How might the longtable environment have to be modified to create a longquadro environment?

Question

To give some context: I have a long list of risks I want to put in my document and managed to make it work using longtable as can be seen in pic1 (It's in portuguese because it's my masters disstertaion).

The problem I'm facing here is that longtables are always recognized as Tables and I would like to be able to use a custom float named quadro, that is created as part of the template I'm using which is defined below:

\newcommand{\listquadroname}{Lista de quadros}
\newcommand{\quadroname}{Quadro}
\newcommand{\quadrorefname}{Quadro}
\newcommand{\chartautorefname}{Quadro}
\addto\captionsenglish{% ingles
    \renewcommand{\listquadroname}{List of charts}
    \renewcommand{\quadroname}{Chart}
    \renewcommand{\quadrorefname}{Chart}
    \renewcommand{\chartautorefname}{Chart}
}
\newfloat{quadro}{htbp}{loq}[chapter]
\floatname{quadro}{\quadroname}
\floatstyle{plaintop}
\restylefloat{quadro}
\newlistof{listofquadros}{loq}{\listquadroname}
\newlistentry{quadro}{loq}{0}
\renewcommand{\thequadro}{\thechapter.@arabic\c@quadro}
\setfloatadjustment{quadro}{\centering}
\renewcommand{\cftquadroname}{\quadroname\space}
\renewcommand*{\cftquadroaftersnum}{\hfill\textendash\hfill}
\begin{quadro}[htb]
\caption{Editores de Texto Livres}
\label{quadro:editores_texto_livres}
\centering
\begin{tabular}{|l|l|r|}        \hline
Editor     & Multiplataforma & Específico para Latex \ \hline
Kwriter    & Sim             & Não                   \
Texmaker   & Sim             & Sim                   \
Kile       & Sim             & Sim                   \
Geany      & Sim             & Não                   \ \hline
\end{tabular}
\end{quadro}

That being said, how might I edit the longtable environment to create a longquadro environment that not only follows the same naming convention but also is included in the same lists (like List of Quadros).

Answer 1

This should work:

\documentclass{abntex2}
\usepackage{float}
\usepackage{longtable}
\usepackage{xpatch}
%%changed to make generic
\providecommand{\listquadroname}{}
\providecommand{\quadroname}{}
\providecommand{\quadrorefname}{}
\providecommand{\chartautorefname}{}
\addto\captionsbrazil{%
  \renewcommand{\listquadroname}{Lista de quadros}%
  \renewcommand{\quadroname}{Quadro}%
  \renewcommand{\quadrorefname}{Quadro}%
  \renewcommand{\chartautorefname}{Quadro}%
}
\addto\captionsenglish{%
  \renewcommand{\listquadroname}{List of charts}%
  \renewcommand{\quadroname}{Chart}%
  \renewcommand{\quadrorefname}{Chart}%
  \renewcommand{\chartautorefname}{Chart}%
}
%%%
\newfloat{quadro}{htbp}{loq}% <--- changed
\counterwithin{quadro}{chapter}% <--- added
\floatname{quadro}{\quadroname}
\floatstyle{plaintop}
\restylefloat{quadro}
\newlistof{listofquadros}{loq}{\listquadroname}
\newlistentry{quadro}{loq}{0}
\renewcommand{\thequadro}{\thechapter.\arabic{quadro}}% <--- changed
\setfloatadjustment{quadro}{\centering}
\renewcommand{\cftquadroname}{\quadroname\space}
\renewcommand*{\cftquadroaftersnum}{\hfill\textendash\hfill}
\makeatletter
\newenvironment{longquadro}
 {%
  \let\c@table\c@quadro\let\thetable\thequadro
  \def\fnum@table{\quadroname{ }\thequadro}%
  \xpatchcmd{\NRorg@LT@c@ption}{{lot}{table}}{{loq}{quadro}}{}{}%
  \xpatchcmd{\NRorg@LT@c@ption}{{lot}{table}}{{loq}{quadro}}{}{}%
  \renewcommand{\theHtable}{quadro\thechapter.\arabic{quadro}}%
  \longtable
 }
 {\endlongtable}
\makeatother
\begin{document}
\listofquadros
\chapter{First}
\begin{quadro}[htp]
\caption{Test}
\end{quadro}
\begin{longquadro}{|l|l|r|}
\caption{Editores de Texto Livres}

\end{longquadro}
\end{document}

Check the changes I made to your code.

Answer 2

Since this is a follow-up question of Trying to use longtable to make it span multiple pages but can't control to which list it goes to, the following example is also based on the one given in the answer (posted by myself) there.

General notes:

• The key is to do the patch locally inside environment longquadro.
• To avoid the problem of nesting \xpatchcmd\cmd{<... containing #1>}{}{<true>}{<false>} inside a macro, \LT@c@ption is directly redefined rather than patched.
