我的 WPF 应用程序在警车中运行，并具有夜间模式，可将应用程序切换到更柔和的颜色，这样屏幕就不会影响警官的夜视。我已经改变了几乎所有需要更改的颜色。问题是鼠标悬停在Tab控件和ComboBox控件上的背景颜色。这些变成明亮的蓝白色。

对于我的生活，我找不到这种颜色变化发生在哪里。这些控件的控件模板不包含我能找到Trigger的IsMouseOver属性。

有谁知道我在哪里可以找到这个设置？或者我应该IsMouseOver在我自己的基于 Aero 模板的自定义模板中添加一个触发器？

我使用 Visual Studio 2012 和 Windows 8，所以我的风格可能与你的略有不同。

那么当你将鼠标悬停在它上面时，是什么导致了蓝色呢？这个小多重触发器就在这里：

<MultiDataTrigger>
    <MultiDataTrigger.Conditions>
        <Condition Binding="{Binding IsMouseOver, RelativeSource={RelativeSource Self}}" Value="true"/>
        <Condition Binding="{Binding TabStripPlacement, RelativeSource={RelativeSource FindAncestor, AncestorLevel=1, AncestorType={x:Type TabControl}}}" Value="Top"/>
    </MultiDataTrigger.Conditions>
    <Setter Property="Background" TargetName="mainBorder">
        <Setter.Value>
            <LinearGradientBrush EndPoint="0,1" StartPoint="0,0">
                <GradientStop Color="#FFECF4FC" Offset="0"/>
                <GradientStop Color="#FFDCECFC" Offset="1"/>
            </LinearGradientBrush>
        </Setter.Value>
    </Setter>
    <Setter Property="BorderBrush" TargetName="mainBorder" Value="#FF7EB4EA"/>
    <Setter Property="BorderThickness" TargetName="innerBorder" Value="1,1,1,0"/>
    <Setter Property="BorderThickness" TargetName="mainBorder" Value="1,1,1,0"/>
</MultiDataTrigger>

从条件中可以看出，它在鼠标悬停时触发，并且标签条位于顶部。有一些其他触发器看起来相同，但是当标签在右侧，左下角。不过，那是你的颜色变化。

编辑：这是组合框的多重触发器：

<MultiDataTrigger>
    <MultiDataTrigger.Conditions>
        <Condition Binding="{Binding IsMouseOver, RelativeSource={RelativeSource Self}}" Value="true"/>
        <Condition Binding="{Binding IsEditable, RelativeSource={RelativeSource FindAncestor, AncestorLevel=1, AncestorType={x:Type ComboBox}}}" Value="false"/>
    </MultiDataTrigger.Conditions>
    <Setter Property="Background" TargetName="templateRoot">
        <Setter.Value>
            <LinearGradientBrush EndPoint="0,1" StartPoint="0,0">
                <GradientStop Color="#FFECF4FC" Offset="0"/>
                <GradientStop Color="#FFDCECFC" Offset="1"/>
            </LinearGradientBrush>
        </Setter.Value>
    </Setter>
    <Setter Property="BorderBrush" TargetName="templateRoot" Value="#FF7EB4EA"/>
</MultiDataTrigger>

可能是 SystemColors，您可以覆盖这些，不久前我在 Buttons 上遇到过类似问题（找不到项目 :()

要覆盖系统 burshes，您可以在您的<Window.Resources>或<ControlTemplate.Resources>

<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" />
<SolidColorBrush x:Key="{x:Static SystemColors.HotTrackBrushKey}" Color="Transparent" />

可以在此处找到要覆盖的 sustem 颜色的完整列表：http: //blogs.msdn.com/b/wpf/archive/2010/11/30/systemcolors-reference.aspx

就像我说的那样，我不确定这是否会有所帮助，但值得一试:)
