在 beamer 类中设置下一个子子节

Question

我需要在 beamer 类中手动设置子子部分编号，因此使用以下代码：

\newcommand{\setnextsubsubsection}[1]{%
  \setcounter{subsubsection}{\numexpr#1-1\relax}%
  \beamer@tocsubsubsectionnumber=\numexpr#1\relax\space}

相同的代码对于部分工作正常，但当我使用\setnextsubsubsection它时说

!undefined control sequence. \setnextsubsubsection...

是因为\beamer@tocsubsubsectionnumber =不起作用吗？

这是一个（希望是）最小的例子：

\documentclass[mathserif, handout]{beamer}

\usepackage[polish,german]{babel}
\usepackage[utf8]{inputenc}

\setbeamerfont{frametitle}{size=\linespread{1.1}\Large}
\newcommand{\sectiontitle}{\huge \bf \color{blau} \thesection . \insertsection}
\newcommand{\subsectiontitle}{\thesubsection . \subsecname}
\newcommand{\subsubsectiontitle}{\thesubsubsection . \subsubsecname }


\defbeamertemplate{subsubsection in toc}{subsubsections numbered}
{\leavevmode\tiny\leftskip=3em%
 \rlap{\hskip-3em\inserttocsectionnumber.\inserttocsubsectionnumber.\inserttocsubsubsectionnumber}%
 \inserttocsubsubsection\par}
\setbeamertemplate{section in toc}[sections numbered]
\setbeamertemplate{subsection in toc}[subsections numbered]
\setbeamertemplate{subsubsection in toc}[subsubsections numbered]

\makeatletter
\newcommand{\setnextsection}[1]{%
  \setcounter{section}{\numexpr#1-1\relax}%
  \beamer@tocsectionnumber=\numexpr#1-1\relax\space}

Answer 1

好的，我想我已经解决掉了。

beamer只使用subsubsection计数器而不\beamer@tocsubsubsectionnumber计数。使用以下定义似乎就足够了：

\newcommand{\setnextsubsubsection}[1]{%
  \setcounter{subsubsection}{\numexpr#1-1\relax}}

结果：

手册仍然beamer建议根本不要使用\subsubsections（并声称如果您按照所说的去做，您将会做出更好的演示）。
