Answer 1

I'm not sure that you are implementing your copy semantics correctly, and the use of std::auto_ptr as a data member is kind of an "alert sign".

Are your Controls really deep-copyable?

Maybe you should just use scoped_ptr instead of auto_ptr data members, ban copy declaring private copy constructor and private operator=, and use vector> ?

(Or use C++11 and move semantics, and so use unique_ptr instead of auto_ptr, and just use compiler automatically generated move operations?)
