Help me, please to make the style of "Contents" heading to be as \chapter{Le choix du thème}.

Also I would like to put all headings a little bit higher and to fix the hyperref for "Contents" in pdf

Thank you.

Answer 1

You didn't provide a mimimal example, but by stripping down your code, I was at least able to fix the most serious problem, i.e. the ToC title not obeying the formatting of other chapter titles (e.g. not being centered). The reason for this is that by loading the tocloft package you disabled the influence of titlesec on the table of contents. Use the macros provided by tocloft instead. (I didn't bother to delve into your hyperref problems, as hyperref and titlesec also don't go together well.)

EDIT: hyperref problem solved. Your rather non-standard way of redefining \thechapter created two chapters numbered with 1 (although the number was hidden in case of the Introduction), and this confused hyperref. Solution: Set the chapter counter to -1 before the Introduction, which will then become chapter 0.

\documentclass[12pt]{report} 

\usepackage[utf8]{inputenc}

\usepackage{titlesec}

\titleformat{\chapter}[display]
    {\Huge\bfseries\centering}{\chaptertitlename\ \thechapter}{5pt}{\Large}
\titlespacing*{\chapter}{0pt}{30pt}{20pt}
\titleformat{\section}
    {\bfseries}{\thesection}{1em}{}

\usepackage{tocloft}

\renewcommand\cftchappresnum{\chaptername\newline}
\setlength{\cftchapnumwidth}{3.5cm}

% These redefinitions were missing
\renewcommand{\cfttoctitlefont}{\hfill\Large\bfseries}
\renewcommand{\cftaftertoctitle}{\hfill}
\setlength{\cftbeforetoctitleskip}{30pt}
\setlength{\cftaftertoctitleskip}{20pt}

\usepackage{hyperref}

\end{thebibliography}

\end{document}

Answer 2

You simply need to redefine \contentsname. The babel package does this automatically for the selected language (for latex/pdflatex). The polyglossia package seems to do the same for XeLaTeX. Because this happens at the \begin{document} you need to redefine it afterwards. At best directly before it.

\renewcommand{\contentsname}{Le choix du thème}
\tableofcontents

Answer 3

You can use \renewcommand*\contentsname{new name} like suggested in a thread on LaTeX community. Notice that the thread also recommends against that solution.

To turn the table of contents into a chapter use:

\makeatletter
\renewcommand\tableofcontents{%
        \chapter{\contentsname
        \@mkboth{%
           \MakeUppercase\contentsname}{\MakeUppercase\contentsname}}%
        \@starttoc{toc}%
        }
\makeatother

I think there is a better solution though. This seems dirty.
