Evento InkAnalyzerBase.ContextNodeReparentingBase
Aggiornamento: novembre 2007
Si verifica prima che l'analizzatore dell'input penna sposti un oggetto ContextNodeBase modificandone il nodo padre.
Spazio dei nomi: System.Windows.Ink.AnalysisCore
Assembly: IACore (in IACore.dll)
Sintassi
'Dichiarazione
Public Event ContextNodeReparentingBase As ContextNodeReparentingBaseEventHandler
'Utilizzo
Dim instance As InkAnalyzerBase
Dim handler As ContextNodeReparentingBaseEventHandler
AddHandler instance.ContextNodeReparentingBase, handler
public event ContextNodeReparentingBaseEventHandler ContextNodeReparentingBase
public:
event ContextNodeReparentingBaseEventHandler^ ContextNodeReparentingBase {
void add (ContextNodeReparentingBaseEventHandler^ value);
void remove (ContextNodeReparentingBaseEventHandler^ value);
}
/** @event */
public void add_ContextNodeReparentingBase (ContextNodeReparentingBaseEventHandler value)
/** @event */
public void remove_ContextNodeReparentingBase (ContextNodeReparentingBaseEventHandler 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 sposta un oggetto ContextNodeBase da un insieme ContextNodeBase.SubNodes a un altro.
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.

Nell'esempio seguente viene definito il metodo, ReparentContextNodeBase, che gestisce l'evento ContextNodeReparentingBase. ReparentContextNode passa le informazioni sull'evento 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.
