Detailed Description

The SoFieldSensor class detects changes to a field.

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


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]
 

Trigger the sensor's callback function.
