Заметки

When you create a ContextNodeDeletingEventHandler 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.

Примеры

The following example defines the method, RemoveContextNode, that handles the ContextNodeDeleting 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.ContextNodeDeleting event.
'/ </summary>
'/ <param name="sender">The source of the event.</param>
'/ <param name="e">The event data.</param>
Private Sub RemoveContextNode( _
    ByVal sender As Object, _
    ByVal e As Microsoft.Ink.ContextNodeDeletingEventArgs)

    ' Do not remove unclassified ink nodes from the document model.
    If Microsoft.Ink.ContextNodeType.UnclassifiedInk _
        <> e.NodeToBeDeleted.Type Then

        Me.theDocumentModel.RemoveNode(e.NodeToBeDeleted)
    End If

End Sub 'RemoveContextNode

        /// <summary>
        /// Handles the InkAnalyzer.ContextNodeDeleting event.
        /// </summary>
        /// <param name="sender">The source of the event.</param>
        /// <param name="e">The event data.</param>
        private void RemoveContextNode(
            object sender, Microsoft.Ink.ContextNodeDeletingEventArgs e)
        {
            // Do not remove unclassified ink nodes from the document model.
            if (Microsoft.Ink.ContextNodeType.UnclassifiedInk
                != e.NodeToBeDeleted.Type)
            {
                this.theDocumentModel.RemoveNode(e.NodeToBeDeleted);
            }
        }
