Description

The function range-set-sizes set the values in the range-pane range-pane for any value of start, end, slug-start or slug-end that is supplied as non-nil.

For each of start, end, slug-start and slug-end, if the value is nil or not supplied, the corresponding value in range-pane is not changed.

If redisplay is true (the default) then range-pane is redisplayed with the new values.

Notes

The values can be also set individually by the accessors (setf range-start) and so on. range-set-sizes has the advantage over the accessors that it causes fewer calls to redisplay.
