function ObjQueryInterface(const IID: TGUID; out Obj): HResult; override;
C++
virtual __fastcall HRESULT ObjQueryInterface(const TGUID IID,  Obj);
Description

The ObjQueryInterface method forwards the call first to the associated TActiveForm object if it supports the requested interface, otherwise it queries its own interface.
