动画WindowsFormsHost

我需要为WindowsFormsHost控件设置动画。问题是我无法看到动画,窗口没有刷新。如果我在动画期间调整WPF窗口的大小,则可以看到转换。

我尝试将WindowsFormsHost放入网格中,然后为网格设置动画,但结果是一样的。我把一些其他东西放到网格中以确保我正确地编写了动画。

这是一个简单的应用程序,只是为了测试它:

<Window x:Class="WpfApplication1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"
    Title="MainWindow" Height="350" Width="525">

<Window.Resources>
    <Grid x:Key="MoveX">
        <Grid.RenderTransform>
            <TranslateTransform X="0"/>
        </Grid.RenderTransform>
    </Grid>

    <Storyboard x:Key="Story">
        <DoubleAnimation 
            Storyboard.Target="{StaticResource MoveX}"
            Storyboard.TargetProperty="RenderTransform.(TranslateTransform.X)"
            From="0"
            To="600"/>
    </Storyboard>
</Window.Resources>

<Grid>
    <Grid.RenderTransform>
        <TranslateTransform X="{Binding Source={StaticResource MoveX}, Path=RenderTransform.(TranslateTransform.X)}"/>
    </Grid.RenderTransform>

    <WindowsFormsHost Height="224" HorizontalAlignment="Left" Margin="26,24,0,0" Name="windowsFormsHost1" VerticalAlignment="Top" Width="404" Background="#FF762323">
        <wf:Panel BackColor="Green" Width="300" Height="200"/>
    </WindowsFormsHost>

    <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="328,269,0,0" Name="button1" VerticalAlignment="Top" Width="75" >
        <Button.Triggers>
            <EventTrigger RoutedEvent="Button.Click">
                <BeginStoryboard Storyboard="{StaticResource Story}"/>
            </EventTrigger>
        </Button.Triggers>
    </Button>
    <Label Content="Label" Height="28" HorizontalAlignment="Left" Margin="85,269,0,0" Name="label1" VerticalAlignment="Top" />
</Grid>
</Window>

有没有办法解决这个问题?

答案 0 :(得分:1)

混合使用WPF和WinForms或ActiveX内容时,这是一个众所周知的问题。在内部,每个渲染引擎都有自己的空域,像动画这样的互操作性是不可能的。

使用.net 4.5版本时,应解决此问题。
