Sets the function that is called when the slider button stops moving.
The first parameter to the function is the slider object
that triggered it. This slider's "getValue()" method gives the
actual value of the slider when it did the function call. This function is
called both when the slider button has been dragged,
and when the slider has been clicked in a different place.
