InkAnalyzer.PopulateContextNode (Evento)
Actualización: noviembre 2007
Se produce antes de que el objeto InkAnalyzer realice el análisis dentro de la región de un objeto ContextNode rellenado parcialmente.
Espacio de nombres: Microsoft.Ink
Ensamblado: Microsoft.Ink.Analysis (en Microsoft.Ink.Analysis.dll)

JScript no admite eventos.
Comentarios
Utilice este evento cuando la aplicación mantenga su propia estructura de datos, que está sincronizada con la del objeto InkAnalyzer. Cuando el objeto InkAnalyzer provoca este evento, la aplicación debería rellenar la propiedad PopulateContextNodeEventArgs.NodeToPopulate. Durante la fase de análisis, el objeto InkAnalyzer provoca este evento para obtener información sobre las áreas en las que se está analizando la entrada manuscrita.
Si el documento contiene vínculos de la propiedad NodeToPopulate, la aplicación debería crear y agregar estos vínculos. Este proceso requiere que los nodos de origen y destino, incluso sus antecesores, estén totalmente rellenos antes de que se cierre el controlador de este evento.
Para obtener más información sobre la sincronización de los datos de la aplicación con el objeto InkAnalyzer, vea Data Proxy with Ink Analysis.
Durante el análisis del segundo plano, el objeto InkAnalyzer provoca este evento después de provocar el evento InkAnalyzerStateChanging.
Ejemplos
En este ejemplo se define un método, AttachDataProxyEventHandlers, que asocia los controladores de eventos del proxy de datos a un objeto InkAnalyzer, theInkAnalyzer.
Private Sub AttachDataProxyEventHandlers()
' If the document model supports on demand data proxy, then add an
' 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.

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