WPF RibbonWindow不显示Grip to resize窗口

Question

我有一个RibbonWindow,我的WindowStyle被设置为None,所以我无法理解的是Grip发生了什么调整窗口的大小？!即使我的控件的底部部分的边距设置为0也会被隐藏......这是一种奇怪的行为.

但是如果我改变控件的底部边距就可以了,但无论如何都看不到Grip,可能是因为部分客户区隐藏了......

我不得不说,如果有一个WPF窗口,这不会发生,它只发生在RibbonWindow上.我正在使用RibbonWindow,因为Ribbon在适当的窗口中具有其他外观.

那么我该怎么做才能解决Grip的问题呢？

我的一些代码......

<rib:RibbonWindow x:Class="MyApp.Views.MainView"
                  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                  xmlns:rib="clr-namespace:Microsoft.Windows.Controls.Ribbon;assembly=RibbonControlsLibrary"
                  AllowsTransparency="True"
                  Background="Transparent"
                  Height="750"
                  ResizeMode="CanResizeWithGrip"
                  Width="1000"
                  WindowStartupLocation="CenterScreen"
                  WindowStyle="None">

    <Grid Margin="0, 0, 0, 20">
        <Border Background="Black"
                CornerRadius="5"
                Opacity="0.5"/>
    </Grid>
</rib:RibbonWindow>

提前致谢!

这对调试很有吸引力.事实证明,窗口的样式有一个错误:如果系统被定义为IsGlassEnabled == true(在Win7 Aero主题中使用它true),那么窗口依赖于Microsoft.Windows.Shell.WindowChrome(从Microsoft.Windows.Shell程序集)到绘制窗口的边框和顶部按钮; 并且此WindowChrome的GlassFrameThickness属性设置为8,30,8,8与NonClientFrameEdgesset to 组合Bottom.

会发生的是,由于AllowsTransparency == true玻璃边框是透明的,但窗口仍然从整个窗口大小"切割"其厚度,因为WindowChrome定义NonClientFrameEdges="Bottom",从而切断了ResizeGrip视图.

如果您(疯狂地)将窗口拖到屏幕上,您可以看到这一点 - 您将看到ResizeGrip闪烁.

为了解决这个问题,我们需要定义一个新的WindowChrome有NonClientFrameEdges="None"(或GlassFrameThickness = 0或两者),并将其分配到窗口,只有当IsGlassEnabled == true && AllowsTransparency == true(我使用App.xaml中定义的应用程序资源,仅定义NonClientFrameEdges="None"):

1. Add these namespaces to App.xaml:
    xmlns:ribbon="clr-namespace:Microsoft.Windows.Controls.Ribbon;assembly=RibbonControlsLibrary"
    xmlns:ribbonPrimitives="clr-namespace:Microsoft.Windows.Controls.Ribbon.Primitives;assembly=RibbonControlsLibrary"
    xmlns:shell="clr-namespace:Microsoft.Windows.Shell;assembly=Microsoft.Windows.Shell"

2. Add these resources:
    <ribbonPrimitives:RibbonWindowSmallIconConverter x:Key="RibbonWindowSmallIconConverter" />
    <shell:WindowChrome x:Key="WindowChromeWithGlassAndTransparency"
                        NonClientFrameEdges="None" />
    <Style x:Key="MyStyle"
           TargetType="{x:Type ribbon:RibbonWindow}">
        <Style.Triggers>
            <MultiDataTrigger>
                <MultiDataTrigger.Conditions>
                    <Condition Binding="{Binding Path=IsGlassEnabled, Source={x:Static shell:SystemParameters2.Current}}"
                               Value="True" />
                    <Condition Binding="{Binding AllowsTransparency, RelativeSource={RelativeSource Mode=Self}}"
                               Value="False" />
                </MultiDataTrigger.Conditions>
                <Setter Property="shell:WindowChrome.WindowChrome"
                        Value="{DynamicResource {ComponentResourceKey TypeInTargetAssembly={x:Type ribbon:Ribbon}, ResourceId=WindowChromeAeroWithGlass}}" />

            <MultiDataTrigger>

                    <Condition Binding="{Binding AllowsTransparency, RelativeSource={RelativeSource Mode=Self}}"

                </Setter>
            </DataTrigger>
        </Style.Triggers>
    </Style>

3. In your window use the new style:
    <rib:RibbonWindow ....
                      Style="{StaticResource MyStyle}">

        ....
    </rib:RibbonWindow>

在DataTrigger几乎是从原有的风格,只有一个修改:我评论了WindowChrome的制定者.

这MultiDataTrigger是我的补充.他们检查AllowsTransparency属性的值并应用正确的WindowChrome:如果值为,则为原始值;如果值为,则false应用NonClientFrameEdges="None"(还可以使用GlassFrameThickness = 0)true.

注意:此解决方案删除了​​使用边缘调整窗口大小的功能,窗口的大小调整仅由ResizeGrip.
