使用 titleformat 在 tikz 节点中限制标题

Question

我在章节标题中使用了一种相当花哨的风格，即

\documentclass[12pt,open=left]{scrbook}

\usepackage{tikz}
\usepackage{pgfplots}

\usepackage{titlesec}
\usepackage{titletoc}

\usepackage{scrpage2}\pagestyle{scrheadings}

\renewcommand{\chaptermark}[1]{ \markboth{#1}{}}

\titleformat{\chapter}
[hang]
{}
{}
{0em}
{\Large \bf
  \ifnum\value{chapter}>0
    \begin{tikzpicture} 
      \node[text width=2.55cm] (chapter) at (0,0) {Ch \thechapter \newline \newline}; 
      \draw [ultra thick] (chapter.north east) -- (chapter.south east);
    \end{tikzpicture}\hspace{0.5cm}
  \fi
\Huge}
[\ifnum\value{chapter}>0 
  \normalsize \vspace{-1.3cm} \hspace{2.85cm} 
  \tikz{
    \node[text width=10cm] (toc) at (0,0){
      \newline \newline \newline
      %\parindent=20em
      \begin{minipage}{12cm}
      %\parindent=20em
      \printcontents[c]{}{1}{}
      \end{minipage}
    }; 
    \draw [ultra thick] (toc.north west) -- (toc.south west);} 
\fi]


\usepackage{minitoc}

\begin{document}

\startcontents[c]
\chapter{Short chapter title}
\section{thats an arbitrary section}
\subsection{thats an arbitrary section}
\subsection{thats an arbitrary section}
\section{thats an arbitrary section}
\section{thats an arbitrary section}
\stopcontents[c]

\startcontents[c]
\chapter{Here appears a very long chapter title causing issues}
\section{thats an arbitrary section}
\subsection{thats an arbitrary section}
\subsection{thats an arbitrary section}
\section{thats an arbitrary section}
\section{thats an arbitrary section}
\stopcontents[c]

\end{document}

不幸的是，如果标题超过 2 行，我的风格就会被破坏。我希望标题的第二行与第一行从相同的位置开始，并且黑线没有间隙。

最简单的解决方案似乎是将标题限制在 tikz 节点中，一侧为黑色，但到目前为止我还没有找到可行的解决方案。

您需要explicit包选项，它可以让您指定文本的打印位置。

启用该选项后，您可以获得类似的效果：

\node [right,text width=12cm] at(chapter.south east){#1};

进入您的tikzpicture，其中#1设置文本位置。

梅威瑟：

\documentclass[12pt,open=left]{scrbook}

\usepackage{tikz}
\usepackage{pgfplots}

\usepackage[explicit]{titlesec}
\usepackage{titletoc}

\usepackage{scrpage2}\pagestyle{scrheadings}

\renewcommand{\chaptermark}[1]{ \markboth{#1}{}}

\titleformat{\chapter}
[hang]
{}
{}
{0em}
{\Large \bf
  \ifnum\value{chapter}>0
    \begin{tikzpicture}
      \node[text width=2.55cm] (chapter) at (0,0) {Ch \thechapter \newline \newline};
      \draw [ultra thick] (chapter.north east) -- (chapter.south east);
      \node [right,text width=12cm] at(chapter.south east){#1};
    \end{tikzpicture}\hspace{0.5cm}
  \fi
\Huge}
[\ifnum\value{chapter}>0
  \normalsize \vspace{-1.3cm} \hspace{2.85cm}
  \tikz{
    \node[text width=10cm] (toc) at (0,0){
      \newline \newline \newline
      %\parindent=20em
      \begin{minipage}{12cm}
      %\parindent=20em
      \printcontents[c]{}{1}{}
      \end{minipage}
    };
    \draw [ultra thick] (toc.north west) -- (toc.south west);}
\fi]


\usepackage{minitoc}

\begin{document}

\startcontents[c]
\chapter{Short chapter title}
\section{thats an arbitrary section}
\subsection{thats an arbitrary section}
\subsection{thats an arbitrary section}
\section{thats an arbitrary section}
\section{thats an arbitrary section}
\stopcontents[c]

\startcontents[c]
\chapter{Here appears a very long chapter title causing issues}
\section{thats an arbitrary section}
\subsection{thats an arbitrary section}
\subsection{thats an arbitrary section}
\section{thats an arbitrary section}
\section{thats an arbitrary section}
\stopcontents[c]

\end{document}

后：

您可以通过新的节点选项调整文本样式。
