Each entry is still a constant either way. What I'd intended to provide is
a sort of a "remapping". I simply need stable names from the QML side, that
map to something (as "definitive" as this may sound), which "something" is
going to be mapped to vector indices on the C++ side. The latter (the
vector indices) I must assure are not changed from one version to the next.
While I do still need to provide some convenient API for QML to modify the
value(s). This in a nutshell is what I'm trying to do. Perhaps doing it
with an enum in QML is misguided, I was simply attempting to avoid defining
one such enum in C++ and needing to reship the compiled binary (to a
colleague). Perhaps my whole workflow idea is flawed, I guess.

If the names and values can change at runtime, you should use a

Yes, I suppose. Perhaps that's what I'm going to do in the end. Thanks for
the input.

If for each version of the program the set of names is fixed, and only

Actually the other way around (as, described above).

Kind regards,
Konstantin.
