[Tex/LaTex] beamer: Footnote in columns Environment | Indention Too Short

beamercolumnsfootnotes

  • I often use the columns environment in beamer frames.
  • When I have a long footnote within a column then the indention after the line break is very short.
  • Am I doing it right?
  • How can I enlarge the indention?
\documentclass[t]{beamer}

\begin{document}

\begin{frame}
%
\frametitle{Title of Frame}
    \begin{columns}[t]
        %
        \begin{column}{.50\textwidth}
        \begin{itemize}
        \item Text Text\footnote{Long Footnote Text Long Footnote Text Long Footnote Text Long Footnote Text Long Footnote Text} Text.
        \item Text Text Text.
        \end{itemize}
        \end{column}
        %
        \begin{column}{.50\textwidth}
        \end{column}
        %
    \end{columns}

Playing with your MWE, I discovered that columns doesn't really handle footnotes (doesn't force them to keep the column size and also causes the problem of your question)

This is the way I found that it works better:

\documentclass[t]{beamer}

\begin{document}

\begin{frame}
%
\frametitle{Title of Frame}

    \begin{columns}[t]
        %
        \begin{column}{.50\textwidth}
        \begin{itemize}
        \item Text Text Text.\footnotemark[1]
        \end{itemize}
        \end{column}
        %
        \begin{column}{.50\textwidth}
        \begin{itemize}
        \item Text Text Text.
        \item Text Text\footnotemark[2]
        \end{itemize}
        \end{column}

    \end{columns}
        %
\footnotetext[1]{This is one: Long Footnote Text Long Footnote Text Long Footnote Text Long Footnote Text Long Footnote Text}
\footnotetext[2]{This is Two: Long Footnote Text Long Footnote Text Long Footnote Text Long Footnote Text Long Footnote Text}
\end{frame}
\end{document}

If you want separate footnote place for each column, this answer doesn't help you... And may be I can try for another way... But it is ok for my taste.

Output:

PS: may be we have to reduce a little bit from 0.5 (but I am not sure if columns use a inner or outer sep... so didn't do it yet)

Edit A fix but with not original indent of footnote:

I created the footcolumn to be used when footnotes are included instead of the original:

\documentclass[t]{beamer}
\usepackage{adjustbox}
\let\oldfootnotetext\footnotetext
\newsavebox{\mybox}
\def\footnote#1{\footnotemark[1]\oldfootnotetext[1]{\adjustbox{valign=t}{\begin{minipage}[b]{0.9\textwidth}#1\end{minipage}}}}

\newenvironment{footcolumn}
{\begin{column}}{\end{column}\hspace{-0.5\textwidth}}

\begin{document}

\begin{frame}
%
\frametitle{Title of Frame}

    \begin{columns}[t]
        %
        \begin{footcolumn}{.50\textwidth}
        \begin{itemize}
        \item Text TextText.\footnote{This is one: Long Footnote Text Long Footnote Text Long Footnote Text Long Footnote Text Long Footnote Text}
        \end{itemize}
        \end{footcolumn}
        %
        \begin{footcolumn}{.50\textwidth}
        \begin{itemize}
        \item Text Text Text.
        \item Text Text\footnote{This is two: Long Footnote Text Long Footnote Text Long Footnote Text Long Footnote Text Long Footnote Text}
        \end{itemize}
        \end{footcolumn}

    \end{columns}
        %
\end{frame}
\begin{frame}
%
\frametitle{Title of Frame}

    \begin{columns}[t]
        %
        \begin{footcolumn}{.50\textwidth}
        \begin{itemize}
        \item Test
        \item Text TextText.\footnote{This is one: Long Footnote Text Long Footnote Text Long Footnote Text Long Footnote Text Long Footnote Text}
        \end{itemize}
        \end{footcolumn}
        %
        \begin{column}{.50\textwidth}
        \begin{itemize}
        \item Text Text Text.
        \item Text Text
        \end{itemize}
        \end{column}

    \end{columns}
        %
\end{frame}
\end{document}

You can combine it with the original without problems (even as last column will work ok!). It is not perfect, because of the non indented start.. But Closer I think.

Last Edit before remove previous:

(Fixed some indent)

\documentclass[t]{beamer}
\usepackage{adjustbox}
\let\oldfootnotetext\footnotetext
\newdimen\myindent
\myindent=2mm
\newcounter{myfootnote}
\makeatletter
\def\footnote{\stepcounter{myfootnote}\xdef\themyfootnote{\arabic{myfootnote}}\@ifnextchar[{\readFootnoteNum}{\readFootnote}}
\def\readFootnoteNum[#1]{\footnotemark[#1]\xdef\themyfootnote{#1}\addtocounter{myfootnote}{-1}\readFootnote}
\def\readFootnote#1{\oldfootnotetext{\adjustbox{valign=t}{\begin{minipage}[b]{0.86\textwidth}\hspace{\myindent}$^{\themyfootnote}$#1\end{minipage}}}}
\makeatother

\newenvironment{footcolumn}
{\begin{column}}{\end{column}\hspace{\dimexpr-0.5\textwidth+\myindent}}
