Qt5.4 All Modules

Qt Essentials

Qt essentials define the foundation of Qt on all platforms. They are available on all supported development platforms and on the tested target platforms. They will remain source and binary compatible during Qt 5.

Essential modules are general and useful for a majority of Qt applications. A module that is used for a special purpose is considered an add-on module even if it is available on all supported platforms.

The following table lists the Qt essentials:

ModuleDescription
Qt CoreCore non-graphical classes used by other modules.
Qt GUIBase classes for graphical user interface (GUI) components. Includes OpenGL.
Qt MultimediaClasses for audio, video, radio and camera functionality.
Qt Multimedia WidgetsWidget-based classes for implementing multimedia functionality.
Qt NetworkClasses to make network programming easier and more portable.
Qt QMLClasses for QML and JavaScript languages.
Qt QuickA declarative framework for building highly dynamic applications with custom user interfaces.
Qt Quick ControlsReusable Qt Quick based UI controls to create classic desktop-style user interfaces.
Qt Quick DialogsTypes for creating and interacting with system dialogs from a Qt Quick application.
Qt Quick LayoutsLayouts are items that are used to arrange Qt Quick 2 based items in the user interface.
Qt SQLClasses for database integration using SQL.
Qt TestClasses for unit testing Qt applications and libraries.
Qt WebKitClasses for a WebKit2 based implementation and a new QML API. See also Qt WebKit Widgets in the add-on modules.
Qt WebKit WidgetsWebKit1 and QWidget-based classes from Qt 4.
Qt WidgetsClasses to extend Qt GUI with C++ widgets.

If you use qmake to build your projects, the Qt Core and Qt GUI modules are included by default. To link only against Qt Core, add the following line to your .pro file:

QT -= gui

On Windows, if you do not use qmake or other build tools such as CMake, you also need to link against the qtmain library.

Qt Add-Ons

Qt Add-On modules bring additional value for specific purposes. These modules may only be available on some development platform. Many add-on modules are either feature-complete and exist for backwards compatibility, or are only applicable to certain platforms. Each add-on module specifies its compatibility promise separately.

The Qt installers include the option of downloading the add-ons. For more information, visit the Getting Started with Qt page.

The following table lists the Qt add-ons:
