I convert my SortRow widget into a Gtk.ListBoxRow that has the same
functionality. The main benefit is that it looks nicer in the
Gtk.Popover compared to the Gtk.ListView that I had been using.
I also connect to the listbox "row-activated" signal so I can handle
clicking a specific sort row in the list. Clicking a disabled sort row
will enable it, and clicking an enabled one will reverse the sort order.
I think this is what feels the most natural to the user.
