範例

下列範例示範如何變更的背景色彩TextBoxTextBox會擷取並釋放手寫筆事件。The following example demonstrates how to change the background color of a TextBox when the TextBox captures and releases stylus events. 此範例假設是文字方塊,稱為textBox1,且GotStylusCaptureLostStylusCapture事件都已連接的範例中的事件處理常式。This example assumes that there is a textbox called textBox1, and that the GotStylusCapture and LostStylusCapture events are connected to the event handlers in the example.

void textbox1_LostStylusCapture(object sender, StylusEventArgs e)
{
    textbox1.Background = Brushes.White;
}

void textbox1_GotStylusCapture(object sender, StylusEventArgs e)
{
    textbox1.Background = Brushes.Red;
}
Private Sub textbox1_LostStylusCapture(ByVal sender As Object, ByVal e As StylusEventArgs) _
    Handles textbox1.LostStylusCapture

    textbox1.Background = Brushes.White

End Sub 'textbox1_LostStylusCapture


Private Sub textbox1_GotStylusCapture(ByVal sender As Object, ByVal e As StylusEventArgs) _
    Handles textbox1.GotStylusCapture

    textbox1.Background = Brushes.Red

End Sub 'textbox1_GotStylusCapture

備註

這是附加的事件。This is an attached event. WPFWPF 將附加的事件實作為路由事件。implements attached events as routed events. 基本上,附加的事件是XAMLXAML用來參考處理的事件未這麼做的物件本身會定義事件的語言概念。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 進一步擴充附加的事件的功能,讓它可以周遊的路由。further expands an attached event's capabilities, allowing it to traverse a route. 附加的事件並沒有直接處理語法在程式碼若要附加的程式碼中的路由事件處理常式,使用指定的新增 * 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 < 附加事件概觀For details, see Attached Events Overview.
