範例

下列範例示範如何將記錄在手寫筆的座標,即使使用者將手寫筆離開TextBoxThe following example demonstrates how to record the coordinates of the stylus, even if the stylus leaves the bounds of a TextBox. 這個範例假設有TextBoxtextBox1,且StylusDownStylusUp,和StylusMove事件都已連接至事件處理常式。This example assumes that there is a TextBox called textBox1, and that the StylusDown, StylusUp, and StylusMove events are connected to event handlers.

void textbox1_StylusDown(object sender, StylusDownEventArgs e)
{
    Stylus.Capture(textbox1);
}

void textbox1_StylusMove(object sender, StylusEventArgs e)
{
    Point pos = e.GetPosition(textbox1);
    textbox1.AppendText("X: " + pos.X + " Y: " + pos.Y + "\n");
}

void textbox1_StylusUp(object sender, StylusEventArgs e)
{
    Stylus.Capture(textbox1, CaptureMode.None);
}
Private Sub textbox1_StylusDown(ByVal sender As Object, ByVal e As System.Windows.Input.StylusDownEventArgs) _
    Handles textbox1.StylusDown

    Stylus.Capture(textbox1)

End Sub 'textbox1_StylusDown


Private Sub textbox1_StylusMove(ByVal sender As Object, ByVal e As StylusEventArgs) _
    Handles textbox1.StylusMove

    Dim pos As Point = e.GetPosition(textbox1)
    textbox1.AppendText("X: " & pos.X.ToString() & " Y: " & pos.Y.ToString() & vbLf)

End Sub 'textbox1_StylusMove


Private Sub textbox1_StylusUp(ByVal sender As Object, ByVal e As StylusEventArgs) _
    Handles textbox1.StylusUp

    Stylus.Capture(textbox1, CaptureMode.None)

End Sub 'textbox1_StylusUp

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.
