Latex:数学之外的可拉伸花括号 [英] Latex: stretchable curly braces outside math

问题描述

我正在制作一些乳胶投影仪幻灯片(但我认为这本身不是投影仪特定的问题).

I am producing some latex beamer slides (but I think it is not a beamer specific question per se).

我有以下几点:

egin{itemize}
item Issue1
item Issue2
item Issue3
end{itemize}

现在，我想在散布在 issue1 和 issue2 上的项目后面有一个右花括号(即}").当然，我想在花括号后面写点什么.

Now, I want to have a right curly brace (i.e. '}') behind the items spreading over issue1 and issue2. And of course I want to write something behind that curly brace.

在一个完美的世界里，我会写这样的东西:

In a perfect world I would write something like:

egin{itemize}
left .
item Issue1
item Issue2

ight } One and Two are cool
item Issue3
end{itemize}

这不起作用，因为我不在数学环境中，我不能将整个代码段放入数学环境中，因为在这种情况下 itemize 不起作用.

This does not work because I am not in a math environment and I can not put the whole snippet inside a math environment because itemize would not work in that case.

是否有干净的解决方案或 hack 来产生我想要的结果?

Is there a clean solution or a hack to produce my desired result?

问候，巴斯蒂安.

推荐答案

我会使用 tikz 并进行叠加.

I'd use tikz and make an overlay.

首先包含正确的包(您可能不需要包含 tikz，因为这是一个投影问题):

First include the proper packages (you may not need to include tikz since this is a beamer question):

usepackage{tikz}
usetikzlibrary{decorations.pathreplacing}

然后，当您列出清单时，请在每个项目之后为地点命名:

Then when you make your list, give names to the places after each item:

egin{itemize}
    item Issue 1     
        	ikz[remember picture] 
ode[coordinate,yshift=0.5em] (n1) {}; 
    item Issue 2
        	ikz[remember picture] 
ode[coordinate] (n2) {};
    item Issue 3
end{itemize}

(注意:我将 y 值向上移动了 1/2 行，也许更多会更好.)

(Note: I shifted the y value up by 1/2 of a line maybe more would be better.)

因为我们使用了remember picture，所以我们可以在一个叠加层中引用这些地方:

Because we used remember picture we can refer to these places in an overlay:

  egin{tikzpicture}[overlay,remember picture]
      path (n2) -| node[coordinate] (n3) {} (n1);
      draw[thick,decorate,decoration={brace,amplitude=3pt}]
            (n1) -- (n3) node[midway, right=4pt] {One and two are cool};
  end{tikzpicture}

该路径用于处理宽度不同的项目.此编辑来自 ESultanik 的回答.

The path is there to deal with items that do not have the same width. This edit comes from ESultanik's answer.

结果是:

旁注:您可以删除所有 remember picture 选项并添加以下内容以自动将记住添加到所有图片:

Side note: You can remove all of the remember picture options and add the following to automatically add remember to all pictures:

	ikzstyle{every picture}+=[remember picture]
