wpf - 苹果风格的滚动条WPF

Question

我正在尝试减小滚动条控件的大小，使其更像“Apple”，因为它非常适合我的界面。

我想要实现的目标是这样的:

到目前为止我所拥有的就是这个

        <Style TargetType="{x:Type ScrollBar}">
            <Setter Property="Stylus.IsFlicksEnabled" Value="True" />
            <Setter Property="Background" Value="#8C8C8C" />
            <Setter Property="Width" Value="8"/>
            <Setter Property="MinWidth" Value="8" />
        </Style>

工作XAML

可以在 Apple Style Scrollbar in WPF 找到实现

    <!--Scrollbar Thumbs-->

它不是很漂亮，老实说，我不记得它来自哪里，有一些类似于你在我的一个项目中所追求的东西，可能有很多不需要的风格，或者不正确，但不妨尝试一下。

 <!--Scrollbar Thumbs-->
        <Style x:Key="ScrollThumbs" TargetType="{x:Type Thumb}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type Thumb}">
                        <Grid x:Name="Grid">
                            <Rectangle HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="Auto" Height="Auto" Fill="Transparent" />
                            <Border x:Name="Rectangle1" CornerRadius="10" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="Auto" Height="Auto"  Background="{TemplateBinding Background}" />
                        </Grid>
