Hi all,
I want to align the code's frame with the formated text's frame.
If the numbers=left,the mission is accomplished by configuring xleftmargin, xrightmargin, framesep, and numbersep.
However, when I set numbers=none, I cannot accomplish my mission by configuring those properties. Regardless of the values set to those properties, the code's frame remains unchanged and expands beyond the \textwidth.
Please see my code snippet below.
Thank you in advance.
\documentclass[a4paper,11pt,twoside,final,dvips]{book}
\usepackage{xcolor}
\usepackage{showexpl}
\lstset{%
 breaklines=true,
  breakindent=0pt,
 basicstyle=\color{magenta}\ttfamily\tiny, 
 keywordstyle=\color{blue}\sffamily\bfseries,
 identifierstyle=\color{black},
 commentstyle=\color{cyan}\itshape,
 stringstyle=\rmfamily,
 showstringspaces=false, 
 tabsize=2,
 %========== FRAME ========== 
 frame=single, 
 framerule=0.4pt, 
 rulecolor=\color{red},
 framesep=3pt, 
 %========== MARGIN ==========

 xrightmargin=3.4pt,

 explpreset={language={[LaTeX]TeX},pos=b}%
}
