How to set a forward declaration with generic types under Delphi 2010?

Question

I run into what seems to be a very classical problem: An item and a collection class, both referencing each other, that require a forward declaration. I\'m using Delphi 2010

Answer 1

You can work around it by declaring an ancestor class:

type
  TBaseElement = class
  end;

  TMyCollection = class
  end;

  TMyElement = class(TBaseElement)
  private
    FParent: TMyCollection;
  end;
