InkAnalyzerBase.ContextNodePropertiesUpdatedBase Event

Article
12/12/2007

Occurs after the ink analyzer updates one or more of the properties of a ContextNodeBase.

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

Syntax

'Declaration
Public Event ContextNodePropertiesUpdatedBase As ContextNodePropertiesUpdatedBaseEventHandler
'Usage
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)

In JScript, you can handle the events defined by a class, but you cannot define your own.

Not applicable.

Remarks

Use this event when your application maintains its own data structure, which is synchronized with that of the InkAnalyzerBase. This event occurs during the reconcile phase of ink analysis, or in response to an ink analyzer method that changes the properties of a ContextNodeBase.

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

Example

The following example defines a method, AttachDataProxyEventHandlers, that attaches data proxy event handlers to an 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
    AddHandler Me.baseInkAnalyzer.ContextNodeDeletingBase, _
        AddressOf Me.RemoveContextNodeBase
    AddHandler Me.baseInkAnalyzer.ContextNodeLinkAddingBase, _
        AddressOf Me.AddContextNodeLinkBase
    AddHandler Me.baseInkAnalyzer.ContextNodeLinkDeletingBase, _
        AddressOf Me.RemoveContextNodeLinkBase

        AddressOf Me.MoveContextNodeBaseToPosition

        AddressOf Me.UpdateContextNodeBaseProperties

        AddressOf Me.ReparentContextNodeBase

The following example defines the method, UpdateContextNodeBaseProperties, that handles the ContextNodePropertiesUpdatedBase event. The event information is passed to the document model object, baseDocumentModel.

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

''' <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

/// <summary>

    object sender,
