[英]In WPF, how do I right justify menu items while keeping keyboard shortcuts?
I recently changed my XAML in order to gain the capability to right-justify menu items such as setting font sizes in the below graphic: 我最近更改了我的XAML,以获得右对齐菜单项的功能,例如在下图中设置字体大小:
File Configure Help +-------------+ +----+ | Font size > |->| 8 | | Speed > | | 10 | +-------------+ | 12 | +----+
Obviously, based on that graphic, I won't be moving from a technical role into graphic design anytime soon :-) It's more just to illustrate what I meant. 显然,基于该图形,我不会很快从技术角色转变为平面设计:-)更多只是为了说明我的意思。
The original XAML below did not right-justify the values 下面的原始XAML没有对这些值进行右对齐
<MenuItem Header="_Configure">
<MenuItem Header="_Font size ">
<MenuItem Header="_8" Click="menuConfigFontSz8" />
<MenuItem Header="1_0" Click="menuConfigFontSz10" />
<MenuItem Header="1_2" Click="menuConfigFontSz12" />
</MenuItem>
:
</MenuItem>
Instead, it gave me: 相反,它给了我:
File Configure Help +-------------+ +----+ | Font size > |->| 8 | | Speed > | | 10 | +-------------+ | 12 | +----+
So, to get right-justification, I changed it to: 因此,为了获得正确的理由,我将其更改为:
<MenuItem Header="_Configure">
<MenuItem Header="_Font size ">
<MenuItem Click="menuConfigFontSz8">
<MenuItem.Header>
<TextBlock HorizontalAlignment="Right">_8</TextBlock>
</MenuItem.Header>
</MenuItem>
<MenuItem Click="menuConfigFontSz10">
<MenuItem.Header>
<TextBlock HorizontalAlignment="Right">1_0</TextBlock>
</MenuItem.Header>
</MenuItem>
<MenuItem Click="menuConfigFontSz12">
<MenuItem.Header>
<TextBlock HorizontalAlignment="Right">1_2</TextBlock>
</MenuItem.Header>
</MenuItem>
</MenuItem>
:
</MenuItem>
However, I find I've lost the shortcut capability of doing Alt C , F , 0 for selecting font size 10 (it's just the 0
bit that no longer works, the first two bits are still fine). 但是,我发现我已经失去了使用Alt C , F , 0来选择字体大小10的快捷功能(它只是0
位不再有效,前两位仍然很好)。
Instead it gives me the literal text 1_0
in the menu itself rather than allowing me to use 0
as a quick way of selecting the item: 相反,它给了我菜单本身的文字文本1_0
,而不是允许我使用0
作为选择项目的快捷方式:
File Configure Help +-------------+ +-----+ | Font size > |->| _8 | | Speed > | | 1_0 | +-------------+ | 1_2 | +-----+
How do I keep the right justification of the menu text but still allow for an accelerator? 如何保持菜单文本的正确理由,但仍允许使用加速器?
When you add an accelerator to a MenuItem (and Button) WPF automatically adds a TextBlock to your MenuItem, and this probably prevents your code from working. 当您向MenuItem(和Button)添加加速器时,WPF会自动将TextBlock添加到您的MenuItem,这可能会阻止您的代码工作。 You can see this effect if you take a look at the answer to this question . 如果你看看这个问题的答案 ,你可以看到这种效果。
This code solves the problem if you do not have a generic TextBlock style in your resources that overrides the default TextBlock behaviour. 如果您的资源中没有覆盖默认TextBlock行为的通用TextBlock样式,则此代码可以解决此问题。
<MenuItem Header="_Configure">
<MenuItem Header="_Font size">
<MenuItem Click="menuConfigFontSz8" Header="_8" HorizontalAlignment="Right"/>
<MenuItem Click="menuConfigFontSz10" Header="1_0" HorizontalAlignment="Right"/>
<MenuItem Click="menuConfigFontSz12" Header="1_2" HorizontalAlignment="Right"/>
</MenuItem>
