Calligraphic fonts for chapters,

Question

I'm currently using calligraphic font and it works fine with 1 exception: Chapter/Section and title aren't affected by it. How can it be made that they too can be affected (and if its a general way how can it be done that the title is not affected but chapters and sections)?

\documentclass[10pt,a4paper,BCOR10mm,DIV11,toc=listof,parskip=full, openany]{scrbook}
\usepackage{etoolbox}
\usepackage{xpatch}
\makeatletter
\renewcommand{\chapterheadstartvskip}{\vspace{0pt}}
\renewcommand{\chapterheadendvskip}{\vspace{\baselineskip}}
\patchcmd{\section}{-3.5ex \@plus -1ex \@minus -.2ex}{-\z@}{}{} 
\patchcmd{\section}{2.3ex \@plus .2ex}{1sp}{}{} 
\patchcmd{\subsection}{-3.25ex\@plus -1ex \@minus -.2ex}{-\z@}{}{}
\patchcmd{\subsection}{1.5ex \@plus .2ex}{1sp}{}{}
\patchcmd{\subsubsection}{-3.25ex\@plus -1ex \@minus -.2ex}{-\z@}{}{}
\patchcmd{\subsubsection}{1.5ex \@plus .2ex}{1sp}{}{}
\patchcmd{\@xsect}{\ignorespaces}{\vspace*{-.5\baselineskip}\ignorespaces}{}{}


\xpatchcmd{\maketitle}{\if@twoside\next@tpage}{\iffalse}{}{}

\makeatother

Answer 1

This is because KOMA-script issues a separate font selection to set chapter titles. Specifically, \sectfont, which defaults to

\newcommand*{\sectfont}{\normalcolor\sffamily\bfseries}

Changing this to

\renewcommand*{\sectfont}{\normalcolor\usefont{T1}{pzc}{m}{it}}

produces the desired output:
