大都會主題中自訂框架標題中的進度條

Question

使用這beamer回答 我已將我的大學徽標添加到使用該主題製作的幻燈片的框架標題中Metropolis。微量元素：

\documentclass[9pt,aspectratio=169,]{beamer}
\usetheme[progressbar=frametitle,
subsectionpage=progressbar,
block=fill]{Metropolis}
\usepackage[export]{adjustbox}

\makeatletter
\setlength{\metropolis@frametitle@padding}{1.8ex}% <- default 2.2 ex
\setbeamertemplate{frametitle}{%
    \nointerlineskip%
    \begin{beamercolorbox}[%
        wd=\paperwidth,%
        sep=0pt,%
        leftskip=\metropolis@frametitle@padding,%
        rightskip=\metropolis@frametitle@padding,%
        ]{frametitle}%
        \metropolis@frametitlestrut@start%
        \insertframetitle%
        \nolinebreak%
        \metropolis@frametitlestrut@end%
        \hfill
        \includegraphics[height=3ex,keepaspectratio,valign=c]{example-image}
    \end{beamercolorbox}
}

\begin{document}

\begin{frame}
\frametitle{Frame title}
Contents...
\end{frame}

\end{document}

但現在我的框架標題下方不再有進度條了。我嘗試使用大都會的程式碼將其添加回來手動的，但沒有成功。任何幫助表示讚賞。謝謝！

Answer 1

您可以\usebeamertemplate*{progress bar in head/foot}在自訂框架標題定義的末尾新增：

\documentclass[9pt,aspectratio=169,]{beamer}
\usetheme[progressbar=frametitle,
subsectionpage=progressbar,
]{moloch}% modern fork of the metropolis theme
\usepackage[export]{adjustbox}

\makeatletter
\setlength{\moloch@frametitle@padding}{1.8ex}% <- default 2.2 ex
\setbeamertemplate{frametitle}{%
    \nointerlineskip%
    \begin{beamercolorbox}[%
        wd=\paperwidth,%
        sep=0pt,%
        leftskip=\moloch@frametitle@padding,%
        rightskip=\moloch@frametitle@padding,%
        ]{frametitle}%
        \moloch@frametitlestrut@start%
        \insertframetitle%
        \nolinebreak%
        \moloch@frametitlestrut@end%
        \hfill
        \includegraphics[height=3ex,keepaspectratio,valign=c]{example-image}
    \end{beamercolorbox}
    \usebeamertemplate*{progress bar in head/foot}
}

\setlength{\moloch@progressinheadfoot@linewidth}{3pt}% just to better see that it's working
