Additional Modules | Qt 6.11 (original) (raw)

Qt Add-On modules bring additional value for specific purposes. These modules may only be available on some development platform. Many add-on modules are either feature-complete and exist for backwards compatibility, or are only applicable to certain platforms. Each add-on module specifies its compatibility promise separately.

The Qt installers include the option of downloading the add-ons. For more information, visit the Getting Started with Qt page.
