Question

\tableofcontents我想為in建立以下模板beamer。

我能夠使用以下 MWE生成sections列表的程式碼subsections

\documentclass{beamer}
\usepackage[english]{babel}
\usepackage{tikz}
\setbeamerfont{section in toc}{family*=qag, size=\large,series=\bfseries}
\setbeamerfont{subsection in toc}{size=\normalsize,series=\bfseries}
\setbeamertemplate{subsection in toc}{%
    \begin{tikzpicture}[outer sep=0pt, inner sep=0pt,line width=0pt]
        \path[use as bounding box] (0,0) rectangle (\textwidth,0);
        \node[anchor=base east] at (.7\textwidth,0) { \inserttocsubsection};
    \end{tikzpicture}
}
\setbeamertemplate{section in toc}{%
    \begin{tikzpicture}[outer sep=0pt, inner sep=0pt,line width=0pt]
        \path[use as bounding box] (0,0) rectangle (\textwidth,0);
        \node[anchor=base east] at (.7\textwidth,0) { \inserttocsection};
        \node[anchor=base west] at (.7\textwidth+4ex+2.2ex,0){\inserttocsectionnumber};
    \end{tikzpicture}
}
\begin{document}
\begin{frame}
\tableofcontents
\end{frame}

\section{First Section}
\section{Second Section}
\subsection{A subsection}
\begin{frame}{Some frame}
\end{frame}
\end{document}

但是，我沒有找到插入垂直線的明智方法。如果我使用background模板，我可以做到，但定位並不容易（並且強烈依賴 和aspectratio）margins。同樣的情況也發生overlay在 中tikzpicture。我試圖找到一種方法將section in toc模板包含在 a 中tikzpicture並將每個模板定義為節點的集合，但它似乎\tableofcontets比我想像的更複雜。例如，使用\patchcmd並不是一個好的選擇。

您可以標記節點，然後從第一部分到最後一部分繪製線條：

\documentclass{beamer}
\usepackage[english]{babel}
\usepackage{tikz}
\setbeamerfont{section in toc}{family*=qag, size=\large,series=\bfseries}
\setbeamerfont{subsection in toc}{size=\normalsize,series=\bfseries}
\setbeamertemplate{subsection in toc}{%
    \begin{tikzpicture}[outer sep=0pt, inner sep=0pt,line width=0pt]
        \path[use as bounding box] (0,0) rectangle (\textwidth,0);
        \node[anchor=base east] at (.7\textwidth,0) { \inserttocsubsection};
    \end{tikzpicture}
}
\setbeamertemplate{section in toc}{%
    \begin{tikzpicture}[outer sep=0pt, inner sep=0pt,line width=0pt,remember picture]
        \path[use as bounding box] (0,0) rectangle (\textwidth,0);
        \node[anchor=base east] (toc-\inserttocsectionnumber) at (.7\textwidth,0) { \inserttocsection};
        \node[anchor=base west] at (.7\textwidth+4ex+2.2ex,0){\inserttocsectionnumber};
    \end{tikzpicture}
}

\makeatletter
\apptocmd{\tableofcontents}{%
\begin{tikzpicture}[remember picture,overlay]
\draw[red,line width=0.1cm] ([xshift=4.1ex,yshift=2ex]toc-1.north east) -- ([xshift=4.1ex,yshift=-2ex]toc-\the\[email protected] east);
\end{tikzpicture}%
}{}{}
\makeatother

\begin{document}
\begin{frame}
\tableofcontents
\end{frame}

\section{First Section}
\begin{frame}
\frametitle{Some frame}
\end{frame}
\section{Second Section}
\subsection{A subsection}
\begin{frame}
\frametitle{Some frame}
\end{frame}
\section{Third Section}
\begin{frame}
\frametitle{Some frame}
\end{frame}
\end{document}

如果您的最後一部分要包含小節，您也可以標記它們並使用https://topanswers.xyz/tex?q=1987#a2230找出最後一段編號。
