自定义窗口 chrome 设计时支持

Question

我有自己的自定义控件库项目，该库中的控件之一是类似窗口的 Zune 软件。在我的 WPF 应用程序中，我使用这个自定义窗口控件而不是默认窗口。当我运行我的应用程序时，一切都显示为它应该显示的内容，但问题是在设计时，在 Visual Studio 2012 中它仍然显示默认窗口。我希望能够在设计时拥有相同的 zune 软件风格。有什么方法，我怎样才能做到这一点？

通常我想要实现的目标类似于https://fluent.codeplex.com/，而不是从基类派生窗口，您所要做的就是以这种方式定义窗口

<Fluent:Ribbon>
<Fluent:RibbonTabItem Header="Home">
    <Fluent:RibbonGroupBox Header="Clipboard">
        <Fluent:SplitButton Text="Paste" Icon="Images\Paste.png" LargeIcon="Images\PasteLarge.png">
        ...
     </Fluent:RibbonGroupBox>
     <Fluent:RibbonGroupBox x:Name="Font" ....
</Fluent:RibbonTabItem>
...

你的意思是这样吗？

这是我自己的自定义代码，但如果您正在寻找更官方的来源，它可能类似于 http://archive.msdn.microsoft.com/WPFShell 库。

主窗口派生自现有窗口，或者在本例中为NavigationWindow

namespace Centivus.WPF
{
    [TemplatePartAttribute(Name = "PART_SearchTextBox", Type = typeof(TextBox))]
    public class SearchableNavigationWindow : NavigationWindow
    {
        ...

通过模板设置样式

<!-- Custom NavigationWindow UI -->
<Style x:Key="Win7NavigationWindow" TargetType="{x:Type local:SearchableNavigationWindow}">
    <Setter Property="MinWidth" Value="400"/>
    <Setter Property="glass:GlassEffect.IsEnabled" Value="True" />
    <Setter Property="glass:GlassEffect.Thickness">
        <Setter.Value>
            <Thickness Top="35"/>
        </Setter.Value>
    </Setter>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate>

                <DockPanel x:Name="mainDock"  LastChildFill="True" >
                    <!-- The border is used to compute the rendered height with margins.
                                topBar contents will be displayed on the extended glass frame.-->

唯一聪明的部分是使用附加属性来应用玻璃，如果您使用自定义镀铬，我会假设您正在做一些非常相似的事情
