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.
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 which are central to QtQuick
.
Submodules
Qt Quick includes several submodules which 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.
Value Types
There are a number of value types that are supported by default in the QML language.
In addition, the QtQuick
import provides the following value types:
ARGB color value. The color type refers to an ARGB color value. It can be specified in a number of ways: | |
Font value with the properties of QFont. The font type refers to a font value with the properties of QFont | |
A matrix4x4 type is a 4-row and 4-column matrix | |
A quaternion type has scalar, x, y, and z attributes | |
A vector2d type has x and y attributes | |
Value with x, y, and z attributes | |
A vector4d type has x, y, z and w attributes |
Object Types
Most 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
.
