Qt is currently being developed both by, a publicly listed company, and the under, involving individual developers and firms working to advance Qt. Qt is available with both proprietary and open source 2.0, GPL 3.0, and 3.0 licenses.

An example of a non-GUI program using Qt is the Cutelyst. GUI programs created with Qt can have a native-looking interface, in which case Qt is classified as a. It has extensive support. Non-GUI features include database access, parsing, parsing, management and network support. Programming language bindings [ ]. Main articles: and Qt uses standard with extensions including that simplify handling of events, and this helps in development of both GUI and server applications which receive their own set of event information and should process them accordingly.

Qt supports many compilers, including the C++ compiler and the suite. Qt also provides, that includes a called that allows using to provide the logic. With Qt Quick, rapid application development for mobile devices became possible, although logic can be written with native code as well to achieve the best possible performance. Qt can be used in several other via. It runs on the major desktop platforms and some of the mobile platforms. Qt market [ ]. See also: and Notable applications using Qt or are: • • • AMD's Crimson Edition driver tool application.

• • • editor • stop motion animation software • free open source numerical computing environment • • graphics editing and digital painting software •, a mathematical symbolic computation program, sometimes termed a computer algebra system or program, used in many scientific, engineering, mathematical, and computing fields. See also: Editions [ ] There are four editions of Qt available: Community, Indie Mobile, Professional and Enterprise. The Community version is under the open source licenses, while the Indie Mobile, Professional and Enterprise versions, which contain additional functionality and libraries, e.g. Enterprise Controls are commercially sold by The Qt Company. Licensing [ ] Qt is available under the following free software licenses:, and (with Qt special exception). Note that some modules are only available under a GPL license, which means that applications which statically link to these modules need to comply with that license.

In addition, Qt has always been available under a commercial license, like the, that allows developing proprietary applications with no restrictions on licensing. Software architecture [ ]. Example of Qt usage in Linux-based systems Qt, when it was first released, relied on a few key concepts: Complete abstraction of the GUI When first released, Qt used its own paint engine and controls, emulating the look of the different platforms it runs on when it drew its widgets. This made the porting work easier because very few classes in Qt depended really on the target platform; however, this occasionally led to slight discrepancies where that emulation was imperfect. Recent versions of Qt use the native style APIs of the different platforms, on platforms that have a native widget set, to query metrics and draw most controls, and do not suffer from such issues as much.

On some platforms (such as MeeGo and KDE) Qt is the native API. Some other portable graphical toolkits have made different design decisions; for example, uses the toolkits of the target platform for its implementations. Signals and slots A language construct introduced in for communication between objects which makes it easy to implement the while avoiding. The concept is that GUI can send signals containing event information which can be received by other controls using special functions known as slots. Compiler The compiler, termed moc, is a tool that is run on the sources of a Qt program. It interprets certain macros from the C++ code as annotations, and uses them to with meta information about the classes used in the program. This meta information is used by Qt to: signals and slots, and asynchronous function calls.

Qt tools [ ]. See also: Qt comes with its own set of tools to ease cross-platform development, which can otherwise be cumbersome due to different set of development tools.

Is a cross-platform for C++ and QML. 's layout/design functionality is integrated into the IDE, although Qt Designer can still be started as a standalone tool.

In addition to Qt Creator, Qt provides, a cross-platform that automates the generation of Makefiles for development projects across different platforms. There are other tools available in Qt, including the Qt Designer interface builder and the Qt Assistant help browser (which are both embedded in Qt Creator), the Qt Linguist translation tool, uic (user interface compiler), and moc (Meta-Object Compiler). Supported platforms [ ]. Main article: Qt works on many different platforms; the following are officially supported: Platform Description Linux/Unix X11 Qt for (,,,,, etc.) Wayland Qt for. Qt applications can switch between graphical backends like X and Wayland at with the -platform command line option. This allows a seamless transition of Qt applications from X11 to Wayland.

Windows RT Support for -based apps and With 5.4 minimum supported version: Other Embedded Platforms Integrity Qt for QNX Qt for VxWorks Qt for. After Nokia opened the Qt source code to the community on various ports appeared. There are also some ports of Qt that may be available, but are not supported anymore. These platforms are listed in. Software modules [ ] Starting with Qt 4.0 the framework was split into individual modules.

