Qt 是采用商业和开放源码许可的，跨平台应用程序和 UI 框架。它由 Qt 公司和 Qt 工程社区在开源治理模型下一起开发。
使用 Qt，一旦编写 GUI 应用程序，就可以跨桌面、移动及嵌入式操作系统部署它们，无需重写源代码。
Qt is supported on a variety of 32-bit and 64-bit platforms, and can usually be built on each platform with GCC, a vendor-supplied compiler, or a third party compiler. Open GL (ES) 2.0, DirectX 9 or 11 (with ANGLE), or an 替代渲染器 是要求的对于 Qt Quick 2. 小部件 无需硬件加速即可使用。
在 Qt 5 中所有平台的创建是使用的 Qt Platform Abstraction (QPA), which makes it easier than before to port Qt into a new operating system.
The following table lists configurations supported by The Qt Company. A configuration is a combination of an operating system version, a compiler version, and a graphics system.

参考配置运行在 Qt 工程的 CI (持续集成) 系统中。此外，它们经常 (在新版本发，源代码树分支前，及在开发过程中的其它重要时间点) 受制于单元测试套件和其它内部测试工具。会优先修正在这些平台发现的错误 (或 Bug)。测试配置中发现的重大错误会影响发行日期。
Any configurations not listed above are not actively tested by the Qt Project. However, Qt may run on configurations other than those actively tested on, and additional configurations may be raised to tested state, if sufficient effort is made to bring continuous integration to an acceptable state for that particular configuration.
The following page lists the configurations supported by The Qt Company for each released Qt version:
The Qt Company, Qt partners, open source projects and community users are able to provide assistance with various different supported platforms and configurations.
