Qt Quick QML Types

The Qt Quick module provides graphical primitive types. These types are only available in a QML document if that document imports the QtQuick namespace.

The current version of the QtQuick module is version 2.7, and thus it may be imported via the following statement:


  import QtQuick 2.7

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

Submodules

Qt Quick includes several submodules which contain additional types.

XML List Model - contains types for creating models from XML data
Local Storage - a submodule containing a JavaScript interface for an SQLite database
Particles - provides a particle system for QML applications
Window - contains types for creating top-level windows and accessing screen information
Dialogs - contains types for creating and interacting with system dialogs
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.

Basic Types

There are a number of basic types that are supported by default in the QML language.

In addition, the QtQuick import provides the following basic types:

color	ARGB color value. The type refers to an ARGB color value. It can be specified in a number of ways:
font	Font value with the properties of QFont. The type refers to a font value with the properties of QFont
matrix4x4	A matrix4x4 type is a 4-row and 4-column matrix
quaternion	A quaternion type has scalar, x, y, and z attributes
vector2d	A vector2d type has x and y attributes
vector3d	Value with x, y, and z attributes
vector4d	A vector4d type has x, y, z and w attributes

Object Types

All object types provided by the QtQuick import are based on the Item type, which itself derives from QtObject. QML object types provided by the Qt QML module (such as QtObject and Component) are also available when you import QtQuick.
