Detailed Description

The QML global Qt object provides useful enums and functions from Qt.

QmlGlobalQtObject

Note: The Qt object provides useful enums and functions from Qt, for use in all QML files.

The Qt object is a global object with utility functions, properties and enums.

It is not instantiable; to use it, call the members of the global Qt object directly. For example:

import QtQuick 1.0
Text {
    color: Qt.rgba(1, 0, 0, 1)
    text: Qt.md5("hello, world")
}

The Qt object contains the enums available in the Qt Namespace. For example, you can access the Qt::LeftButton and Qt::RightButton enum values as Qt.LeftButton and Qt.RightButton.

data types. This is primarily useful when setting the properties of an item when the property has one of the following types:

color - use QML:Qt::rgba() "Qt.rgba()", QML:Qt::hsla() "Qt.hsla()", QML:Qt::darker() "Qt.darker()", QML:Qt::lighter() "Qt.lighter()" or QML:Qt::tint() "Qt.tint()"
rect - use QML:Qt::rect() "Qt.rect()"
point - use QML:Qt::point() "Qt.point()"
size - use QML:Qt::size() "Qt.size()"
vector3d - use QML:Qt::vector3d() "Qt.vector3d()"

There are also string based constructors for these types. See QML Basic Types for more information.

/Time-Formatters

The Qt object contains several functions for formatting QDateTime, QDate and QTime values.

QML:Qt::formatDateTime "string Qt.formatDateTime(datetime date, variant format)"
QML:Qt::formatDate "string Qt.formatDate(datetime date, variant format)"
QML:Qt::formatTime "string Qt.formatTime(datetime date, variant format)"

The format specification is described at QML:Qt::formatDateTime "Qt.formatDateTime".

items from files or strings. See Dynamic Object Management in QML for an overview of their use.

QML:Qt::createComponent() "object Qt.createComponent(url)"
QML:Qt::createQmlObject() "object Qt.createQmlObject(string qml, object parent, string filepath)"
