There is probably a bug in the way GooCanvasRect is wrapped in 
Goocanvas::Rect. That's why virtual functions are not called. See

You can file a bug in Bugzilla, if you like.

Are you talking about the gtkmm tutorial, 
https://developer.gnome.org/gtkmm-tutorial/stable/?
It does not contain any examples from Goocanvasmm. All examples in the 
tutorial have been tested and found working. There's no reason to delete 
anything from the tutorial, just because there is a bug in a class that 
is not mentioned in the tutorial.
Or have I jumped to conclusions? Are you talking about some other 
documentation?
