c# - 添加自定义样式到 Mahapps.Metro 现有的

Question

我使用 MahApps.Metro .在设置指南中，它告诉您将一些代码包含到 App.xaml 中。所以我做到了。

现在我希望能够向其中添加我自己的样式。例如，这包括默认情况下具有边框的所有窗口。

但这行不通。不应用边框。我知道在不使用 MahApps.Metro 时如何设置样式，但有了它，我无法同时工作。

这里有什么问题吗？

<Application x:Class="ProjectName.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="Windows/MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
                <!-- This is what I added -->
                <ResourceDictionary xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro">
                    <Style TargetType="Controls:MetroWindow">
                        <Setter Property="BorderThickness" Value="1" />
                        <Setter Property="BorderBrush" Value="{DynamicResource AccentColorBrush}" />
                    </Style>
                </ResourceDictionary>
                <!-------------------------->
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

您忘记了使用 BasedOn 继承样式:

<ResourceDictionary xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro">
    <Style TargetType="Controls:MetroWindow"
           BasedOn="{StaticResource {x:Type Controls:MetroWindow}}">
        <Setter Property="BorderThickness" Value="1" />
        <Setter Property="BorderBrush" Value="{DynamicResource AccentColorBrush}" />
    </Style>
</ResourceDictionary>

经过测试，我的第一个答案并不正确。您必须设置一个 x:Key 并在每个 MetroWindow xaml 中使用此键。

<Style x:Key="CustomGlobalMetroWindow"
        TargetType="{x:Type Controls:MetroWindow}"
        BasedOn="{StaticResource {x:Type Controls:MetroWindow}}">
    <Setter Property="BorderThickness"
            Value="1" />
    <Setter Property="BorderBrush"
            Value="Purple" />
</Style>

用法

<Controls:MetroWindow x:Class="Demo"
                      Style="{DynamicResource CustomGlobalMetroWindow}" />

希望对您有所帮助!
