将自定义样式添加到 Mahapps.Metro 个现有样式

Question

我用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，这包括所有 windows 默认情况下有边框。

但这不起作用。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。

这是怎么回事？

<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>

Answer 1

您忘记继承样式 BasedOn:

<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！

我最后是这样做的：

不易出错，对懒惰更友好

public partial class App : Application
{
    protected override void OnStartup(StartupEventArgs e)
    {
        ThemeManager.ChangeAppStyle(this,
                                    ThemeManager.GetAccent("Amber"),
                                    ThemeManager.GetAppTheme("BaseDark"));

        var allTypes = typeof(App).Assembly.GetTypes();
        var filteredTypes = allTypes.Where(d =>
            typeof(MetroWindow).IsAssignableFrom(d)
            && typeof(MetroWindow) != d
            && !d.IsAbstract).ToList();

        foreach (var type in filteredTypes)
        {
            var defaultStyle = this.Resources["MetroWindowDefault"];
            this.Resources.Add(type, defaultStyle);
        }

        base.OnStartup(e);
    }
}
