QML Application Developer Resources
QML is a declarative language that allows user interfaces to be described in terms of their visual components and how they interact and relate with one another. It is a highly readable language that was designed to enable components to be interconnected in a dynamic manner, and it allows components to be easily reused and customized within a user interface. Using the QtQuick module, designers and developers can easily build fluid animated user interfaces in QML, and have the option of connecting these user interfaces to any back-end C++ libraries.
Other QML modules
Qt Quick only provides basic visual types, much of Qt's functionality is exposed to QML through other modules. If you require the functionality of those modules, you should browse their QML documentation. Qt Essentials modules exposing QML types include:
- QtMultimedia for playing and managing multimedia content and cameras.
- QtWebkit for rendering web content.
- QML Basics
- QML Essentials

What is QML?
What is Qt Quick?
Qt Quick is the standard library of types and functionality for QML. It includes visual elements, interactive elements, animations, models and views, particle effects and shader effects. A QML application developer can get access to all of that functionality with a single import statement.
The QtQuick QML library is provided by the Qt Quick module. For in-depth information about the various QML types and other functionality provided by Qt Quick, please see the Qt Quick module documentation.
