beamer 上的 RTL 目录

Question

我用了这个答案与标题框相关大小，但如果我添加，这会导致目录居中或对齐\flushright。此代码部分解决了该问题，但抑制了编号项目符号（图 1）：

\setbeamertemplate{section in toc}{%
\setRTL {\inserttocsectionnumber}
 \inserttocsection\par
}

如何正确对齐此 RTL（图 2）：

Answer 1

您可以添加\raggedleft到section in toc模板：

% !TeX TS-program = xelatex

\documentclass{beamer}

\useinnertheme[shadow=true]{rounded}

\usepackage{fontspec}
\usepackage{polyglossia}
\setdefaultlanguage[numerals=maghrib, calendar=gregorian]{arabic}
\setotherlanguage{english}
\newfontfamily\arabicfont[Script=Arabic]{Arial}
\newfontfamily\arabicfontsf[Script=Arabic]{Arial}
\newfontfamily\arabicfonttt[Script=Arabic]{Arial}
\newfontfamily\amiri[Script=Arabic]{Arial}

\makeatletter
\defbeamertemplate{section in toc}{myball}{
\leavevmode\leftskip=2.75ex%
  \llap{%
    \normalsize%
    \begin{pgfpicture}{-1ex}{-0.7ex}{1ex}{1ex}
      \pgftext{\beamer@usesphere{section number projected}{tocsphere}}
      \pgftext{%
        \usebeamerfont*{section number projected}%
        \usebeamercolor{section number projected}%
        \color{fg!90!bg}%
        \inserttocsectionnumber}
    \end{pgfpicture}%
    \kern1.25ex}%
    \raggedleft \inserttocsection\par
}
[action]
{\setbeamerfont{section number projected}{size=\scriptsize}}

\defbeamertemplate{subsection in toc}{myball}
{\leavevmode\leftskip=5ex%
  \llap{\raise0.1ex\beamer@usesphere{subsection number projected}{bigsphere}\kern1ex}%
  \raggedleft \inserttocsubsection\par%
}


\setbeamertemplate{sections/subsections in toc}[myball]
\makeatother
