Ошибка: NameError: name 'QtGui' is not defined

Question

Хотел запустить программу с графическим интерфейсом.

if __name__ == "__main__": (и то что внутри) написал вручную, потому что после конвертации (.ui в .py) этого кода не было.

После запуска программы выходит ошибка

NameError: name 'QtGui' is not defined

Что не так?

Answer 1

я же вам написал Form = QWidget(), а не Form = QtWidgets()

В общем ваше приложение может выглядеть так, закомментируйте мои импорты и раскомментируйте свои. Я отметил строки, в которые внес изменения.

Но учитывая, что вы вероятно захотите оживить свое приложение и добавить какую-то логику, я вам предложу попробовать вариант как правильно это сделать.
