InkAnalyzer.ResultsUpdated Event

Article
12/08/2012

Occurs when the final analysis stage has completed.

Namespace: System.Windows.Ink
Assembly: IAWinFX (in IAWinFX.dll)

Syntax

'Declaration
Public Event ResultsUpdated As ResultsUpdatedEventHandler
'Usage
Dim instance As InkAnalyzer 
Dim handler As ResultsUpdatedEventHandler 

AddHandler instance.ResultsUpdated, handler

public event ResultsUpdatedEventHandler ResultsUpdated

public:
 event ResultsUpdatedEventHandler^ ResultsUpdated {
    void add (ResultsUpdatedEventHandler^ value);
    void remove (ResultsUpdatedEventHandler^ value);
}

JScript does not support events.

Remarks

The InkAnalyzer raises the ResultsUpdated event after the event reconciles the results for the final analysis stage.

If your application calls BackgroundAnalyze, this event signals when analysis results are ready.

If your application maintains its own synchronized data structure with that of the InkAnalyzer, the ResultsUpdated event indicates that the InkAnalyzer has finished the changes to internal data that are required by the current analysis stage.

Lock your data structure when the InkAnalyzer raises the InkAnalyzerStateChanging event. Changes to your data structure during this phase of analysis may cause errors in ink analysis and synchronization. You can unlock your data structure when the InkAnalyzer raises the IntermediateResults or Results event.

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

Examples

This example defines a method named AttachDataProxyEventHandlers that attaches data proxy event handlers to an InkAnalyzer named 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. 
    AddHandler Me.theInkAnalyzer.ContextNodeCreated, AddressOf Me.AddContextNode
    AddHandler Me.theInkAnalyzer.ContextNodeDeleting, AddressOf Me.RemoveContextNode
    AddHandler Me.theInkAnalyzer.ContextNodeLinkAdding, AddressOf Me.AddContextNodeLink
    AddHandler Me.theInkAnalyzer.ContextNodeLinkDeleting, AddressOf Me.RemoveContextNodeLink
    AddHandler Me.theInkAnalyzer.ContextNodeMovingToPosition, AddressOf Me.MoveContextNodeToPosition
    AddHandler Me.theInkAnalyzer.ContextNodePropertiesUpdated, AddressOf Me.UpdateContextNodeProperties
    AddHandler Me.theInkAnalyzer.ContextNodeReparenting, AddressOf Me.ReparentContextNode
    AddHandler Me.theInkAnalyzer.InkAnalyzerStateChanging, AddressOf Me.InkAnalyzer_StateChanging

The following example defines the method, ResultsAvailable, that handles the IntermediateResults and Results events. The event information is passed to the document model object, named theDocumentModel.

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

'/ Handles the InkAnalyzer.Results and InkAnalyzer.IntermediateResults events. 
'/ </summary> 
'/ <param name="sender">The source of the event.</param> 
'/ <param name="e">The event data.</param> 
Private Sub ResultsAvailable(ByVal sender As Object, ByVal e As ResultsUpdatedEventArgs) 
    Me.theDocumentModel.ResultsAvailable(CType(sender, InkAnalyzer))

/// <summary>
