Beamer, overview of all the subsections of my current section

Question

I would like to get for my beamer presentation, using smoothbars, the overview of all the subsections of my current section. I would like to see the subsections as how the sections look.

\usetheme{Madrid}
\useoutertheme{smoothbars}
\setbeamertemplate{mini frames}{}

I've used the following code but I don't obtain the result :

\makeatletter
\setbeamertemplate{subsection in smoothbars}
       {\vspace*{-\baselineskip}}
\makeatother

Can somebody help ?

You can redefine the headline beamer template as defined in beamerouterthemesmoothbars.sty to use \insertsubsectionnavigationhorizontal instead of the default \insertsubsectionhead; something along these lines:

\documentclass{beamer}
\usetheme{Madrid}
\useoutertheme{smoothbars}
\setbeamertemplate{mini frames}{}

\makeatletter
\setbeamertemplate{headline}
{%
  \pgfuseshading{beamer@barshade}%
  \ifbeamer@sb@subsection%
    \vskip-9.75ex%
  \else%
    \vskip-7ex%
  \fi%
  \begin{beamercolorbox}[ignorebg,ht=2.25ex,dp=3.75ex]{section in head/foot}
    \insertnavigation{\paperwidth}
  \end{beamercolorbox}%
  \ifbeamer@sb@subsection%
    \begin{beamercolorbox}[ignorebg,ht=2.125ex,dp=1.125ex,%
      leftskip=.3cm,rightskip=.3cm plus1fil]{subsection in head/foot}
      \usebeamerfont{subsection in head/foot}\insertsubsectionnavigationhorizontal{\dimexpr\paperwidth-0.6cm\relax}{}{}
    \end{beamercolorbox}%
  \fi%
}
\makeatother
