tcolorbox 框标题中的换行符

Question

我有一个类似于以下的文档：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{blindtext}
\usepackage[most]{tcolorbox}

\newtcolorbox{definition}[2][]{
    arc=5mm,
    lower separated=false,
    fonttitle=\bfseries,
    colbacktitle=green!10,
    coltitle=green!50!black,
    enhanced,
    attach boxed title to top left={xshift=0.5cm,
            yshift=-3mm},
    colframe=green!50!black,
    colback=green!10,
    title=#2}

\begin{document}
\begin{definition}{Assume we have a title that is waaaaaaay too long to fit in a single line and therefore requires a line break}
\blindtext
\end{definition}
\end{document}

如您所见，标题太长，无法写成一行。如何在方框标题内创建换行符？我尝试使用\\，但不起作用。

Answer 1

作为一种解决方法，您可以将标题放在\parbox相应大小中：

\documentclass{article}
\usepackage{blindtext}
\usepackage[most]{tcolorbox}

\newtcolorbox{definition}[2][]{
    arc=5mm,
    lower separated=false,
    fonttitle=\bfseries,
    colbacktitle=green!10,
    coltitle=green!50!black,
    enhanced,
    attach boxed title to top left={xshift=0.5cm,
            yshift=-3mm},
    colframe=green!50!black,
    colback=green!10,
    title=#2}

\begin{document}

\begin{definition}{\parbox{10.45cm}{Assume we have a title that is waaaaaaay too long to fit in a single line and therefore requires a line break}}
\blindtext
\end{definition}

\end{document} 

Answer 2

tcolorbox为长标题定义了几种解决方案：minipage boxed title，，varwidth boxed title。tikznode boxed title

以下是第一个示例：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{blindtext}
\usepackage[most]{tcolorbox}

\newtcolorbox{definition}[2][]{
    arc=5mm,
    lower separated=false,
    fonttitle=\bfseries,
    colbacktitle=green!10,
    coltitle=green!50!black,
    enhanced,
    minipage boxed title*=-3cm,
    attach boxed title to top left={xshift=.5cm, yshift*=-\tcboxedtitleheight/2},
    colframe=green!50!black,
    colback=green!10,
    title=#2}

\begin{document}
\begin{definition}{Assume we have a title that is waaaaaaay too long to fit in a single line and therefore requires a line break}
\blindtext
\end{definition}
\end{document}
