我使用MahApps。地铁在设置指南中,它告诉您在App.xaml中包含一些代码。所以我这样做了。
现在,我希望能够添加我自己的样式到其中。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的时候如何设计风格。地铁,但有了它,我无法让两者都工作。
这里怎么了?
<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>
编辑
经过测试,我的第一个答案并不是很正确。您必须设置一个x:Key
,并在每个MetroWindow
xaml中使用此密钥。
<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>
使用
<Controls:MetroWindow x:Class="Demo"
Style="{DynamicResource CustomGlobalMetroWindow}" />
希望能有所帮助!
我最终是这样做的:
更少出错,更便于懒惰的
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);
}
}
