如何在WPF中的菜单中设置输入手势文本的水平对齐方式？
How to set the Horizontal Alignment of the Input Gesture Texts in Menus in WPF?
我正在使用 WPF 制作一个应用程序并且有一个 Menu。在该菜单中，大多数项目都有键盘快捷键或输入手势。如何设置显示输入手势的文本的水平对齐方式？

为了改变输入手势文本的水平对齐方式，您必须适配MenuItem的控件模板。您可以从头开始创建它，也可以创建默认样式的副本 using Blend or Visual Studio. I recommend the latter. If you want to now more about the required parts and visual states of the MenuItem control, you can refer to the documentation.
在下文中，我提取了默认样式，并且仅提取了更改输入手势文本对齐方式实际需要的控件模板和资源。本质的变化是 menuGestureText TextBlock.
<TextBlock x:Name="menuGestureText" Grid.Column="4" Margin="{TemplateBinding Padding}" Opacity="0.7" Text="{TemplateBinding InputGestureText}" VerticalAlignment="Center" HorizontalAlignment="Right"/>
如您所见，我将 HorizontalAlignment 设置为 Right。这是必需的 XAML 标记：

<SolidColorBrush x:Key="Menu.Static.Border" Color="#FF999999"/>
<SolidColorBrush x:Key="Menu.Static.Foreground" Color="#FF212121"/>

您可以通过在 Menu 中将其引用为 ItemContainerStyle 来使用样式，或者将样式分配给 MenuItems。
<Menu ItemContainerStyle="{StaticResource MenuItemStyle}">
<MenuItem Header="File">
<MenuItem Header="New file" InputGestureText="Ctrl+N"/>
<MenuItem Header="New template" InputGestureText="Ctrl+Shift+N"/>
</MenuItem>
</Menu>
另一种选择是创建一种自动应用于范围内所有 MenuItem 的隐式样式。
<Style TargetType="{x:Type MenuItem}" BasedOn="{StaticResource MenuItemStyle}"/>
这是结果，输入手势文本右对齐。
