  Visual Component Library - Wikipedia, the free encyclopedia
In computing, VCL (Visual Component Library) is a visual component-based framework for developing Microsoft Windows applications, developed by Borland for use in its Delphi and C++Builder software development environment.
A cross-platform equivalent of VCL called CLX (Component Library for Cross Platform) was later developed for use in Delphi, C++Builder and Kylix.
The VCL approach is common because it was used by Smalltalk, the first true object-oriented programming language.

 Historical Document: Visual Component Library First Draft - May 24, 1993   (Site not responding. Last check: 2007-09-19)
VCL is a set of components that are used and combined to construct an application.
VCL is easy to use and does not require prior knowledge of Windows programming, the use of pointers, allocating and deallocating dynamic memory, or object-oriented programming.
All components are dynamically allocated and the reference model allows a simplified syntax for referring to dynamically allocated objects in the same way that a var parameter allows a pointer-free reference to a formal parameter.

 C++Builder, 1, Borland C++Builder White Paper: C++Builder and VCL   (Site not responding. Last check: 2007-09-19)
The Visual Component Library, introduced in Delphi 1.0, is a framework consisting of classes and components that you use to create Delphi applications.
Components are the building blocks that developers use to design the user-interface and to provide some non-visual capabilities to their applications.
The VCL wrappers simply make the control available to you in the form of a C++Builder component-it doesn't define the common control's appearance or functionality, but rather, surfaces the ability to modify a control's appearance/functionality in the form of methods and properties.

 C++Builder 5 Developer's Guide: Overview of component creation   (Site not responding. Last check: 2007-09-19)
When you create a component, you add to the VCL by deriving a new class from one of the existing class types in the hierarchy.
Each new component must have a constructor that overrides the constructor of the class from which it was derived.
When you call the component's constructor, you must pass a parameter specifying the owner of the component (the component responsible for destroying the component when the time comes).
