在 AtBeginSection 中隐藏导航栏框架

在 AtBeginSection 中隐藏导航栏框架

我想在演示文稿的每个部分开头添加目录，但不在导航栏中显示框架。我尝试了以下操作：

\AtBeginSection[]
{
  {
    \makeatletter
    \def\beamer@writeslidentry{\clearpage\beamer@notesactions}
    \makeatother
    \frame{
      \frametitle{Table of contents}
      \tableofcontents[
      currentsection,
      subsectionstyle=show/show/hide
      ]
    }
  }
}

这样可以正确显示框架，但不会将其从导航栏中隐藏。如果我手动将内部块移动到每个部分的开头，则此操作可以正常工作（请参阅下面的完整代码）。

我怎样才能解决这个问题？

我在这里找到了上述内容，但它不在AtBeginSection：

完整示例：

\documentclass[usenames,dvipsnames,svgnames,table]{beamer}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usetheme{Madrid}

\useoutertheme{miniframes}
\useinnertheme{circles}

% This one shows in the navigation bar -> Not good.
\AtBeginSection[]
{
  {
    \makeatletter
    \def\beamer@writeslidentry{\clearpage\beamer@notesactions}
    \makeatother
    \frame{
      \frametitle{Table of contents}
      \tableofcontents[
      currentsection,
      subsectionstyle=show/show/hide
      ]
    }
  }
}

\begin{document}

\section{Section 1}

% This one does not show in the navigation bar -> Ok.
{
  \makeatletter
  \def\beamer@writeslidentry{\clearpage\beamer@notesactions}
  \makeatother
  \frame{
    \frametitle{Table of contents}
    \tableofcontents[
    currentsection,
    subsectionstyle=show/show/hide
    ]
  }
}

\end{document}

非常肮脏的黑客行为：

\documentclass{beamer}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usetheme{Madrid}
\useoutertheme{miniframes}

\makeatletter
\let\beamer@writeslidentry@miniframeson=\beamer@writeslidentry%
\def\beamer@writeslidentry@miniframesoff{%
  \expandafter\beamer@ifempty\expandafter{\beamer@framestartpage}{}% does not happen normally
  {%else
    % removed \addtocontents commands
    \clearpage\beamer@notesactions%
  }
}
\newcommand*{\miniframeson}{\let\beamer@writeslidentry=\beamer@writeslidentry@miniframeson}
\newcommand*{\miniframesoff}{\let\beamer@writeslidentry=\beamer@writeslidentry@miniframesoff}
\makeatother

\setbeamertemplate{section in head/foot}{\hspace*{1.7ex}\insertsectionhead}

\makeatletter
\setbeamertemplate{headline}{%
  \begin{beamercolorbox}[colsep=1.5pt]{upper separation line head}
  \end{beamercolorbox}
  \begin{beamercolorbox}{section in head/foot}
    \vskip2pt\hspace*{-1.7ex}\insertnavigation{1.01\paperwidth}\vskip2pt
  \end{beamercolorbox}%
  \ifbeamer@theme@subsection%
    \begin{beamercolorbox}[colsep=1.5pt]{middle separation line head}
    \end{beamercolorbox}
    \begin{beamercolorbox}[ht=2.5ex,dp=1.125ex,%
      leftskip=.3cm,rightskip=.3cm plus1fil]{subsection in head/foot}
      \usebeamerfont{subsection in head/foot}\insertsubsectionhead
    \end{beamercolorbox}%
  \fi%
  \begin{beamercolorbox}[colsep=1.5pt]{lower separation line head}
  \end{beamercolorbox}
}
\makeatother

\AtBeginSection[]{%
    \miniframesoff
    \begin{frame}
      \frametitle{Table of contents}
      \tableofcontents[
      currentsection,
      subsectionstyle=show/show/hide
      ]
    \end{frame}
    \miniframeson
}



\begin{document}

\section{Section 1}

\begin{frame}

\end{frame}

\begin{frame}

\end{frame}

\section{Section 2}

\begin{frame}

\end{frame}

\end{document}

您可以重新定义 \section为在执行旧代码后始终执行目录代码\section。将以下内容添加到您的序言中：

\makeatletter
\newcommand\mytableofcontents{%
   \begingroup
   \def\beamer@writeslidentry{\clearpage\beamer@notesactions}%
   \frame{%
      \frametitle{Table of contents}%
      \tableofcontents[%
        currentsection,
        subsectionstyle=show/show/hide
      ]%
   }%
   \endgroup
}
\let\orig@section\section
\renewcommand\section[1]{\orig@section{#1}\mytableofcontents}
\makeatother

如果您决定也使用某处的可选参数\section，则必须\section相应地重新定义以处理它。
