[Interest] Can QML model specify a range including negative numbers? For example -180 to +180 ?

[Dmitry Volosnykh]

You'd better provide your implementation of TumblerColumn component.

Despite that fact, and assuming you somehow manage to know what value was
chosen, I'd suggest (as a quick attempt) to set model: 361, and the shift
values by -181.
