I'm glad you mentioned that.  I was wondering about the cost of pointer 
vs local object.  Just looking at your example though would I really 
need to define _chips as a vector to pointers or would this work as well:

typedef std::vector<Gtk::ToggleButton *> chiprow;
std::vector<chiprow> _chips;

That may compile but would it be better to use pointers in the 2nd 
vector as well?

Thanks for all the help guys.  I'm glad I asked this question.
