triggerEvent — trigger an already scheduled alarm.
void triggerEvent(const QString&
triggerEvent() is a D-Bus call to trigger
the immediate display or execution of the specified alarm (regardless
of what time it is scheduled for). KAlarm retrieves the alarm from
the calendar and then displays or executes it.
If the alarm is already due, KAlarm then deletes all scheduled occurrences of the alarm up to the current time, and if no repetitions of the alarm still remain, the alarm is deleted from the calendar. If the alarm is not due yet, its scheduled occurrences are left unchanged.
