答案1
这里的问题是，您在 TikZ 中设置了部分标题\node，默认情况下这是一个不允许换行的框，它将变得与节点的内容一样宽。要解决此问题，请text width为设定一个node，这将导致节点文本在超出该宽度时中断。
您可能还想更改其中的anchor，node或者如果它需要多行，您可能最终会将部分章节标题放在您绘制的线下方。
一个简单的例子：
\documentclass{scrartcl}
\usepackage{titlesec}
\usepackage{tikz}
\usetikzlibrary{calc,positioning}
\newcommand\boxedSectionB[3]{{%
\begin{tikzpicture}[inner sep=#3,line width=1pt]
\node[anchor=east,rectangle,draw,fill=black] at (0,0) (counter) {\color{white}\textbf{#2}};
\draw (counter.south west) ++(.0pt,.5pt)-- ++($(\linewidth,0) - (2.5pt,0)$);
\node [right=of counter.south east, % bottom right corner of box with section number
anchor=south west, % bottom left corner of section title box
text width=.7\linewidth] % Change the width to whatever you want
{#1};
\end{tikzpicture}
}}
\newcommand\boxedsection[1]{\boxedSectionB{#1}{\thesection}{2mm}}
\titleformat{\section}[hang]%
{\usekomafont{section}}%
{}%
{.0em}%
{\filright\boxedsection}%
\begin{document}
\section{try try try try try try try try try try try try try try try try try try try try try try try try try try try try try try}
