InkAnalyzer.ContextNodePropertiesUpdated Event
Occurs after the InkAnalyzer updates one or more of the properties of a ContextNode.
Namespace: Microsoft.Ink
Assembly: Microsoft.Ink.Analysis (in Microsoft.Ink.Analysis.dll)
Syntax
'Declaration
Public Event ContextNodePropertiesUpdated As ContextNodePropertiesUpdatedEventHandler
'Usage
Dim instance As InkAnalyzer
Dim handler As ContextNodePropertiesUpdatedEventHandler
AddHandler instance.ContextNodePropertiesUpdated, handler
public event ContextNodePropertiesUpdatedEventHandler ContextNodePropertiesUpdated
public:
event ContextNodePropertiesUpdatedEventHandler^ ContextNodePropertiesUpdated {
void add (ContextNodePropertiesUpdatedEventHandler^ value);
void remove (ContextNodePropertiesUpdatedEventHandler^ value);
}
JScript does not support events.
Remarks
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 changes the properties of a ContextNode.
For more information about synchronizing your application data with the InkAnalyzer, see Data Proxy with Ink Analysis.
Examples
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, UpdateContextNodeProperties, that handles the ContextNodePropertiesUpdated 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.
