Заметки

Use this event when your application maintains its own data structure, which is synchronized with that of the InkAnalyzer. This event occurs during the reconcile phase of ink analysis, or in response to an InkAnalyzer method that moves a ContextNode within its parent's SubNodes collection.

For more information about synchronizing your application data with the InkAnalyzer, see Data Proxy with Ink Analysis.

Примеры

This example defines a method, AttachDataProxyEventHandlers, that attaches data proxy event handlers to an 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.

The following example defines the method, MoveContextNodeToPosition, that handles the ContextNodeMovingToPosition event. The event information is passed to the document model object, theDocumentModel.

This example does not provide the definition of the document model or demonstrate how it processes the information passed to it.

'/ <summary>
'/ Handles the InkAnalyzer.ContextNodeMovingToPosition event.
'/ </summary>
'/ <param name="sender">The source of the event.</param>
'/ <param name="e">The event data.</param>
Private Sub MoveContextNodeToPosition( _
    ByVal sender As Object, _
    ByVal e As Microsoft.Ink.ContextNodeMovingToPositionEventArgs)

    Me.theDocumentModel.MoveNode(e.SubNodeToMove, e.NewIndex)

End Sub 'MoveContextNodeToPosition

        /// <summary>
        /// Handles the InkAnalyzer.ContextNodeMovingToPosition event.
        /// </summary>
        /// <param name="sender">The source of the event.</param>
        /// <param name="e">The event data.</param>
        private void MoveContextNodeToPosition(
            object sender, Microsoft.Ink.ContextNodeMovingToPositionEventArgs e)
        {
            this.theDocumentModel.MoveNode(e.SubNodeToMove, e.NewIndex);
        }
