## Detailed Description

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 QTimer 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.

See also QTimer, QObject::timerEvent(), QObject::startTimer(), and QObject::killTimer().
