--- Comment #8 from Heiko Tietze <tietze.heiko at gmail.com> ---
Wrote on the KDE HIG:
* Use spin boxes for numerical input only. Use a list or option menu when you
need the user to select from fixed data sets of other types.
* Use a spin box if the numerical value is meaningful or useful for the user to
know, and the valid input range is unlimited or fixed at one end only. For
example, a control for specifying the number of iterations of some action, or a
time-out value.
* If the range is fixed at both ends, or the numerical values are arbitrary
(for example, a volume control), use a Slider control instead.
* For cases where the values are constrained at both ends and there large
ranges of integers (more than about 20) or floating-point values that require
precise control, consider providing both a Slider and Spin Box. This allows the
user to quickly set or fine-tune the setting more easily than they could with
the slider control alone.

The pure edit is not better as it gives no clue about numerical and constrained
input. So odd yes, but better than ordinary edit.
