beamerpage-breakingtable of contents
I've got a rather long table of contents for my presentation in beamer, and it doesn't fit on one frame. I know I can provide a table of contents per section, or to manually break it between sections into a few frames using \tableofcontents[sections={1-3}] etc., but I was hoping there is a way for LaTeX/beamer to do it automatically for me.
So, in short:
Is it possible to automatically break the table of contents in beamer between frames?
And of course, if yes, how would I go about it?
Load (in the preamble) the multicol package:
\usepackage{multicol}
and then, in the body of your document:
\begin{frame}
\begin{multicols}{2}
\tableofcontents
\end{multicols}
\end{frame}
Edit: With the toc appearing all through the beamer, before the first frame:
\AtBeginSubsection[]
{
\begin{frame}<beamer>
\begin{multicols}{2}
\tableofcontents[currentsection,hideothersubsections]
\end{multicols}
\end{frame}
}
the initial solution I proposed (it's on the bottom now) was theme-dependent since it involved a redefinition of the footline template (which may vary from them to theme). Here now I present a simpler solution which doesn't depend on the theme used. The idea is to use the background canvas template and a \node (inside a tikzpicture environment with the remember picture,overlay options) to place the button at the desired location:
\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usepackage[brazil]{babel}
\usetheme{Boadilla}
\newcommand\AddButton{%
\setbeamertemplate{background canvas}{%
\begin{tikzpicture}[remember picture,overlay]
\node[anchor=west] at ([yshift=20pt,xshift=1em]current page.south west)
{\hyperlink{toc}{\beamergotobutton{Voltar ao início}}};
\end{tikzpicture}%
}%
}
\title{Apresentação RLZ}
\author{RLZ}
\date{\today}
\begin{document}
\begin{frame}
\titlepage
\end{frame}
\begin{frame}[label=toc]
\tableofcontents
\end{frame}
\AddButton
\section{Test Section}
\begin{frame} test frame \thepage \end{frame}
\begin{frame} test frame \thepage \end{frame}
\begin{frame} test frame \thepage \end{frame}
\end{document}
Here's one possibility; the idea is to define a command (\AddButton in my code) that oncludes the button as a part of the footline template used by the Boadilla theme; simply issue the command at the point where the button must be included in all successive frames (you can change the position of the button by changing the lengths used in the lines marked % HERE in my code):
\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage[brazil]{babel}
\usetheme{Boadilla}
\makeatletter
\newcommand\AddButton{%
\setbeamertemplate{footline}
{
\leavevmode%
\vskip-15pt% HERE
\hskip1em\hyperlink{toc}{\beamergotobutton{Voltar ao início}}% HERE
\vskip5pt% HERE
\hbox{%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
\usebeamerfont{author in head/foot}\insertshortauthor\expandafter\beamer@ifempty\expandafter{\beamer@shortinstitute}{}{~~(\insertshortinstitute)}
\end{beamercolorbox}%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
\usebeamerfont{title in head/foot}\insertshorttitle
\end{beamercolorbox}%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
\usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}
\insertframenumber{} / \inserttotalframenumber\hspace*{2ex}
\end{beamercolorbox}}%
\vskip0pt%
}%
}

You could try the
allowframebreaksoptionIt is for stuff like ToC or references.
