Part title in list of figures and tables?

Question

I'm using KOMAScript. I have a \listoffigures and a \listoftables. My document has several \part{}'s. In the two lists the figures and tables are already grouped (small vertical space) by the chapters.

What I'd like to have additionally to the ("anonymous") chapter vspace grouping is the part title over each "part group" of figures and tables in the two lists. Is this somehow possible without having to code a list from scratch?

Answer 1

You can setup your own entry by:

\newcommand{\addtocentrylistof}[3]{%
  \ifstr{#2}{}{%
    \addcontentsline{lof}{#1}{#3}%
    \addcontentsline{lot}{#1}{#3}%
  }{%
    \addcontentsline{lof}{#1}{\protect\numberline{#2}#3}%
    \addcontentsline{lot}{#1}{\protect\numberline{#2}#3}%
  }%
}

\renewcommand*{\addparttocentry}[2]{%
  \addtocentrydefault{part}{#1}{#2}%
  \addtocentrylistof{part}{#1}{#2}%
}

Here a small example:

\documentclass[english]{scrreprt}
\usepackage{babel}
\newcommand{\addtocentrylistof}[3]{%
  \ifstr{#2}{}{%
    \addcontentsline{lof}{#1}{#3}%
    \addcontentsline{lot}{#1}{#3}%
  }{%
    \addcontentsline{lof}{#1}{\protect\numberline{#2}#3}%
    \addcontentsline{lot}{#1}{\protect\numberline{#2}#3}%
  }%
}

\renewcommand*{\addparttocentry}[2]{%
  \addtocentrydefault{part}{#1}{#2}%
  \addtocentrylistof{part}{#1}{#2}%
}
\def\examplefig{\begin{figure}[!ht]\caption{foo}\end{figure}\begin{table}[!ht]\caption{foo}\end{table}}
\begin{document}
\tableofcontents
\listoffigures
\listoftables

\part{O I}
\chapter{foo}
\examplefig\examplefig\examplefig
\chapter{foo}
\examplefig\examplefig\examplefig
\chapter{foo}
\examplefig\examplefig\examplefig
\part{O II}
\chapter{bar}
\examplefig\examplefig\examplefig
\chapter{bar}
\examplefig\examplefig\examplefig
\chapter{bar}
\examplefig\examplefig\examplefig

\end{document}

Answer 2

This is just an adaptation from this answer to Include chapters in List of Figures with titletoc? . The inclusion is made automatically using the standard commands and only for the parts with figures:

\documentclass{scrreprt}
\usepackage{etoolbox} % or xpatch

\makeatletter
% initial definitions of the chapter info (name and number)
\def\thischaptertitle{}\def\thischapternumber{}
\newtoggle{noFigs}
\newtoggle{noTabs}

\apptocmd{\@part}%
  {\gdef\thisparttitle{#1}\gdef\thispartnumber{\thepart}%
    \global\toggletrue{noFigs}\global\toggletrue{noTabs}}{}{}

% the figure environment does the job: the first time it is used after a \chapter command, 
% it writes the information of the chapter to the LoF
\AtBeginDocument{%
  \AtBeginEnvironment{figure}{%
    \iftoggle{noFigs}{
      \addtocontents{lof}{\protect\contentsline {part}%
        {\protect\numberline {\thispartnumber} {\thisparttitle}}{}{} }
      \global\togglefalse{noFigs}
    }{}
  }%
  \AtBeginEnvironment{table}{%
    \iftoggle{noTabs}{
      \addtocontents{lot}{\protect\contentsline {part}%
        {\protect\numberline {\thispartnumber} {\thisparttitle}}{}{} }
      \global\togglefalse{noTabs}
    }{}
  }%
}

\makeatother
