Qt Modules

Qt Essentials

Qt Essentials define the foundation of Qt on all platforms. They are available on all supported development platforms and on the tested target platforms. Except the testing modules, which will remain source compatible, these modules will remain source and binary compatible throughout the lifetime of the major Qt version.

Qt Addons

Addon modules bring additional value for specific purposes. These modules may only be available on some of the development platforms.
