更改 Beamer 中超链接边框的形状

Question

我正在尝试将 Beamer 演示文稿中超链接的边框从圆角改为矩形（块可以做到这一点）。我还不知道该怎么做，但似乎应该很简单。有什么想法吗？

\documentclass{beamer}

\begin{document}

\begin{frame}{The title}
\label{thelabel}
\hyperlink{thelabel}{\beamerbutton{thetext}}
\end{frame}

\end{document}

Answer 1

我不知道是否有内置方法可以做到这一点，但您可以简单地定义按钮以适合您的口味。

\documentclass{beamer}

\makeatletter
\setbeamertemplate{button}{%
    \setbox\beamer@tempbox=\hbox{{\insertbuttontext}}%
    \ht\beamer@tempbox=6pt%
    \dp\beamer@tempbox=0pt%
    \setbox\beamer@tempbox=\vbox{\box\beamer@tempbox\vskip2pt}%
    \beamer@tempdim=\wd\beamer@tempbox%
    \beamer@dima=\beamer@tempdim\advance\beamer@dima by2.2pt
    \beamer@dimb=\beamer@tempdim\advance\beamer@dimb by4pt
    \begin{pgfpicture}{-2pt}{0pt}{\the\beamer@tempdim}{8pt}
        \usebeamercolor[bg]{button frame}
        \pgfpathrectangle{\pgfpointorigin}{\pgfpoint{\beamer@dimb}{8pt}}
        \pgfusepath{fill}
    \end{pgfpicture}%
    \hskip2pt
    \hskip-\beamer@tempdim%
    \box\beamer@tempbox%
    \kern4pt%
}
\makeatother

\begin{document}

    \begin{frame}{The title}
        \label{thelabel}
        \hyperlink{thelabel}{\beamerbutton{thetext}}
    \end{frame}

\end{document}
