InkAnalyzerBase.ContextNodeLinkDeletingBase-Ereignis
Tritt auf, bevor das Freihandanalysemodul ContextLinkBase zwischen zwei ContextNodeBase-Objekten löscht.
Namespace: System.Windows.Ink.AnalysisCore
Assembly: IACore (in IACore.dll)

JScript unterstützt keine Ereignisse.
Hinweise
Verwenden Sie dieses Ereignis, wenn die Anwendung eine eigene Datenstruktur verwaltet, die mit der Datenstruktur von InkAnalyzerBase synchronisiert wird. Dieses Ereignis tritt während der Abgleichphase der Freihandanalyse oder als Antwort auf eine Freihandanalysemethode auf, die einen ContextLinkBase aus einem ContextNodeBase löscht.
Weitere Informationen zum Synchronisieren von Anwendungsdaten mit InkAnalyzerBase finden Sie unter Data Proxy with Ink Analysis.
Beispiele
Im folgenden Beispiel wird die Methode AttachDataProxyEventHandlers definiert, die Datenproxyereignishandler an die InkAnalyzerBasebaseInkAnalyzer anfügt.
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.

Im folgenden Beispiel wird die RemoveContextNodeLinkBase-Methode definiert, die das ContextNodeLinkDeletingBase-Ereignis behandelt. Die Ereignisinformationen werden an das Dokumentmodellobjekt baseDocumentModel übergeben.
Dieses Beispiel liefert nicht die Definition des Dokumentmodells und veranschaulicht nicht, wie die übergebenen Informationen verarbeitet werden.
