範例
下列範例示範如何在 TextBox TextBox 捕捉和釋放手寫筆事件時,變更的背景色彩。The following example demonstrates how to change the background color of a TextBox when the TextBox captures and releases stylus events. 這個範例假設有一個名為的 textbox textBox1
,而且 GotStylusCapture 和事件已 LostStylusCapture 連接到事件處理常式。This example assumes that there is a textbox called textBox1
, and that the GotStylusCapture and LostStylusCapture events are connected to event handlers.
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
Private Sub textbox1_GotStylusCapture(ByVal sender As Object, ByVal e As StylusEventArgs) _
Handles textbox1.GotStylusCapture
textbox1.Background = Brushes.Red
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。Attached events are, 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。The WPFWPF 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.
