Notes

Utilisez cet événement lorsque votre application gère sa propre structure de données, synchronisée avec celle du InkAnalyzer. Cet événement se produit pendant la phase de rapprochement de l'analyse d'entrée manuscrite ou en réponse à une méthode InkAnalyzer qui ajoute un nouveau ContextLink à un ContextNode.

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

Exemples

Cet exemple définit une méthode, AttachDataProxyEventHandlers, qui attache des gestionnaires d'événements du proxy de données à un InkAnalyzer, theInkAnalyzer.

    ' event handler for the PopulateContextNode event. This event is raised
    ' when the InkAnalyzer accesses a partially populated ContextNode created
    ' by the document model.
    If Me.theDocumentModel.SupportsOnDemandDataProxy Then
        AddHandler Me.theInkAnalyzer.PopulateContextNode, AddressOf Me.PopulateContextNode
    End If

    ' Add the other data proxy related event handlers. These events are raised
    ' by the InkAnalyzer to communicate ink analysis results to the document model.

L'exemple suivant définit la méthode AddContextNodeLink, qui gère l'événement ContextNodeLinkAdding. Les informations sur l'événement sont passées à l'objet de modèle de document, theDocumentModel.

Cet exemple ne fournit pas la définition du modèle de document et ne montre pas comment traiter les informations qui lui sont passées.
