My question is similar to following one: Table of Contents: Nice Titles for Parts
However, the solution didn't help me enough to resolve my problem.
My question is: In the Table Of Content, I have a title holding on two line, and I need to have the second line of my title indented of .25inch from the first line.
The definition of \l@part in the TOC definition of the package I use is the following:
\newcommand\l@part[2]{%
\ifnum \c@tocdepth >-2\relax
\addpenalty{-\@highpenalty}%
\addvspace{2.25em \@plus\p@}%
\begingroup
\setlength\@tempdima{3em}%
\parindent \z@ \rightskip \@pnumwidth
\parfillskip -\@pnumwidth
{\leavevmode
\bfseries #1\hfil \hbox to\@pnumwidth{\hss #2}}\par
\nobreak
\global\@nobreaktrue
\everypar{\global\@nobreakfalse\everypar{}}
\endgroup
\fi}
I tried to add the following before \nobreak:
\advance\leftskip\@tempdima% NEW: comment out if no indentation required for lines 2,3,...
I'm sure that I'm missing a small thing to make everything work, but I can't figure it out. Also, I don't think this solution would work since I need to specify the space of .25''.
The solution given seems to only indent the second line as much as the first line. So I added \hspace{.25in} after \leftskip but it didn't work neither.
Thank you.
