QParallelAnimationGroup Class

QParallelAnimationGroup 类提供了一组并行动画。更多

Header： #include <QParallelAnimationGroup>
CMake.QParallelAnimationGroup 类 find_package(Qt6 REQUIRED COMPONENTS Core)
target_link_libraries(mytarget PRIVATE Qt6::Core)
qmake： QT += core
继承： QAnimationGroup

公共函数

QParallelAnimationGroup(QObject *parent = nullptr)
virtual ~QParallelAnimationGroup()

重新实现的公共函数

virtual int duration() const override

重新实现的保护函数

virtual bool event(QEvent *event) override
virtual void updateCurrentTime(int currentTime) override
virtual void updateDirection(QAbstractAnimation::Direction direction) override
virtual void updateState(QAbstractAnimation::State newState, QAbstractAnimation::State oldState) override

详细说明

QParallelAnimationGroup 是一个container for animations，当它自身started 时，它将启动所有动画，即并行运行所有动画。动画组在持续时间最长的动画结束时结束。

您可以像对待其他QAbstractAnimation 一样对待 QParallelAnimationGroup，例如暂停、恢复或将其添加到其他动画组中。

    QParallelAnimationGroup *group = new QParallelAnimationGroup;
    group->addAnimation(anim1);
    group->addAnimation(anim2);

    group->start();

在本例中，anim1 和anim2 是已经设置好的两个QPropertyAnimations。

另请参阅 QAnimationGroup,QPropertyAnimation, 以及动画框架。

成员函数文档

QParallelAnimationGroup::QParallelAnimationGroup(QObject *parent = nullptr)

构造一个 QParallelAnimationGroup。parent 传递给QObject 的构造函数。

[virtual noexcept] QParallelAnimationGroup::~QParallelAnimationGroup()

销毁动画组。同时也会销毁其所有动画。

[override virtual] int QParallelAnimationGroup::duration() const

重实现：QAbstractAnimation::duration() const.

[override virtual protected] bool QParallelAnimationGroup::event(QEvent *event)

重实现：QAnimationGroup::event(QEvent *event).

[override virtual protected] void QParallelAnimationGroup::updateCurrentTime(int currentTime)

重实现：QAbstractAnimation::updateCurrentTime(int currentTime)。

[override virtual protected] void QParallelAnimationGroup::updateDirection(QAbstractAnimation::Direction direction)

重实现：QAbstractAnimation::updateDirection(QAbstractAnimation::Direction direction）。

[override virtual protected] void QParallelAnimationGroup::updateState(QAbstractAnimation::State newState, QAbstractAnimation::State oldState)

重实现：QAbstractAnimation::updateState(QAbstractAnimation::State newState, QAbstractAnimation::State oldState）。
