- \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.

- \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::FrameRates
-
- This enum describes the available frame rates used while dragging or scrolling.
-
- \value Fps60 60 frames per second
- \value Fps30 30 frames per second
- \value Fps20 20 frames per second
- \value Standard the default value is 60 frames per second (which corresponds to QAbstractAnimation).
-*/
-
-/*!
- \enum QScrollerProperties::OvershootPolicy
-
- This enum describes the various modes of overshooting.
-
- \value OvershootWhenScrollable Overshooting is possible when the content is scrollable. This is the
- default.
-
- \value OvershootAlwaysOff Overshooting is never enabled, even when the content is scrollable.
-
- \value OvershootAlwaysOn Overshooting is always enabled, even when the content is not
- scrollable.
-*/
-
-/*!
- \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.
