You can't.
The sliders you are talking about are created by webkit (from the page source 
aka html) and are not QAbstractSlider instances. Thus you cannot access their 
signals.

However it should be possible to achieve this via javascript - by registering 
an eventListener for the scrollbar that in turn calls some c++ method.
But sorry - no codesnippet available:-(
