JVCL Components

JVCL is a library of more than 600 Delphi visual and non-visual components (https://github.com/project-jedi/jvcl). Although heavily Windows-centered, some of them have been ported to Lazarus.

Packages

Due to the large number of components the original Delphi version is split into a variety of packages. The Lazarus port follows this convention because the user can install only the functionality needed.

For each package, a runtime and designtime version is available. Runtime packages can be identified with an appended R, designtime packages with an appended D. In the requirements for a project always use the runtime package.

JvCoreLazR and JvCoreLazD

Provides basic functionality needed by all other packages.
