cancelEvent — cancel an already scheduled alarm.
void cancelEvent(const QString&calendarFile, const QString&eventID)
cancelEvent() is a DCOP call to cancel
the specified alarm. KAlarm deletes the alarm from the calendar file
without displaying or executing it.
The calendarFile parameter is
only used for integrity checking: if the URL does not specify
KAlarm's current default calendar file, the request will be
ignored.
