void SoSensorCB(void *data, SoSensor *sensor)
This typedef defines the calling sequence for all callbacks from sensors.
Definition SoSensor.h:65
Class for representation of a time.
Definition SbTime.h:91
Abstract base class for Open Inventor sensors.
Definition SoSensor.h:97
Abstract base class for sensors dependent on time.
SoTimerQueueSensor(SoSensorCB *func, void *data)
Constructor that takes standard callback function and data.
virtual void schedule()
Adds this sensor to the timer queue.
const SbTime & getTriggerTime() const
Returns the time at which this sensor is scheduled to be triggered.
SoTimerQueueSensor()
Constructor.
virtual void unschedule()
