Do not want to copy on write

I've got class member: 

QStringList list;

How to avoid copying-on-write when returning this member and updating it?

You could return a reference or a pointer to it:

QStringList& getList() {
    return list;
}

This would return just a reference to your list. But essentially this would be the same as declaring list public.

EDIT

This should work:

MyClass obj;

obj.getList().push_back("someStr");

or you could get it by reference:

QStringList& LIST = myClass.list;
