ContextNodeCreatedEventHandler 委托

表示将处理 InkAnalyzerContextNodeCreated 事件的方法。

命名空间:  Microsoft.Ink
程序集:  Microsoft.Ink.Analysis(在 Microsoft.Ink.Analysis.dll 中)

语法

声明
Public Delegate Sub ContextNodeCreatedEventHandler ( _
    sender As Object, _
    e As ContextNodeCreatedEventArgs _
)
用法
Dim instance As New ContextNodeCreatedEventHandler(AddressOf HandlerMethod)
public delegate void ContextNodeCreatedEventHandler(
    Object sender,
    ContextNodeCreatedEventArgs e
)
public delegate void ContextNodeCreatedEventHandler(
    Object^ sender, 
    ContextNodeCreatedEventArgs^ e
)
/** @delegate */
public delegate void ContextNodeCreatedEventHandler(
    Object sender,
    ContextNodeCreatedEventArgs e
)
JScript 不支持委托。

参数

备注

创建 ContextNodeCreatedEventHandler 委托时,需要标识处理该事件的方法。若要将该事件与事件处理程序关联,请将该委托的一个实例添加到事件中。除非移除了该委托,否则每当发生该事件时就会调用此事件处理程序。有关事件处理程序委托的更多信息,请参见 Events and Delegates(事件和委托)。

示例

下面的示例定义 AddContextNode 方法,用以处理 ContextNodeCreated 事件。事件信息将传递给文档模型对象 theDocumentModel。

此示例不提供文档模型的定义,也不演示文档模型如何处理传入的信息。

'/ <summary>
'/ Handles the InkAnalyzer.ContextNodeCreated event.
'/ </summary>
'/ <param name="sender">The source of the event.</param>
'/ <param name="e">The event data.</param>
'/ <remarks>
'/ Note: when this event is fired, the ContextNode has not been populated
'/ with extended and other properties. Handle the ContextNodePropertiesUpdated
'/ event to populate the corresponding ContextNode in the document model.
'/ </remarks>
Private Sub AddContextNode( _
    ByVal sender As Object, _
    ByVal e As Microsoft.Ink.ContextNodeCreatedEventArgs)

    ' Do not add unclassified ink nodes to the document model.
    If Microsoft.Ink.ContextNodeType.UnclassifiedInk _
        <> e.NodeCreated.Type Then

        Me.theDocumentModel.AddNode(e.NodeCreated)
    End If

End Sub 'AddContextNode

        /// <summary>
        /// Handles the InkAnalyzer.ContextNodeCreated event.

        private void AddContextNode(
            object sender, Microsoft.Ink.ContextNodeCreatedEventArgs e)
        {
            // Do not add unclassified ink nodes to the document model.
            if (Microsoft.Ink.ContextNodeType.UnclassifiedInk
                != e.NodeCreated.Type)
            {
                this.theDocumentModel.AddNode(e.NodeCreated);
            }
        }
