Differences between Qt Quick Ultralite and Qt Quick
Qt Quick Ultralite is designed to serve as application front-end rendering engine. It is different from the classical Qt in a sense that its implementation does not use typical Qt libraries, such as Qt Core or Qt Gui. Hence Qt Quick Ultralite applications need to use standard C++ containers and classes instead of those from Qt. For example, instead of using QObject or QAbstractItemModel, Qt Quick Ultralite provides a simple C++ API to expose objects and models.
Applications that require non-graphical functionalities such as networking, filesystem access, locations, and multimedia need to either have their own implementation or leverage existing 3rd party libraries for respective platforms.
