WPF触摸事件+闪烁

Question

我正在实现MVVM项目中描述的解决方案:http://nui.joshland.org/2010/04/why-wont-wpf-controls-work-with-touch.html

但问题是，如果我实现的TouchDown和TouchUp事件处理程序在UserControl在我的XAML然后我遇到了一个问题，其他GroupView不能得到的窗口消息为轻弹-或轻弹不能被处理，所以他们的相关窗口消息永远不会发送。

视图的自顶向下结构为:ButtonsView——有Touch事件处理程序GroupView——有鼠标事件处理程序和Flicks事件处理程序

我在代码后面使用这个来挂钩flick并处理它们:

    private void UserControl_Loaded(object sender, RoutedEventArgs e)
    {
        HwndSource source = PresentationSource.FromVisual(this) as HwndSource;
        source.AddHook(WndProc);
    }
    private IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
    {
        if (msg == Flicks.WM_TABLET_FLICK)
        {
            Flick flick = Flicks.ProcessMessage(lParam, wParam);
            if (flick != null)
            {
                if (flick.Data.Direction == FLICKDIRECTION.FLICKDIRECTION_LEFT)
                    Scroller("left"); //scrolls left
                else if (flick.Data.Direction == FLICKDIRECTION.FLICKDIRECTION_RIGHT)
                    Scroller("right"); //scrolls right
                else if (flick.Data.Direction == FLICKDIRECTION.FLICKDIRECTION_UP)
                    Scroller("up"); //move up
                else if (flick.Data.Direction == FLICKDIRECTION.FLICKDIRECTION_DOWN)
                    Scroller("down"); //move down
                    handled = true;
            }
        }
        return IntPtr.Zero;
    }

想法/建议吗?我对WPF很陌生。由于

我通过在ButtonsView中捕获鼠标事件和轻弹事件来解决这个问题，这样它们就不会隧道到GroupView
