.SH DESCRIPTION
The QTimerEvent class contains parameters that describe a timer event.
.PP
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().
.PP
The QTimer class provides a high-level programming interface that uses signals instead of events. It also provides one-shot timers.
.PP
The event handler QObject::timerEvent() receives timer events.
.PP
See also QTimer, QObject::timerEvent(), QObject::startTimer(), QObject::killTimer() and QObject::killTimers().
