如何更改特定定理环境的块模板(LaTeX beamer)

如所见 beamerbasetheorems.sty :

\documentclass[notheorems]{beamer}

\theoremstyle{plain}
\newtheorem{theorem}{\translate{Theorem}}
\newtheorem{example}[theorem]{\translate{Example}}

% or

\theoremstyle{definition}
\newtheorem{theorem}{\translate{Theorem}}
\newtheorem{example}[theorem]{\translate{Example}}

% or

\theoremstyle{example}
\newtheorem{theorem}{\translate{Theorem}}
\newtheorem{example}[theorem]{\translate{Example}}

不管你喜欢什么款式。您还可以更改[alert | example]块的外观:

\setbeamercolor{block body}{fg=blue,bg=white}
\setbeamercolor{block body alerted}{fg=blue,bg=white}
\setbeamercolor{block body example}{fg=blue,bg=white}

编辑: 仍然不确定您想要做什么,但您可以定义自己的定理样式:

\makeatletter
\def\th@something{%
  \normalfont % body font
  \def\inserttheoremblockenv{alertblock}  
}
\theoremstyle{something}
\newtheorem{warn}[theorem]{WARNING}
\makeatother

\begin{warn}[Attention please]
This is dangerous
\end{warn}

您有3个预定义的块,可以使用\defbeamertemplate进行自定义。查看有关如何执行此操作的源代码和文档。如果需要更多块环境,请参阅 basebeamerlocalstructure.sty

  \newenvironment<>{alertblock}[1]{%
    \begin{actionenv}#2%
      \def\insertblocktitle{#1}%
      \par%
      \mode<presentation>{%\usebeamerfont{block}%
        \setbeamercolor{local structure}{parent=alerted text}}%
      \usebeamertemplate{block alerted begin}}
    {\par%
      \usebeamertemplate{block alerted end}%
    \end{actionenv}}
