Applications can schedule alarms with addAlarm() and can unschedule alarms with deleteAlarm(). When the time for an alarm to go off is reached the specified \link qcop.html QCop\endlink message is sent on the specified channel (optionally with additional data). Scheduling an alarm using this class is important (rather just using a QTimer) since the machine may be asleep and needs to get woken up using the Linux kernel which implements this at the kernel level to minimize battery usage while asleep. + A small example on how to use AlarmServer. + + First we need to connect a slot the AppMessage QCOP call. appMessage + will be emitted if QPE/Application/appname gets called. + + \code + TestApp::TestApp(QWidget *parent, const char* name, WFlags fl ) + : QMainWindow(parent,name,fl){ + connect(qApp,SIGNAL(appMessage(const QCString&,const QByteArray&)), + this,SLOT(slotAppMessage(const QCString&,const QByteArray&))); + } + \endcode + + To add / delete an alarm, you can use the static method AlarmServer::addAlarm and + AlarmServer::deleteAlarm. Note that an old (expired) alarm will automatically be deleted + from the alarmserver list, but a change in timing will have the effect, that both + alarms will be emitted.
