失败的尝试

如何删除/更改主题.sty文件中某些幻灯片的页脚？
我基本上想避免\setbeamertemplate{footline}{}在我的幻灯片中使用.tex。例如在标题幻灯片/目录/部分幻灯片上...

失败的尝试

使用\newif

\newif\ifbeamer@test@title
\beamer@test@titlefalse

\defbeamertemplate*{title page}{test}{
  \beamer@test@titletrue
  <...>
  \beamer@test@titlefalse
}

\defbeamertemplate*{footline}{test}{
  \ifbeamer@test@title
  \else
    <...>
  \fi
}

最小工作示例

这里简化了 MWE，仅考虑了标题页，但该解决方案应该足够通用，以便也可以用于目录/部分幻灯片

cat beamerthemetest.sty

\mode<presentation>
%% goes to inner theme
\defbeamertemplate*{title page}{test}
{
    \beamer@test@titletrue
    {
      \vspace{42pt}
      \begin{beamercolorbox}{title}
        \usebeamerfont{title}\inserttitle
          \ifx\insertsubtitle\@empty
          \else
          \par\usebeamerfont{subtitle}\insertsubtitle
          \fi
      \end{beamercolorbox}
      \begin{beamercolorbox}{author}
        \usebeamerfont{author}\insertauthor
      \end{beamercolorbox}
  }
  \beamer@test@titlefalse
}

%% goes to outer theme

\defbeamertemplate*{footline}{test}
{
      \begin{beamercolorbox}[wd=\paperwidth, dp=1mm, ht=3.5mm
                             , leftskip=1mm, rightskip=1mm
                            ]{footline}%
        \usebeamerfont{title in head/foot}%

        \makebox[240pt][l]{
          \insertshorttitle\ - \insertsectionhead\ %
          \ifx\insertsubsectionhead\@empty\relax\else%
          - \insertsubsectionhead%
          \fi
          }
        \hfill\makebox[20pt][r]{\insertframenumber/\inserttotalframenumber}%
      \end{beamercolorbox}%
}

\mode<all>

与test.tex

\documentclass[aspectratio=169]{beamer}
\usetheme{test}
\author{whoami} 
\title{title}

\begin{document}
\maketitle

\section{abc}
\begin{frame}{abc}
cde
\end{frame} 
\end{document}

答案1

这似乎有效，但我并不确信这是最好的方法。

这.tex

\documentclass[aspectratio=169]{beamer}
\usetheme{test}
\author{whoami} 
\title{title}

\begin{document}

\newmaketitle

\section{abc}
\begin{frame}{abc}
cde
\end{frame} 
\section{def}
\begin{frame}{def}
fgf
\end{frame} 
\end{document}

这.sty

\mode<presentation>
%% goes to inner theme
\defbeamertemplate*{title page}{test}
{
    %\beamer@test@titletrue
    {
      \vspace{42pt}
      \begin{beamercolorbox}{title}
        \usebeamerfont{title}\inserttitle
          \ifx\insertsubtitle\@empty
          \else
          \par\usebeamerfont{subtitle}\insertsubtitle
          \fi
      \end{beamercolorbox}
      \begin{beamercolorbox}{author}
        \usebeamerfont{author}\insertauthor
      \end{beamercolorbox}
  }
}

\newcommand{\newmaketitle}{
  \setbeamertemplate{footline}[default]
  \begin{frame}
    \maketitle
  \end{frame}
  \setbeamertemplate{footline}[test]
}

%% goes to outer theme

\defbeamertemplate*{footline}{test}
{
      \begin{beamercolorbox}[wd=\paperwidth, dp=1mm, ht=3.5mm
                             , leftskip=1mm, rightskip=1mm
                            ]{footline}%
        \usebeamerfont{title in head/foot}%

        \makebox[240pt][l]{
          \insertshorttitle\ - \insertsectionhead\ %
          \ifx\insertsubsectionhead\@empty\relax\else%

          }
        \hfill\makebox[20pt][r]{\insertframenumber/\inserttotalframenumber}%
      \end{beamercolorbox}%

\AtBeginSection[]

    \addtocounter{framenumber}{-1}
  \begin{frame}{Outline}
    \tableofcontents
