       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.
