[REBOL] Re: Iterated check box anomaly (resend) - now, the ROTARY!

I am still trying to figure it out myself, but just quickly,
this might do enough what you want:
rebol [
Title: "Iterated Rotarys"
File: %iterated-rotarys.r
Date: 6-May-2002
Version: 1.0.0
Needs: [view]
Author: "Anton Rolls"
Language: 'English
Purpose: {Make rotarys in a VID list work}
Usage: {}
ToDo: {
- iterated rotary doesn't react quite the same as a single rotary:
- single rotary shows next value while mouse button down
- can't go backwards with alt-down (right mouse button)
- depends on face/state
}

1.0.0 [6-May-2002 {First version inspired by a post by Geza Lakner

ROTARY!" on 6/5/2002} "Anton"]

Notes: {
adds a new facet word: 'my-count to the rotary
I am theorizing that to make all faces iterateable,
we could add a new facet, eg. 'save-data, which is an object!
with the facets that need to be stored (eg. data, text etc.)
The list should get/set this object in the supply code.
This get/set code will always be the same, making it trivial
to implement iterated faces on any style.
We would need to modify all the styles so that the appropriate
data is stored in save-data.
