◆ timerEvent()

void QTestEventLoop::timerEvent ( QTimerEvent event)

This event handler can be reimplemented in a subclass to receive timer events for the object.

QTimer provides a higher-level interface to the timer functionality, and also more general information about timers. The timer event is passed in the event parameter.

startTimer(), killTimer(), event()

Reimplemented from QObject.
