编辑部分 Beamer 标题（使用现有主题内容）

分数维：

考虑以下最小工作示例：

\documentclass{beamer}
\usetheme{CambridgeUS}

\begin{document}

\section{Section1}
\subsection{Subsection1}
\begin{frame}
\end{frame}

\subsection{Subsection2}
\begin{frame}
\end{frame}

\end{document}

呈现如下： 在此处输入图片描述

问题 ：

我想删除放置在标题右侧的自动内容（内容subsection），并在那里放置一些点计算当前剩余的幻灯片数量section。通过点我是说 ：

  • 的数量点告诉我们该部分有多少张幻灯片（不考虑停顿！）；
  • 如果它们是白色的，我们读幻灯片
  • 如果为空：
    1. 空白一片，我们正在读它；
    2. 如果它们是空的灰色，则表示我们尚未读取它们。

看起来它已经存在了：

我在其他一些主题上也看到过这种点，比如法兰克福：

我猜想它可以被利用，但是我对乳胶的了解不够深入，无法做到这一点。

预期显示示例：

在此示例中，我们有 6 页针对此 Section1，并且我们当前位于此部分的第二页。

（当然背景不一定是黑色的，只是手工编辑得不好）

概括 ：

我怎样才能把这些点而不是小节放在这个美国剑桥大学主题？是否可以整合法兰克福关于这些点的代码美国剑桥大学主题 ？

在此先感谢您的帮助。

答案1

这是另一种方法，尝试将法兰克福主题中的实际迷你框架导航嵌入剑桥主题。这需要大刀阔斧，我建议用它制作自定义主题。

首先，我们需要设置迷你框架的颜色，我darkred从beaver主题中选择了颜色以匹配主题的其余部分。

\setbeamercolor{迷你框架}{fg=darkred}

现在到了棘手的部分：我们将从 中取出代码\insertsubsectionnavigationhorizontal，删除其自身的\slideentry宏并添加从文件中取出的宏beamerbasenavigation.sty。由于我的etoolboxfu 不够好，我只会发布整个修改后的\slideentry。为了代码可读性等，这应该放在另一个文件中或用 完成etoolbox。

\def\insertsubsectionnavigationhorizontal#1#2#3{%
    \hbox to #1{{%
        \usebeamerfont{subsection in head/foot}\usebeamercolor[fg]{subsection in head/foot}
        \beamer@currentsubsection=0%
        \def\sectionentry##1##2##3##4##5{}%
        \def\slideentry##1##2##3##4##5##6{\ifnum##6=\c@part\ifnum##1=\c@section%
      \ifnum##2>\beamer@currentsubsection%
      \box\beamer@sectionbox\hskip1.875ex plus1fill%
            \hbox to 0pt{%
                    \global\beamer@section@min@dim\beamer@tempdim
                        \beamer@link(##4){%
                            \usebeamerfont{mini frame}%
                            \ifnum\c@section=##1%
                                \ifnum\c@subsection=##2%
                                    \usebeamercolor[fg]{mini frame}%
                                    \ifnum\c@subsectionslide=##3%
                                        \usebeamertemplate{mini frame}%\beamer@minislidehilight%
                                    \else%
                                        \usebeamertemplate{mini frame in current subsection}%\beamer@minisliderowhilight%
                                    \fi%
                                \else%
                                    \usebeamercolor{mini frame}%
                                    %\color{fg!50!bg}%
                                    \usebeamertemplate{mini frame in other subsection}%\beamer@minislide%
                                \fi%
                            \else%
                                \usebeamercolor{mini frame}%
                                                                %\color{fg!50!bg}%
                                \usebeamertemplate{mini frame in other subsection}%\beamer@minislide%
                            \fi%
                        }%
                \hskip-10cm plus 1fil%
            }%
            \fi\fi\fi\ignorespaces
        }%
        #2\hskip.3cm\setbox\beamer@sectionbox=\hbox{}%
        \hskip-1.875ex plus-1fill\dohead%
        \box\beamer@sectionbox\hfil\hskip.3cm%
        #3
    }}
}

最后一步是重新设置标题模板，以便它调用我们定制的水平小框架导航：

    \setbeamertemplate{headline}
    {
        \leavevmode%
        \hbox{%
        \begin{beamercolorbox}[wd=.5\paperwidth,ht=2.65ex,dp=1.5ex,right]{section in head/foot}%
            \usebeamerfont{section in head/foot}\bfseries\insertsectionhead\hspace*{2ex}
        \end{beamercolorbox}%
        \begin{beamercolorbox}[wd=.5\paperwidth,ht=2.65ex,dp=1.5ex,left]{subsection in head/foot}%
            \usebeamerfont{subsection in head/foot}\setbeamercolor{section in head/foot}{fg=black,bg=white}
            \vspace*{.01cm}\insertsubsectionnavigationhorizontal{0cm}{\hskip-.1cm}{}
        \end{beamercolorbox}}%
        \vskip0pt%
    }

结果。

它的工作原理与法兰克福迷你框架导航完全相同，因为它实际上是法兰克福小型框架导航。
