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.
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.
SoFieldSensor::~SoFieldSensor | ( | void | ) | [virtual] |
Destructor.
References detach().
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.

void SoFieldSensor::detach | ( | void | ) |
Detach sensor from field. As long as an SoFieldSensor is detached, it will never call its callback function.
