| \class QPauseAnimation |
| \inmodule QtCore |
| \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. |
| |
