Detailed Description

Timer events are sent at regular intervals to objects that have started one or more timers. Each timer has a unique identifier.

If interval is 0, then the timer event occurs once every time there are no more window system events to process.

The QTimer class provides a high-level programming interface with one-shot timers and timer signals instead of events.

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

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