備註

每當滑鼠雙擊或用手指或筆快速連續點擊該物件兩次時，就會觸發 雙重點擊 事件。

建構函式

名稱	Description
DoubleTappedRoutedEventArgs()	初始化 DoubleTappedRoutedEventArgs 類別的新實例。

屬性

名稱	Description
Handled	取得或設定一個值，標記路由事件為已處理。 值 trueHandled 可防止大多數事件路徑上的處理器再次處理同一事件。
OriginalSource	會得到一個指向引發事件的物件的參考。 這通常是控制項中的範本部分，而非你應用程式介面中聲明的元素。 (繼承來源 RoutedEventArgs)
PointerDeviceType	取得發起相關輸入事件的指標裝置的 PointerDeviceType 。

方法

名稱	Description
GetPosition(UIElement)	回傳指標位置的 x 與 y 座標，可選擇性地以所提供 UIElement 的座標原點評估。
