About this project

This project enables you to theme your WPF Application.

How to use the ThemeManager

First, you need to initialize the ThemeManager.

  public partial class App : Application
    {
        protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);
            /// Initialize the theme Skeumorph Dark Theme
            var a = SkeumorphDarkTheme.CreateSkeumorphNightTheme(null, null, null,
                new[] { "SkeuTest1", "SkeuTest2" },
                new Uri("pack://application:,,,/LazyApiPack.Wpf.Theme.UITest;component/Themes/CustomSkeumorphTheme.xaml", UriKind.Absolute));

            /// Initialize the theme Skeumorop Bright Theme
            var b = SkeumorphBrightTheme.CreateSkeumorphBrightBlueTheme(null, null, null,
                  new[] { "SkeuTest3", "SkeuTest4" },
                  new Uri("pack://application:,,,/LazyApiPack.Wpf.Theme.UITest;component/Themes/CustomSkeumorphTheme.xaml", UriKind.Absolute));
            /// Initialize the theme Skeumorph Bright THEME
            var c = SkeumorphBrightTheme.CreateSkeumorphBrightGreenTheme(null, null, null,
                      new[] { "SkeuTest5", "SkeuTest6" },
                      new Uri("pack://application:,,,/LazyApiPack.Wpf.Theme.UITest;component/Themes/CustomSkeumorphTheme.xaml", UriKind.Absolute));
            /// Set theme a as the current theme.
            ThemeService.CurrentTheme = a;
        }
    }

How to switch a theme

You can set the theme in code with

ThemeService.CurrentTheme = themeObject;

or you can bind the Theme Manager in the UI

<ComboBox 
    SelectedItem="{Binding CurrentTheme, Source={x:Static local:App.ThemeService}}" 
    ItemsSource="{Binding AvailableThemes, Source={x:Static local:App.ThemeService}}" />

It might be easier to use the theme manager in an MVVM application and instantiate the theme service as a singleton service.

How to add predefined themes

To add predefined themes, simply install a packed from the LazyApiPack.Wpf.Theme.* namespace and use the Theme-Classes eg:

var theme = SkeumorphDarkTheme.CreateSkeumorphNightTheme("Title to override", "Description to override", 
    new BitmapImage(/*Screenshot for the user*/),
    new[] { "Search Tag", "Another Search Tag" },
    new Uri("Additional Resource", UriKind.Absolute));

How to include custom control themes to a theme

To add custom themes to a theme, simply call the Create*Theme function or the Theme constructor with additional resources

SkeumorphDarkTheme.CreateSkeumorphNightTheme("Title to override", "Description to override", 
    new BitmapImage(/*Screenshot for the user*/),
    new[] { "Search Tag", "Another Search Tag" },
    // This line adds the CustomSkeumorphTheme to this theme.
    new Uri("pack://application:,,,/LazyApiPack.Wpf.Theme.UITest;component/Themes/CustomSkeumorphTheme.xaml", UriKind.Absolute));

the XAML of CustomSkeumorphTheme could look like this;

<ControlTemplate x:Key="SpecialControlTemplate" TargetType="{x:Type local:SpecialControl}" >
    <Border BorderBrush="{DynamicResource PrimaryForegroundColorBrush}" Background="{DynamicResource PrimaryBackgroundColorBrush}" BorderThickness="5">
        <Grid>
            <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="{TemplateBinding Title}"/>
        </Grid>
    </Border>
</ControlTemplate>

<Style TargetType="{x:Type local:SpecialControl}">
    <Setter Property="Template" Value="{StaticResource SpecialControlTemplate}"/>
</Style>

Ensure you have a Generic.xaml in your project with the default theme and it is mapped to the Application.Resources.MergedResourceDictionaries
