SYNOPSIS

#include <Inventor/sensors/SoNodeSensor.h>

Methods from class SoNodeSensor:

SoNodeSensor()

SoNodeSensor(SoSensorCB *func, void *data)

~SoNodeSensor()

void attach(SoNode *node)

void detach()

SoNode * getAttachedNode() const

Methods from class SoDataSensor:

void setDeleteCallback(SoSensorCB *function, void *data)

SoNode * getTriggerNode() const

uint32_t getPriority()

static uint32_t getDefaultPriority()

virtual void schedule()

virtual void unschedule()

virtual SbBool isScheduled()

Methods from class SoSensor:

SoSensorCB * getFunction() const

void setData(void *callbackData)

void * getData() const

DESCRIPTION

Node sensors detect changes to nodes, calling a callback function whenever any field of the node or, if the node is a group node, any children of the node change.

METHODS

SoNodeSensor()

SoNodeSensor(SoSensorCB *func, void *data)

Creation methods. The second method takes the callback function and data to be called when the sensor is triggered.

~SoNodeSensor()

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

void attach(SoNode *node)

void detach()

SoNode * getAttachedNode() const

The attach() method makes this sensor detect changes to the given node. The detach() method unschedules this sensor (if it is scheduled) and makes it ignore changes to the scene graph. The getAttachedNode() method returns the node that this sensor is sensing, or NULL if it is not attached to any node.
