SoFieldSensor::SoFieldSensor (void )

Constructor.

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

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

See also

SoFieldSensor::~SoFieldSensor (void ) [virtual]

Destructor.

void SoFieldSensor::attach (SoField * field)

Attach sensor to a field. Whenever the field's value changes, the sensor will be triggered and call the callback function.

A field sensor can be attached to only a single field at a time. When this method is invoked multiple times, each subsequent call will replace the field the sensor is monitoring with the new field.

When the given field is deleted, the sensor will automatically be detached.

See also

void SoFieldSensor::detach (void )

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

See also

SoField * SoFieldSensor::getAttachedField (void ) const

Returns a pointer to the field connected to the sensor.

See also

void SoFieldSensor::trigger (void ) [virtual]

Trigger the sensor's callback function.
