显示缩进目录时保留 Beamer 的内部主题

Question

跟进“Beamer – 如何使用编号目录来获得子部分缩进？”，有没有办法缩进目录中的项目，以便所选的内部主题也适用于目录？

以下示例成功修改了目录项的缩进，但未能将所选主题应用于编号（请参阅环境enumerate以进行比较）：

\documentclass{beamer}
\useinnertheme{circles}

\begin{document}

\setbeamertemplate{section in toc}{\leavevmode\leftskip=3.2em\rlap{\hskip-2em\inserttocsectionnumber}\inserttocsection\par}

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

\section{One}
\section{Two}
\section{Three}

\begin{frame}
    Chosen Few
    \begin{enumerate}
        \item One
        \item Two
        \item Three
    \end{enumerate}
\end{frame}

\end{document}

Answer 1

你可以\defbeamertemplate{section in toc}{circle}从\defbeamertemplate{subsection in toc}{circle}beamerbaseauxtemplates.sty作为起点并根据需要更改 leftskip：

\documentclass{beamer}
\useinnertheme{circles}

\makeatletter
\setbeamertemplate{section in toc}
{\leavevmode\leftskip=4ex% Change value here, origionally 2ex
  \llap{%
    \usebeamerfont*{section number projected}%
    \usebeamercolor{section number projected}%
    \begin{pgfpicture}{-1ex}{0ex}{1ex}{2ex}
      \color{bg}
      \pgfpathcircle{\pgfpoint{0pt}{.75ex}}{1.2ex}
      \pgfusepath{fill}
      \pgftext[base]{\color{fg}\inserttocsectionnumber}
    \end{pgfpicture}\kern1.25ex%
  }%
  \inserttocsection\par}

\setbeamertemplate{subsection in toc}
{\leavevmode\leftskip=2em\inserttocsubsection\par}
\makeatother

\begin{document}

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

\section{One}
\section{Two}
\section{Three}

\begin{frame}
    Chosen Few
    \begin{enumerate}
        \item One
        \item Two
        \item Three
    \end{enumerate}
\end{frame}

\end{document}
