sectioningtitlesec
I'd like the section title to look just as it does by default, except the following changes:
I've tried to use the titlesec package as done in the firt answer to the following question:
How to place a shaded box around a section label and name
However, I'm really having a hard time getting things to work with titlesec (it's not so intuitive in it's settings for me).
This is relatively easy to achieve using the titlesec package:
\documentclass{scrbook}
\usepackage{tikz,titlesec}
\usepackage[english]{babel}
\usepackage{blindtext} % for a test document
\titleformat{\section}[block]%
{\usekomafont{sectioning}\usekomafont{section}%
\tikz[overlay] \shade[left color=blue!20,right color=white] (0,-1ex) rectangle (\textwidth,1em);}%
{\thesection}%
{1em}%
{}
\begin{document}
\blinddocument
\end{document}
Note the following:
\usekomafont{sectioning}\usekomafont{section} sets the font to whatever is chosen using the KOMA Script styling mechanism.
The [overlay] option of \tikz means that TikZ won't take any space.
This breaks if the title is longer than a line.
Edit: Here is second version, that works with long lines and does not ignore ascenders and descenders. The code is more complicated, though. It draws the whole section heading with TikZ.
\documentclass{scrbook}
\usepackage{tikz,titlesec}
\usetikzlibrary{calc}
\pgfdeclarelayer{background}
\pgfsetlayers{background,main}
\newcommand\boxedsection[1]{{%
\usekomafont{sectioning}\usekomafont{section}%
\begin{tikzpicture}[inner sep=0pt, inner ysep=0.3ex]
\node[anchor=base west] at (0,0) (counter) {\thesection};
\path let \p1 = (counter.base east) in node[anchor=base west, text width={\textwidth-\x1-0.33em}] (content) at ($(counter.base east)+(0.33em,0)$) {#1};
\begin{pgfonlayer}{background}
\shade[left color=blue!20,right color=white] let \p1=(counter.north), \p2=(content.north) in
(0,{max(\y1,\y2)}) rectangle (content.south east);
\end{pgfonlayer}
\end{tikzpicture}%
}}
\titleformat{\section}%
{}%
{}%
{0pt}%
{\boxedsection}%
\begin{document}
\chapter{test}
\section{Overview}
\section{Implementation}
\section{a very long section entry a very long section entry a very long section entry a very long section entry a very long section entry}
\end{document}
This is a very interesting layout. Try the following code. A boolean is hooked to the \everypar. This means that if there is plain paragraph first it is set to false and the next subsection will have normal spacing. Note also the strange place where the \secskip command end up, but it seems to work.
EDIT 1: Restore original \everypar and remove vertical space of \lastskip before moving subsection up. Remove all glue and add \raggedbottom to prevent stretching.
EDIT 2: It looks if the additional vertical spacing is \baselineskip
\usepackage{titlesec}
\makeatletter
\newif\ifaftersec\aftersecfalse
\newcommand\setsubskip{%
\global\aftersectrue
\everypar{%
\global\aftersecfalse
\if@noskipsec
\global\@noskipsecfalse
\clubpenalty\@M
\hskip-\parindent
\begingroup
\@svsechd\unskip{\hspace{\@tempskipb}}%
\endgroup
\else
\clubpenalty\@clubpenalty\everypar{}%
\fi}}
\newcommand\subskip{%
\ifaftersec
\removelastskip% EDIT 2
\vspace{-\baselineskip}% EDIT 2 ??????????????
\fi
\global\aftersecfalse}
\titleformat{\section}[leftmargin]{\raggedright\scshape}{}{0pt}{}[\setsubskip]
\titlespacing*{\section}{2.5cm}{2.5ex}{0.5cm}
\titleformat{\subsection}{\subskip\bfseries}{}{0pt}{}[]
\titlespacing*{\subsection}{0pt}{2ex}{1ex}
\raggedbottom
\makeatother

Here is a solution
Update if we need some vertical space before and after
