Abstract base class for sensors not dependent on time.
SoDelayQueueSensor()
Constructor.
virtual void schedule()
If this sensor's priority is non-zero, adds this sensor to the list of delay queue sensors ready to b...
uint32_t getPriority() const
Gets the priority of the sensor.
static uint32_t getDefaultPriority()
Returns the default delay queue sensor priority, which is 100.
virtual SbBool isIdleOnly() const
void setPriority(uint32_t pri)
Sets the priority of the sensor.
virtual void unschedule()
If this sensor is scheduled, removes it from the delay queue so that it will not be triggered.
SoDelayQueueSensor(SoSensorCB *func, void *data)
Constructor that takes standard callback and data.
Abstract base class for Open Inventor sensors.
Definition SoSensor.h:100
void SoSensorCB(void *data, SoSensor *sensor)
This typedef defines the calling sequence for all callbacks from sensors.
