I want a hierarchy of objects to be created with constructors that accept specific parameters. I matched the base class constructor overrides to the derived types, hoping they would get automatically called before the derived versions, but my ill-advised plans were smoked by reality. Only the base class default constructor was called. And when I tried removing the default (so that only the matching overrides remain), I can't compile it. Hopefully this will make it clear..
Car::Car(const MyData &data)
   .. I want Base::Base( data ) to be auto-called right here ..

   // otherwise, I have to do something like this..?
   Base::OnConstruct( data );

   ... init other data ...
Is there some trick to getting this to work? Thanks for any information
