[Qt-qml] How to quickly scroll through a ListView with a large number of elements?

[Todd Rose]

Let's say I have a ListView with 500 or 1000 elements.  The model is
fast and the delegates are small.  Scrolling is relatively smooth, but
it takes an eternity to flick scroll from the top of the list to the
bottom.  Is there any way to increase the vertical scroll speed?
Ideally I would like to add a scroll bar item on the right side and
allow the user to drag that up/down in order to quickly zoom to
locations in the list.  Is this currently possible?

The native address book application on Symbian^3 would be a good
example of what I'm looking for.  The floating 'A', 'B', 'C', etc.
indicators would be nice to have but aren't necessary.  Fast scrolling
through a large list is really all I need.

Thanks in advance,
TC
