How can I check if the current code is inside a tikzpicture?

Question

I read the answer for this question (inside a environment) but I would like to know if there is something more specific. LaTeX keeps the current environment in the macro \@currenvir but how do the test with the plain TEX format or the ConTEXt format.

TikZ has a command \tikzifinpicture that does the test:

\tikzifinpicture{true branch}{false branch}

However, the comments in the definition of the command (tikz.code.tex) say

% TT: This is a wrong
% test! Who uses this?...

So there may be a better way.

Thanks I imagined to test something but not \pgfutil@ifundefined{filldraw} – Alain Matthes Mar 03 '12 at 09:17

The macro works fairly well -- but not for nested pictures (i.e. it says "true" even if the current picture is temporarily interrupted). – Christian Feuersänger Mar 03 '12 at 18:17
I use it to render a PGF picture if tikzpicture environment is used to surround the picture. Then it skips the pgfpicture environment. If standalone the pgfpicture environment is used. – Jesse op den Brouw Sep 14 '21 at 16:34
