我正在写（注销）样式ScrollBar。

问题是一个无法理解的空白空间，它等于标准宽度ScrollBar。如何删除它？

自己ScrollViewer：

<ScrollViewer Name="_scrollViewer" VerticalScrollBarVisibility="Visible">
    ...
</ScrollViewer>

    如果您查看标准样式ScrollBar，您可以在那里找到这一行：

    <Setter Property="MinWidth" Value="{DynamicResource {x:Static SystemParameters.VerticalScrollBarWidthKey}}"/>

    这个动态资源的背后是从操作系统设置中获取滚动条的宽度。

    整个问题在于它。只需覆盖MinWidth您的新样式。
