- # Increment --
- # This procedure is invoked to increment the value of a scale and
- # to set up auto-repeating of the action if that is desired. The
- # way the value is incremented depends on the "dir" and "big"
- # arguments.
- #
- # Arguments:
- # w - The scale widget.
- # dir - "up" means move value towards -from, "down" means
- # move towards -to.
- # big - Size of increments: "big" or "little".
- # repeat - Whether and how to auto-repeat the action: "noRepeat"
- # means don't auto-repeat, "initial" means this is the
- # first action in an auto-repeat sequence, and "again"
- # means this is the second repetition or later.
