          Methods from class SoSensor:

     void                setFunction(SoSensorCB *callbackFunction)
     SoSensorCB *        getFunction() const

     void *              getData() const


       Field  sensors  detect  changes  to fields, calling a callback function whenever the field
       changes. The field may be part of a node, an input of an engine, or a global field.


                         SoFieldSensor(SoSensorCB *func, void *data)
          Creation methods. The second method takes the callback function and data to  be  called
          when the sensor is triggered.

          Destroys the sensor, freeing up any memory associated with it after unscheduling it.

     void                attach(SoField *field)
     void                detach()
     SoField *           getAttachedField() const
          The  attach()  method makes this sensor detect changes to the given field. The detach()
          method unschedules this sensor (if it is scheduled) and makes it ignore changes to  the
          scene  graph.  The  getAttachedField()  method  returns  the  field that this sensor is
          sensing, or NULL if it is not attached to any field.
