developer-old.gnome.org is not updated any more. The latest version of
the gtkmm tutorial is stored at
https://gnome.pages.gitlab.gnome.org/gtkmm-documentation.
I'm not super happy with it though. Trusting users to unparent from
both places without the framework enforcing or at least verifying it
is problematic.
Writing custom container widgets, derived directly from Gtk::Widget, was
more difficult in gtkmm3 than it is in gtkmm4. I think very few gtkmm
users ever did it. And like you say, it's far from perfect in gtkmm4._______________________________________________
