\insertsectionnumber와 \inserttocsectionnumber의 차이점

Question

다음 비머 코드

\documentclass{beamer}

\setbeamertemplate{section in toc}[sections numbered]

\begin{document}

\frame{\tableofcontents}

\section{section one}
\frame{\insertsectionnumber\quad\insertsection}

\section*{section two}
\frame{\insertsectionnumber\quad\insertsection}

\section{section three}
\frame{\insertsectionnumber\quad\insertsection}

\end{document}

다음 결과를 제공하십시오.

나는 그것이 명령을 \tableofcontents호출한다는 것을 알고 있습니다 \inserttocsectionnumber. 몇 가지 \section*명령이 있을 \inserttocsectionnumber때\insertsectionnumber 다른 결과를 제공하는2 섹션 3그리고3 섹션 3. 왜?

Answer 1

이것은 beamerbasesection.sty주석이 포함된 의 일부 코드입니다.

와 같은 표준 클래스와는 달리 카운터 의 스테핑과 관련하여 \section차이 가 없습니다 . 따라서 명령 을 실행해도 카운터가 증가합니다 .\section*sectionarticlesection\section*

이것은 버그인가요? 아니요, 내 생각에는 Google의 다양한 고급 기능을 모두 장부에 기록하는 것이 더 쉬운 것 같습니다.beamer
