Constructor & Destructor Documentation

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 the callback. See also: setFunction(), setData()

SoFieldSensor::~SoFieldSensor (  void )  [virtual]

Destructor.

Member Function Documentation

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. See also: detach()

void SoFieldSensor::detach (  void )

Detach sensor from field. As long as an SoFieldSensor is detached, it will never call its callback function. See also: attach()

SoField * SoFieldSensor::getAttachedField (  void )  const

Returns a pointer to the field connected to the sensor. See also: attach(), detach()

void SoFieldSensor::trigger (  void )  [virtual]

Overloaded to clear scheduled flag before triggering. Reimplemented from SoDataSensor.
