General ⇒ Making formated frame equal to source frame using LTXexample

[yoyoimut]

Dear all,

I am using showexpl package.

If the attribute "frame" is enabled (frame=single) then the frame enclosing code becomes larger than the frame enclosing the formated text.

However, when I disable it, both frames have the same size.
Please see my screen shot below.

I want to enable the frame such that both frames are equal to the text width.
Do you have any idea to do this?

\end{LTXexample}
\Marker

\section{Frame is disabled}
\Marker
\begin{LTXexample}[frame=none]
frame is disabled.
