["Faria, Sydney C" <sydney faria pw utc com>]

I used one cb function to handle fifty buttons by sending an integer to the
cg func using GINT_TO_POINTER & GPOINTER_TO_INT as the passed parameter:
then used a switch in the cb func.  I also had a need to use more data in a
cb func and had to make a structure with the needed data and passed a
pointer to the structure.
