JScript no admite eventos.
Comentarios
Utilice este evento cuando la aplicación mantenga su propia estructura de datos, que está sincronizada con la del objeto InkAnalyzerBase. Este evento se produce durante la fase de conciliación del análisis de entrada manuscrita o en respuesta a un método del analizador de entrada manuscrita que quita un objeto ContextLinkBase de un objeto ContextNodeBase.
Para obtener más información sobre la sincronización entre los datos de la aplicación y InkAnalyzerBase, vea Data Proxy with Ink Analysis.
Ejemplos
En el ejemplo siguiente se define un método, AttachDataProxyEventHandlers, que asocia los controladores de eventos del proxy de datos a un objeto InkAnalyzerBase, baseInkAnalyzer.
Private Sub AttachDataProxyEventHandlers()
' If the document model supports on demand data proxy, then add an
' event handler for the PopulateContextNodeBase event. This event is raised
' when the InkAnalyzerBase accesses a partially populated ContextNodeBase
' created by the document model.
If Me.baseDocumentModel.SupportsOnDemandDataProxy Then
AddHandler Me.baseInkAnalyzer.PopulateContextNodeBase, AddressOf Me.PopulateContextNodeBase
End If
' Add the other data proxy related event handlers. These events are raised
' by the InkAnalyzer to communicate parsing results to the document model.

En el ejemplo siguiente se define el método, RemoveContextNodeLinkBase, que controla el evento ContextNodeLinkDeletingBase. La información del evento se pasa al objeto del modelo de documento, baseDocumentModel.
En este ejemplo no se proporciona la definición del modelo de documento ni se muestra cómo procesa la información que se le pasa.
