Hi,   As the stage is no longer a Stage Object and stage property has been removed from the DisplayObjects, how can we know when a DisplayObject is on the stage or not ?   I asked few days ago about dispatching an event when objects are added to the stage or remove (like in AS3), but I don't find the events dispatched by DisplayObject in the documentation, is there a place to find them ?   Last question: As stage is only a classic Container now, it seems possible to change the stage on the fly c
