Visual Component Library
VCL

    VCL A application framework library for
   Microsoft Windows and Borland Software Corp.'s Delphi
   and C++Builder rapid application development software.
   VCL was originally designed for Delphi but is now also used
   for C++Builder.  This replaces OWL Object Windows Library
   as Borland's Windows C++ framework of choice.  VCL
   encapsulates the C-based Win32 API into a much easier to
   use, object-oriented form.  Like its direct rival,
   Microsoft Foundation Class Library (MFC), VCL includes
   classes to create Windows programs.

   The VCL component class can be inherited to create new VCL
   components, which are the building blocks of Delphi and
   C++Builder applications.  VCL components are somewhat in
   competition with ActiveX controls, though a VCL wrapper can
   be created to make an ActiveX control seem like a VCL
   component.
