\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.
