Изменение названия окна

Question

Столкнулся с проблемой, не могу найти способ изменить название окна и самой программы.

Я пробовал MainWindow.setWindowTitle('New Title") но это не помогло, не совсем понял что значит это в аргменте к функции - const QString &

НИКОГДА НЕ ИЗМЕНЯЙТЕ код, сгенерированный Qt Designer, НИКОГДА.
Создайте другой класс, который наследуется от соответствующего виджета, и используйте созданный класс для его заполнения.

windowTitle : QString

Это свойство содержит заголовок окна
