By inheriting this class, you can create custom + animations that plug into the rest of the animation framework. + + The progress of an animation is given by its current time + (currentLoopTime()), which is measured in milliseconds from the start + of the animation (0) to its end (duration()). The value is updated + automatically while the animation is running. It can also be set + directly with setCurrentTime(). + + At any point an animation is in one of three states: + \l{QAbstractAnimation::}{Running}, + \l{QAbstractAnimation::}{Stopped}, or + \l{QAbstractAnimation::}{Paused}--as defined by the + \l{QAbstractAnimation::}{State} enum. The current state can be + changed by calling start(), stop(), pause(), or resume(). An + animation will always reset its \l{currentTime()}{current time} + when it is started. If paused, it will continue with the same + current time when resumed. When an animation is stopped, it cannot + be resumed, but will keep its current time (until started again). + QAbstractAnimation will emit stateChanged() whenever its state + changes. + + An animation can loop any number of times by setting the loopCount + property. When an animation's current time reaches its duration(), + it will reset the current time and keep running. A loop count of 1 + (the default value) means that the animation will run one time. + Note that a duration of -1 means that the animation will run until + stopped; the current time will increase indefinitely. When the + current time equals duration() and the animation is in its + final loop, the \l{QAbstractAnimation::}{Stopped} state is + entered, and the finished() signal is emitted. + + QAbstractAnimation provides pure virtual functions used by + subclasses to track the progress of the animation: duration() and + updateCurrentTime(). The duration() function lets you report a + duration for the animation (as discussed above). The animation + framework calls updateCurrentTime() when current time has changed. + By reimplementing this function, you can track the animation + progress. Note that neither the interval between calls nor the + number of calls to this function are defined; though, it will + normally be 60 updates per second. + + By reimplementing updateState(), you can track the animation's + state changes, which is particularly useful for animations that + are not driven by time. + + \sa QVariantAnimation, QPropertyAnimation, QAnimationGroup, {The Animation Framework} +*/ + +/*! + \enum QAbstractAnimation::DeletionPolicy + + \value KeepWhenStopped The animation will not be deleted when stopped. + \value DeleteWhenStopped The animation will be automatically deleted when + stopped. +*/ + +/*! + \fn QAbstractAnimation::finished() + + QAbstractAnimation emits this signal after the animation has stopped and + has reached the end. + + This signal is emitted after stateChanged(). + + \sa stateChanged() +*/ + +/*! + \fn QAbstractAnimation::stateChanged(QAbstractAnimation::State newState, QAbstractAnimation::State oldState) + + QAbstractAnimation emits this signal whenever the state of the animation has + changed from \a oldState to \a newState.

A group is usually responsible for managing + the \l{QAbstractAnimation::State}{state} of its animations, i.e., + it decides when to start, stop, resume, and pause them. Currently, + Qt provides two such groups: QParallelAnimationGroup and + QSequentialAnimationGroup. Look up their class descriptions for + details. + + Since QAnimationGroup inherits from QAbstractAnimation, you can + combine groups, and easily construct complex animation graphs. + You can query QAbstractAnimation for the group it belongs to + (using the \l{QAbstractAnimation::}{group()} function). + + To start a top-level animation group, you simply use the + \l{QAbstractAnimation::}{start()} function from + QAbstractAnimation. By a top-level animation group, we think of a + group that itself is not contained within another group. Starting + sub groups directly is not supported, and may lead to unexpected + behavior. + + \omit OK, we'll put in a snippet on this here \endomit + + QAnimationGroup provides methods for adding and retrieving + animations. Besides that, you can remove animations by calling + remove(), and clear the animation group by calling + clear(). You may keep track of changes in the group's + animations by listening to QEvent::ChildAdded and + QEvent::ChildRemoved events. + + \omit OK, let's find a snippet here as well. \endomit + + QAnimationGroup takes ownership of the animations it manages, and + ensures that they are deleted when the animation group is deleted. + + \sa QAbstractAnimation, QVariantAnimation, {The Animation Framework} +*/ + +#include "qanimationgroup.h" +#include <QtCore/qdebug.h> +#include <QtCore/qcoreevent.h> +#include "qanimationgroup_p.h" + +#ifndef QT_NO_ANIMATION + +QT_BEGIN_NAMESPACE + + +/*! + Constructs a QAnimationGroup. + \a parent is passed to QObject's constructor. +*/ +QAnimationGroup::QAnimationGroup(QObject *parent) + : QAbstractAnimation(*new QAnimationGroupPrivate, parent) +{ +} + +/*! + \internal +*/ +QAnimationGroup::QAnimationGroup(QAnimationGroupPrivate &dd, QObject *parent) + : QAbstractAnimation(dd, parent) +{ +} + +/*! + Destroys the animation group.

