Delete object: use parent or not.

Question

Which one do you prefer to delete objects? Especially in QT, but other methods are also welcome. These two alternatives seem the same to me, right?

• Associated with another class and destroys when it is destroyed.

  SomeClass::SomeClass{
   socket_ = new QTcpSocket(this);
  }
  

or

2. Destroy in class destructor

   SomeClass::SomeClass{
    socket_ = new QTcpSocket();
   }
   
   SomeClass::~SomeClass{
    delete socket_;
   }
