Beamer: tableofcontents with page numbers up to subsubsections

beamertable of contents

Thanks to the wonderful code of Gonzalo Medina (tableofcontents with page numbers), one can show frame numbers of sections and subsections in TOC. If my table of contents has subsubsections. These subsubsections don't have their frame numbers in TOC. I guess one can modify the above code. However, I am just a beginner to beamer. So any help is truly appreciated.

Here is the code:

\documentclass{beamer}
\usetheme{CambridgeUS}

\newcounter{sectionpage}

\makeatletter
\long\def\beamer@section[#1]#2{%
    \beamer@savemode%

    \ifbeamer@inlecture
    \refstepcounter{section}%
    \beamer@ifempty{#2}%
    {\long\def\secname{#1}\long\def\lastsection{#1}}%
    {\global\advance\beamer@tocsectionnumber by 1\relax%
        \long\def\secname{#2}%
        \long\def\lastsection{#1}%
        \setcounter{sectionpage}{\insertframenumber}\stepcounter{sectionpage}%
        \addtocontents{toc}{\protect\beamer@sectionintoc{\the\c@section}{#2\dotfill\thesectionpage}{\the\c@page}{\the\c@part}%
            {\the\beamer@tocsectionnumber}}}%

Welcome to TeX.SX! The code you present essentially just copies the default commands and adds the page numbers. Therefore, you just need to do the same for \beamer@subsubsection.

However, I would suggest that you patch the underlying commands instead of copying the whole defintions to reduce the amount of code in your preamble.

\documentclass{beamer}
\usetheme{CambridgeUS}
    
\newcounter{sectionpage}
\makeatletter

\patchcmd{\beamer@section}
    {\addtocontents{toc}{\protect\beamer@sectionintoc{\the\c@section}{#2}{\the\c@page}{\the\c@part}{\the\beamer@tocsectionnumber}}}
    {\setcounter{sectionpage}{\insertframenumber}\stepcounter{sectionpage}%
     \addtocontents{toc}{\protect\beamer@sectionintoc{\the\c@section}{#2\dotfill\thesectionpage}{\the\c@page}{\the\c@part}{\the\beamer@tocsectionnumber}}}
    {}{}
    
\patchcmd{\beamer@subsection}
    {\addtocontents{toc}{\protect\beamer@subsectionintoc{\the\c@section}{\the\c@subsection}{#2}{\the\c@page}{\the\c@part}{\the\beamer@tocsectionnumber}}}
    {\setcounter{sectionpage}{\insertframenumber}\stepcounter{sectionpage}%
     \addtocontents{toc}{\protect\beamer@subsectionintoc{\the\c@section}{\the\c@subsection}{#2\dotfill\thesectionpage}{\the\c@page}{\the\c@part}{\the\beamer@tocsectionnumber}}}
    {}{}
    
\patchcmd{\beamer@subsubsection}
    {\addtocontents{toc}{\protect\beamer@subsubsectionintoc{\the\c@section}{\the\c@subsection}{\the\c@subsubsection}{#2}{\the\c@page}{\the\c@part}{\the\beamer@tocsectionnumber}}}
    {\setcounter{sectionpage}{\insertframenumber}\stepcounter{sectionpage}%
     \addtocontents{toc}{\protect\beamer@subsubsectionintoc{\the\c@section}{\the\c@subsection}{\the\c@subsubsection}{#2\dotfill\thesectionpage}{\the\c@page}{\the\c@part}{\the\beamer@tocsectionnumber}}}
    {}{}

\makeatother

\AtBeginSection[] % Do nothing for \section*
{
    \begin{frame}<beamer>
        \frametitle{Outline}
        \tableofcontents[currentsection]

}

[Tex/LaTex] Customizing Beamer’s Table of Contents

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.

[Tex/LaTex] LaTeX Beamer: Frame outside sections

To effectively get a no section section, use:

\section*{} or \section{}

as in the following variant of your code:

\documentclass{beamer}
%\url{http://tex.stackexchange.com/q/66628/86}
\usetheme{Frankfurt}

\begin{document}
\begin{frame}
\tableofcontents
\end{frame}

\section{Sec1}
\begin{frame}
\frametitle{Frame1}
\end{frame}

\section{Sec2}
\begin{frame}
\frametitle{Frame2}
\end{frame}

\section{} % or \section*{}
\begin{frame}
\frametitle{Frame3}
\end{frame}

\end{document}

This produces the following:

Beamer frame with no section

As far as I can tell by experimenting, the section command is a bit strange in what it can and cannot accept. The most general form is \section<*>[Optional]{Mandatory}. However, it appears that the * and the Optional are incompatible (even if the Optional is empty). So you can have a star or an optional argument, but not both. With that proviso, the possible combinations are:

\section{Text}: Text is in the TOC and the navigation.
\section{}: omitted completely from TOC and navigation (not even allocated space)
\section[Text]{Long Text}: Long Text is used in TOC, Text in navigation.
\section[]{Text}: Text is in the TOC, nothing in navigation.
\section[]{}: Nothing in either place.
\section*{}: omitted completely from TOC and navigation
\section*{Text}: Nothing in TOC, Text used in navigation

Here's some test code:

\documentclass{beamer}
%\url{http://tex.stackexchange.com/q/66628/86}
\usetheme{Frankfurt}

\begin{document}
\begin{frame}
\tableofcontents
\end{frame}

\section{NNT}
\begin{frame}{No Star, No Optional, Text}
\end{frame}

\section{}
\begin{frame}{No Star, No Optional, Empty}
\end{frame}

\section[NOT(S)]{NOT}
\begin{frame}{No Star, Optional, Text}
\end{frame}

\section[NOE]{}
\begin{frame}{No Star, Optional, Empty}
\end{frame}

\section[]{NET}
\begin{frame}{No Star, Empty Optional, Text}
\end{frame}

\section[]{}
\begin{frame}{No Star, Empty Optional, Empty}
\end{frame}

\section*{SNT}
\begin{frame}{Star, No Optional, Text}
\end{frame}

\section*{}
\begin{frame}{Star, No Optional, Empty}
\end{frame}

\section*[SOT(S)]{SOT}
\begin{frame}{Star, Optional, Text}
\end{frame}

\section*[SOE]{}
\begin{frame}{Star, Optional, Empty}
\end{frame}

\section*[]{SET}
\begin{frame}{Star, Empty Optional, Text}
\end{frame}

\section*[]{}
\begin{frame}{Star, Empty Optional, Empty}
\end{frame}
\end{document}

That seems to allow for every possibility except that you want to have a section with a proper title which appears neither in the TOC nor in the navigation. Fortunately, that isn't the case here. The best I can come up with in that situation is to temporarily disable \addtocontents as this inhibits writing to the toc file (for the ... wait for it ... table of contents) and the nav file (for the navigation bar) but allows everything else to go through. Looking at the code, at least one of these files is written to if the \section command is given any argument whatsoever so this seems to be the only way. It could be wrapped up a bit more fancily, but in essence it boils down to:

\let\origaddtocontents=\addtocontents
\def\dontaddtocontents#1#2{} % or \@gobbletwo if in \makeatletter ... \makeatother

...

\let\addtocontents=\dontaddtocontents
\section{Invisible Section}
\let\addtocontents=\origaddtocontents
