I'm playing with QtD, and I tried to override a QWidget's sizeHint() function, which is declared as const QSize sizeHint(). I tried to override it by declaring my function as override const(QSize) sizeHint () . I got a compiler error that it was "not covariant" with const QSize, and when I changed it to that it worked fine. I've skimmed through the documentation but don't understand what the difference is. Any help?
