Beamer 中一種奇特而美麗的枚舉類型

Question

我正在嘗試重現這篇文章的枚舉環境（一種奇特而美麗的枚舉類型） 在投影儀。我的 MWE 是根據那裡改編的，如下：

\documentclass{beamer}

\usepackage{tikz}
\newcommand{\Colorlist}{red,blue,green,yellow}
\newcommand{\SebastianoItem}[1]{\foreach \X[count=\Y] in \Colorlist
{\ifnum\Y=#1\relax
\xdef\SebastianoColor{\X}
\fi
}
\tikz[baseline=(SebastianoItem.base),remember
picture]{%
\node[fill=\SebastianoColor,inner sep=4pt,font=\sffamily,fill opacity=0.5] (SebastianoItem){#1)};}
}
\newcommand{\SebastianoHighlight}{\tikz[overlay,remember picture]{%
\fill[\SebastianoColor,fill opacity=0.5] ([yshift=4pt,xshift=-\pgflinewidth]SebastianoItem.east) -- ++(4pt,-4pt)
-- ++(-4pt,-4pt) -- cycle;
}}

\begin{document}
\begin{frame}
\renewcommand{\labelenumi}{\SebastianoItem{\arabic{enumi}}}

Some general advices.
  \begin{enumerate}
    \item No fast food.
    \item Don't drink to much alcohol.
    \item No pineapple on pizza. \SebastianoHighlight
    \item Don't use onions in food.
  \end{enumerate}

\end{frame}
\end{document}

當我取消註解 \renewcommand 和 \SebastianoHighlight 行時，程式碼會編譯，所以我猜錯誤就在那裡。我知道在 Beamer 中更新命令比在 Article 文檔類中更棘手。但是，我找不到解決方案。有任何想法嗎？

Answer 1

在投影機中：

\setbeamertemplate{enumerate item}{\SebastianoItem{\arabic{enumi}}}

同樣對於列舉子項,列舉子子項，並列舉迷你模板。

\documentclass{beamer}

\usepackage{tikz}
\newcommand{\Colorlist}{red,blue,green,yellow}
\newcommand{\SebastianoItem}[1]{\foreach \X[count=\Y] in \Colorlist
{\ifnum\Y=#1\relax
\xdef\SebastianoColor{\X}
\fi
}
\tikz[baseline=(SebastianoItem.base),remember
picture]{%
\node[fill=\SebastianoColor,inner sep=4pt,font=\sffamily,fill opacity=0.5] (SebastianoItem){#1)};}
}
\newcommand{\SebastianoHighlight}{\tikz[overlay,remember picture]{%
\fill[\SebastianoColor,fill opacity=0.5] ([yshift=4pt,xshift=-\pgflinewidth]SebastianoItem.east) -- ++(4pt,-4pt)
-- ++(-4pt,-4pt) -- cycle;
}}

\setbeamertemplate{enumerate item}{\SebastianoItem{\arabic{enumi}}}


\begin{document}
\begin{frame}
%\renewcommand{\labelenumi}{\SebastianoItem{\arabic{enumi}}}

Some general advices.
  \begin{enumerate}
    \item No fast food.
    \item Don't drink to much alcohol.
    \item No pineapple on pizza. \SebastianoHighlight
    \item Don't use onions in food.
  \end{enumerate}

\end{frame}
\end{document}
