我正在创建基于Awesonium的多点触控浏览器。为此,我使用 Awesomium Web Control 和一些其他控件创建了新的用户控件。我已设置此属性:IsManipulationEnabled="True" 关于这篇文章with is here,我已经超越了这个功能:

protected override void OnManipulationDelta(ManipulationDeltaEventArgs e)
{
    UIElement element = e.Source as UIElement;
    MatrixTransform xform =
        element.RenderTransform as MatrixTransform;
    Matrix matrix = xform.Matrix;
    ManipulationDelta delta = e.DeltaManipulation;
    Point center = e.ManipulationOrigin;
    matrix.ScaleAt(
        delta.Scale.X, delta.Scale.Y, center.X, center.Y);
    matrix.RotateAt(
        delta.Rotation, center.X, center.Y);
    matrix.Translate(
        delta.Translation.X, delta.Translation.Y);
    xform.Matrix = matrix;
    e.Handled = true;
    base.OnManipulationDelta(e);
}

但是操作对Ui元素不起作用。用户控件的XAML代码:

<UserControl
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         xmlns:awe="http://schemas.awesomium.com/winfx" x:Class="WebControlTouch.WebBrowser" 
         mc:Ignorable="d" 
         d:DesignHeight="600" d:DesignWidth="800">
<Grid>

    <awe:WebControl HorizontalAlignment="Left" Margin="0,58,0,0" VerticalAlignment="Top" Width="790" Name="_browser" AddressChanged="_browser_AddressChanged"/>
    <TextBox HorizontalAlignment="Left" Name="_addressBar" Height="43" Margin="0,10,0,0" TextWrapping="Wrap" Text="Address" VerticalAlignment="Top" Width="335"/>
    <Button Content="Go!" HorizontalAlignment="Left" Margin="340,10,0,0" VerticalAlignment="Top" Width="133" RenderTransformOrigin="-0.164,0.514" Height="43" Click="Button_Click"/>

</Grid>

我应该怎样做才能让操作起作用?

我不知道你是否解决了这个问题,但在你的UserControl中你没有设置下面的代码
  IsManipulationEnabled="True"

我不知道您在何处设置此属性,但您需要在UserControl标记中设置它
