How to wrap `floats` in `tcolorbox` ?

add tag

JeT

Question following this one https://topanswers.xyz/tex?q=1410 that works perfectly to display in `tcolorbox`,  `example`, `definition` environments, but not floating ones like `figure` or `table`.

How can we include the `\caption` of the `float` in title of the tcolorbox.
Can it float as the float does ? 

```
\documentclass[11pt]{article}
\usepackage{xcolor}
\usepackage{float}
\usepackage{graphics}

\usepackage[envcountsect]{beamerarticle}
\usepackage{tcolorbox}

\usepackage{xparse}

\mode<article>{
\renewtcolorbox{figure}[1][]
{colback=green!5!white, colframe=green!75!black,fonttitle=\bfseries, colbacktitle=green!85!black,
  title=#1}
}

\begin{document}
\begin{figure}[htp]
 \centering
 \includegraphics[width=0.50\textwidth]{example-image}
 \caption{My caption}
\end{figure}

\begin{frame}
 {Title of the frame}
 {Subtitle of the frame}
 \begin{block}{My block}
  My long definition that can take multiple lines, 
 \end{block}
  
 \begin{itemize}
  \item first
  \item Second
  \item third
 \end{itemize}
  
 \begin{example}[My example]
  My long example that can take multiple lines, 
 \end{example}
  
\end{frame}

\end{document}  
```

You could define a new environment `myfigure` that becomes either a floating tcolorbox in article mode or a normal figure in beamer mode:

```
\documentclass[11pt]{article}
%\documentclass{beamer}


\usepackage[envcountsect]{beamerarticle}
\usepackage{tcolorbox}

\usepackage{xparse}

\mode<article>{
\newtcolorbox[blend into=figures]{myfigure}[2][]{float=htbp,capture=hbox,
     title={#2},every float=\centering,#1}
}

\usepackage{environ}

\mode<beamer>{%
\NewEnviron{myfigure}[1]{%
    \begin{figure}%
    \BODY
    \caption{#1}%
    \end{figure}%
  }
}


\begin{document}
\begin{frame}{Title of the frame}
 {Subtitle of the frame}


\begin{myfigure}{My caption}
 \includegraphics[width=0.50\textwidth]{example-image}
\end{myfigure}



 \begin{block}{My block}
  My long definition that can take multiple lines, 
 \end{block}
  
 \begin{itemize}
  \item first
  \item Second
  \item third
 \end{itemize}
  
 \begin{example}[My example]
  My long example that can take multiple lines, 
 \end{example}
  
\end{frame}

\end{document}  
```
