-    \example scroller/wheel
-    \title Wheel Scroller Example
-
-    The Wheel Scroller Example shows how to use QScroller, QScrollEvent
-    and QScrollPrepareEvent to implement smooth scrolling for a
-    custom Widget.
-
-    \section1 Basics
-
-    The QScroller class is the main part of the smooth scrolling
-    mechanism in Qt. It keeps track of the current scroll position and
-    speed and updates the object through events.
-    QScroller will get touch events via the QFlickGesture.
-    It will query the target object through a QScrollPrepareEvent for
-    the scroll area and other information.
-    QScroller will send QScrollEvents to inform the target object about
-    the current scroll position.
-    The target object (usually a QWidget or a QGraphicsObject) will
-    then need to update it's graphical representation to reflect the
-    new scroll position.
-
-    \section1 The Wheel Widget class
-
-    To demonstrate how to use the QScroller we implement a QWidget that
-    looks and works like the wheel of a slot machine.
-    The wheel can be started via touch events and will continue getting
-    slower.
-    Additionally the wheel should appear as if no border exists (which
-    would seem unnatural) and the scrolling should snap to center one
-    item.
-
-    In the widget we need to grab the QFlickGesture. The gesture itself
-    will setAcceptTouchEvents for us, so we don't need to do that here.
-
-    \snippet examples/scroller/wheel/wheelwidget.cpp 0
-
-    The widget will get gesture events but in addition we also will
-    get the events from QScroller.
-    We will need to accept the QScrollPrepareEvent to indicate that
-    a scrolling should really be started from the given position.
-
-    \snippet examples/scroller/wheel/wheelwidget.cpp 1
-
-    We should call all three set functions form QScrollPrepareEvent.
-
-    \list
-    \o \c setViewportSize to indicate our viewport size. Actually the
-     given code could be improved by giving our size minus the borders.
-    \o \c setMaxContentPos to indicate the maximum values for the scroll
-     position. The minimum values are implicitely set to 0.
-     In our example we give a very high number here and hope that the user
-     is not patient enough to scroll until the very end.
-    \o \c setContentPos to indicate the current scroll position.
-     We give a position in the middle of the huge scroll area.
-     Actually we give this position every time a new scroll is started so
-     the user will only reach the end if he continuously scrolls in one
-     direction which is not very likely.
-    \endlist
-
-    The handling of the QScrollEvent is a lengthly code not fully shown here.
-    \snippet examples/scroller/wheel/wheelwidget.cpp 2
-
-    In principle it does three steps.
-    \list
-    \o It calculates and updates the current scroll position as given by
-     QScroller.
-    \o It repaints the widget so that the new position is shown.
-    \o It centers the item as soon as the scrolling stopps.
-    \endlist
-
-    The following code does the centering.
-    \snippet examples/scroller/wheel/wheelwidget.cpp 3
-
-    We check if the scrolling is finished which is indicated in the
-    QScrollEvent by the \c isLast flag.
-    We then check if the item is not already centered and if not start a new
-    scroll by calling QScroller::scrollTo.
-
-    As you can see the QScroller can be used for other things besides simple
-    scroll areas.
