XAML 如何制作定制的ListBox

我需要在wpf xaml中自定义我的列表框。下面是它应该是什么样子：

如你所见，我标出了关键点。
要点1：滚动条应该比正常情况下更细。例如，其宽度设置为6
点2：滚动条和列表框主体之间差距，例如第五组。
我知道一种方法是修改复制的ListBox模板，如下所示：但我不知道我提到的这两点对应的是哪一个。

<Window.Resources>
    <SolidColorBrush x:Key="ListBox.Static.Background" Color="#FFFFFFFF"/>
    <SolidColorBrush x:Key="ListBox.Static.Border" Color="#FFABADB3"/>
    <SolidColorBrush x:Key="ListBox.Disabled.Background" Color="#FFFFFFFF"/>
    <SolidColorBrush x:Key="ListBox.Disabled.Border" Color="#FFD9D9D9"/>
    <Style x:Key="ListBoxStyle1" TargetType="{x:Type ListBox}">
        <Setter Property="Background" Value="{StaticResource ListBox.Static.Background}"/>
        <Setter Property="BorderBrush" Value="{StaticResource ListBox.Static.Border}"/>
        <Setter Property="BorderThickness" Value="1"/>
        <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
        <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Auto"/>
        <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto"/>
        <Setter Property="ScrollViewer.CanContentScroll" Value="true"/>
        <Setter Property="ScrollViewer.PanningMode" Value="Both"/>
        <Setter Property="Stylus.IsFlicksEnabled" Value="False"/>
        <Setter Property="VerticalContentAlignment" Value="Center"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ListBox}">
                    <Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="1" SnapsToDevicePixels="true">
                        <ScrollViewer Focusable="false" Padding="{TemplateBinding Padding}">
                            <ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
                        </ScrollViewer>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsEnabled" Value="false">
                            <Setter Property="Background" TargetName="Bd" Value="{StaticResource ListBox.Disabled.Background}"/>
                            <Setter Property="BorderBrush" TargetName="Bd" Value="{StaticResource ListBox.Disabled.Border}"/>
                        </Trigger>
                        <MultiTrigger>
                            <MultiTrigger.Conditions>
                                <Condition Property="IsGrouping" Value="true"/>
                                <Condition Property="VirtualizingPanel.IsVirtualizingWhenGrouping" Value="false"/>
                            </MultiTrigger.Conditions>
                            <Setter Property="ScrollViewer.CanContentScroll" Value="false"/>
                        </MultiTrigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>

您必须覆盖ScrollBar的默认模板。然后你可以将它设置为ScrollBar的隐式样式（我没有修改所有的地方，但你肯定能找到合适的地方，我也在那里设置了一些注解）。

<Color x:Key="ControlMouseOverColor">#FF3843C4</Color>
<Color x:Key="ControlPressedColor">#FF211AA9</Color>
<Color x:Key="DisabledForegroundColor">#FF888888</Color>
                
<Style x:Key="ScrollBarLineButton" TargetType="{x:Type RepeatButton}">
    <Setter Property="SnapsToDevicePixels" Value="True" />
    <Setter Property="OverridesDefaultStyle" Value="true" />
    <Setter Property="Focusable" Value="false" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type RepeatButton}">
                <Border x:Name="Border" Margin="1" CornerRadius="2" BorderThickness="1">
                    <Border.BorderBrush>
