one for vertical and one for 
horizontal
layout.
