範例

下列程式碼範例顯示 輸入範例中的案例 4。 此程式碼示範使用 ManipulationStarting、 ManipulationStarted、 ManipulationDelta、 ManipulationInertiaStarting和 ManipulationCompleted 事件直接操作的一些使用模式。

}

private void ManipulateMe_ManipulationDelta(
    object sender, ManipulationDeltaRoutedEventArgs e)
{
    if (forceManipulationsToEnd)

        return;
    }

        _compositeTransform.ScaleY = e.Delta.Scale;
    _compositeTransform.TranslateX = e.Delta.Translation.X;
    _compositeTransform.TranslateY = e.Delta.Translation.Y;

    e.Handled = true;
}

private void ManipulateMe_ManipulationCompleted(object sender, 
    ManipulationCompletedRoutedEventArgs e)
{
    e.Handled = true;
}

private void Scenario4Reset(object sender, RoutedEventArgs e)
{
    Scenario4Reset();
}

void Scenario4Reset()

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。 設定 以防止 true 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。
