WPF自定义控件字体属性

Question

我有两个自定义控件，一个自ContentPresenter派生，另一个自StackPanel派生，它们都不具有字体属性。现在，我发现我需要为它们实现字体属性。我曾尝试实现FrontFamily，FontWeigh和FontSize作为依赖项属性，但是它们没有出现在设计器中。有没有人和如何在自定义控件中实现字体的示例？

我的代码当前为：

    [ Category( "Text" ) ]
    public FontFamily FontFamily
    {
        get => (FontFamily)GetValue( FontFamilyProperty );
        set => SetValue( FontFamilyProperty, value );
    }

    // Using a DependencyProperty as the backing store for FontFamily.  This enables animation, styling, binding, etc...
    public static readonly DependencyProperty FontFamilyProperty =
        TextElement.FontFamilyProperty.AddOwner( typeof( MyControl ), new FrameworkPropertyMetadata( SystemFonts.MessageFontFamily, FrameworkPropertyMetadataOptions.Inherits ) );

    [ Category( "Text" ) ]
    [ TypeConverter( typeof( FontSizeConverter ) ) ]
    public double FontSize
    {
        get => (double)GetValue( FontSizeProperty );
        set => SetValue( FontSizeProperty, value );
    }

    // Using a DependencyProperty as the backing store for FontSize.  This enables animation, styling, binding, etc...
    public static readonly DependencyProperty FontSizeProperty =
        TextElement.FontSizeProperty.AddOwner( typeof( MyControl ), new FrameworkPropertyMetadata( SystemFonts.MessageFontSize, FrameworkPropertyMetadataOptions.Inherits ) );

    [ Category( "Text" ) ]
    public FontStretch FontStretch
    {
        get => (FontStretch)GetValue( FontStretchProperty );
        set => SetValue( FontStretchProperty, value );
    }

    // Using a DependencyProperty as the backing store for FontStretch.  This enables animation, styling, binding, etc...
    public static readonly DependencyProperty FontStretchProperty =
        TextElement.FontStretchProperty.AddOwner( typeof( MyControl ), new FrameworkPropertyMetadata( TextElement.FontStretchProperty.DefaultMetadata.DefaultValue, FrameworkPropertyMetadataOptions.Inherits ) );

    [ Category( "Text" ) ]
    public FontStyle FontStyle
    {
        get => (FontStyle)GetValue( FontStyleProperty );
        set => SetValue( FontStyleProperty, value );
    }

    // Using a DependencyProperty as the backing store for FontStyle.  This enables animation, styling, binding, etc...
    public static readonly DependencyProperty FontStyleProperty = TextElement.FontStyleProperty.AddOwner( typeof( MyControl ), new FrameworkPropertyMetadata( SystemFonts.MessageFontStyle, FrameworkPropertyMetadataOptions.Inherits ) );

    [ Category( "Text" ) ]
    public FontWeight FontWeight
    {
        get => (FontWeight)GetValue( FontWeightProperty );
        set => SetValue( FontWeightProperty, value );
    }

    // Using a DependencyProperty as the backing store for FontWeight.  This enables animation, styling, binding, etc...
    public static readonly DependencyProperty FontWeightProperty = TextElement.FontWeightProperty.AddOwner( typeof( MyControl ), new FrameworkPropertyMetadata( SystemFonts.MessageFontWeight, FrameworkPropertyMetadataOptions.Inherits ) );
