SoSensor(3IV)

NAME
     SoSensor (SoSens) - abstract base class for Inventor sensors

INHERITS FROM
     SoSensor

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

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

          Functions from class SoSensor:

     void                SoSensSetFunc(SoSens *this, SoSensorCB
                              *callbackFunction)
     SoSensorCB *        SoSensGetFunc(const SoSens *this)
     void                SoSensSetData(SoSens *this, void *callbackData)
     void *              SoSensGetData(const SoSens *this)


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.

FUNCTIONS
     void                SoSensSetFunc(SoSens *this, 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 *        SoSensGetFunc(const SoSens *this)
          Returns the callback function that will be called when the sensor is
          triggered.

     void                SoSensSetData(SoSens *this, void *callbackData)
          Sets the callback data passed to the callback function.

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