It's not. The default implementation is empty. You can check that
yourself by looking at the source file where QWidget is implemented
void QWidget::resizeEvent(QResizeEvent * /* event */)
However, I usually still call the base class implementations of
functions like that, because some of them might need to be called. For
the ones that are empty, calling them doesn't hurt.
