I did not notice. Great feature.

Indeed here is a compilable latex file:
\documentclass{article}

\usepackage[english]{babel}
\usepackage{tikz}
\usetikzlibrary{fit}
\usetikzlibrary{shapes}

\begin{document}

\begin{tikzpicture}
\node[ellipse, draw] at (0,0) {
\begin{tikzpicture}
\node at (0,0.2){$blablabla$};
\node at (0,-0.2 ...

Again I found the solution (sorry for posting). I give the answer it may help someone:

Thanks for the link. It seems great !

Hello,

It seems that I have a lot of questions these days.

I am drawing two ellipses and two circles with tikZ:
\begin{tikzpicture}
\node[ellipse, draw] at (0,0) {
\begin{tikzpicture}
\node at (0,0.2){$blablabla$};
\node at (0,-0.2){$b$};
\end{tikzpicture}
};

\node[ellipse, draw] at (3.5 ...

I found a workaround:
\newcounter{result}

\newcommand{\myFunction}[4]{

\setcounter{result}{0}
\StrLen{#1}[\sOne]
\StrLen{#2}[\sTwo]
\ifthenelse{\sOne>\sTwo}{\addtocounter{result}{\sOne}}{\addtocounter{result}{\sTwo}}

\StrLen{#3}[\sThree]
\StrLen{#4}[\sFour]
\ifthenelse{\sThree>\sFour ...

Works fine, thanks !

Hello,

I want to make a function which take 4 arguments (#1 to #4) and return the size of :
- the size of the longest string between #1 and #2
plus
- the size of the longest string between #3 and #4

For example if I do:
\myFunction{a}{bc}{def}{g}
it should return 5 (because max(length(a, bc ...

Excellent thank you !

Hello,

I have a reference to a nested node which is not working as well as expected. Here is an example:
\begin{tikzpicture}
\node[draw, ellipse] (e1){
\begin{tikzpicture}
\node (n1) {$a$};
\end{tikzpicture}
};

\node[draw, ellipse] (e2) at (2,0){
\begin{tikzpicture}
\node (n2) {$b ...
