I'll still tell you to use gtkmm. Its not too late. Its a much better idea.

without knowing what the thing you set pb->_callback to is, there is no
way of knowing whether this is a legal statement. it doesn't seem
impossible from your design that you've attached a member function to
pb->_callback, for example. this cannot work. but like i said, i don't
know what you're trying to call.
