should i re-post the code snippet?

If you're going to us C++, check out the GTK-- C++ bindings for GTK. 
GTK-- lets you define callbacks to member functions in the same class.  

Under the hood, though, you'll have to pass a pointer to your class
(this) as the data parameter to the static method.  If you wish to pass
other pieces of information, you'll need to make a structure with the
this pointer plus the extra params you want to send the call-back, and
pass that to the g_connect call.

Honestly, though, if you're bent on wrapping GTK calls in C++ objects,
you're far better off using GTK-- which has a really nice object model
and the signaling interface is really handy, allowing extra arbitrary
parameters to be passed to a call-back (g_connect only allows one extra
parameter).  See http://gtkmm.sourceforge.net.


thanks for the help,
