Я заново реализовал пример кода Qt3D в PyQt5 / Python3 с этого сайта: https://doc.qt.io/qt-5/qt3d-basicshapes-cpp-main-cpp.html
Хотя объекты отображаются правильно, обратные вызовы не работают.
Когда я нажимаю на флажки, обратные вызовы не активируются. Я пробовал разные вещи (pyqtSlots, pyqtSignal decoratos и т. Д., Но не могу понять.
Что я делаю не так? Любые предложения будут с благодарностью.
