I guess you are talking about the TreeView chapter:
http://www.gtkmm.org/gtkmm2/tutorial/html/ch10.html
Please _tell_ us specifically about any part of the documentation that
is not clear. We can not guess everything.

Of course it's obvious that certain chapters have not been updated since
gtkmm 1.2, but some are clearly new chapters and I've asked for
feedback.

Again, tell us what part of this you don't understand:
http://www.gtkmm.org/gtkmm2/tutorial/html/ch16s02.html

The only thing that I don't like about RefPtr is the length of the
declarations - we have to add Glib::RefPtr< to the start of things.

Reference counting makes sense in _most_ places where RefPtr is used.
They are shared resources.

C++ has references, so we use them. It means that you don't need to
check for NULL pointers. C uses only pointers because that's all C has.
