'''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 programming tool|Kylix]], [[Delphi programming language|Delphi]], and [[C++ Builder]] software development environment.

In terms of [[Object-oriented programming|object-oriented]] approach, the CLX forms an object hierarchy where the TObject class serves as the ''[[Superclass (computer science)|base class]]''. All other classes inherit or indirectly inherit the TObject class. This is necessary as Delphi does not support [[multiple inheritance]], unlike C++. This is a common approach shared by the [[Java (programming language)|Java programming language]], [[Smalltalk]], and many other [[object-oriented programming language]]s.

The [[Application programming interface|API]] of CLX followed almost completely the VCL. It was envisioned that existing application using VCL will be simply recompiled with CLX.

Today, many concepts that were defined with CLX have been implemented with the [[Lazarus Component Library]] (LCL) for the [[Lazarus (IDE)|Lazarus]] IDE. By docking to different [[widgetset]]s, the LCL is able to support an even larger spectrum of platforms including [[Mac OS X]] and [[Android (operating system)|Android]].

However, due to lacklustre performance on Windows, subtle differences from VCL and bugs it didn't became the expected successor of VCL. Commercial failure of Kylix stopped further development of CLX.
