For some applications, e.g. Links in mindmap as table of contents in beamer the default beamer table of contents is not flexible enough

How to manually recreate a basic beamer toc as starting point for crazy things?

The following code produces a rudimentary toc with much less functionality than the origional beamer toc, but it really just meant as a starting point for more complicate things that would not be possible with the default toc.

documentclass{beamer}



usepackage{tikz}



setbeamercolor{subsection in toc}{fg=black}



% total number of sections %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

usepackage{totcount}

newcounter{totalsection}

regtotcounter{totalsection}

AtBeginDocument{%

  pretocmd{section}{refstepcounter{totalsection}}{}{}%

}%



% number of subsections per section %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

usepackage{xcntperchap}

            setcounter{currentsub}{ObtainTrackedValueExp[i]{section}{subsection}}%

            par%

            begingroup

                usebeamerfont{subsection in toc}%

                usebeamercolor[fg]{subsection in toc}%
