我怎样才能以非列表样式更智能地格式化投影仪 \tableofcontents？

我目前有一个用例，其中为 PowerPoint 创建了一组图形精美的目录幻灯片，我想复制 LaTeX 投影仪的设计，同时保留自动填充当前内容的功能，这些内容通常会被弹出到而\tableofcontents不是tikzpicture正常的列表环境中。我最好在不需要双重编译的情况下执行此操作（通过固定锚点和remember picture,overlay。

这就是我最终想要实现的目标： 在此处输入图片描述

当然原版更有吸引力。;-)

这是显示静态代码（可防止双重编译）的当前版本，它会生成花哨的 ToC，但不会自动生成，还会更改模板section in toc，这需要双重编译：

\documentclass{beamer}

\usepackage{tikz}
\usetikzlibrary{calc}

\tikzset{bubble/.style={circle,text width=2cm,align=center,inner sep=2pt}}

\makeatletter
\setbeamertemplate{section in toc}{
    \ifnum\the\beamer@tempcount=1
    \begin{tikzpicture}[remember picture,overlay]
        \fill[green] ($(current page.south west) + (1cm,1cm)$) rectangle ($(current page.north east) - (1cm,1cm)$);
        \node(first)[bubble,fill=red] at ($(current page.south west) + (2.4cm,2.5cm)$) {0\inserttocsectionnumber\\ \inserttocsection};
    \end{tikzpicture}
    \fi
    \ifnum\the\beamer@tempcount=2
    \begin{tikzpicture}[remember picture,overlay]
        \node(second)[bubble,fill=orange] at ($(current page.south west) + (4.5cm,7.2cm)$) {0\inserttocsectionnumber\\ \inserttocsection};
        \draw (first) -- (second);
    \end{tikzpicture}
    \fi
    \ifnum\the\beamer@tempcount=3
    \begin{tikzpicture}[remember picture,overlay]
    \node(third)[bubble,fill=magenta] at ($(current page.south west) + (6cm,3cm)$) {0\inserttocsectionnumber\\ \inserttocsection};
    \draw (second) -- (third);
    \end{tikzpicture}
    \fi
    \ifnum\the\beamer@tempcount=4
    \begin{tikzpicture}[remember picture,overlay]
    \node(fourth)[bubble,fill=pink] at ($(current page.south west) + (8cm,7cm)$) {0\inserttocsectionnumber\\ \inserttocsection};
    \draw (third) -- (fourth);
    \end{tikzpicture}
    \fi
    \ifnum\the\beamer@tempcount=5
    \begin{tikzpicture}[remember picture,overlay]
    \node(fifth)[bubble,fill=cyan] at ($(current page.south west) + (10cm,3cm)$) {0\inserttocsectionnumber\\ \inserttocsection};
    \draw (fourth) -- (fifth);
    \end{tikzpicture}
    \fi
    \,%
}
\makeatother

\begin{document}

\begin{frame}
\begin{tikzpicture}
    \fill[green] (0,0) rectangle ++(\textwidth,0.85\textheight);
    \node(first)[bubble,fill=red] at (0.15\textwidth,0.15\textheight) {01\\First Chapter};
    \node(second)[bubble,fill=orange] at (0.3\textwidth,0.7\textheight) {02\\Second Chapter};

    \node(fifth)[bubble,fill=cyan] at (0.8\textwidth,0.2\textheight) {05\\Fifth Chapter};
    \draw (first) -- (second) -- (third) -- (fourth) -- (fifth);
\end{tikzpicture}
\end{frame}

我尝试了一下修补\tableofcontents，但我仍然找不到不编译两次的方法，因为这是引用另一个中的节点所必需的tikzpicture：

\colorlet{bubbleColor}{green}
\tikzset{bubble/.style={circle,fill=bubbleColor,text width=2cm,align=center,inner sep=2pt}}

