WPF - 如何设置菜单控件的样式以删除左边距？

转载作者：行者123 更新时间：2023-12-02 09:29:17

我已将默认菜单控件添加到我的用户控件中。我需要设置菜单样式以删除包含图标或复选框空间的左边距。我怎样才能做到这一点？

XAML:

<Menu>
    <MenuItem Header="MyMenu" FontSize="10">
        <MenuItem Header="Options..." />
        <MenuItem Header="About" />
    </MenuItem>
</Menu>

它目前的呈现方式与开箱即用的任何其他菜单控件一样:

alt text

我不希望菜单项左侧有边距或列。这通常用于图标等。

我认为这就是你所追求的(再次，使用Expression Blend来解决它，但就它显示的内容而言，它是我能得到的最简约的......并且花了很多时间来玩弄) ...您可以将以下内容放入空白 WPF 应用程序中作为示例:
