Article
10/19/2012

Represents the method that will handle the PopulateContextNode event of an InkAnalyzer.

Namespace: Microsoft.Ink
Assembly: Microsoft.Ink.Analysis (in Microsoft.Ink.Analysis.dll)

Syntax

'Declaration
Public Delegate Sub PopulateContextNodeEventHandler ( _
    sender As Object, _
    e As PopulateContextNodeEventArgs _
)
'Usage
Dim instance As New PopulateContextNodeEventHandler(AddressOf HandlerMethod)

public delegate void PopulateContextNodeEventHandler(
    Object sender,
    PopulateContextNodeEventArgs e
)

public delegate void PopulateContextNodeEventHandler(
    Object^ sender, 
    PopulateContextNodeEventArgs^ e
)

JScript does not support delegates.

Parameters

sender
Type: System.Object

The source of the event.

e
Type: Microsoft.Ink.PopulateContextNodeEventArgs

The event data.

Remarks

When you create a PopulateContextNodeEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events and Delegates.

Examples

The following example defines the method, PopulateContextNode, that handles the PopulateContextNode 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.

'/ <summary> 
'/ Handles the InkAnalyzer.PopulateContextNode event. 
'/ </summary> 
'/ <param name="sender">The source of the event.</param> 
'/ <param name="e">The event data.</param> 
'/ <remarks> 
'/ This event handler fully populates a ContextNode from the document model. 
'/ The InkAnalyzer calls this event handler when it accesses a partially 
'/ populated ContextNode created by the document model. 
'/ </remarks> 
Private Sub PopulateContextNode( _
    ByVal sender As Object, _
    ByVal e As Microsoft.Ink.PopulateContextNodeEventArgs)

    Me.theDocumentModel.PopulateNode(e.NodeToPopulate, _
        CType(sender, Microsoft.Ink.InkAnalyzer))

End Sub 'PopulateContextNode

        /// <summary> 
        /// Handles the InkAnalyzer.PopulateContextNode event. 
        /// </summary> 
        /// <param name="sender">The source of the event.</param>

        /// </remarks> 
        private void PopulateContextNode(
            object sender, Microsoft.Ink.PopulateContextNodeEventArgs e)
        {
            this.theDocumentModel.PopulateNode(
                e.NodeToPopulate, (Microsoft.Ink.InkAnalyzer)sender);
        }
