In principle, I don’t see a reason why this would not be acceptable.
The devil is in the details; note that the following does not compile:
QObject parent;
QWidget widget;
widget.setParent(&parent);
as QWidget::setParent(QWidget *) shadows QObject::setParent(QObject *). The
equivalent code using addChild
QObject object;
auto child = std::make_unique<QWidget>();
object.addChild(std::move(child));
should also not compile, as a QWidget must only have another widget as the
parent.
(and thinking about it, that’s also something to keep in mind for
QObject::makeChildObject).
And all of that without qobject.h being able to include qwidget.h… which might
make this challenging.
