Is there a way to determine which event listeners are registered with a display object? I want to remove all event listeners from a display object so that I can assign new ones based on context changes in the application.

jeceuyper is right …
a side not though:
DisplayObjectextendsEventDispatcher, which already does implementIEventDispatcher… so to be more precise: you need to overrideaddEventListenerandremoveEventListenerto keep track of the listeners …a few technical details: i suggest you use
Dictionaryto store the handler functions … a bit slower for insertion, but much faster for removal … also,Dictionarysupports weak references, which is quite important in the case of event handling … also keep in mind, thatuseCaptureallows to add the same handler twice …good luck then … 😉
