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.

detach()

void SoFieldSensor::detach

(

void

)

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

attach()

SoField * SoFieldSensor::getAttachedField

(

void

)

const

Returns a pointer to the field connected to the sensor.

void SoFieldSensor::trigger

(

void

)

[virtual]

Trigger the sensor's callback function.
