46 | Description:
47 | Data sensor that is attached to a node in a scene graph. The
48 | sensor is scheduled when a change is made to the node or to any
49 | node below it in the graph.

void SoSensorCB(void *data, SoSensor *sensor)
This typedef defines the calling sequence for all callbacks from sensors.
Definition SoSensor.h:89
Abstract base class for sensors attached to parts of a scene.
virtual void dyingReference()=0
This is called when the base (path, field, node, whatever) is deleted.
Sensor class that can be attached to Inventor nodes.
void detach()
Unschedules this sensor (if it is scheduled) and makes it ignore changes to the scene graph.
SoNode * getAttachedNode() const
Returns the node that this sensor is sensing, or NULL if it is not attached to any node.
virtual ~SoNodeSensor()
Destroys the sensor, freeing up any memory associated with it after unscheduling it.
SoNodeSensor()
Creation methods.
void attach(SoNode *node)
Makes this sensor detect changes to the given node.
SoNodeSensor(SoSensorCB *func, void *data)
Creation methods.
Abstract base class for all database nodes.
