範例

下列範例示範當使用者放開手寫筆上的圓筒按鈕時, 如何複製選取的文字。The following example demonstrates how to copy the selected text when the user releases the barrel button on a stylus. 這個範例假設有一個TextBox呼叫textBox1, 而且該StylusButtonUp事件已連接到事件處理常式。This example assumes that there is a TextBox called textBox1, and that the StylusButtonUp event is connected to the event handlers.

void textbox1_StylusButtonUp(object sender, StylusButtonEventArgs e)
{
    if (e.StylusButton.Guid != StylusPointProperties.BarrelButton.Id)
    {
        return;
    }

    if (textbox1.SelectedText == "")
    {
        return;
    }

    Clipboard.SetDataObject(textbox1.SelectedText);
}
Private Sub textbox1_StylusButtonUp(ByVal sender As Object, ByVal e As StylusButtonEventArgs) _
    Handles textbox1.StylusButtonUp

    If e.StylusButton.Guid <> StylusPointProperties.BarrelButton.Id Then
        Return
    End If

    If textbox1.SelectedText = "" Then
        Return
    End If

    Clipboard.SetDataObject(textbox1.SelectedText)

End Sub

備註

這是附加事件。This is an attached event. WPFWPF將附加事件實作為路由事件。implements attached events as routed events. 附加事件基本上是一種XAMLXAML語言概念, 用來參考在不會定義事件的物件上處理的事件。An attached event is, fundamentally, a XAMLXAML language concept used to reference events that are handled on objects that do not, themselves, define events. WPFWPF進一步擴充附加事件的功能, 讓它能夠跨越路由。further expands an attached event's capabilities, allowing it to traverse a route. 附加事件在程式碼中沒有直接處理語法;若要在程式碼中附加路由事件的處理常式, 請使用指定的 Add * 處理常式方法。Attached events do not have a direct handling syntax in code; to attach handlers for a routed event in code, use a designated Add*Handler method. 如需詳細資訊, 請參閱附加事件總覽For details, see Attached Events Overview.
