qcron is a cron-like scheduler based on Qt. Using a pattern following cron syntax, a QCron object will emit signals when the system time (given by QDateTime) enters a valid time table or when it leaves such time table.
/* From monday to friday, every minutes from 8:00 to 11:59 and from
14:00 to 17:59. */
QCron cron("* 8-11,14-17 * * 1-5 *");
connect(&cron, SIGNAL(activated()), this, SLOT(onActivation()));
connect(&cron, SIGNAL(deactivated()), this, SLOT(onDeactivation()));The 'activated' signal will be emitted every weekday at 8.00 and 14.00, and the 'deactivated' signal will be emitted every weekday at 12.00 and 18.00.
