Third-Party Code Used in Qt

Qt libraries and plugins can contain code that is not intellectual property of The Qt Company, but is available under specific open-source licenses from the original authors.

The Qt Company gratefully acknowledges these and other contributions to Qt. We recommend that programs that use Qt also acknowledge these contributions and quote these license statements in an appendix to the documentation.

Note: You only need to acknowledge and comply with the licenses of the third-party components that you are actually shipping with your application. Click the name of the component to see the licensing details.
