[Tex/LaTex] How to get extra subtitles for chapter titles that also appear in the ToC

chapterssectioningtable of contents

I have several chapter titles that I would like to combine with subtitles, typeset in italics.

For example,

Chapter Title

A very fine chapter indeed …

Now, I found an approach on how to do this here, introducing a new \Chapter command, which now looks like this:

\newcommand\Chapter[2]{
  \chapter[#1: {\itshape#2}]{#1\\[2ex]\Large\itshape#2}
}

This somewhat works (although it breaks TextMate's auto-recognition of chapters), but I would like these subtitles to also be visible in the Table of Contents.

Like so:

Chapter Title 1

A very fine chapter indeed …

Is there any way to achieve that? Note that my LaTeX fu is pretty limited, so I'm not sure where to even start.

This simple solution should work for you. It is not formatted as you wished, but I really cannot imagine a ToC with subtitles below some title there.

\documentclass{report}

\newcommand\Chapter[2]{
  \chapter[#1: {\itshape#2}]{#1\\[2ex]\Large\itshape#2}
}

\begin{document}

\tableofcontents

\Chapter{My chapter}{Nice subtitle}

Lorem ipsum ...

\chapter{Another chapter}

Lorem ipsum ...

\end{document}

Alternative definition of \Chapter to have the subtitle below the title in ToC:

\newcommand\Chapter[2]{\chapter
  [#1\hfil\hbox{}\protect\linebreak{\itshape#2}]%
  {#1\\[2ex]\Large\itshape#2}%
}

Partial answer, because I was lately trying something similar. Updated with @speravir’s suggestions and two ugly solutions of putting \dictum between prefixed chapter number and chapter title.

\documentclass[
  headings=big,
  chapterprefix=true%% like in standard class "report"
]{scrreprt}
%\usepackage[T1]{fontenc}%% pdflatex
\usepackage{fontspec}%% xelatex
\usepackage{xcolor}
\usepackage{graphicx}

%% partial TOCs after chapter title
\usepackage[]{minitoc}
\setcounter{secnumdepth}{3} % number subsubsections
\setcounter{tocdepth}{3} % list subsubsections
\mtcsetdepth{minitoc}{2}% ~ \setcounter{minitocdepth}{2}
\mtcsetfont{minitoc}{*}{\usekomafont{chapterentry}}
\mtcsetfont{minitoc}{section}{\usekomafont{chapterentry}\bfseries} 
\mtcsetfont{minitoc}{subsection}{\usekomafont{chapterentry}} 
\mtcsettitle{minitoc}{\relax}% remove “Contents”
\mtcsetoffset{minitoc}{-3.5em}% don’t know the appropriate length
\mtcsetrules{minitoc}{off}
\mtcsetpagenumbers{minitoc}{on}% default anyway
%\mtcsetfeature{minitoc}{before|after|open|close|pagestyle}{command} 

%% layout of chapter title by @Speravir
\addtokomafont{chapterprefix}{\raggedleft}
\renewcommand*{\chapterformat}{%
\mbox{\chapappifchapterprefix{\nobreakspace}%
\scalebox{5}{\color{gray}\thechapter\autodot}\enskip}%
}

%% put dictum between chapter number (with prefix) and title
%% \setdictum[⟨source⟩]{⟨quote⟩} -- before \chapter
\iftrue % change to \iffalse to test different approach
%% hacky approach
\newcommand\getdictum{\relax}
\newcommand\setdictum[2][]{\renewcommand\getdictum{\dictum[#1]{#2}}}
\usepackage{etoolbox}
\makeatletter
%% \patchcmd{⟨command⟩}{⟨search⟩}{⟨replace⟩}{⟨success⟩}{⟨failure⟩}
\patchcmd{\@@makechapterhead}{\size@chapterprefix{}}{\size@chapterprefix{}{\vskip 1em\getdictum}}{}{}
\makeatother
\else
% 
\newcommand\setdictum[2][]{%
  \setchapterpreamble[ol][0.5\textwidth]{\vskip 5em\dictum[#1]{#2}}%
}
\fi

\begin{document}
\dominitoc
\faketableofcontents

\setcounter{chapter}{6}\setcounter{page}{199}

\setdictum[Sun Tzu]{If you know the enemy and you know yourself %\\
you need not fear the results of a hundred battles.}
\chapter{Conclusions}

[Tex/LaTex] How to get subtitles for chapter titles to appear in the ToC, but not in the page headers

Here is a suggestion using \markboth

\newcommand\Chapter[2]{\chapter
  [#1\hfil\hbox{}\protect\linebreak{\itshape#2}]%
  {#1\\[2ex]\Large\itshape#2}%
  \markboth{\MakeUppercase{\chaptername\ \thechapter.\ #1}}{}%
}

enter image description here

Code:

\documentclass{book}
\usepackage{lmodern}

\newcommand\Chapter[2]{\chapter
  [#1\hfil\hbox{}\protect\linebreak{\itshape#2}]%
  {#1\\[2ex]\Large\itshape#2}%
  \markboth{\MakeUppercase{\chaptername\ \thechapter.\ #1}}{}%
}

\usepackage{blindtext}
\begin{document}
\tableofcontents
\Chapter{Title}{Subtitle}
\blindtext[10]
\end{document}

There is another possibility: try a KOMA-Script class with the class option

headings=optiontoheadandtoc

Then the extended interpretation of the optional argument is activated and you can use

\newcommand\Chapter[2]{\chapter[
    tocentry={#1\hfil\hbox{}\protect\linebreak{\itshape#2}},
    head={#1}
  ]{#1\\[2ex]\Large\itshape#2}%
}

enter image description here

Code:

\documentclass[headings=optiontoheadandtoc]{scrbook}
\usepackage{lmodern}

\newcommand\Chapter[2]{\chapter[
    tocentry={#1\hfil\hbox{}\protect\linebreak{\itshape#2}},
    head={#1}
  ]{#1\\[2ex]\Large\itshape#2}%
}

\usepackage{blindtext}
\begin{document}
\tableofcontents
\Chapter{Title}{Subtitle}
\blindtext[10]
\end{document}

Chapter Title

Chapter Title 1
