Camelot: OpApplyGlobalAffect Class Reference

Scans through all object nodes of all object trees in all documents, passing the user object change parameter to every node it comes accross. The tree scans are depth first. This is a useful operation for other ops to derive themselves off.

void	DoAffectChange (ObjChangeParam pObjChange, Document pSearchDoc=NULL)
	Scans through all object nodes of all object trees in all documents, passing the user object change parameter to every node it comes accross. The tree scans are depth first. This is a useful operation for other ops to derive themselves off.
virtual void	AffectNode (Document , Node , ObjChangeParam *)
	This function checks for text story nodes. If the entry node is one, the node will be reformated and redrawn.
