Section titles alignement with titletoc

Question

with the following code

\documentclass{book}
\usepackage[T1]{fontenc}
\usepackage[english]{babel}
\usepackage{titletoc}

\titlecontents{chapter}
[0em]
{\vspace*{\baselineskip}}
{\mdseries \contentslabel[\thecontentspage] {0mm}  \hspace*{1.4em}  \chaptername 
\,\,\thecontentslabel \\
\hspace*{2em} \itshape    \vspace*{0.3\baselineskip}}
{\mdseries   \thecontentspage \hspace*{1.2em}   \itshape}
{}
[]

\titlecontents*{section}
[0em]
{}
{\footnotesize \thecontentslabel~}
{}
{\footnotesize,~\thecontentspage}
[~--\ ]
[]

\begin{document}

\tableofcontents

\chapter{Events and Probability}
\section{Composite Events}
\section{Composite Events}
\section{An Application of Composite Events}
\section{Probability}
\section{The Probability of an Unknown Constant}
\section{A Confirmation}

\setcounter{page}{277}

\chapter*{Conclusion}
\addcontentsline{toc}{chapter}{Conclusion}

\end{document}

how can I align the left left margin of sections titles with the chapter title? I'm able to line up with an eye, but obviously it's a very bad idea... thanx

PS

Now I realize another problem. The starred chapter is not aligned with the other titles. why?

PS2

i add an image of that I'd like to obtain

the page margins and the index margins are different. Why? Index is narrower as page.... You can see it in the picture under

If I add a starred chapter to the ToC with \addcontentsline{toc}{chapter}{Conclusion} they look aligned... Can you please expand your MWE so that it shows the misalignment? — Phelype Oleinik, Oct 16 '18 at 13:07
I updated code, recompiled. same problem, as in the figure above — user41063, Oct 16 '18 at 13:20

You had some spurious spaces in your \titlecontents definition, for example:

\hspace*{1.4em} \chaptername

produces a larger space than

\hspace*{1.4em}\chaptername

You also was using \contentslabel incorrectly. This macro reserves some space to the left of the margin for the label. But form your picture I assumed you didn't want it, so I removed and used a plain \hbox with \llap. I also added the \part formatting from your other question:

ok, thanx! I corrected my mistakes. your code solve the second problem, but sections titles are yet not aligned to left left margin of sections titles, as in my forst aid request – user41063 Oct 16 '18 at 13:59
@user41063 Oops, I forgot that. Hold on – Phelype Oleinik Oct 16 '18 at 14:01
@user41063 Just to clarify: you want it exactly as in the picture you just uploaded? – Phelype Oleinik Oct 16 '18 at 14:04
centered part title (already solved), sections under chapter title, as in the picture – user41063 Oct 16 '18 at 14:08
@user41063 I think it's correct now. – Phelype Oleinik Oct 16 '18 at 14:18
a last thing: after the part title (I'd like to have it without page number), in the following line, there ia an orfan page number – user41063 Oct 16 '18 at 14:26
@user41063 Ooh, that page number is only because of the red line. I used \addcontentsline{toc}{chapter}{\protect\tikz... to draw the red line in the correct position. Once you remove that line, the number will disappear. – Phelype Oleinik Oct 16 '18 at 14:29
perfect, thanx a lot! – user41063 Oct 16 '18 at 15:15
a little problem more with margins. see the above code and picture plz – user41063 Oct 16 '18 at 17:20
@user41063 Sorry the delay, I was in class. I edited the answer. Adding \contentsmargin[-1.55em]{1.55em} should solve the issue. – Phelype Oleinik Oct 16 '18 at 19:36
yes, now all perfectly working. but plz explain me... why 1.55em? where comes that lenght from? – user41063 Oct 16 '18 at 20:11
@user41063 It's the default value of \@pnumwith defined in the book class. You can change it at your will, but make sure that it's large enough to fit the page number (\@pnumwidth is short for page number width), and make sure that both values are equal, so that with your layout the margins are aligned. – Phelype Oleinik Oct 16 '18 at 20:21
ok. now all's perfectly working. thanx for your competence and kindness – user41063 Oct 16 '18 at 20:31
