\class QPauseAnimation
\brief The QPauseAnimation class provides a pause for QSequentialAnimationGroup.
\since 4.5
\ingroup animation
\preliminary
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::}{insertPauseAt()}. These functions
simply take the number of milliseconds the pause should last.
