- -/*! - \class GfxEasing - \ingroup group_animation - \brief The GfxEasing class provides easing curves for controlling animation. - - Easing curves describe a function that controls how a value changes over - time. Easing curves allow transitions from one value to another to appear - more natural than a simple linear motion would allow. The GfxEasing class - is usually used in conjunction with the GfxTimeLine class, but can be used - on its own. - - To calculate the value at a given time, the easing curve function requires - the starting value, the final value and the total time to change from the - starting to the final value. When using the GfxEasing class with - GfxTimeLine, these values are supplied by the GfxTimeLine. When using - the GfxEasing class on its own, the programmer must specify them using - the GfxEasing::setFrom(), GfxEasing::setTo() and GfxEasing::setLength() - methods, or by passing them explicitly to the GfxEasing::valueAt() method. - - For example, - \code - GfxEasing easing(GfxEasing::InOutQuad); - easing.setFrom(0); - easing.setTo(1000); - easing.setLength(1000); - - for(int milliseconds = 0; milliseconds < 1000; ++milliseconds) - qWarning() << "Value at" << milliseconds << "milliseconds is - << easing.valueAt(milliseconds); - \endcode - will print the value at each millisecond for an InOutQuad transition from - 0 to 1000 over 1 second. - - When using a GfxTimeLine, the values are communicated implicitly. - \code - GfxTimeLine timeline; - GfxValue value(0); - - timeline.move(value, 1000, GfxEasing(GfxEasing::InOutQuad), 1000); - \endcode - In this case, any values set using the previous setter methods would be - ignored. - */ - -/*! - \qmlproperty string NumericAnimation::easing - \brief the easing curve used for the transition. - - Available values are: - - \list - \i \e easeNone - Easing equation function for a simple linear tweening, with no easing. - \i \e easeInQuad - Easing equation function for a quadratic (t^2) easing in: accelerating from zero velocity. - \i \e easeOutQuad - Easing equation function for a quadratic (t^2) easing out: decelerating to zero velocity. - \i \e easeInOutQuad - Easing equation function for a quadratic (t^2) easing in/out: acceleration until halfway, then deceleration. - \i \e easeOutInQuad - Easing equation function for a quadratic (t^2) easing out/in: deceleration until halfway, then acceleration. - \i \e easeInCubic - Easing equation function for a cubic (t^3) easing in: accelerating from zero velocity. - \i \e easeOutCubic - Easing equation function for a cubic (t^3) easing out: decelerating from zero velocity. - \i \e easeInOutCubic - Easing equation function for a cubic (t^3) easing in/out: acceleration until halfway, then deceleration. - \i \e easeOutInCubic - Easing equation function for a cubic (t^3) easing out/in: deceleration until halfway, then acceleration. - \i \e easeInQuart - Easing equation function for a quartic (t^4) easing in: accelerating from zero velocity. - \i \e easeOutQuart - Easing equation function for a quartic (t^4) easing out: decelerating from zero velocity. - \i \e easeInOutQuart - Easing equation function for a quartic (t^4) easing in/out: acceleration until halfway, then deceleration. - \i \e easeOutInQuart - Easing equation function for a quartic (t^4) easing out/in: deceleration until halfway, then acceleration. - \i \e easeInQuint - Easing equation function for a quintic (t^5) easing in: accelerating from zero velocity. - \i \e easeOutQuint - Easing equation function for a quintic (t^5) easing out: decelerating from zero velocity. - \i \e easeInOutQuint - Easing equation function for a quintic (t^5) easing in/out: acceleration until halfway, then deceleration. - \i \e easeOutInQuint - Easing equation function for a quintic (t^5) easing out/in: deceleration until halfway, then acceleration. - \i \e easeInSine - Easing equation function for a sinusoidal (sin(t)) easing in: accelerating from zero velocity. - \i \e easeOutSine - Easing equation function for a sinusoidal (sin(t)) easing out: decelerating from zero velocity. - \i \e easeInOutSine - Easing equation function for a sinusoidal (sin(t)) easing in/out: acceleration until halfway, then deceleration. - \i \e easeOutInSine - Easing equation function for a sinusoidal (sin(t)) easing out/in: deceleration until halfway, then acceleration. - \i \e easeInExpo - Easing equation function for an exponential (2^t) easing in: accelerating from zero velocity. - \i \e easeOutExpo - Easing equation function for an exponential (2^t) easing out: decelerating from zero velocity. - \i \e easeInOutExpo - Easing equation function for an exponential (2^t) easing in/out: acceleration until halfway, then deceleration. - \i \e easeOutInExpo - Easing equation function for an exponential (2^t) easing out/in: deceleration until halfway, then acceleration. - \i \e easeInCirc - Easing equation function for a circular (sqrt(1-t^2)) easing in: accelerating from zero velocity. - \i \e easeOutCirc - Easing equation function for a circular (sqrt(1-t^2)) easing out: decelerating from zero velocity. - \i \e easeInOutCirc - Easing equation function for a circular (sqrt(1-t^2)) easing in/out: acceleration until halfway, then deceleration. - \i \e easeOutInCirc - Easing equation function for a circular (sqrt(1-t^2)) easing out/in: deceleration until halfway, then acceleration. - \i \e easeInElastic - Easing equation function for an elastic (exponentially decaying sine wave) easing in: accelerating from zero velocity.

- \class QmlTimeLine - \ingroup group_animation - \brief The QmlTimeLine class provides a timeline for controlling animations. - - QmlTimeLine is similar to QTimeLine except: - \list - \i It updates GfxValue instances directly, rather than maintaining a single - current value. - - For example, the following animates a simple value over 200 milliseconds: - \code - GfxValue v(); - QmlTimeLine tl; - tl.move(v, 100., 200); - tl.start() - \endcode - - If your program needs to know when values are changed, it can either - connect to the QmlTimeLine's updated() signal, or inherit from GfxValue - and reimplement the GfxValue::setValue() method. - - \i Supports multiple GfxValue, arbitrary start and end values and allows - animations to be strung together for more complex effects. - - For example, the following animation moves the x and y coordinates of - an object from wherever they are to the position (100, 100) in 50 - milliseconds and then further animates them to (100, 200) in 50 - milliseconds: - - \code - GfxValue x(); - GfxValue y(); - - QmlTimeLine tl; - tl.start(); - - tl.move(x, 100., 50); - tl.move(y, 100., 50); - tl.move(y, 200., 50); - \endcode - - \i All QmlTimeLine instances share a single, synchronized clock. - - Actions scheduled within the same event loop tick are scheduled - synchronously against each other, regardless of the wall time between the - scheduling. Synchronized scheduling applies both to within the same - QmlTimeLine and across separate QmlTimeLine's within the same process. - - \endlist - - Currently easing functions are not supported. -*/ - - -/*! - Construct a new QmlTimeLine with the specified \a parent. -*/ -QmlTimeLine::QmlTimeLine(QObject *parent) -: QAbstractAnimation(parent) -{ - d = new QmlTimeLinePrivate(this); -} - -/*! - Destroys the time line.
