[Tex/LaTex] Beamer ToC Advanced Overlays

beamerformattingtable of contents

I want to have a Table of Contents in my Beamer presentation, but I want it to be laid out in an apparently particular way. For the first section, what I want is an overlay for each section (I currently have 3) with the nth section "shown" and the others shaded. At the start of the other sections, I just want to show that section and have the others shaded. Those last ones I can do (I just can't use \AtBeginSection since my first section will be different) and looking at this post got me halfway to where I want, but I want to be able to make the other sections shaded again. My code present looks something like the following:

\documentclass[pdf,usenames,dvipsnames]{beamer}
\usepackage{graphicx}
...
\begin{document}
\section{Section 1}
    \setbeamercovered{still covered={\opaqueness<1->{20}},again covered={\opaqueness<1->{20}}}
    \begin{frame}{Table of Contents}
        \tableofcontents[pausesections]
    \end{frame}
    \setbeamercovered{invisible}
    \subsection{Subsection 1a}
     ...
\section{Section 2}
    \begin{frame}{Table of Contents}
        \tableofcontents[currentsection]
    \end{frame}
    \subsection{Subsection 2a}
    ...
\section{Section 3}
    \begin{frame}{Table of Contents}
        \tableofcontents[currentsection]
    \end{frame}
    \subsection{Subsection 3a}
     ...
\end{document}

You can specify the appearance of the table of contents with the sectionstyle and subsectionsectionstyle commands.

In your particular case you can use \tableofcontents[pausesections] for the first section (as you did before) and \tableofcontents[sectionstyle=show/shaded, subsectionstyle=show/show/shaded] for the following sections.

The full MWE look like:

\documentclass[pdf,usenames,dvipsnames]{beamer}

\setbeamercovered{transparent}

\begin{document}
\section{Section 1}
    \begin{frame}{Table of Contents}
        \tableofcontents[pausesections]
    \end{frame}
    \subsection{Subsection 1a}

\section{Section 2}
    \begin{frame}{Table of Contents}
        \tableofcontents[sectionstyle=show/shaded, subsectionstyle=show/show/shaded]
    \end{frame}
    \subsection{Subsection 2a}

\section{Section 3}
    \begin{frame}{Table of Contents}
        \tableofcontents[sectionstyle=show/shaded, subsectionstyle=show/show/shaded]
    \end{frame}
    \subsection{Subsection 3a}

\end{document}

For specific subsections you may modify the behavior before they start: you could change \AtBeginSubsection locally. This means you could change that, for a subsection, but keep this change local by enclosing it within a group. For example, disabling \AtBeginSubsection and thus the subsection TOC:

\begingroup
\AtBeginSubsection{}
\subsection{No TOC}
\begin{frame}
...
\end{frame}
\endgroup
\subsection{Here's a TOC}

After the group ended, the globally by \AtBeginSubsection defined macro returns being active. The following subsections will show the TOC - I tested it.

This works because \AtBeginSubsection uses \def to redefine internal macros, which works local, thus visible only inside a group, in contrary to \gdef.

The beamer documentclass works in a very similar way to regular LaTeX documentclasses. Moreover, it necessarily includes the use of the hyperref package. That is, compiling even this minimal example (taken from the beamer documentclass documentation)

\documentclass{beamer}
% This is the file main.tex
\usetheme{Berlin}
\title{Example Presentation Created with the Beamer Package}
\author{Till Tantau}
\date{\today}
\begin{document}
\begin{frame}
\titlepage
\end{frame}
\section*{Outline}
\begin{frame}
\tableofcontents
\end{frame}
\section{Introduction}
\subsection{Overview of the Beamer Class}
\subsection{Overview of Similar Classes}
\section{Usage}
\subsection{...}
\subsection{...}
\section{Examples}
\subsection{...}
\subsection{...}
\begin{frame}
\end{frame} % to enforce entries in the table of contents
\end{document}

produces a hyperlinked table of contents. Furthermore, some notable extracts from the documentation includes:

The empty frame at the end (which should be deleted later) ensures that the sections and subsections are actually part of the table of contents. This frame is necessary since a \section or \subsection command following the last page of a document has no effect. (Section 4.2 Step Two: Structure Your Presentation, p 29)

This implies that there is a requirement to use \frame{...} or \begin{frame}...\end{frame} is necessary for the correct setup of your presentation. It may be that you do not have proper frames set up, causing a problem with hyperlinks between your table of contents and sectional headings.

You can structure your text using the commands \section and \subsection. Unlike standard LATEX, these commands will not create a heading at the position where you use them. Rather, they will add an entry to the table of contents and also to the navigation bars. (Section 10.2 Adding Sections and Subsections, p 95)

With the proper setup, \section and \subsection commands should link to the table of contents.
