Script KOMA: cambie la fuente de los subtítulos para un solo tipo de flotador

Question

Configuré un nuevo tipo de flotador. Usando el fontspecpaquete en scrreprt, ¿cómo cambio la fuente del título solo para ese tipo de flotador? En este momento, estoy usando \addtokomafont{caption}{\gillfont}y \addtokomafont{captionlabel}{\gillfont}(habiéndolo \gillfontespecificado antes). Esto, por supuesto, cambia la fuente de los títulos para todos los flotadores. ¿Cómo hago esto sólo para el nuevo textboxentorno?

MWE:

    \documentclass{scrreprt}
    \usepackage{lmodern}
    \usepackage[T1]{fontenc}
    \usepackage[english]{babel}

    %%%---being able to use all installed fonts (must compile with LuaLaTeX!)
    \usepackage{fontspec}
    \newfontfamily\gillfont{Gill Sans MT}

    %%%---setting up Box environment as float

    \usepackage{newfloat}
    \usepackage{caption}
    \DeclareFloatingEnvironment[fileext=frm,placement={H},name=Box]{myfloat}

    \captionsetup[myfloat]{labelfont=bf}

    \usepackage[framemethod=TikZ]{mdframed}

    \newenvironment{textbox}[1]
    {\begin{myfloat}[tb]
            \begin{mdframed}[backgroundcolor=gray!10]
                \caption{#1}
                            }
                {\end{mdframed}\end{myfloat}
    }

    %%%---formatting float captions

    \usepackage{chngcntr}
    \counterwithout{myfloat}{chapter}
    \counterwithout{figure}{chapter}
    \counterwithout{table}{chapter}%%--no chapter numbers in floats ("1" instead of "1.1")


    \usepackage[singlelinecheck=false, format=plain]{caption}

    \addtokomafont{caption}{\gillfont}
    \addtokomafont{captionlabel}{\gillfont}

    \usepackage{lipsum}


    \begin{document}

    \begin{textbox}{More details}\label{box1}
    \lipsum[1]
\end{textbox}

\begin{figure}[h]
    \includegraphics[width=0.4\linewidth]{example-image-a}
    \caption{\lipsum[2]}
\end{figure}

\end{document}

Answer 1

Aquí hay otra sugerencia sin paquetes newfloaty caption. Además, reemplazaría paquete mdframedpor paquete tcolorbox.

\documentclass{scrreprt}
\usepackage{lmodern}
\usepackage[T1]{fontenc}
\usepackage[english]{babel}

%%%---being able to use all installed fonts (must compile with LuaLaTeX!)
\usepackage{fontspec}
\newfontfamily\gillfont{Gill Sans MT}

\DeclareNewTOC[
  type=myfloat,
  float,% defines floating environment myfloat
  %nonfloat,% defines nonfloating environment myfloat-
  tocentryindent=1.5em,
  tocentrynumwidth=2.3em,
  name=Box,
  listname={Boxes},
  atbegin={\addtokomafont{caption}{\gillfont}\addtokomafont{captionlabel}{\gillfont}}
]{frm}

\usepackage{tcolorbox}
\newenvironment{textbox}[1]
  {\begin{myfloat}[tb]
    \begin{tcolorbox}[colback=gray!10,arc=0mm,boxrule=.4pt]
      \caption{#1}%
  }
  {\end{tcolorbox}\end{myfloat}}


%\usepackage{chngcntr}% needed for older TeX distributions
\counterwithout{figure}{chapter}
\counterwithout{table}{chapter}
\KOMAoptions{captions=nooneline}% can also be set as class option
\setcapindent{0pt}

\usepackage{lipsum}% only for dummy text
\begin{document}
\listofmyfloats
\listoffigures
\clearpage
\begin{textbox}{More details}\label{box1}
  \lipsum[1]
\end{textbox}

\begin{figure}[hb]
  \includegraphics[width=0.4\linewidth]{example-image-a}
  \caption{\lipsum[2]}
\end{figure}
\end{document}

Si desea utilizarlo \captionof{myfloat}{...}también, reemplace el \DeclareNewTOCcomando en el ejemplo anterior por

\DeclareNewTOC[
  type=myfloat,
  float,% defines floating environment myfloat
  %nonfloat,% defines nonfloating environment myfloat-
  tocentryindent=1.5em,
  tocentrynumwidth=2.3em,
  name=Box,
  listname={Boxes}
]{frm}
\makeatletter
\addtokomafont{caption}{\ifstr{\@captype}{myfloat}{\gillfont}{}}
\addtokomafont{captionlabel}{\ifstr{\@captype}{myfloat}{\gillfont}{}}
\makeatother
