Detailed Description

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 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 addPause() and insertPause(). These functions simply take the number of milliseconds the pause should last.

See also QSequentialAnimationGroup.

Member Function Documentation

QPauseAnimation::QPauseAnimation(int msecs, QObject *parent = nullptr)

Constructs a QPauseAnimation. msecs is the duration of the pause. parent is passed to QObject's constructor.

QPauseAnimation::QPauseAnimation(QObject *parent = nullptr)

Constructs a QPauseAnimation. parent is passed to QObject's constructor. The default duration is 0.

[virtual] QPauseAnimation::~QPauseAnimation()

Destroys the pause animation.

[override virtual protected] bool QPauseAnimation::event(QEvent *e)

Reimplements: QAbstractAnimation::event(QEvent *event).

[override virtual protected] void QPauseAnimation::updateCurrentTime(int)

Reimplements: QAbstractAnimation::updateCurrentTime(int currentTime).
