[Tex/LaTex] moderncv – how to adjust the description columns

moderncv

So basically the question is in the title. How can I adjust the width of the part where I put info about myself? Currently it looks like this:

What my cv looks like now

You see how there is weird looking break. How can I extend it so that it expands to certain width? Or so that it fits in one line?

Ok, here's the MWE that's producing the same problem:

\documentclass[11pt,a4paper]{moderncv}
\moderncvtheme[green]{classic}                

% character encoding
\usepackage[utf8x]{inputenc}
\usepackage[croatian]{babel}
\usepackage{ucs}                   % replace by the encoding you are using

% adjust the page margins
\usepackage[scale=0.8]{geometry}
%\setlength{\hintscolumnwidth}{3cm}                     % if you want to change the width of the column with the dates
%\AtBeginDocument{\setlength{\maketitlenamewidth}{6cm}}  % only for the classic theme, if you want to change the width of your name placeholder (to leave more space for your address details
%\AtBeginDocument{\recomputelengths}                     % required when changes are made to page layout lengths

% personal data
\firstname{John}
\familyname{Doe}
%\title{Resumé title (optional)}               % optional, remove the line if not wanted

\homepage{http://www.somepage.com}                % optional, remove the line if not wanted
%\extrainfo{additional information (optional)} % optional, remove the line if not wanted
%\photo[64pt]{picture}                         % '64pt' is the height the picture must be resized to and 'picture' is the name of the picture file; optional, remove the line if not wanted
%\quote{Some quote (optional)}                 % optional, remove the line if not wanted

Best Answer

This is because of the way \cvcomputer is defined. From cvmodern.cls:

% usage (inside 'computer skills' cvsection environment): \cvcomputer{category}{programs}{category}{programs}
\newcommand*{\cvcomputer}[4]{%
  \cvdoubleitem{#1}{\small#2}{#3}{\small#4}}

So let's see how \cvdoubleitem is defined:

% usage: \cvdoubleitem{subtitle}{text}{subtitle}{text}
\newcommand*{\cvdoubleitem}[4]{%
 \cvline{#1}{\begin{minipage}[t]{\doubleitemmaincolumnwidth}#2\end{minipage}%
 \hfill%
 \begin{minipage}[t]{\hintscolumnwidth}\raggedleft\hintfont{#3}\end{minipage}\hspace*{\separatorcolumnwidth}\begin{minipage}[t]{\doubleitemmaincolumnwidth}#4\end{minipage}}}

While I didn't bother to understand all of this, the minipages and a look at the CTAN template tells me that this type of entry is geared toward a two-column layout, presumably because the author assumed computer entries won't be very long.

If you don't want the two-column layout, I recommend redefining \cvcomputer like this:

\renewcommand{\cvcomputer}[2]{\cvline{#1}{\small#2}}

Make sure you remove the third and fourth arguments, which are empty, from your source. Your section would be like this:

\renewcommand{\cvcomputer}[2]{\cvline{#1}{\small#2}}
\section{Računalne vještine}
\cvcomputer{Operativni sustavi}{Windows, UNIX(Linux), izvrsno poznavanje rada operativnih sustava}
\cvcomputer{Programiranje}{Osnove rada u Phythonu}
\cvcomputer{WEB dizajn}{HTML}
\cvcomputer{Office paketi}{Znanje rada s Wordom, Excellom, Powerpointom}
\cvcomputer{Adobe}{Poznavanje rada s Adobe Photoshopom, Illustratorom i InDesignom}
\cvcomputer{Hardware}{PC, mreže}

BUT, why not make use of the two-column layout? Then, don't use the redefinition and just reorder the arguments:

\section{Računalne vještine}
\cvcomputer{Operativni sustavi}{Windows, UNIX(Linux), izvrsno poznavanje rada operativnih sustava}{Office paketi}{Znanje rada s Wordom, Excellom, Powerpointom}
\cvcomputer{Programiranje}{Osnove rada u Phythonu}{Adobe}{Poznavanje rada s Adobe Photoshopom, Illustratorom i InDesignom}
\cvcomputer{WEB dizajn}{HTML}{Hardware}{PC, mreže}
