Writing custom Qt Quick components using OpenGL - Video

Qt Quick and QML provide an easy way to rapidly develop customized, reusable components entirely within QML. As these components grow in complexity, performance and maintainability often suffer, a drawback that is especially noticeable on low-powered embedded and mobile devices. In addition, some specialized components simply cannot be implemented by combining existing Qt Quick items in QML. For these cases, Qt Quick provides access to its underlying OpenGL scene graph via a C++ API. Components created this way are more closely aligned to the underlying scene graph architecture allowing improved performance and a cleaner implementation.
