hi :slight_smile:
i want know Which functions / classes / namespaces of OPENCV need a qt library?
for example i test this function cv::createButton and i see i must install qt, i don’t want test all functions/classes/namespaces :grimacing: to understand which ones need qt and which ones do not.

the cvv module (from contrib) would also use qt
