框架标题投影仪下的简单迷你框架

我有一个简单的黑色投影仪模板，我经常使用它来演示。我想为它添加一些简单的迷你框架导航，但迷你框架的外部主题添加了太多额外的东西（部分名称等）。

我想在框架标题下方添加迷你框架圆圈，不带任何文字或分隔符来表示 pdf 中的部分更改。每个框架只有一个圆圈，以框架标题下方的细线为中心。但我确实希望在 pdf 中有一些部分，以便在查看文件时进行常规导航。

它看起来像这样... 在此处输入图片描述

我研究了从外部主题“mini-frame” .sty 改编代码，但这超出了我的技能。

这是我的 MWE：

\documentclass{beamer}
\setbeamertemplate{itemize items}[circle]
\setbeamercolor{itemize item}{fg=black}
\setbeamercolor{section in head/foot}{fg=white, bg=black}
\setbeamercolor{frametitle}{fg=white, bg=black}
\setbeamerfont{frametitle}{size=\small}
\setbeamertemplate{navigation symbols}{ }
\usefonttheme{serif}
\begin{document}


\section{Some Amazing Presentation}
\begin{frame}{MWE $\vert$ Some Amazing Presentation}
\begin{itemize}
\item This is a really amazing presentation, demonstrating a MWE
\item Very impressive
\end{itemize}
\end{frame}

\section{The Second Part}
\begin{frame}{MWE $\vert$ The Second Part}
\begin{itemize}
\item The second part of this presentation is even better
\item It was really worth waiting for
\end{itemize}
\end{frame}


\begin{frame}{MWE $\vert$ The Second Part}
\begin{itemize}
\item Lots of things to say
\item these things are interesting
\end{itemize}
\end{frame}


\begin{frame}{MWE $\vert$ The Second Part}
\begin{itemize}
\item blah blah blah
\item la la la
\end{itemize}
\end{frame}


\section{The End}
\begin{frame}{MWE $\vert$ The End}
\begin{itemize}
\item But the end is really the best part
\end{itemize}
\end{frame}


\end{document}

这应该可以按你期望的方式工作：

\documentclass{beamer}
\setbeamertemplate{itemize items}[circle]
\setbeamercolor{itemize item}{fg=black}
\setbeamercolor{section in head/foot}{fg=white, bg=black}
\setbeamerfont{frametitle}{size=\small}
\setbeamertemplate{navigation symbols}{ }
\usefonttheme{serif}
\setbeamercolor{frametitle}{fg=white,bg=black}

\setbeamercolor{mini frame}{fg=white}

\makeatletter
\def\insertsubsectionnavigationhorizontal#1#2#3{%

上述解决方案需要：

  1. 重写默认的迷你框架导航，以便不打印任何部分名称（\makeatletter和之间的部分\makeatother）。
  2. frame title嵌入新导航系统（\setbeamertemplate{frametitle}宏）的自定义模板。

请注意，您的 MWE 中没有子部分，而子部分是迷你框架导航正常工作所必需的。如果您不想要/不需要子部分，只需为每个部分引入一个虚拟的单个子部分（您也可以将其从目录中排除）。

对于单个子节，灰色项目符号将指示来自其他节的框架，因为每个节都包含单个子节。
