Qt Quick Controls

Qt Quick Controls provides a set of controls that can be used to build complete interfaces in Qt Quick. The module was introduced in Qt 5.7.

Qt Quick Controls comes with a selection of customizable styles. See Styling Qt Quick Controls for more details.

Using the Module

QML API

The QML types of the module are available through the QtQuick.Controls import. To use the types, add the following import statement to your .qml file:

import QtQuick.Controls

C++ API

Using a Qt module's C++ API requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.

Building with CMake

Use the find_package() command to locate the needed module component in the Qt6 package:

find_package(Qt6 REQUIRED COMPONENTS QuickControls2)
target_link_libraries(mytarget PRIVATE Qt6::QuickControls2)

For more details, see the Build with CMake overview.

Building with qmake

To configure the module for building with qmake, add the module as a value of the QT variable in the project's .pro file:

QT += quickcontrols2

Building From Source

The Qt Image Formats module is recommended, but not required. It provides support for the .webp format used by the Imagine style.

Versions

Qt Quick Controls 2.0 was introduced in Qt 5.7. Subsequent minor Qt releases increment the import version of the Qt Quick Controls modules by one, until Qt 5.12, where the import versions match Qt's minor version.

In Qt 6, both the major and minor versions match, and version numbers may be omitted from imports in QML. If the version is omitted, the latest version will be used.

The experimental Qt Labs modules use import version 1.0.

Module Evolution

Qt Quick Controls was originally written with touch interfaces as the primary focus. While it is already possible to develop desktop interfaces, work is ongoing to provide a more native look and feel.

Changes to Qt Quick Controls lists important changes in the module API and functionality that were done for the Qt 6 series of Qt.
