[Tex/LaTex] How to insert space in the short title and slide number in the footline of beamer

beamerheader-footer

I am using Warsaw theme. There is no space in the short title and slide number in the footline of my beamer presentation.

This is my MWE:

\documentclass{beamer}
\mode<presentation>{\usetheme{Warsaw}}
%% preamble
\title[]{\sc}

\makeatletter
\setbeamertemplate{footline}{%
\leavevmode%
\hbox{\begin{beamercolorbox}[wd=.24 \paperwidth,ht=2.5ex,dp=1.125ex,leftskip=.01cm plus1fill,rightskip=.05cm]{author in head/foot}%
            \usebeamerfont{title in head/foot}\insertshortauthor
    \end{beamercolorbox}%
    \begin{beamercolorbox}[wd=.76\paperwidth,ht=2.5ex,dp=1.125ex,leftskip=.05cm,rightskip=.15cm plus1fil]{title in head/foot}%
        \usebeamerfont{title in head/foot}\insertshorttitle
        \insertframenumber{} / \inserttotalframenumber \ \hspace*{2ex} 
    \end{beamercolorbox}}%
    \vskip0pt%
}
\makeatother

\begin{document}
\begin{frame}
Hello World!
\end{frame}
\end{document}

Best Answer

Commands that just print a text normally make the following space(s) disappear (see Space after LaTeX commands for example).

In order to prevent this you can use (1) \command{} (2) \command\ (space after \) or (3) use the xspace package (if you create your own commands). The list is not complete I guess.

Short Solution

\insertshorttitle{}

Complete Code

\documentclass{beamer}
\mode<presentation>{\usetheme{Warsaw}}
%% preamble
\title[Short Title]{Long Title}

\makeatletter
\setbeamertemplate{footline}{%
\leavevmode%
\hbox{\begin{beamercolorbox}[wd=.24 \paperwidth,ht=2.5ex,dp=1.125ex,leftskip=.01cm plus1fill,rightskip=.05cm]{author in head/foot}%
            \usebeamerfont{title in head/foot}\insertshortauthor
    \end{beamercolorbox}%
    \begin{beamercolorbox}[wd=.76\paperwidth,ht=2.5ex,dp=1.125ex,leftskip=.05cm,rightskip=.15cm plus1fil]{title in head/foot}%
        \usebeamerfont{title in head/foot}\insertshorttitle{}
        \insertframenumber{} / \inserttotalframenumber \ \hspace*{2ex} 
    \end{beamercolorbox}}%
    \vskip0pt%
}
\makeatother

\begin{document}
\begin{frame}
Hello World!
\end{frame}

[Tex/LaTex] How to insert text into the footline of a specific slide in Beamer

This provides a new template/font/color footline extra and a macro \footlineextra to add text to the footline.

\documentclass{beamer}    
\title{Adding extra text to footline}
\author{R.J.~Drofnats}
\institute{University of St. Anford}

\useoutertheme{infolines}% for example, ymmv

\makeatletter
% add a macro that saves its argument
\newcommand{\footlineextra}[1]{\gdef\insertfootlineextra{#1}}
\newbox\footlineextrabox

% add a beamer template that sets the saved argument in a box.
% The * means that the beamer font and color "footline extra" are automatically added. 
\defbeamertemplate*{footline extra}{default}{
    \begin{beamercolorbox}[ht=2.25ex,dp=1ex,leftskip=\Gm@lmargin]{footline extra}
    \insertfootlineextra
    %\par\vspace{2.5pt}
    \end{beamercolorbox}
}

\addtobeamertemplate{footline}{%
    % set the box with the extra footline material but make it add no vertical space
    \setbox\footlineextrabox=\vbox{\usebeamertemplate*{footline extra}}
    \vskip -\ht\footlineextrabox
    \vskip -\dp\footlineextrabox
    \box\footlineextrabox%
}
{}

% patch \begin{frame} to reset the footline extra material
\let\beamer@original@frame=\frame
\def\frame{\gdef\insertfootlineextra{}\beamer@original@frame}
\footlineextra{}
\makeatother


\setbeamercolor{footline extra}{fg=structure.fg}% for instance


\begin{document}

\begin{frame}\maketitle\end{frame}

\begin{frame}{foo}
\begin{itemize}
\item one
\item two
\item three
\end{itemize}
\footlineextra{Source: ``Mr. Lee'' by the Bobbettes}
\end{frame}

\begin{frame}{bar}
\begin{itemize}
\item Able
\item Baker
\item Charlie
\end{itemize}
\footlineextra{Source: \emph{What do People Do All Day?} by Richard Scarry}
\end{frame}

\begin{frame}{baz}
No footlineextra here
\end{frame}

\end{document}

Having spent an hour on this I must quit but a nice addition would be to make \footlineextra overlay-specification aware.

[Tex/LaTex] How to remove footline on the title page of beamer slides

You can redefine footline locally for the title frame; I also modified the framenumber counter so that the frames including the footline start from one:

\documentclass{beamer}

\useoutertheme{infolines}
\setbeamertemplate{footline}{\hspace*{.5cm}\scriptsize{\insertshorttitle
\hspace*{50pt} \hfill\insertframenumber\hspace*{.5cm}}\\
\vspace{9pt}}

\title{The Title}

\begin{document}

{
\setbeamertemplate{footline}{} 
\begin{frame}
  \titlepage
\end{frame}
}
\addtocounter{framenumber}{-1}

\begin{frame}
A frame with footline
\end{frame}
