InkAnalyzerBase.ContextNodeMovingToPositionBase Event

Occurs before the ink analyzer moves a ContextNodeBase to a new position within its parent node's SubNodes collection.

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

Syntax

'Declaration
Public Event ContextNodeMovingToPositionBase As ContextNodeMovingToPositionBaseEventHandler
'Usage
Dim instance As InkAnalyzerBase 
Dim handler As ContextNodeMovingToPositionBaseEventHandler 

AddHandler instance.ContextNodeMovingToPositionBase, handler
public event ContextNodeMovingToPositionBaseEventHandler ContextNodeMovingToPositionBase
public:
 event ContextNodeMovingToPositionBaseEventHandler^ ContextNodeMovingToPositionBase {
    void add (ContextNodeMovingToPositionBaseEventHandler^ value);
    void remove (ContextNodeMovingToPositionBaseEventHandler^ 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 moves a ContextNodeBase within its parent node's SubNodes collection.

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, MoveContextNodeBaseToPosition, that handles the ContextNodeMovingToPositionBase 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.
