AcGiDrawableEvent Class   

drawable.h

AcGiDrawableEvent manages a set of AcGiDrawableReactors and sends notifications to them when certain events occur. Access is through a singleton instance of this class, acgiDrawableEvent. Clients of AcGiDrawableEvent fall into three categories:

1. Any client interested in making use of AcGiDrawableReactor must add and remove their reactor through addReactor() and removeReactor().
2. AcGiDrawable-derived clients may use this class to notify graphics systems of modifications and erasures of their graphics.
3. Graphics systems may use this class to notify interested listeners (e.g. AcGiDrawStream) of regen begin/end events.
