Articolo
10/29/2008

Aggiornamento: novembre 2007

Si verifica dopo che l'analizzatore dell'input penna aggiorna una o più proprietà di un oggetto ContextNodeBase.

Spazio dei nomi: System.Windows.Ink.AnalysisCore
Assembly: IACore (in IACore.dll)

Sintassi

'Dichiarazione
Public Event ContextNodePropertiesUpdatedBase As ContextNodePropertiesUpdatedBaseEventHandler
'Utilizzo
Dim instance As InkAnalyzerBase
Dim handler As ContextNodePropertiesUpdatedBaseEventHandler

AddHandler instance.ContextNodePropertiesUpdatedBase, handler

public event ContextNodePropertiesUpdatedBaseEventHandler ContextNodePropertiesUpdatedBase

public:
 event ContextNodePropertiesUpdatedBaseEventHandler^ ContextNodePropertiesUpdatedBase {
    void add (ContextNodePropertiesUpdatedBaseEventHandler^ value);
    void remove (ContextNodePropertiesUpdatedBaseEventHandler^ value);
}

/** @event */
public void add_ContextNodePropertiesUpdatedBase (ContextNodePropertiesUpdatedBaseEventHandler value)
/** @event */
public void remove_ContextNodePropertiesUpdatedBase (ContextNodePropertiesUpdatedBaseEventHandler value)

JScript non supporta gli eventi.

Note

Utilizzare questo evento nel caso in cui l'applicazione gestisce una struttura di dati personalizzata, sincronizzata con quella dell'oggetto InkAnalyzerBase. Questo evento si verifica durante la fase di riconciliazione dell'analisi dell'input penna o in risposta a un metodo dell'analizzatore dell'input penna che modifica le proprietà di un oggetto ContextNodeBase.

Per ulteriori informazioni sulla sincronizzazione dei dati applicazioni con InkAnalyzerBase, vedere Data Proxy with Ink Analysis.

Esempi

Nell'esempio seguente viene definito un metodo, AttachDataProxyEventHandlers, che associa i gestori di eventi del proxy di dati a un oggetto 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.
    AddHandler Me.baseInkAnalyzer.ContextNodeCreatedBase, _
        AddressOf Me.AddContextNodeBase

Nell'esempio seguente viene definito il metodo, UpdateContextNodeBaseProperties, che gestisce l'evento ContextNodePropertiesUpdatedBase. Le informazioni relative all'evento vengono passate all'oggetto modello di documento, baseDocumentModel.

In questo esempio non viene fornita la definizione del modello di documento né viene illustrato come vengono elaborate le informazioni passate a tale modello.

''' <summary>
''' Handles the InkAnalyzerBase.ContextNodePropertiesUpdatedBase event.
''' </summary>
''' <param name="sender">The source of the event.</param>
''' <param name="e">The event data.</param>
Private Sub UpdateContextNodeBaseProperties( _
    ByVal sender As Object, _
    ByVal e As System.Windows.Ink.AnalysisCore.ContextNodePropertiesUpdatedBaseEventArgs)

    Me.baseDocumentModel.UpdateNodeProperties(e.UpdatedNode)

End Sub 'UpdateContextNodeBaseProperties
