319 | A small example on how to use AlarmServer. | ||
320 | |||
321 | First we need to connect a slot the AppMessage QCOP call. appMessage | ||
322 | will be emitted if QPE/Application/appname gets called. | ||
323 | |||
324 | \code | ||
325 | TestApp::TestApp(QWidget *parent, const char* name, WFlags fl ) | ||
326 | : QMainWindow(parent,name,fl){ | ||
327 | connect(qApp,SIGNAL(appMessage(const QCString&,const QByteArray&)), | ||
328 | this,SLOT(slotAppMessage(const QCString&,const QByteArray&))); | ||
329 | } | ||
330 | \endcode | ||
331 | |||
332 | To add / delete an alarm, you can use the static method AlarmServer::addAlarm and | ||
333 | AlarmServer::deleteAlarm. Note that an old (expired) alarm will automatically be deleted | ||
334 | from the alarmserver list, but a change in timing will have the effect, that both | ||
335 | alarms will be emitted. So if you change an Alarm be sure to delete the old one! | ||
336 | @see addAlarm | ||
337 | |||
338 | \code | ||
339 | QDateTime oldDt = oldAlarmDateTime(); | ||
340 | QPEApplication::execDialog(ourDlg); | ||
341 | QDateTime newDt = ourDlg->dateTime(); | ||
342 | if(newDt == oldDt ) return; | ||
343 | @slash* code is missing for unsetting an alarm *@slash | ||
344 | |||
345 | AlarmServer::deleteAlarm(oldDt,"QPE/Application/appname","checkAlarm(QDateTime,int)",0); | ||
346 | AlarmServer::addAlarm( newDt,"QPE/AlarmServer/appname","checkAlarm(QDateTime,int)",0); | ||
347 | |||
348 | \endcode | ||
349 | |||
350 | Now once the Alarm is emitted you need to check the appMessage and then do what you want. | ||
351 | \code | ||
352 | void TestApp::slotAppMessage(const QCString& str, const QByteArray& ar ){ | ||
353 | QDataStream stream(ar,IO_ReadOnly); | ||
354 | if(str == "checkAlarm(QDateTime,int)" ){ | ||
355 | QDateTime dt; | ||
356 | int a; | ||
357 | stream >> dt >> a; | ||
358 | // fire up alarm | ||
359 | } | ||
360 | } | ||
