# How to NOT report overfull hboxes from a personal command?

I create a command to display some symbol in the right margins in a twoside document. The point is that they always bring an overfull hbox warning in my logs whereas it obfuscates the real overfull hboxes.

So I want these false/expected warning NOT to be reported, since there are hundreds of them as I use this command hundreds of times.

Here is the MWE

    \documentclass[10pt,, twoside, a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage{blindtext}
\usepackage{showframe}

\newlength{\widthtxt}
%\setlength\widthtxt{0cm}
\setlength\widthtxt{\textwidth}

\newcommand{\qq}{%
\marginpar[{\hspace*{\widthtxt}\makebox[0pt][c]{$\oplus$}}]{%
\hspace*{-0.5\marginparsep}%
\makebox[0pt][c]{$\oplus$}%
}
}

\begin{document}

iueriuwe
\qq

\blindtext[5]

werrewew
\qq

\end{document}

• What exactly are you attempting with that \marginpar[{\hspace*{\widthtxt}\makebox[0pt][c]{$\oplus$}}].... why not just ask \marginpar to go on the other side if that is what you want? – daleif Jun 16 '15 at 11:02

Make the oversized box in a zero width box:

\newcommand{\qq}{%
\marginpar[%
{\makebox[0pt][l]{\hspace*{\largeurtexte}\makebox[0pt][c]{$\oplus$}}}%
]{%
\hspace*{-0.5\marginparsep}%
\makebox[0pt][c]{$\oplus$}%
}%
}


Here is a simpler version of the macros (I assume that \marginparsep is wider than the \oplus symbol). Less computations, as you see.

\documentclass[10pt, twoside, a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage{blindtext}
\usepackage{showframe}

\newcommand{\qq}{%
\marginpar[{% the brace for being able to use brackets
\hfill % push the material to the right boundary of the margin par region
\makebox[0pt][l]{% no width
\hspace*{\marginparsep}% go to the left boundary of the text block
\hspace*{\textwidth}% go to the right boundary of the text block
\makebox[\marginparsep]{$\oplus$}%
}%
}]{%
\hspace*{-\marginparsep}% go to the right boundary of the text block
\makebox[\marginparsep]{$\oplus$}%
}%
}

\begin{document}

iueriuwe\qq

\blindtext[5]

werrewew\qq

\end{document}

• it works well indeed. My code uses \makebox[0pt] on both sides and so I already have zero width boxes for both sides of the document. So how can they bring overfull hboxes ? – Carlos Jun 16 '15 at 11:32
• I forgot to put @egreg to contact you in the comment above – Carlos Jun 16 '15 at 17:01
• @Carlos You had inner zero width boxes, but you had \hspace*{\widthtxt} that made the \marginpar very wide. – egreg Jun 16 '15 at 17:03
