Tritt auf, bevor das Freihandanalysemodul ContextLinkBase zwischen zwei ContextNodeBase-Objekten hinzufügt.

Namespace: System.Windows.Ink.AnalysisCore
Assembly: IACore (in IACore.dll)

Syntax

'Declaration
Public Event ContextNodeLinkAddingBase As ContextNodeLinkAddingBaseEventHandler
'Usage
Dim instance As InkAnalyzerBase
Dim handler As ContextNodeLinkAddingBaseEventHandler

AddHandler instance.ContextNodeLinkAddingBase, handler

public event ContextNodeLinkAddingBaseEventHandler ContextNodeLinkAddingBase

public:
 event ContextNodeLinkAddingBaseEventHandler^ ContextNodeLinkAddingBase {
    void add (ContextNodeLinkAddingBaseEventHandler^ value);
    void remove (ContextNodeLinkAddingBaseEventHandler^ value);
}

/** @event */
public void add_ContextNodeLinkAddingBase (ContextNodeLinkAddingBaseEventHandler value)
/** @event */
public void remove_ContextNodeLinkAddingBase (ContextNodeLinkAddingBaseEventHandler value)

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 neuen ContextLinkBase zu einem ContextNodeBase hinzufügt.

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.
    AddHandler Me.baseInkAnalyzer.ContextNodeCreatedBase, _
        AddressOf Me.AddContextNodeBase

Im folgenden Beispiel wird die AddContextNodeLinkBase-Methode definiert, die das ContextNodeLinkAddingBase-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.

    ByVal sender As Object, _
    ByVal e As System.Windows.Ink.AnalysisCore.ContextNodeLinkAddingBaseEventArgs)

    Me.baseDocumentModel.AddLink(e.LinkToBeAdded)

End Sub 'AddContextNodeLinkBase
