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.
