Questions tagged [qtquick2]

Qt Quick is a modern user interface technology that separates the declarative UI design and the imperative programming logic. Instead of the traditional C++ APIs of Qt, the presentation layer of the application is written with a Qt-specific declarative language called QML.

The Qt Quick module is the standard library for writing QML applications. While the Qt QML module provides the QML engine and language infrastructure, the Qt Quick module provides all the basic types necessary for creating user interfaces with QML. It provides a visual canvas and includes types for creating and animating visual components, receiving user input, creating data models and views and delayed object instantiation.

The Qt Quick module provides both a QML API which supplies QML types for creating user interfaces with the QML language, and a C++ API for extending QML applications with C++ code.

For more details, see the introduction to Qt Quick page in the Qt reference documentation.
