Qt Quick is a framework that provides a declarative way of building custom, highly dynamic user interfaces with fluid transitions and effects, which are becoming more and more common especially in mobile devices.

Qt Declarative is a runtime interpreter that reads the Qt declarative user interface definition, QML data, and displays the UI that it describes. The QML syntax allows using JavaScript to provide the logic, and it is often used for this purpose. It is not the only way, however: logic can be written with native code as well.

Qt Quick and QML are officially supported in Qt 4.7 (with Qt Creator 2.1), and it is a commercial option in mobile applications when Qt 4.7 is available for deployment in Symbian and Maemo/MeeGo devices.

Qt Quick provides everything needed to create a rich application with a fluid and dynamic user interface. It enables user interfaces to be built around the behavior of user interface components and how they connect with one another, and it provides a visual canvas with its own coordinate system and rendering engine. Animation and transition effects are a first class concept in Qt Quick, and visual effects can be supplemented through specialised components for particle and shader effects.
