set-value

Sets the value (and displayed position) of the slider. (The control's callback procedure is not invoked.)

A slider's value can be changed by the user clicking the control, and such changes do not go through this method; use the control callback procedure (provided as an initialization argument) to monitor value changes.

• (send a-slider set-value value) -> void
      value : exact integer in [-10000, 10000]

  If value is outside the slider's minimum and maximum range, an exn:application:mismatch exception is raised.
