Yes, but what does that have to do with anything? There is no error when
you use Glib::RefPtr<Gtk::TreeStore>

Why do you want to have a pointer to a row?

You get rows by dereferencing iterators, like so:
Gtk::TreeModel::Row row = *iter;

Likewise, in a std::list<int>, you would not do.

int* pValue = 1;
std::list<int>::iterator it = *pValue;

You don't get iterators by dereferencing rows, or "pointers to rows". You
get iterators from the TreeModel.

There are plenty of gtkmm TreeView examples - you can see the source in
the gtkmm book online.
