I think you've been lucky. In Glade you are telling it about C types,
such as int, gchararray, but in gtkmm code you are dealing with C++
types. If those C++ types are similar then it might just work. For
instance, there may be an automatic conversion to
std::string/Glib::ustring. But even then I would not be very confident
about it.

It's hard for me to recommend this because it's likely to fail in weird
ways when using some C++ types.
