-    \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.

-    \class QScroller
-    \brief The QScroller class enables kinetic scrolling for any scrolling widget or graphics item.
-    \since 4.8
-
-    With kinetic scrolling, the user can push the widget in a given
-    direction and it will continue to scroll in this direction until it is
-    stopped either by the user or by friction.  Aspects of inertia, friction
-    and other physical concepts can be changed in order to fine-tune an
-    intuitive user experience.
-
-    The QScroller object is the object that stores the current position and
-    scrolling speed and takes care of updates.
-    QScroller can be triggered by a flick gesture
-
-    \code
-        QWidget *w = ...;
-        QScroller::grabGesture(w, QScroller::LeftMouseButtonGesture);
-    \endcode
-
-    or directly like this:
-
-    \code
-        QWidget *w = ...;
-        QScroller *scroller = QScroller::scroller(w);
-        scroller->scrollTo(QPointF(100, 100));
-    \endcode
-
-    The scrolled QObjects receive a QScrollPrepareEvent whenever the scroller needs to
-    update its geometry information and a QScrollEvent whenever the content of the object should
-    actually be scrolled.
-
-    The scroller uses the global QAbstractAnimation timer to generate its QScrollEvents. This
-    can be changed with QScrollerProperties::FrameRate on a per-QScroller basis.
-
-    Several examples in the \c scroller examples directory show how QScroller,
-    QScrollEvent and the scroller gesture can be used.
-
-    Even though this kinetic scroller has a large number of settings available via
-    QScrollerProperties, we recommend that you leave them all at their default, platform optimized
-    values. Before changing them you can experiment with the \c plot example in
-    the \c scroller examples directory.

-*/
-
-/*!
-    \enum QScrollerProperties::ScrollMetric
-
-    This enum contains the different scroll metric types. When not indicated otherwise the
-    setScrollMetric function expects a QVariant of type qreal.
-
-    See the QScroller documentation for further details of the concepts behind the different
-    values.
-
-    \value MousePressEventDelay This is the time a mouse press event is delayed when starting
-    a flick gesture in \c{[s]}. If the gesture is triggered within that time, no mouse press or
-    release is sent to the scrolled object. If it triggers after that delay the delayed
-    mouse press plus a faked release event at global postion \c{QPoint(-QWIDGETSIZE_MAX,
-    -QWIDGETSIZE_MAX)} is sent. If the gesture is canceled, then both the delayed mouse
-    press plus the real release event are delivered.
-
-    \value DragStartDistance This is the minimum distance the touch or mouse point needs to be
-    moved before the flick gesture is triggered in \c m.
-
-    \value DragVelocitySmoothingFactor A value that describes to which extent new drag velocities are
-    included in the final scrolling velocity.  This value should be in the range between \c 0 and
-    \c 1.  The lower the value, the more smoothing is applied to the dragging velocity.
-
-    \value AxisLockThreshold Restricts the movement to one axis if the movement is inside an angle
-    around the axis. The threshold must be in the range \c 0 to \c 1.
-
-    \value ScrollingCurve The QEasingCurve used when decelerating the scrolling velocity after an
-    user initiated flick. Please note that this is the easing curve for the positions, \bold{not}
-    the velocity: the default is QEasingCurve::OutQuad, which results in a linear decrease in
-    velocity (1st derivative) and a constant deceleration (2nd derivative).
-
-    \value DecelerationFactor This factor influences how long it takes the scroller to decelerate
-    to 0 velocity. The actual value depends on the chosen ScrollingCurve. For most
-    types the value should be in the range from \c 0.1 to \c 2.0
-
-    \value MinimumVelocity The minimum velocity that is needed after ending the touch or releasing
-    the mouse to start scrolling in \c{m/s}.
-
-    \value MaximumVelocity This is the maximum velocity that can be reached in \c{m/s}.
-
-    \value MaximumClickThroughVelocity This is the maximum allowed scroll speed for a click-through
-    in \c{m/s}. This means that a click on a currently (slowly) scrolling object will not only stop
-    the scrolling but the click event will also be delivered to the UI control. This is
-    useful when using exponential-type scrolling curves.
-
-    \value AcceleratingFlickMaximumTime This is the maximum time in \c seconds that a flick gesture
-    can take to be recognized as an accelerating flick. If set to zero no such gesture is
-    detected. An "accelerating flick" is a flick gesture executed on an already scrolling object.
-    In such cases the scrolling speed is multiplied by AcceleratingFlickSpeedupFactor in order to
-    accelerate it.
-
-    \value AcceleratingFlickSpeedupFactor The current speed is multiplied by this number if an
-    accelerating flick is detected. Should be \c{>= 1}.
-
-    \value SnapPositionRatio This is the distance that the user must drag the area beween two snap
-    points in order to snap it to the next position. \c{0.33} means that the scroll must only
-    reach one third of the distance between two snap points to snap to the next one. The ratio must
-    be between \c 0 and \c 1.
-
-    \value SnapTime This is the time factor for the scrolling curve. A lower value means that the
-    scrolling will take longer. The scrolling distance is independet of this value.
-
-    \value OvershootDragResistanceFactor This value is the factor between the mouse dragging and
-    the actual scroll area movement (during overshoot). The factor must be between \c 0 and \c 1.
-
-    \value OvershootDragDistanceFactor This is the maximum distance for overshoot movements while
-    dragging. The actual overshoot distance is calculated by multiplying this value with the
-    viewport size of the scrolled object. The factor must be between \c 0 and \c 1.
-
-    \value OvershootScrollDistanceFactor This is the maximum distance for overshoot movements while
-    scrolling. The actual overshoot distance is calculated by multiplying this value with the
-    viewport size of the scrolled object. The factor must be between \c 0 and \c 1.
-
-    \value OvershootScrollTime This is the time in \c seconds that is used to play the
-    complete overshoot animation.
-
-    \value HorizontalOvershootPolicy This is the horizontal overshooting policy (see OvershootPolicy).
-
-    \value VerticalOvershootPolicy This is the horizontal overshooting policy (see OvershootPolicy).
-
-    \value FrameRate This is the frame rate which should be used while dragging or scrolling.
-    QScroller uses a QAbstractAnimation timer internally to sync all scrolling operations to other
-    animations that might be active at the same time.  If the standard value of 60 frames per
-    second is too fast, it can be lowered with this setting,
-    while still being in-sync with QAbstractAnimation. Please note that only the values of the
-    FrameRates enum are allowed here.
-
-    \value ScrollMetricCount This is always the last entry.
