Turbo Vision

By default, Turbo Vision applications replicate the look and feel of these IDEs, including edit controls, list boxes, check boxes, radio buttons and menus, all of which have built-in mouse support.

Later it was deprecated in favor of Object Windows Library, the Win16 API, and the GUI tools of Borland Delphi.

Around 1997, the C++ version, including source code, was released by Borland into the public domain[1][2] and is currently being ported and developed by an open-source community on SourceForge under the GPL license.

[4] Over the years this codebase has grown stable on nearly all operating systems and architectures that FPC supports.

One of the factors limiting Turbo Vision's popularity was the absence of Unicode support in the original Borland version.
