脚注在区块中的放置不当

根据 的主题beamer-document，脚注将放置在块环境内部或外部。它希望结合一种样式，将脚注放置在里面Copenhagen例如带有脚注的块环境 外部块。奇怪的是，我尝试过的选项\setbeamertemplate{blocks}[option]似乎都没有做到这一点 - 无论我是否使用了default, circles, rectangles,或inmargin。还有其他方法可以告诉 beamer 脚注应该放在框架的底部吗？

在左侧，您可以看到使用主题的期望结果Berlin，两个脚注都在框架的底部。在右侧，您可以看到使用主题的结果，Copenhagen不幸的是，它将一个脚注放在了块环境中，我希望避免这种情况。

更新 24.02。

我发现beamerbaseboxes.sty这个 minipage 似乎负责块环境里面的脚注。

\newcommand\beamerboxesrounded[2][]{%
  [...]
  % line 120
  \setbox\bmb@box=\hbox\bgroup\begin{minipage}[b]{\bmb@width}%
  \vskip2pt%
  \usebeamercolor[fg]{\bmb@lower}%
  \colorlet{beamerstructure}{upper.bg}%
  \colorlet{structure}{upper.bg}%
  %\color{.}%
}

\def\endbeamerboxesrounded{%
  \end{minipage}\egroup%

但是删除小页面并不是一个好的解决方案，因为它会打乱布局。此外，将\end{minipage}\egroup%脚注\newcommand\beamerboxesrounded放在幻灯片底部，但会打乱布局。

这个问题和这个

您需要\footnotemark在block环境内部并使用\foocitetext{reese}：

\begin{frame}{A frame}
  \begin{block}{Classic theory}
    As we already know from classic theory\footnotemark, ...
    \begin{itemize}
      \item Fact 1
      \item Fact 2
    \end{itemize}
  \end{block}\footcitetext{reese}
Now there are some new developments\footcite{bertram} challenging the classic view.
\end{frame}

根据您的具体风格，可以将这个基本思想融入其中。这里使用etoolbox 包中的钩子\sfcite设置块外的脚注。\AfterEndEnvironment

如果你愿意手动跟踪脚注，最好采用更简单的方法。添加仅有的序言中的内容如下：

\makeatletter
\renewcommand\@makefnmark{\hbox{\@textsuperscript{\normalfont[\@thefnmark]}}}
\renewcommand\@makefntext[1]{{\normalfont[\@thefnmark]}\enspace #1}
\makeatother

\DeclareCiteCommand{\footfullcitetext}[\mkbibfootnotetext]
  {\usebibmacro{prenote}}
  {\usedriver
     {\DeclareNameAlias{sortname}{default}}
     {\thefield{entrytype}}}
  {\multicitedelim}
  {\usebibmacro{postnote}}

然后输入你的框架作为

\begin{frame}{A frame}
  \begin{block}{Classic theory}
    As we already know from classic theory\footnotemark\ ...
    \begin{itemize}
      \item Fact 1
      \item Fact 2
    \end{itemize}
  \end{block}\footfullcitetext{reese}

Now there are some new developments\footfullcite{bertram} challenging the classic view. 
\end{frame}
