A custom class, a copy constructor and a warning

J.Hilk

Hello everyone,

I'm currently in the process of cleaning up my code and I stumbled over a particular compiler warning:

base class 'class QObject' should be explicitly initialized in the copy constructor
Datagram::Datagram(const Datagram &data)

I only have QObject as a base class, to define enums in it and to register is as a Metaobject.
I need to pass it around via Signal&Slots and a QueuedConnection.

I do not explicitly initalize QObject in the different constructors either.

The warning is only there with the mingw-compiler, msvc and clang have no problems with it.

So how would I do that?

heres my copy constructor:

Datagram::Datagram(const Datagram &data)
{
    m_data = data.m_data;
    m_Type = data.m_Type;
}

I only have QObject as a base class, to define enums in it and to register is as a Metaobject.

That's what Q_GADGET is for. Remove the base class and replace Q_OBJECT with Q_GADGET

@VRonin Well apparently it is oO.
Wasn't ware of that one, I came by it when googled the warning, but gave it not much mind.

Thank you!
