WP8 WebBrowser作為全景圖/透視圖項

Question

我添加了一個WebBrowser作為全景項目之一的內容。 WebBrowser呈現沒有問題。 如果我通過觸摸Web瀏覽器外部的區域來滑動全景，則會發生滑動。 但是，當我嘗試通過觸摸WebBrowser滑動全景時，不會發生滑動，而是WebBrowser垂直滾動。 知道如何解決這個問題？

我沒有投票，但是可能是因為這是一個壞主意。 通過設計，這些項目不應合並。 但是，如果您真的想讓瀏覽器始終處於旋轉狀態，則可以在此處瀏覽一下

盡管您無疑會發現UI指南不建議這樣做，但是這對我來說是必要的要求，我可以通過直接訂閱Touch事件並手動檢測滑動來解決此問題：

    // controls "swipe" behavior
    private Point touchDownPosition;  // last position of touch down
    private int touchDownTime;        // last time of touch down
    private int touchUpTime;          // last time of touch up
    private int swipeMaxTime = 1000;  // time (in milliseconds) that a swipe must occur in
    private int swipeMinDistance = 25;// distance (in pixels) that a swipe must cover
    private int swipeMinBounceTime = 500; // time (in milliseconds) between multiple touch events (minimizes "bounce")

    // handler for touch events
    void Touch_FrameReported(object sender, TouchFrameEventArgs e) 
    {
        var item = MyPivot.SelectedItem as PivotItem;

        // ignore touch if we are not on the browser pivot item
        if (item != BrowserPivotItem) 
            return;

        var point = e.GetPrimaryTouchPoint(item);
        switch (point.Action) 
        {
            case TouchAction.Down:
                touchDownTime = e.Timestamp;
                touchDownPosition = point.Position;
                touchUpTime = 0;
                break;

            case TouchAction.Up:
                // often multiple touch up events are fired, ignore re-fired events
                if (touchUpTime != 0 && touchUpTime - e.Timestamp < swipeMinBounceTime)
                    return;

                touchUpTime = e.Timestamp;
                var xDelta = point.Position.X - touchDownPosition.X;
                var yDelta = point.Position.Y - touchDownPosition.Y;
                // ensure touch event meets the requirements for a "swipe"
                if (touchUpTime - touchDownTime < swipeMaxTime && Math.Abs(xDelta) > swipeMinDistance && Math.Abs(xDelta) > Math.Abs(yDelta)) 
                {
                    // advance to next pivot item depending on swipe direction
                    var iNext = MyPivot.SelectedIndex + (delta > 0 ? -1 : 1);
                    iNext = iNext < 0 || iNext == MyPivot.Items.Count ? 0 : iNext;
                    MyPivot.SelectedIndex = iNext;
                }
                break;
        }
    }

然后，在需要的地方訂閱Touch.FrameReported，或者為了更好的優化，僅在選擇包含瀏覽器的樞軸項目時訂閱事件處理程序：

    private void MyPivot_OnSelectionChanged(object sender, SelectionChangedEventArgs e) 
    {
        if ((sender as Pivot).SelectedItem == BrowserPivotItem) 
          Touch.FrameReported += Touch_FrameReported;
        else 
          Touch.FrameReported -= Touch_FrameReported;
    }
