Detailed Description
An interface for accessibility events listened to by in-process accessibility clients, which can be used to find out how to get accessibility and DOM interfaces for the event and its target.
To listen to in-process accessibility invents, make your object an nsIObserver, and listen for accessible-event by using code something like this: nsCOMPtr<nsIObserverService> observerService = do_GetService("@mozilla.org/observer-service;1", &rv); if (NS_SUCCEEDED(rv)) rv = observerService->AddObserver(this, "accessible-event", PR_TRUE);
