Hi again, >From an earlier thread I found the columnview demo ( https://gitlab.gnome.org/GNOME/gtkmm/-/blob/master/demos/gtk-demo/example_listview_columnview.cc), which was exactly what I needed!
In case anyone runs into the same problem as I did, my mistake was using `std::make_shared` to create new instances, when I should have been using `Glib::make_refptr_for_instance`.
