41 \class QPauseAnimation
42 \inmodule QtCore
43 \brief The QPauseAnimation class provides a pause for QSequentialAnimationGroup.
44 \since 4.6
45 \ingroup animation
46
47 If you wish to introduce a delay between animations in a
48 QSequentialAnimationGroup, you can insert a QPauseAnimation. This
49 class does not animate anything, but does not
50 \l{QAbstractAnimation::finished()}{finish} before a specified
51 number of milliseconds have elapsed from when it was started. You
52 specify the duration of the pause in the constructor. It can also
53 be set directly with setDuration().
54
55 It is not necessary to construct a QPauseAnimation yourself.
56 QSequentialAnimationGroup provides the convenience functions
57 \l{QSequentialAnimationGroup::}{addPause()} and
58 \l{QSequentialAnimationGroup::}{insertPause()}. These functions
59 simply take the number of milliseconds the pause should last.
