| 1 | 1 | ## About | |
| 2 | 2 | ||
| 3 | - | ||
| 3 | + | 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. This page intends to give a summary of the JVCL components available for Lazarus. Some of the info snippets were taken from <http://wiki.delphi-jedi.org/wiki/JVCL_Component_Overview>. | |

| 5 | 5 | ## Packages | |
| 6 | 6 | ||
| 7 | - | ||
| 7 | + | 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. | |
| 8 | 8 | ||
| 9 | - | ||
| 9 | + | 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. | |
| 10 | 10 | ||
| 11 | 11 | ### JvCore | |
| 12 | 12 | ||
| 13 | - | ||
| 13 | + | Provides basic functionality needed by all other packages. | |

In older Lazarus versions, there will be a warning _"The package jvcl_all does not have any "Register" procedure which typically means it does not provide any IDE addon. Installing it will probably only increase the size of the IDE and may even make it unstable."_. You can ignore this and click on _"Install it, I like the fat"_. | |

Compile the needed runtime packages (having an appended "R" at the package name). Then "Use" > "Install" the required designtime packages (having an appended "D" as the package name). It is required to rebuild the IDE only after the last package. | |
