## About
Theme manager for [Avalonia](https://github.com/AvaloniaUI/Avalonia) applications.
## Usage
Theme manager searches user provided themes directory for `*.xaml` theme files otherwise built-in `Light` and `Dark` theme are used.
The `ThemeSelector` is created and initalized by calling static `Create` method.
The `ThemeSelector` uses `Styles[0]` property of `Window` to insert selected theme `Style`.
`App.xaml`
```XAML
```
`App.xaml.cs`
```C#
using System;
using Avalonia;
using Avalonia.Logging.Serilog;
using Avalonia.Markup.Xaml;
using Avalonia.ThemeManager;
namespace AvaloniaApp
{
public class App : Application
{
public static ThemeSelector Selector;
[STAThread]
static void Main(string[] args)
{
BuildAvaloniaApp().Start(AppMain, args);
}
static void AppMain(Application app, string[] args)
{
Selector = ThemeSelector.Create("Themes");
Selector.LoadSelectedTheme("AvaloniaApp.theme");
app.Run(new MainWindow());
Selector.SaveSelectedTheme("AvaloniaApp.theme");
}
public static AppBuilder BuildAvaloniaApp()
=> AppBuilder.Configure()
.UsePlatformDetect()
.UseReactiveUI()
.LogToDebug();
public override void Initialize()
{
AvaloniaXamlLoader.Load(this);
}
}
}
```
`MainWindow.xaml`
```XAML
<Setter Property="Header" Value="{Binding Name}"/>
<Setter Property="Command" Value="{Binding Selector.ApplyTheme}"/>
<Setter Property="CommandParameter" Value="{Binding}"/>
<Setter Property="Icon">
<Template>
<CheckBox>
<CheckBox.IsChecked>
<MultiBinding Mode="OneWay" Converter="{StaticResource ObjectEqualityMultiConverter}">
<Binding Path="DataContext" RelativeSource="{RelativeSource Self}"/>
<Binding Path="Selector.SelectedTheme"/>
</MultiBinding>
</CheckBox.IsChecked>
</CheckBox>
</Template>
</Setter>
```
`MainWindow.xaml.xs`
```C#
using Avalonia;
using Avalonia.Controls;
using Avalonia.Markup.Xaml;
using Avalonia.ThemeManager;
namespace AvaloniaApp
{
public partial class MainWindow : Window
{
public MainWindow()
{
this.InitializeComponent();
this.AttachDevTools();
App.Selector.EnableThemes(this);
}
private void InitializeComponent()
{
AvaloniaXamlLoader.Load(this);
}
}
}
```
The `EnableThemes(...);` can be used to enable themes for multiple windows.
