Treeviews are being deprecated in GTK 4.10. Move to the new proposed approach:

The new approach has virtues but kinda sucks at this stage.

Hard to capture double click: https://gitlab.gnome.org/GNOME/gtk/-/issues/4364

Height isn't easy to fix. (Solved with style class data-table)

Seems work in progress...🤷

Drag and drop for rows also has problems:

A workaround would be, adding some buttons for sending the rows up or down but even this might be a challenge with the new api. Need to check
