如何将 tikz 框与分项项目符号对齐？

Question

我有以下代码产生以下结果

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes.misc}
\usepackage{enumitem}
\newcommand{\hour}[1]{\tikz{
  \node[draw, rounded corners=1mm,text depth=0.8ex,line width=1pt] (a) {\Large{}#1}}}

\begin{document}
  \begin{itemize}[label=$\bullet$]
    \item \hour{Hour}
\end{itemize}
\end{document}

我想：

• 将文本置于框内中央
• 将框的中心与项目符号对齐

我怎样才能实现这个目标？

Answer 1

我会这么做：

1. 使用节点 (a) 设置基线。这样，您将获得与正常大小文本正确的对齐方式。如果您希望大文本有更好的对齐方式，您也可以更改项目符号的大小。
2. \strut在节点中放置（或不放置）。使用 时\strut，所有框的高度都相同。不使用 时，文本将垂直居中。

\documentclass{article}
\usepackage   {enumitem}
\usepackage   {tikz}

\newcommand{\firsthour}[1]{%
  \tikz[baseline=(a.base)]
    \node[draw,rounded corners=1mm,line width=1pt,inner sep=0.3ex] (a) {\Large\strut#1};% <-- We don't want a space here
}

\newcommand{\secondhour}[1]{%
  \tikz[baseline=(a.base)]
    \node[draw,rounded corners=1mm,line width=1pt,inner sep=0.7ex] (a) {\Large#1};% <-- We don't want a space here
}

\begin{document}
  \begin{itemize}[label=$\bullet$]
    \item \firsthour{Hour} is aligned (w.r.t. normal size text),
    \item \firsthour{Hour} is not centered, but
    \item \firsthour{3 p.m.} is centered.
  \end{itemize}
  \bigskip

  \begin{itemize}[label=\Large$\bullet$]
    \item \firsthour{Hour} is aligned (w.r.t. large size text),
    \item \firsthour{Hour} is not centered, but
    \item \firsthour{3 p.m.} is centered.
  \end{itemize}
  \bigskip

  \begin{itemize}[label=$\bullet$]
    \item \secondhour{Hour} is aligned (w.r.t. normal size text),
    \item \secondhour{Hour} is centered, and
    \item \secondhour{3 p.m.} is centered.
  \end{itemize}
\end{document}

对节点的基线位置进行一些手动调整：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes.misc}
\usepackage{enumitem}
\newcommand{\hour}[1]{\tikz[baseline=-0.5ex]{
  \node[draw, rounded corners=1mm, very thick,
         text depth=0.25ex, 
        font=\Large] (a) {#1}}
                      }

\begin{document}
  \begin{itemize}[label=$\bullet$]
    \item \hour{Hour}
\end{itemize}
\end{document}
