SoFieldSensor — sensor class that can be attached to Inventor fields

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

                         ~SoFieldSensor()
          Destroys the sensor, freeing up any memory associated with it after unscheduling it.

     voidattach(SoField*field)voiddetach()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.
