Why is it not allowed to copy QObjects?
Entry number: 582 - Why is it not allowed to copy QObjects?
Answer:
The reason it is not possible to copy QObjects is that QObject is a polymorph object, and that
polymorph objects cannot be copied.
QPushButton pushButton;
QObject object = pushButton;
Q_ASSERT(object.metaObject() == &QPushButton::staticMetaObject).
This would assert, and all calls of virtual functions would call QObject's
implementation.
