[Qt-qml] QML C++ Plugin template in Qt Creator

[Jamil Naja]

Hi

I have a question regarding generating a QML extension plugin using Qt
Creator:

Isn't there a contradiction between the disabling the copy constructor and
declaring  the class as a MetaType (done by QML_DECLARE_TYPE)  ?

The documentation
<http://doc.trolltech.com/latest/qmetatype.html#Q_DECLARE_METATYPE>says that
types that are know to QMetaType should have a public copy constructor.

class MyItem : public QDeclarativeItem

{

.....

Q_DISABLE_COPY(MyItem)
.....
};
QML_DECLARE_TYPE(MyItem)


It would be great if you explain why these two lines are added to the
generated code as well and what are the implications of not having them,
especially since the tutorial
<http://doc.qt.nokia.com/latest/declarative-tutorials-extending-chapter6-plugins.html>on
how to create an extension plugin uses neither of those macros


Thanks
Jamil
