Member Function Documentation

  void SoAlarmSensor::setTime (const SbTime & abstime)
Set the time at which the sensor will trigger.

Note that you must manually schedule() the sensor after calling this method.

    setTimeFromNow(), getTime()

  void SoAlarmSensor::setTimeFromNow (const SbTime & reltime)
Set the alarm to be at a specified offset from the current time.

Note that you must manually schedule() the sensor after calling this method.

See also:
    setTime(), getTime()

  const SbTime & SoAlarmSensor::getTime (void) const
Returns the trigger time for the alarm as an absolute value from 1970-01-01 00:00:00.

See also:
    setTime(), setTimeFromNow()

  void SoAlarmSensor::schedule (void) [virtual]
Put the sensor in the global timer queue.
