Hover event time-count

 var eventBus = viewer.get('eventBus');
			       eventBus.on('element.hover', function(e) {

the hover event will be triggered immediately even the mouse just slip by the element. is there any parameter to config how long after the mouse real hover/static on the element to trigger the event?

No, there is no such parameter. You can easily build that stuff yourself, i.e. by using setTimeout.

Thanks a lot for your help. nikku.
