Architecture to eliminate "children and parent that is in a different thread"

[d_stranz]

Can this problem be resolved?

Instead of creating your QSslSocket instance in the MySslClient constructor, create it in the same thread where you create the MySslClient instance and pass the pointer in as an additional argument to the MySslClient constructor. Basically, any QObjects that have a parent-child relationship all must be created in the same thread. So any children of MySslClient have to be created in the same thread where the MySslClient instance (and its parent QObject) are created.
