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.

An SoFieldSensor can also act for delete-callback purposes alone and does not need a regular notification-based callback.

Constructor & Destructor Documentation

◆ SoFieldSensor() [1/2]

SoFieldSensor::SoFieldSensor ( void  )


◆ SoFieldSensor() [2/2]

SoFieldSensor::SoFieldSensor ( SoSensorCB func,
void *  data 

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

setFunction(), setData()

◆ ~SoFieldSensor()

SoFieldSensor::~SoFieldSensor ( void  )


Member Function Documentation

◆ attach()

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

◆ 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

◆ getAttachedField()

SoField * SoFieldSensor::getAttachedField ( void  ) const

Returns a pointer to the field connected to the sensor.

See also
attach(), detach()

◆ trigger()

void SoFieldSensor::trigger ( void  )

Trigger the sensor's callback function.
