Gtk4 / listview questions

I’m actually working on this right now. I’m porting Gtk3::Ex::DBI ( perl / gtk3, supports both ‘datasheet’ and ‘form’ style widgets ) to python and gtk4. I’m getting quite close, but I’m now confused about the gtk4-specific stuff - in particular around changes to the liststore and listview. In gtk3, we had to use GtkCellRenderer, but I see that this is now not required, and we can use ‘regular’ widgets. I have been looking for the past hour for a short example of doing this ( in python ), but I haven’t seen any yet - the tutorials I’ve found still use GtkCellRenderer. Anyway, I’m happy to collaborate on this.

Anyway, are there any examples around that pack regular gtk widgets into a listview?
