>Subject: [REBOL] Using the check-box in REBOL/view
>Can someone give me an easy example that uses a check-box to change a
variable from "1" to "2" and >label the variable?
The view VID check-box, as it is currently implemented, works as a flag. It
does not trigger an action when its state is changed.
The FAQ has for an example of using the check-box
http://www.rebolforces.com/view-faq.html#section-2
However if you want a check-box that can trigger an action. There is a
example on the RF rebsite (in the style section) called check-style.r on the
RF rebsite shows how to do that.
REBOL [] do http://www.rebolforces.com
The basic script is at the end of this email..
