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.
