SoSensor(3IV)

NAME
     SoSensor - abstract base class for Inventor sensors

INHERITS FROM
     SoSensor

SYNOPSIS
     #include <Inventor/sensors/SoSensor.h>

     typedef void        SoSensorCB(void *data, SoSensor *sensor)

          Methods from class SoSensor:

     void                setFunction(SoSensorCB *callbackFunction)
     SoSensorCB *        getFunction() const
     void                setData(void *callbackData)
     void *              getData() const


DESCRIPTION
     Sensors detect changes either to time or to Inventor objects in a scene
     graph, and call a user-defined callback function. Sensors are scheduled
     when the thing they are attached to changes, and sometime after they are
     scheduled they are triggered, calling the user's callback function.

METHODS
     void                setFunction(SoSensorCB *callbackFunction)
          Sets the callback function that is called when the sensor is
          triggered. The function must take two arguments - user-supplied
          callback data (of type void *) and a pointer to the sensor that is
          triggering the function (of type SoSensor *).

     SoSensorCB *        getFunction() const
          Returns the callback function that will be called when the sensor is
          triggered.

     void                setData(void *callbackData)
          Sets the callback data passed to the callback function.

     void *              getData() const
          Returns the user-supplied pointer that will be passed to the
          callback function.
