Visual Component Library




Much of popularity of VCL comes from its tight integration with visual RAD tools from Borland.

A cross-platform equivalent of VCL called CLX (Component Library for Cross Platform) was later developed for use in Delphi, C++ Builder and Kylix , it was however abandoned in favor of VCL.

As an Object-oriented approach, the VCL forms an object hierarchy where all other objects inherit or indirectly inherit the TObject class. This is necessary as Delphi does not support multiple inheritance, unlike C++ . The VCL approach is common because it was used by Smalltalk , the first true Object-oriented Programming Language . This approach is shared by the Java Programming Language , which has a base class called Object.
