Gtk4 Gtk.ListView() Python example

@yPhil what did you discover was the reason your labels were empty?

I had forgotten the type of my custom class:

          <lookup name="name" type="ModelObject">
            <lookup name="item">GtkListItem</lookup>
          </lookup>

It works now just a few things left to set up (drag & drop, specifically) and then I’ll post a full example somewhere, for documentation’s sake.
