It seems like "delete this" is what you want. If you just want to hide the
dialog then use hide().

Why would it be important to you to destroy the underlying C instance? We have
spent a long time ensuring that the lifetime of the C++ wrappers is tightly
bound to the lifetime of the C objects. I think it would be best to forget
about the underlying C instances whenever possible.
