    \class QPauseAnimation
    \brief The QPauseAnimation class provides a pause for QSequentialAnimationGroup.
    \since 4.6
    \ingroup animation

    If you wish to introduce a delay between animations in a
    QSequentialAnimationGroup, you can insert a QPauseAnimation. This
    class does not animate anything, but does not
    \l{QAbstractAnimation::finished()}{finish} before a specified
    number of milliseconds have elapsed from when it was started. You
    specify the duration of the pause in the constructor. It can also
    be set directly with setDuration().

    It is not necessary to construct a QPauseAnimation yourself.
    QSequentialAnimationGroup provides the convenience functions
    \l{QSequentialAnimationGroup::}{addPause()} and
    \l{QSequentialAnimationGroup::}{insertPause()}. These functions
    simply take the number of milliseconds the pause should last.

    \sa QSequentialAnimationGroup
