Overview

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.
