When event queue for drawing gets full:
wait: event processing waits for vis manager to catch up.
discard: events are discarded for drawing.
Available at all Geant4 states.
Parameters
wait
type s
Omittable : default value = wait
Parameter candidates : wait discard
maxEventQueueSize [maxSize]
Defines maximum event queue size. N <=0 means "unlimited".
If adding an event to the visualisation event queue would cause the queue size to exceed this value:
if actionOnEventQueueFull==wait the worker threads are paused for a short time to give the visualisation manager a chance to catch up.
if actionOnEventQueueFull==discard the event is discarded for drawing.
