It sounds like you want to be able to register on a object high up in the DisplayObject tree -- such as the Stage, the SystemManager, or the Application -- and detect when DisplayObjects have been added anywhere below, no matter how deep down. To figure out how to do this, let's consider the four different events that convey information about children getting added: Event.ADDED: Dispatched from DisplayObject that was added. Bubbles up the parent chain. Event.ADDED_TO_STAGE: Dispatched from DisplayObject that was added. Doesn't bubble up the parent chain. FlexEvent.ADD: Dispatched from a UIComponent that was added as a content child to a Container.Doesn't bubble up the parent chain. FlexEvent.CHILD_ADD: Dispatched from a Container to which a content child was added. Doesn't bubble up the parent chain. Also, keep in mind that, although not all events bubble, they all go through a "capture" phase that is the opposite of bubbling -- starting at the SystemManager and going down the parent chain to the event target. To listen to events passing through a DisplayObject during the capture phase, set the useCapture parameter of addEventListener() to true. So I think your choices are either to listen on Stage, SystemManager, or Application for any of these four events on their way down to the target during the capture phase, or for Event.ADDED on these objects as it -- the only one that bubbles -- bubbles up.
