RenderCallback Class Reference

Provide a base class for handling callbacks from RenderTree Notes: RenderTree function calls the BeforeNode function in this class when it's about to render any Node. Derive from this class and implement Callback to provide specialised processing of nodes during rendering Derived versions of Callback can: Prevent the node being rendered Set attributes Set subrender contexts Accumulate their own info about the render sequence.
