Detailed Description

\inmodule QtCore

The QTimerEvent class contains parameters that describe a timer event.

Timer events are sent at regular intervals to objects that have started one or more timers. Each timer has a unique identifier. A timer is started with QObject::startTimer().

The QChronoTimer class provides a high-level programming interface that uses signals instead of events. It also provides single-shot timers.

The event handler QObject::timerEvent() receives timer events.
