问题描述

我在使用具有 IsCheckable=True 的 MenuItem 对象时遇到了一个奇怪的问题 - 一张截图值一千字:

这看起来很像

那么，我如何到达那个黑匣子，并让它成为，比如说，GhostWhite?

解决方案

为我工作.

按照您引用的链接中的说明导出模板.

将该样式应用到 MneuItems.

<按钮内容="一个"/><按钮内容="两个"/><菜单><MenuItem Header="Markets" Style="{DynamicResource MenuItemStyle1}"><MenuItem IsCheckable="True" Header="British" Style="{DynamicResource MenuItemStyle1}"/><MenuItem IsCheckable="True" Header="Irish" Style="{DynamicResource MenuItemStyle1}"/></菜单项></菜单></工具栏>

将模板中的 Background 更改为 Yellow 如下:

<Border x:Name="GlyphPanel" BorderBrush="#80DADADA" BorderThickness="1" Background="Yellow" Height="20" Margin="0,1" Visibility="Hidden" Width="20">

为了让这个例子完整，下面是我导出的模板:

I'm having a weird problem with MenuItem objects that have IsCheckable=True - a screenshot is worth a thousand words:

This looks very much like Check Mark Showing as a Black Box in Menu, except the accepted answer there, unless I misread it badly, suggests to tweak ToolBar.MenuStyleKey, which doesn't seem to be tweaking the right thing at all:

<Style x:Key="{x:Static ToolBar.MenuStyleKey}" TargetType="Menu">
    <Setter Property="Background" Value="Yellow" />
</Style>

So, how do I get to that black box, and make it, say, GhostWhite?

解决方案

Works for me.

Exported the template per the instructions in the link you referenced.

Applied that style to the MneuItems.

<ToolBar>
    <Button Content="One"/>
    <Button Content="Two"/>
    <Menu>
        <MenuItem Header="Markets" Style="{DynamicResource MenuItemStyle1}">
            <MenuItem IsCheckable="True" Header="British" Style="{DynamicResource MenuItemStyle1}"/>
            <MenuItem IsCheckable="True" Header="Irish" Style="{DynamicResource MenuItemStyle1}"/>
        </MenuItem>
    </Menu>
</ToolBar>

Changed Background to Yellow in the template as such:

<Border x:Name="GlyphPanel" BorderBrush="#80DADADA" BorderThickness="1" Background="Yellow" Height="20" Margin="0,1" Visibility="Hidden" Width="20">

Just to make this example totally complete, below is the template that I exported:

<Window.Resources>
    <Style x:Key="MenuItemStyle1" TargetType="{x:Type MenuItem}">
        <Setter Property="OverridesDefaultStyle" Value="True"/>
