C++ API

The C++ API documentation is written for developers who develop the Qt Installer Framework. It describes the internal API, so there is no compatibility promise. Further, the documentation is a work in progress and therefore parts of it are missing while other parts might be out of date.

To create customized installers, use the Scripting API, instead. For more information, see Customizing Installers.
