[gtkmm] Signal Connection Errors

["C.J. Collier" <cjcollier colliertech org>]

Hey All,

I'm having some problems with signal connection.  I've asked on #C++,
and they seem to think my code should work.  Would someone be so kind
as to help me debug this?

Code Attached.  Compile error below.

Thanks for the help,

C.J.

Compile error:
