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 créé un ContextNodeBase.

Lorsque l'analyseur d'entrée manuscrite crée un nœud de contexte, ce dernier ne contient pas de traits ou de liens vers d'autres nœuds de contexte et ses propriétés ne sont pas nécessairement toutes définies. De plus, le nouveau nœud de contexte est ajouté à la fin de la collection SubNodes de son parent. Après cet événement, l'analyseur d'entrée manuscrite peut déclencher les événements suivants.

Pour plus d'informations sur la synchronisation des données d'application avec le InkAnalyzerBase, consultez Data Proxy with Ink Analysis.
