InkAnalyzerBase.ContextNodePropertiesUpdatedBase Event
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);
}
JScript does not support events.
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.
Examples
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.

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.
