spinner component

> From my personal impression, the more common form of Spinner is the editable kind, so I would certainly consider this to be part of the spec for a JavaFX Spinner control, and one that would need to be supported in a first release.

If editable means "select by typing" I can see how that would work.

Since the data is provided by the data provider, all these things should go there. The spinner just asks the DP for the next index, if that is +1 or +16,327,587.24 is up to the DP.

Already set up, part of the data provider (there currently is an abstract integer DP, and a list DP which uses that again with 0 and list size as the bounds).

CSS?

Ok, needs to be added.

Hm. Naturally there is a difference between a spinner and a timepicker. A spinner has one set of arrows, time or date selecting often has one above and below every digit. IMHO this is very specific for a timepicker.

Naturally it is quite possible to do this, after all clicking on the minutes+ arrow, only means setting the step size to 60 (if we're showing seconds) and doing a "next". But I feel a time/date picker is such a specialized case, I would not force those requirements onto a regular spinner.
