Detailed Description

\inmodule QtCore

QUnifiedTimer provides a unified timing mechanism for animations in Qt C++ and QML.

QUnifiedTimer allows animations run by Qt to share a single timer. This keeps animations visually in sync, as well as being more efficient than running numerous timers.

QUnifiedTimer drives animations indirectly, via QAbstractAnimationTimer.

This event handler can be reimplemented in a subclass to receive timer events for the object.

QChronoTimer provides higher-level interfaces to the timer functionality, and also more general information about timers. The timer event is passed in the event parameter.
