The item is invalidated by set-dialog-item-text, but is not redrawn until
the next update-event. Mouse events have higher priority than update
events.

I do something like this:

(defmethod scroll-bar-changed ((st e-text-scrollee) sb)
  (set-dialog-item-text st (princ-to-string (scroll-bar-setting sb)))
  (view-focus-and-draw-contents st))
