Notes
Utilisez cet événement lorsque votre application gère sa propre structure de données, synchronisée avec celle de InkAnalyzerBase. Cet événement se produit pendant la phase de rapprochement de l'analyse d'entrée manuscrite ou lorsqu'une méthode d'analyse d'entrée manuscrite a déplacé un ContextNodeBase dans la collection SubNodes de son nœud parent.
Pour plus d'informations sur la synchronisation des données d'application avec le InkAnalyzerBase, consultez Data Proxy with Ink Analysis.
