tcolorbox`内部标题代码应用程序`不起作用

这是我的 MWE：

\documentclass{article}
\usepackage{tcolorbox}
\usepackage{lipsum}
\tcbuselibrary{skins,hooks}

\newtcolorbox{mybox}[2][]{enhanced,
frame code app={\draw[yellow,line width=1cm] (frame.south west)--(frame.north east);},
interior titled code app={\draw[red,line width=1cm] (frame.north west)--(frame.south east);},
leftrule=3mm,
arc=4mm,
colframe=blue!80!red,colback=white,colbacktitle=blue!5!yellow!50!white,
fonttitle=\bfseries,coltitle=black,
attach boxed title to top center={yshift=-0.25mm-\tcboxedtitleheight/2,yshifttext=2mm-\tcboxedtitleheight/2},
boxed title style={enhanced,boxrule=.5mm,frame code={ \path[tcb fill frame] ([xshift=-4mm]frame.west)-- (frame.north west) -- (frame.north east) -- ([xshift=4mm]frame.east)-- (frame.south east) -- (frame.south west) -- cycle; },interior code={ \path[tcb fill interior] ([xshift=-2mm]interior.west) -- (interior.north west) -- (interior.north east)-- ([xshift=2mm]interior.east) -- (interior.south east) -- (interior.south west) -- cycle;}  },
title={#2},#1}


\newtcolorbox{mybox2}[2][]{enhanced,
    frame code app={\draw[yellow,line width=1cm] (frame.south west)--(frame.north east);},
    interior titled code app={\draw[red,line width=1cm] (frame.north west)--(frame.south east);},
    leftrule=3mm,
    arc=4mm,
    colframe=blue!80!red,colback=white,colbacktitle=blue!5!yellow!50!white,
    fonttitle=\bfseries,coltitle=black,
%   attach boxed title to top center={yshift=-0.25mm-\tcboxedtitleheight/2,yshifttext=2mm-\tcboxedtitleheight/2}, 
    boxed title style={enhanced,boxrule=.5mm,frame code={ \path[tcb fill frame] ([xshift=-4mm]frame.west)-- (frame.north west) -- (frame.north east) -- ([xshift=4mm]frame.east)-- (frame.south east) -- (frame.south west) -- cycle; },interior code={ \path[tcb fill interior] ([xshift=-2mm]interior.west) -- (interior.north west) -- (interior.north east)-- ([xshift=2mm]interior.east) -- (interior.south east) -- (interior.south west) -- cycle;}  },
    title={#2},#1}

\begin{document}

\begin{mybox}{Studied systems}
    \lipsum[1]  
\end{mybox}

\lipsum[1]
\begin{mybox2}{Studied systems2}
    \lipsum[1]  
\end{mybox2}

\end{document}

我也想让红线穿过第一个 tcolorbox。我发现attach boxed title to top center代码可以产生红线消失的效果。

这个问题的解决方案是什么？

答案1

和frame code app是interior titled code app相当低级的选项。interior titled code app添加用于绘制带有标题的框内部的代码。全部方框标题版本将标题从主框中分离出来，并将其放入自己的框中。这意味着，主框将被视为没有标题的框。因此，interior titled code app没有效果，因为它仅用于有标题的框（在低级意义上）。

一个可能的解决方案是替换interior titled code app为interior code app：

\documentclass{article}
\usepackage{tcolorbox}
\usepackage{lipsum}
\tcbuselibrary{skins,hooks}

\newtcolorbox{mybox}[2][]{enhanced,
  frame code app={\draw[yellow,line width=1cm] (frame.south west)--(frame.north east);},
  interior code app={\draw[red,line width=1cm] (frame.north west)--(frame.south east);},
  leftrule=3mm,
  arc=4mm,
  colframe=blue!80!red,colback=white,colbacktitle=blue!5!yellow!50!white,
  fonttitle=\bfseries,coltitle=black,
  attach boxed title to top center={yshift=-0.25mm-\tcboxedtitleheight/2,yshifttext=2mm-\tcboxedtitleheight/2},
  boxed title style={enhanced,boxrule=.5mm,frame code={ \path[tcb fill frame] ([xshift=-4mm]frame.west)-- (frame.north west) -- (frame.north east) -- ([xshift=4mm]frame.east)-- (frame.south east) -- (frame.south west) -- cycle; },interior code={ \path[tcb fill interior] ([xshift=-2mm]interior.west) -- (interior.north west) -- (interior.north east)-- ([xshift=2mm]interior.east) -- (interior.south east) -- (interior.south west) -- cycle;}  },
  title={#2},#1}

\begin{document}

\begin{mybox}{Studied systems}
    \lipsum[1]
\end{mybox}

\end{document}

或者，由于红线交叉点位于框顶部，您可以使用overlay或underlay选项，这些选项更高级且独立于标题设置。
