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