deferredDelete(self) → bool¶: The item is scheduled to be deleted. E.g. if deleteLater() is called when item is in Populating state (createChildren() running in another thread), the deferredDelete() returns True and item will be deleted once Populating finished. Items with slow reateChildren() (for example network or database based) may check during createChildren() if deferredDelete() returns True and return from createChildren() immediately because result will be useless. *
