Subclass QList<T>

[ChrisW67]

I want to make a subclass of QList for any type T.

QList already is list of arbitrary type T. It already is a template class.

You are right. But I want to override some function of QList later, so I try to make a simple copy subclass first.

QList is not designed to be inherited and have its behaviours overridden: it has no virtual functions. Its destructor is not virtual so polymorphic pointers (if you were intending to use them) will also be dangerous. You could add behaviours like QStringList does.

You usually better off either using QList<T> as-is or incorporating it by composition rather than inheritance.
