Qt WebEngine 授权许可

Qt WebEngine 模块使用 Chromium 提供大部分功能。在构建过程中，Chromium 成为Qt WebEngine 核心库的一部分。因此，在发布Qt WebEngine 时，用户需要同时遵守在 Qt Project 下开发的Qt WebEngine 部分的许可证以及作为 Chromium 一部分的许可证。

Qt WebEngine 模块的 Qt 特定部分可从 The Qt Company 获得商业许可。此外，它们也可在 GNU Lesser General Public License v3.0 或 GNU General Public License v3.0 或 GNU General Public License v2.0 下使用。

Chromium 部分包含各种许可证下的代码，其中限制性最强的许可证是GNU Lesser General Public License v2.1(LGPL 2.1)。如需完整列表，请参阅下面的第三方许可证。

遵守 LGPL 2.1

Qt XML Company 允许商业客户在发布Qt WebEngine 二进制文件的同时发布Qt WebEngine 模块的源代码，并允许接收者根据源代码定制和构建Qt WebEngine 。这包括在使用以其他方式获得商业许可的 Qt 的应用程序或系统中构建和使用这种修改后的Qt WebEngine 。

Qt Company 还根据 GNU Lesser General Public License v3.0、或 GNU General Public License v3.0 或 GNU General Public License v2.0 保留Qt WebEngine 模块的 Qt 特定部分，即使WebEngine 是作为纯商业长期支持版本（LTS，另请参阅长期支持版本）的一部分发布的。

第三方许可证

Chromium 源码中包含的第三方许可证如下。

注意： 以下列出的 GPL 许可证仅用于访问 Linux 系统资源。Qt WebEngine 库和插件不会链接或分发 GPL 二进制代码，也不会影响Qt WebEngine 的用户。