It serves as a + base class for property and item animations, with functions for + shared functionality. + + QVariantAnimation cannot be used directly as it is an abstract + class; it has a pure virtual method called updateCurrentValue(). + The class performs interpolation over + \l{QVariant}s, but leaves using the interpolated values to its + subclasses. Currently, Qt provides QPropertyAnimation, which + animates Qt \l{Qt's Property System}{properties}. See the + QPropertyAnimation class description if you wish to animate such + properties. + + You can then set start and end values for the property by calling + setStartValue() and setEndValue(), and finally call start() to + start the animation. QVariantAnimation will interpolate the + property of the target object and emit valueChanged(). To react to + a change in the current value you have to reimplement the + updateCurrentValue() virtual function. + + It is also possible to set values at specified steps situated + between the start and end value. The interpolation will then + touch these points at the specified steps. Note that the start and + end values are defined as the key values at 0.0 and 1.0. + + There are two ways to affect how QVariantAnimation interpolates + the values. You can set an easing curve by calling + setEasingCurve(), and configure the duration by calling + setDuration(). You can change how the QVariants are interpolated + by creating a subclass of QVariantAnimation, and reimplementing + the virtual interpolated() function. + + Subclassing QVariantAnimation can be an alternative if you have + \l{QVariant}s that you do not wish to declare as Qt properties. + Note, however, that you in most cases will be better off declaring + your QVariant as a property. + + Not all QVariant types are supported. Below is a list of currently + supported QVariant types: + + \list + \o \l{QMetaType::}{Int} + \o \l{QMetaType::}{Double} + \o \l{QMetaType::}{Float} + \o \l{QMetaType::}{QLine} + \o \l{QMetaType::}{QLineF} + \o \l{QMetaType::}{QPoint} + \o \l{QMetaType::}{QPointF} + \o \l{QMetaType::}{QSize} + \o \l{QMetaType::}{QSizeF} + \o \l{QMetaType::}{QRect} + \o \l{QMetaType::}{QRectF} + \o \l{QMetaType::}{QColor} + \endlist + + If you need to interpolate other variant types, including custom + types, you have to implement interpolation for these yourself. + To do this, you can register an interpolator function for a given + type. This function takes 3 parameters: the start value, the end value + and the current progress. + + Example: + \code + QVariant myColorInterpolator(const QColor &start, const QColor &end, qreal progress) + { + ... + return QColor(...); + } + ... + qRegisterAnimationInterpolator<QColor>(myColorInterpolator); + \endcode + + Another option is to reimplement interpolated(), which returns + interpolation values for the value being interpolated. + + \omit We need some snippets around here. \endomit + + \sa QPropertyAnimation, QAbstractAnimation, {The Animation Framework} +*/ + +/*! + \fn void QVariantAnimation::valueChanged(const QVariant &value) + + QVariantAnimation emits this signal whenever the current \a value changes. + + \sa currentValue, startValue, endValue +*/ + +/*! + \fn void QVariantAnimation::updateCurrentValue(const QVariant &value) = 0; + + This pure virtual function is called every time the animation's current + value changes.