\usepackage{etoolbox,xfp}
\pretocmd{\tableofcontents}{%
    \begin{tikzpicture}[remember picture]
    \fill[green] (0,0) rectangle ++(\textwidth,0.85\textheight);
    \coordinate(section1) at (0.15\textwidth,0.15\textheight);
    \coordinate(section2) at (0.3\textwidth,0.7\textheight);
    \coordinate(section3) at (0.45\textwidth,0.3\textheight);
    \coordinate(section4) at (0.7\textwidth,0.7\textheight);
    \coordinate(section5) at (0.8\textwidth,0.2\textheight);
    \end{tikzpicture}}{}{}
\apptocmd{\tableofcontents}{}{}{}

\makeatletter
\setbeamertemplate{section in toc}{
    \ifodd\the\beamer@tempcount
        \colorlet{bubbleColor}{red}
    \else
        \colorlet{bubbleColor}{magenta}
    \fi
    \ifnum\the\beamer@tempcount=1
    \begin{tikzpicture}[remember picture,overlay]
        \node(section\inserttocsectionnumber)[bubble] at (section\inserttocsectionnumber) {0\inserttocsectionnumber\\ \inserttocsection};
    \end{tikzpicture}
    \else
        \ifnum\the\beamer@tempcount<6
        \begin{tikzpicture}[remember picture,overlay]
            \node(section\inserttocsectionnumber)[bubble] at (section\inserttocsectionnumber) {0\inserttocsectionnumber\\ \inserttocsection};
            \draw (section\inteval{\inserttocsectionnumber - 1}) -- (section\inserttocsectionnumber);
        \end{tikzpicture}
        \fi
    \fi
}
\makeatother

基于https://topanswers.xyz/tex?q=1987#a2230

第一次运行会出现错误，但你可以添加一些异常处理。第二次运行时，tikz 图片应该会出现

现在，我的解决方案是先定义自己的命令，然后读取文件，而不是操纵\tableofcontents命令或摆弄文件。如下所示：TOCTOC

\documentclass{beamer}

\usepackage{tikz}
\usetikzlibrary{calc}

\colorlet{bubbleColor}{orange}
\tikzset{bubble/.style={circle,fill=bubbleColor,text width=1.5cm,align=center,inner sep=2pt,font=\small}}

\begin{document}


\makeatletter
\let\beameroriginal@sectionintoc\beamer@sectionintoc

%%%%\def\beamer@endinputifotherversion#1{}
\renewcommand{\beamer@sectionintoc}[5]{ \ifodd#1%
    \colorlet{bubbleColor}{red}%
    \else%
    \colorlet{bubbleColor}{magenta}%
    \fi%
    \node(bubble#1)[bubble] at (section#1) {#2};}
%%%%\def\beamer@subsectionintoc#1#2#3#4#5#6{}
%%%%\def\beamer@subsubsectionintoc#1#2#3#4#5#6#7{}

\frame{
    \begin{tikzpicture}
    \fill[green] (0,0) rectangle ++(\textwidth,0.85\textheight);
    \coordinate(section1) at (0.15\textwidth,0.15\textheight);
    \coordinate(section2) at (0.3\textwidth,0.7\textheight);
    \coordinate(section3) at (0.45\textwidth,0.3\textheight);
    \coordinate(section4) at (0.7\textwidth,0.7\textheight);
    \coordinate(section5) at (0.8\textwidth,0.2\textheight);
    \@input{\jobname.toc}
    \draw (bubble1) -- (bubble2) -- (bubble3) -- (bubble4) -- (bubble5);
    \end{tikzpicture}
}

\let\beamer@sectionintoc\beameroriginal@sectionintoc
\makeatother

\frame{\tableofcontents}

\section{First Chapter}
\frame{Test}
\section{Second Chapter}
\frame{Test}
\section{Third Chapter}
\frame{Test}
\section{Fourth Chapter}
\frame{Test}
\section{Fifth Chapter}
\frame{Test}

\end{document}
