建構函式

ManipulationCompletedRoutedEventArgs()

初始化 ManipulationCompletedRoutedEventArgs 類別的新實例。

屬性

Container

取得被視為操作容器的 UIElement

Cumulative

取得操作開頭之後的整體變更。

Handled

取得或設定值,這個值會將路由事件標示為已處理。 將 設定為 true 可防止事件路由上的大部分處理常式再次處理相同的事件。

IsInertial

取得 ManipulationCompleted 事件是否發生在慣性期間。

OriginalSource

取得引發事件之 物件的參考。 這通常是控制項的範本部分,而不是在應用程式 UI 中宣告的專案。

(繼承來源 RoutedEventArgs)
PointerDeviceType

取得操作相關指標裝置的 PointerDeviceType

Position

取得位於完成位置之觸控輸入的 X 和 Y 螢幕座標。

Velocities

取得用於操作的速度。
