To use the module, import the QtQuick module with the following statement:

 import QtQuick

Visit the Qt Quick module documentation for more information about the concepts that are central to QtQuick.

Submodules

Qt Quick includes several submodules that contain additional types:

  • Local Storage - a submodule containing a JavaScript interface for an SQLite database
  • Particles - provides a particle system for QML applications
  • Controls - provides a set of reusable UI components
  • Layouts - contains types that are used to arrange items in the user interface
  • Tests - types for testing QML applications.
  • Effects - provides types for applying one or more simple graphical effects to Qt Quick items.
