How can I insert a newline in a framebox?

Question

I have several frameboxes in my document, using the following command:

\framebox(115,115){ R-Sq: \newline For example} 

I want to force a new line, but neither \newline or \\ appear to work. Is there any other way of doing this?

Answer 1

TH. has suggested putting the framebox around another box, but specifying the size can be awkward. Here's my (note: plug) solution to the problem:

\usepackage{minibox}
...
\minibox[frame]{R-Sq:\\ For example}

A ‘minibox’ is exactly equivalent to a tabular in the current implementation; I just wanted the shorter markup.

Answer 2

At the risk of beating a dead horse, I find the framed package works most convenient.

\usepackage{framed}
\begin{framed}
   My long text that needs new lines.
\end{framed}

You need not worry about sizing--line breaks are automatic. It works well with the beamer class too.

Answer 3

If you dig through the chain of macro expansions, you see that \framebox(x,y)[z]{text} ends up typesetting text in an \hbox.

So you can use this.

\documentclass{article}
\begin{document}
\framebox(115,115){%
    \parbox{115\unitlength}{R-Sq:\\For example}%
}
\end{document}

Where all I've done is put the input inside an appropriately sized \parbox.

Answer 4

\documentclass{article}
\usepackage[usestackEOL]{stackengine}
\begin{document}
\framebox{\Longstack[l]{This\\is\\a\\test}}
\framebox{\Longstack[c]{This\\is\\a\\test}}
\framebox{\Longstack[r]{This\\is\\a\\test}}
\end{document} 

Answer 5

@celenius One way to insert a newline in a framed box using \\ (\newline itself does not work with this method), using just the amsmath package and without defining a parbox, is to use boxed with array. For example:

\documentclass[11pt]{article}
\usepackage{amsmath}
\begin{document}
\boxed{
\begin{array}{clr}
\textrm{short line}\\
\textrm{long line containing a relatively large number of characters}\\
\textrm{short line again}
\end{array}}
\end{document}

Answer 6

Put a minipage into a framebox:

\documentclass[a4paper,12pt]{article}
\begin{document}
some text
\noindent
\framebox[\textwidth]  % width of the framebox
{
\begin{minipage}{0.9\textwidth}  % width of the minipage
first line
second line 
\end{minipage}
}
some text 
\end{document}

Answer 7

it works fine

\framebox{
    \parbox{\columnwidth-4\fboxsep}{sample text sample text sample text sample text sample text sample text sample text sample text sample text sample text sample text sample text sample text sample text sample text }
}
