QObject explicit constructing and QSharedData

[kornicameister]

class QubiconModelData;
class QubiconModel : public QObject {
public:
    QubiconModel();
    QubiconModel(const QubiconModel &);
    QubiconModel &operator=(const QubiconModel &);
    ~QubiconModel();
 
private:
    QExplicitlySharedDataPointer<QubiconModelData> data;
};

class QubiconModelData;
class QubiconModel : public QObject {
public:
    QubiconModel();
    QubiconModel(const QubiconModel &);
    QubiconModel &operator=(const QubiconModel &);
    ~QubiconModel();
    
private:
    QExplicitlySharedDataPointer<QubiconModelData> data;
};

here is the header...I didn't wrote it myself, this particular part of code has been auto-generated via QtCreator new class wizard.

It won't work. QObject instances can't be copied. Why do you want to derive that class from QObject?

Wanted to have out-of-the-box support for automatic objects deallocation...however it seems that since it is not possible I will just take care of it myself

I don't see how that's related. If you have a value-based class that contains a shared data pointer then you allocate such objects on the stack and you don't need any special automatic object deallocation because deallocation is automatic by the definition. If you allocate such objects on the heap, then you usually don't need them to be based around shared data and even if you do, you can use an external smart pointer to manage such object.

That's some useful explanation...thank you
