[Gabriele Zucchetta]

Hi,
I need to obtain this

center to the page, and I use:

\begin{center}
\fbox{
Text text text.
}\end{center}

But I have 2 questions:

1) Why this form don't works:

\fbox{\begin{center}Text text text.\end{center}}

2) I need to define this whit new environment. I have tried this:

\newenvironment{mycenterbox}{\fbox{\begin{center}}{\end{center}}}


and this is similar to the example that I have found in the
facybox.sty manual (pag. 3), but this not work, why?

First because \fbox can only contain horizontal material (= one line
not more). Second because even if it would work it would center the
text _in_ the box and not the box itself.

It isn't similar to an example in the fancybox manual.

First fancybox use a minipage inside the \fbox-command (minipages are
boxes, while center are not),

Second the manual says clearly that the example is an example you
_can't_ use! It has unbalanced braces in its argument, so it doesn't
work. Look at the following pages to learn how you can do it.

fair enough.

because it talks about centring text inside the \fbox, which isn't
what you want to do (and isn't allowed, either).

it's not similar to the example in the manual: as near as makes no
difference, it's the same as your question (1) which doesn't do the
job and falls foul of a check for this sort of error in latex.

the fancybox example works because it's putting the stuff in a
minipage (which is a box, itself); once the minipage is complete, its
contents get \fbox'ed.

you could either do the same (adding \begin{center} before \fbox and
after \end{minipage}, in the example, or you could to the standard

\newsavebox{\zzz}
\newenvironment{mycenterbox}{\begin{lrbox}{\zzz}}%
{\end{lrbox}\fbox{\usebox{\zzz}}}

\newsavebox{\zzz}
\newenvironment{mycenterbox}{\begin{lrbox}{\zzz}}%
{\end{lrbox}\fbox{\usebox{\zzz}}}

but that omits the actual centring. that is left as an exercise for
the reader ...

This doesn't properly deal with nesting, but it should give you the idea.
