Framed boxes and listings

Hi all

For a presentation I would like to create framed code blocks using the
great listings package. With delightment I noticed that the
environments provided by listings work in almost every case. It
triggered only one case where things didn't work as expected.

History: Framed boxes in LaTeX suck when used on low-resolution
devices such as projectors. The piecewise assembly using ruleboxes and
other stuff I don't even want to think about, causes rounding errors
which is a pain in the eye. No matter whether anti-aliased diaplay is
used or not. Each way is equally bad, although in different respects.
Antialiased display suffers mostly from different line thickness,
while a normal display has overshoots in most corners of a box.

Given that I use PDF output only, my goal is to use a "native"
frame. I got excellent results from putting the listing into a
rectangular node. Since that seemed a bit to baroque I tried stripping
down the solution to using a framed `tikzpicture' and \pgftext with my
`lstlisting' as argument. Somehow, in the latter case, PGF did not get
the bounding box of the environment right.

My two questions are now:

1. What did I miss. What is the Right Way to achieve what I want?

2. Why does it not work with \pgftext? Was I completely off-track?

3. Ideally I'd have a solution that wraps all that into a new
environment. Potential users don't want to bother with PGF/TikZ just

Using PGF/TikZ to create framed environments (was: Framed boxes and listings)

OK, so my original subject was silly and appeared to be off-topic.

Re: Using PGF/TikZ to create framed environments

Ping! Does anyone have an idea how to tackle that sort of issue?

If putting it inside a node works, you could always hide the
"baroqueness" inside a custom macro or environment. Nodes are very
flexible and you can easily add shadows and other eye candy if you
want to (see for instance
http://www.fauskes.net/pgftikzexamples/tag/text-and-math/).

Users who use Beamer for presentations, also have PGF and TikZ
installed. The problem will be users with old versions of PGF.
