Note however, GObject callbacks don't mix very logically
with C++ pass-by-reference argument style.
You can't pass a std::string variable as the last argument of
g_signal_connect() as you would in direct function call, you
have to pass a pointer, and once you do that, it doesn't
make sense to declare
MessageInfo(std::string &msg)
instead of
MessageInfo(std::string *msg)
