of CLX almost completely followed VCL. It was envisioned that existing applications using VCL would be recompiled with CLX.

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

In terms of object-oriented approach, CLX forms an object hierarchy where the TObject class serves as the base class. All other classes inherit or indirectly inherit the TObject class.
