我正在使用 Beamer 打印讲义。在讲义中，我需要一张幻灯片来展示一个定理和它旁边的一个图。讲义中的所有定理都使用包进行着色阴影定理。
但这个包似乎不能很好地与 minipage 配合使用。我试图放弃使用这个包，而是使用框架包，但阴影框中文本前后的间距与使用 shadetheorem 包的不匹配。
如何将阴影定理放入小页面中？我宁愿坚持使用 shadetheorem 包，因为我有许多其他定义和定理依赖于这个包。

答案1
你不需要列环境。只需将两个小页面并排放置在阴影定理环境内即可。
\begin{frame}
\begin{THM_mini}
\begin{minipage}[c]{0.58\textwidth}
Here is a theorem. Here is an equation:
\[
E = m c^2.
\]
Here is a theorem.
\end{minipage}
\begin{minipage}[c]{0.4\textwidth}
\begin{tikzpicture}[>=latex', scale=0.9, every node/.style={scale=0.95}]
% x-axis
\draw[semithick,->] (-0.5, 0) -- (3.5, 0)
node[below] {$x\vphantom{b}$};
% y-axis
\draw[semithick, ->] (0, -0.5) -- (0, 3.5)
node[left] {$y$};
\end{tikzpicture}
\end{minipage}%
\end{THM_mini}
\end{frame}
编辑：
由于我最初误解了 OP，所以这是他想要的实际答案：要获得具有一半文本宽度的阴影定理环境，\shadedtextwidth必须在定义新的定理环境之前手动设置长度。
\setlength{\shadedtextwidth}{0.5\textwidth}
\newshadetheorem{THM_mini}{Theorem in Minipage.}
在这种情况下，小页面是没有必要的。
\begin{frame}
\begin{columns}[onlytextwidth]
\begin{column}[c]{0.50\textwidth}
\begin{THM_mini}
Here is a theorem. Here is an equation:
\[
E = m c^2.
\]
Here is a theorem.
\end{THM_mini}
\end{column}
\begin{column}[c]{0.50\textwidth}
\centering
\begin{tikzpicture}[>=latex', scale=0.9, every node/.style={scale=0.95}]
% x-axis
\draw[semithick,->] (-0.5, 0) -- (3.5, 0)
node[below] {$x\vphantom{b}$};
% y-axis
\draw[semithick, ->] (0, -0.5) -- (0, 3.5)
node[left] {$y$};
\end{tikzpicture}
\end{column}
\end{columns}
\end{frame}

再想想。第一个解决方案改变了所有阴影定理的宽度。这可能不是你想要的。也许一个简单的
\let\shadedtextwidth\textwidth
对您来说是一个更好的解决方案。这样，阴影定理的宽度始终是文本宽度。
