使目录适合侧边栏 - beamer

Question

我在使用 Beamer 的侧边栏时遇到了问题。我使用的是 PaloAlto 主题，有太多部分和子部分，所以它超出了框架的范围。我读到过我可以减小字体大小，想知道当侧边栏在主题中预定义时，是否有办法减少每个部分标题之间的空间？谢谢！

编辑-这里是（缩短的）前导代码和问题的图片：

    \documentclass[pdftex, mathserif/mathsans, red]{beamer}

    \usetheme{PaloAlto}


    \usecolortheme{beaver}

    \setbeamercolor*{title in sidebar}{fg=darkred!50!black}
    \setbeamercolor*{author in sidebar}{fg=darkgray}
    \setbeamercolor*{section in sidebar}{fg=gray}
    \setbeamercolor*{subsection in sidebar}{fg=gray}


    \setbeamercovered{transparent}

    \mode<presentation>


    \begin{document}

您可以看到侧边栏中的标题超出了空间。

Answer 1

• 您可以使用以下方式更改侧边栏中各部分的字体大小\setbeamerfont{section in sidebar}{size=\Tiny}

• 要更改垂直间距，您可以像这样重新定义section in sidebar和模板：section in sidebar shaded

\documentclass{beamer}

\usetheme{PaloAlto}
\usecolortheme{beaver}

\setbeamercolor*{title in sidebar}{fg=darkred!50!black}
\setbeamercolor*{author in sidebar}{fg=darkgray}
\setbeamercolor*{section in sidebar}{fg=gray}
\setbeamercolor*{subsection in sidebar}{fg=gray}


\setbeamercovered{transparent}

\mode<presentation>

\setbeamerfont{section in sidebar}{size=\Tiny}

\makeatletter
\setbeamertemplate{section in sidebar}
{%
  \vbox{%
    \vskip-5ex% <- was 1ex by default
    \beamer@sidebarformat{3pt}{section in sidebar}{\insertsectionhead}%
  }%
}

\setbeamertemplate{section in sidebar shaded}
{%
  \vbox{%
    \vskip-5ex% <- was 1ex by default
    \beamer@sidebarformat{3pt}{section in sidebar shaded}{\insertsectionhead}%
  }%
}
\makeatother

\section{title}
\begin{frame}

\section{title}
