Qt QML QML Types
The Qt QML module provides the definition and implementation of various convenience types which can be used with the QML language, including some elementary QML types which can provide the basis for further extensions to the QML language. The QtObject and Component object types are non-visual and provide building-blocks for extensions to QML.
The types provided by the
QtQml module are only available in a QML document if that document imports the
QtQml namespace (or if the document imports the
QtQuick namespace, as noted below).
The current version of the
QtQml module is version 2.11, and thus it may be imported via the following statement:
import QtQml 2.11
Most clients will never need to use the
QtQml import, as all of the types are also provided by the
QtQuick namespace which may be imported as follows:
import QtQuick 2.11
See the Qt Quick module documentation for more information about the
QtQuick namespace and what it provides to QML application developers.
The documentation for the types below applies equally to the types of the same name provided by the Qt Quick module, as they are in fact identical.
The following QML basic types are provided:
Value with x and y attributes
Value with x, y, width and height attributes
Value with width and height attributes
The following QML object types are provided:
Enables the arbitrary creation of property bindings
Encapsulates a QML component definition
Describes generalized connections to signals
Provides date functions
Dynamically creates objects
Provides locale specific properties and formatted data
Defines a logging category in QML
Object provides represents a number value
Provides a global object with useful enums and functions from Qt
A basic QML type
