In the "moved state, the rectangle's position changes - to (50, 50). The added Transition specifies that when the rectangle - changes between the default and the "moved" state, any changes - to the \c x and \c y properties should be animated, using an \c Easing.InOutQuad. - - \snippet doc/src/snippets/qtquick1/transition.qml 0 - - Notice the example does not require \l{PropertyAnimation::}{to} and - \l{PropertyAnimation::}{from} values for the NumberAnimation. As a convenience, - these properties are automatically set to the values of \c x and \c y before - and after the state change; the \c from values are provided by - the current values of \c x and \c y, and the \c to values are provided by - the PropertyChanges object. If you wish, you can provide \l{PropertyAnimation::}{to} and - \l{PropertyAnimation::}{from} values anyway to override the default values. - - By default, a Transition's animations are applied for any state change in the - parent item. The Transition \l {Transition::}{from} and \l {Transition::}{to} - values can be set to restrict the animations to only be applied when changing - from one particular state to another. - - To define multiple transitions, specify \l Item::transitions as a list: - - \snippet doc/src/snippets/qtquick1/transitions-list.qml list of transitions - - If multiple Transitions are specified, only a single (best-matching) Transition will be applied for any particular - state change. In the example above, when changing to \c state1, the first transition will be used, rather - than the more generic second transition. - - If a state change has a Transition that matches the same property as a - \l Behavior, the Transition animation overrides the \l Behavior for that - state change. - - \sa {QML Animation and Transitions}, {declarative/animation/states}{states example}, {qmlstates}{States}, {QtDeclarative} -*/ - -//ParallelAnimationWrapper_1 allows us to do a "callback" when the animation finishes, rather than connecting -//and disconnecting signals and slots frequently -class ParallelAnimationWrapper_1 : public QParallelAnimationGroup -{ - Q_OBJECT -public: - ParallelAnimationWrapper_1(QObject *parent = 0) : QParallelAnimationGroup(parent) {} - QDeclarative1TransitionPrivate *trans; -protected: - virtual void updateState(QAbstractAnimation::State newState, QAbstractAnimation::State oldState); -}; - -class QDeclarative1TransitionPrivate : public QObjectPrivate -{ - Q_DECLARE_PUBLIC(QDeclarative1Transition) -public: - QDeclarative1TransitionPrivate() - : fromState(QLatin1String("*")), toState(QLatin1String("*")), - reversed(false), reversible(false), endState(0) - { - group.trans = this; - } - - QString fromState; - QString toState; - bool reversed; - bool reversible; - ParallelAnimationWrapper_1 group; - QDeclarative1TransitionManager *endState; - - void complete() - { - endState->complete(); - } - static void append_animation(QDeclarativeListProperty<QDeclarative1AbstractAnimation> *list, QDeclarative1AbstractAnimation *a); - static int animation_count(QDeclarativeListProperty<QDeclarative1AbstractAnimation> *list); - static QDeclarative1AbstractAnimation* animation_at(QDeclarativeListProperty<QDeclarative1AbstractAnimation> *list, int pos); - static void clear_animations(QDeclarativeListProperty<QDeclarative1AbstractAnimation> *list); - QList<QDeclarative1AbstractAnimation *> animations; -}; - -void QDeclarative1TransitionPrivate::append_animation(QDeclarativeListProperty<QDeclarative1AbstractAnimation> *list, QDeclarative1AbstractAnimation *a) -{ - QDeclarative1Transition *q = static_cast<QDeclarative1Transition *>(list->object); - q->d_func()->animations.append(a); - q->d_func()->group.addAnimation(a->qtAnimation()); - a->setDisableUserControl(); -} - -int QDeclarative1TransitionPrivate::animation_count(QDeclarativeListProperty<QDeclarative1AbstractAnimation> *list) -{ - QDeclarative1Transition *q = static_cast<QDeclarative1Transition *>(list->object); - return q->d_func()->animations.count(); -} - -QDeclarative1AbstractAnimation* QDeclarative1TransitionPrivate::animation_at(QDeclarativeListProperty<QDeclarative1AbstractAnimation> *list, int pos) -{ - QDeclarative1Transition *q = static_cast<QDeclarative1Transition *>(list->object); - return q->d_func()->animations.at(pos); -} - -void QDeclarative1TransitionPrivate::clear_animations(QDeclarativeListProperty<QDeclarative1AbstractAnimation> *list) -{ - QDeclarative1Transition *q = static_cast<QDeclarative1Transition *>(list->object); - while (q->d_func()->animations.count()) { - QDeclarative1AbstractAnimation *firstAnim = q->d_func()->animations.at(0); - q->d_func()->group.removeAnimation(firstAnim->qtAnimation()); - q->d_func()->animations.removeAll(firstAnim); - } -} - -void ParallelAnimationWrapper_1::updateState(QAbstractAnimation::State newState, QAbstractAnimation::State oldState) -{ - QParallelAnimationGroup::updateState(newState, oldState); - if (newState == Stopped && (duration() == -1 - || (direction() == QAbstractAnimation::Forward && currentLoopTime() == duration()) - || (direction() == QAbstractAnimation::Backward && currentLoopTime() == 0))) - { - trans->complete(); - } -} - - - -QDeclarative1Transition::QDeclarative1Transition(QObject *parent) - : QObject(*(new QDeclarative1TransitionPrivate), parent) -{ -} - -QDeclarative1Transition::~QDeclarative1Transition() -{ -} - -void QDeclarative1Transition::stop() -{ - Q_D(QDeclarative1Transition); - d->group.stop(); -} - -void QDeclarative1Transition::setReversed(bool r) -{ - Q_D(QDeclarative1Transition); - d->reversed = r; -} - -void QDeclarative1Transition::prepare(QDeclarative1StateOperation::ActionList &actions, - QList<QDeclarativeProperty> &after, - QDeclarative1TransitionManager *endState) -{ - Q_D(QDeclarative1Transition); - - qmlExecuteDeferred(this); - - if (d->reversed) { - for (int ii = d->animations.count() - 1; ii >= 0; --ii) { - d->animations.at(ii)->transition(actions, after, QDeclarative1AbstractAnimation::Backward); - } - } else { - for (int ii = 0; ii < d->animations.count(); ++ii) { - d->animations.at(ii)->transition(actions, after, QDeclarative1AbstractAnimation::Forward); - } - } - - d->endState = endState; - d->group.setDirection(d->reversed ?
