Component Library for Cross Platform

In computing, Component Library for Cross Platform (CLX), is a cross-platform visual component-based framework for developing Microsoft Windows and Linux applications. It is developed by Borland for use in its Kylix, Delphi, and C++Builder software development environment. There is a Microsoft Windows-only equivalent of CLX called VCL (Visual Component Library).

In terms of object-oriented approach, the CLX forms a object hierarchy where the TObject class serves as the base class. All other classes inherit or indirectly inherit the TObject class. This is a common approach because it's what Smalltalk, the first true object-oriented programming language, originally did. This approach is shared by the Java programming language, Java has a base class called Object. This is necessary as Delphi does not support multiple inheritance, unlike C++.
