I have a sparks Hslider with 2 thumbs. I want that, when the user set a value for the second thumb, an event is fired so that actions can be performed. But how can you fire an event when exactly this happens?
I know of the function "change" but this will fires ones something changes in the timeslider. But as the user can change also the other thumb, I want it to fire only when the thumb with index 1 has changed.
