Right, as we (Florian and I) explained in an earlier response to this
thread [1].

Do not use GtkTreView, deprecated in 4.10 and will be removed from
Gtk-5. Instead, carefully read this section (till the very end):

	https://docs.gtk.org/gtk4/section-list-widget.html

You must get (very) familiar with the upstream namespace api you are
using - by that I mean: you should install the GNOME lib doc carefully
read and understand its introduction material, and consult it as you
are developing your app (also carefully read and understand the GOBject
introduction material as well).

The g-golf naming conventions are explained here:

	https://www.gnu.org/software/g-golf/manual/html_node/Naming-Conventions.html

You import from a namespace, and by GI convention, the
gi-import-by-name second arg 'drops' the namespace - see any g-golf
distributed example, in particular adwaita-1-demo  (adw-demo-init)
module.

[1]	g-golf guix users - how to run the examples

	guix shell g-golf -D g-golf gtk --no-grafts
	$(guix build g-golf-gtk-4-examples)/share/doc/g-golf/examples/gtk-4/.hello-world-real

	[ *-real are the upstream version of the example

So when working on your own app:

	guix shell g-golf -D g-golf gtk [libadwaita] --no-grafts
	cd your/app-devel/path
	./my-app
