The menu system is a tree structure, but each screen is a flat list.
So yes, you’d need a list, not a tree.

This way of organizing information is sometimes called a property
list. Initially a two-column table seems to be an obvious
implementation, but it suffers from this particular problem when
horizontal space is limited.

How long is that NATID? I see 13 digits and an indication there are
more. Is there any convention to split that into groups, like you see
1234 5678 9012 3456 on bank cards? That would help readability. At the
same time, it introduces natural points to wrap lines.

    Part Number         71-000000
    Version                47.11D
    Build Number          kk-5910
    NATID          8988 1697 0000
                        0000 0013

Also it looks like the left column is too wide. The longest visible
label is Build Number but the NATID value starts way to the right. If
wrapping is not an option, I’d try to make the labels shorter. In a
pinch, “Number” can be shortened to “#”.

Lastly, for this screen, you could skip the list box altogether and
organize the property list as a single column GtkBox, where each child
is a single row GtkBox, with the label in the left cell and value in
the right cell. This approach takes you off the listbox grid; you can
have one row with a long label and a short value, and another row with
a short label and a long value.

    Version                  47.11D
    Build Number            kk-5910
    NATID  8988 1697 0000 0000 0013

Sorry for turning it into a “what you want is wrong” discussion :)
