代码清单的圆角

Question

是否可以将 tex 代码列表做成圆角？鉴于：

\documentclass[10pt]{article}
\usepackage[usenames,dvipsnames]{xcolor} %used for font color
\usepackage[utf8]{inputenc} %useful to type directly diacritic characters
\usepackage{listings}
\usepackage{tcolorbox}
\tcbuselibrary{listings}

\begin{document}

\definecolor{lbcolor}{rgb}{0.1,0.1,0.1}

\lstdefinestyle{mystyle}{
     basicstyle=\ttfamily\color{White},
     language=Java,
     tabsize=1,
     keywordstyle=\color{Red}\bf,
     showstringspaces=false,
     morekeywords={public, class}
 }

\newtcblisting{mylisting}{
      arc=0pt,
      top=0mm,
      bottom=0mm,
      left=0mm,
      right=0mm,
      boxrule=0pt,
      colback=black,
      listing only,
      listing options={style=mystyle},
      hbox
}

\begin{mylisting}
public class MyObject{

    public MyObject(){
        System.out.println("MyObject");
    }
}
\end{mylisting}

\end{document} 

我想制作一个圆角。此代码将包含在演示文稿中，虽然只是外观问题，但当您拥有漂亮的圆角和阴影时，它看起来会更有吸引力。可以在 Latex 中完成吗？

Answer 1

选项arc就是为此目的提供的。您已将其设置为0pt。更改其值以表示类似5mm（例如）。此外，您可以使用enhanced选项和skins库添加阴影tcolorbox。语法如下

shadow={<xshift>}{<yshift>}{<offset>}{<options>}

完整代码：

\documentclass[10pt]{article}
\usepackage[usenames,dvipsnames]{xcolor} %used for font color
\usepackage[utf8]{inputenc} %useful to type directly diacritic characters
\usepackage{listings}
\usepackage{tcolorbox}
\tcbuselibrary{listings,skins}        %%% skins needed for shadow

\begin{document}

\definecolor{lbcolor}{rgb}{0.1,0.1,0.1}

\lstdefinestyle{mystyle}{
     basicstyle=\ttfamily\color{White},
     language=Java,
     tabsize=1,
     keywordstyle=\color{Red}\bf,
     showstringspaces=false,
     morekeywords={public, class}
 }

\newtcblisting{mylisting}{
      enhanced,                             %%% needed for shadow
      arc=5mm,
      top=0mm,
      bottom=0mm,
      left=0mm,
      right=0mm,
      boxrule=0pt,
      colback=black,
      shadow={5mm}{-3mm}{0mm}{fill=black!50!white,
                      opacity=0.5},             %%% here for shadow  and adjust as you like
      listing only,
      listing options={style=mystyle},
      hbox
}

\begin{mylisting}
public class MyObject{

    public MyObject(){
        System.out.println("MyObject");
    }
}
\end{mylisting}

\end{document}

Answer 2

\documentclass{book}
\usepackage{listings}    
\lstset{frameshape={RYR}{Y}{Y}{RYR}}   
\begin{document}

\begin{lstlisting}[language=Python,breaklines,basicstyle=\footnotesize\ttfamily]{P04-Tk.py}
from tkinter import *                     # import Tkinter module

root = Tk()                               # create Tk root widget

root.mainloop()                           # enter Tkinter event loop
\end{lstlisting}

\end{document}

对于双线：\lstset{frameshape={ryrRYR}{yY}{yY}{ryrRYR}}
