I think (but I am not sure), that the situation is the following:
libglademm can't do the same thing in C++ as libglade does in C due to the
name-mangling of the C++ compiler (as opposed to no name mangling in C).
That is why libglade can find the names of the callbacks in a C program
(although it is a runtime mechanism). Libglademm can't do the same thing
in C++ since it does not know what the mangled names look like.

I hope, that my info is correct.
