\parbox vs. minipage: Differences in applicability
The main reason I see to use minipage
over \parbox
is to allow verbatim (\verb
, verbatim
, etc.) text inside the box (unless, of course, you also put the minipage
inside a macro argument).
EDIT Here are other differences between minipage
and \parbox
(from the comments to Yiannis' answer and from looking at the source code of both these macros in source2e).
A first difference, as already mentioned by lockstep in his question, is in the footnote treatment: minipage
handles them by putting them at the bottom of the box while footnotes are lost in a \parbox
(to avoid this, you must resort to the \footnotemark
/footnotetext
trick):
\documentclass{article}
\begin{document}
\parbox[t]{3cm}{text\footnote{parbox footnote}}
\begin{minipage}[t]{3cm}text\footnote{minipage footnote}\end{minipage}
\end{document}
A second difference is in that minipage
resets the \@listdepth
counter, meaning that, inside a minipage
, you don't have to worry about the list
nesting level when using them. Here's an example which illustrates the point:
\documentclass{article}
\begin{document}
\begin{list}{}{}\item\begin{list}{}{}\item\begin{list}{}{}\item\begin{list}{}{}\item
\begin{list}{}{}\item\begin{list}{}{}
\item %\parbox{5cm}{\begin{list}{}{}\item \end{list}}% error
\item %\begin{minipage}{5cm}\begin{list}{}{}\item \end{list}\end{minipage}% no error
\end{list}\end{list}\end{list}\end{list}\end{list}\end{list}
\end{document}
A third difference is that minipage
sets the boolean \@minipagefalse
which in turn deactivates \addvspace
if it's the first thing to occur inside a minipage
. This means that minipage
will have better spacing and allow better alignment compared to \parbox
in some cases like the following (left is minipage
, right is \parbox
):
\documentclass{article}
\begin{document}
Pros: \begin{minipage}[t]{3cm}\begin{itemize}\item first \item second%
\end{itemize}\end{minipage}
Cons: \parbox[t]{3cm}{\begin{itemize}\item first \item second\end{itemize}}
\end{document}
When your text you wish to enclose contains only a small piece of text then use \parbox
. It should have nothing fancy inside such as any of the paragraph making environments. For larger pieces of text, such as those that do contain paragraph-making environments you should use a minipage
environment.
There are also more subtle differences between the two such as the amount of space left on top etc. In general a minipage
acts like a full page, whereas a parbox
acts more like a fancy paragraph. Both of them offer very little semantic meaning - in my opinion. You can add semantic meaning by creating new environments with macro names that reflect their function in the document structure. For example you could define one of those boxes that one finds in manuals with a framed warning, a warning box
using parbox
and call it warning
.
If you make a new environment, you must enclose the body of the environment using lrbox
first, then use the saved box in \parbox
. But if you use minipage instead of \parbox
, lrbox
is no longer needed.
