Detailed Description

Sensor class that can be attached to Open Inventor paths.

Path sensors detect changes to paths, calling a callback function whenever the path or any node in the path changes.

The definition of "in the path" is the same as the definition used when applying an action to the path - any node that can possibly affect the node at the end of the path chain is considered in the path. See the SoPath manual page for more information on paths.

See SoDataSensor for general information and code example.

Constructor & Destructor Documentation

SoPathSensor::SoPathSensor (  ) 

Default constructor.

SoPathSensor::SoPathSensor ( SoSensorCB func,
void *  data 

Constructor that takes the callback function and data to be called when the sensor is triggered.

virtual SoPathSensor::~SoPathSensor (  )  [virtual]

Destroys the sensor, freeing up any memory associated with it after unscheduling it.

Member Function Documentation

void SoPathSensor::attach ( SoPath path  ) 

Makes this sensor detect changes to the given path.

void SoPathSensor::detach (  ) 

Unschedules this sensor (if it is scheduled) and makes it ignore changes to the scene graph.

SoPath* SoPathSensor::getAttachedPath (  )  const [inline]

Returns the path that this sensor is sensing, or NULL if it is not attached to any path.
