Detailed Description

The SoNodeSensor class detects changes to nodes.

Attach a node to a sensor of this type to put it under surveillance, so you can act upon changes to the node.

Any modification to the node's fields will trigger the sensor, as will changes to node's children (if any), including if nodes are added or removed as children below the node in the subgraph.

An SoNodeSensor can also act for delete-callback purposes alone and does not need a regular notification-based callback.

Constructor & Destructor Documentation

◆ SoNodeSensor() [1/2]

SoNodeSensor::SoNodeSensor ( void )

Default constructor.

◆ SoNodeSensor() [2/2]

SoNodeSensor::SoNodeSensor	(	SoSensorCB *	func,
		void *	data
	)

Constructor taking as parameters the sensor callback function and the userdata which will be passed the callback.

See also: setFunction(), setData()

◆ ~SoNodeSensor()

SoNodeSensor::~SoNodeSensor ( void )

virtual

Destructor.

Member Function Documentation

◆ attach()

void SoNodeSensor::attach ( SoNode * node )

Attach sensor to a node. Whenever any data in the node (or its children, if it's an SoGroup or SoGroup derived node) changes, the sensor will be triggered and call the callback function.

Attaching a node sensor to a node will not increase the node's reference count (and conversely, detach()'ing the node sensor will not decrease the reference count, either).

When the attached node is deleted, the sensor will be automatically detached().

See also: detach()

◆ detach()

void SoNodeSensor::detach ( void )

Detach sensor from node. As long as an SoNodeSensor is detached, it will never call its callback function.

See also: attach()

◆ getAttachedNode()

SoNode * SoNodeSensor::getAttachedNode ( void ) const

Returns a pointer to the node connected to the sensor.

See also: attach(), detach()
