The QML Reference
QML is a declarative language for creating highly dynamic applications. With QML, application building blocks such as UI components are declared and various properties set to define the application behavior. When coupled with JavaScript, application behavior becomes scriptable. In addition, QML heavily uses Qt, which allows types and other Qt features to be accessible directly from QML applications.
This reference guide describes the features of the QML language. Many of the QML types in the guide originate from the Qt QML or Qt Quick modules.