With Qt 5.0 the architecture was modularized even further. Qt is now split into essential and add-on modules. Qt essentials [ ] Module Description Qt Core The only required Qt module, containing classes used by other modules, including the meta-object system, concurrency and threading, containers, event system, plugins and I/O facilities. Qt GUI The central GUI module.

In Qt 5 this module now depends on, but no longer contains any widget classes. Qt Widgets Contains classes for classic widget based GUI applications and the QSceneGraph classes. Was split off from QtGui in Qt 5. Qt QML Module for and languages. Qt Quick The module for GUI application written using QML2.

History of Qt [ ]. See also: The upcoming version of Qt is Qt 5.10, which will be released on 30 November 2017 with several new features including initial support for Windows, Linux and Android. The current LTS version of Qt is 5.9 LTS which was released on 31 May 2017 and will be supported for 3 years until 31 May 2020. Early developments [ ] In the summer of 1990, Haavard Nord and Eirik Chambe-Eng (the original developers of Qt and the CEO and President, respectively, of ) were working together on a database application for ultrasound images written in C++ and running on,, and.

They began development of 'Qt' in 1991, three years before the company was incorporated as Quasar Technologies, then changed the name to Troll Tech and then to Trolltech. The toolkit was called Qt because the letter looked appealing in Haavard's typeface, and 't' was inspired by, the X toolkit. The first two versions of Qt had only two flavors: Qt/X11 for Unix and Qt/Windows for Windows.

On 20 May 1995 Troll Tech publicly released Qt 0.90 for X11/Linux with the under the Qt Free Edition License. This license was viewed as not compliant with the open source principle by the and the free software definition by because, while the source was available, it did not allow the redistribution of modified versions. Trolltech used this license until version 1.45. Controversy erupted around 1998 when it became clear that the was going to become one of the leading desktop environments for Linux. As it was based on Qt, many people in the worried that an essential piece of one of their major operating systems would be proprietary. The Windows platform was only available under a proprietary license, which meant free/open source applications written in Qt for X11 could not be ported to Windows without purchasing the proprietary edition. Becoming Free Software-friendly [ ] With the release of version 2.0 of the toolkit, the license was changed to the (QPL), a license, but one regarded by the as incompatible with the GPL.

Compromises were sought between KDE and Trolltech whereby Qt would not be able to fall under a more restrictive license than the QPL, even if Trolltech was bought out or went bankrupt. This led to the creation of the KDE Free Qt foundation, which guarantees that Qt would fall under a should no free/open source version of Qt be released during 12 months. In 2000, Qt/X11 2.2 was released under the GPL v2, ending all controversy regarding. At the end of 2001, Trolltech released Qt 3.0, which added support for Mac OS X. The Mac OS X support was available only in the proprietary license until June 2003, when Trolltech released Qt 3.2 with Mac OS X support available under the GPL.

In 2002, members of the project began porting the GPL licensed Qt/X11 code base to Windows. This was in response to Trolltech's refusal to license Qt/Windows under the GPL on the grounds that Windows was not a free/open source software platform. The project achieved reasonable success although it never reached production quality.

This was resolved when Trolltech released Qt 4.0 also for Windows under the GPL in June 2005. Qt 4 supported the same set of platforms in the free software/open source editions as in the proprietary edition, so it is possible, with Qt 4.0 and later releases, to create GPL-licensed free/open source applications using Qt on all supported platforms.

The GPL v3 with special exception was later added as an added licensing option. The GPL exception allows the final application to be licensed under various GPL-incompatible / licenses such as the 1.1. Acquisition by Nokia [ ] Nokia acquired Trolltech ASA on 17 June 2008 and changed the name first to Qt Software, then to Qt Development Frameworks. Since then it focused on Qt development to turn it into the main development platform for its devices, including a port to the. Version 1.0 of the Nokia Qt SDK was released on 23 June 2010. The source code was made available over Gitorious, a community oriented source code repository, to gather an even broader community that is not only using Qt but also helping to improve it.

On 14 January 2009, Qt version 4.5 added another option, the, which should make Qt even more attractive for non-GPL open source projects and for closed applications. In February 2011, Nokia announced its decision to drop Symbian technologies and base their future smartphones on the platform instead. One month later, Nokia announced the sale of Qt's commercial licensing and professional services to Digia, with the immediate goal of taking Qt support to, and platforms, and to continue focusing on desktop and embedded development, although Nokia was to remain the main development force behind the framework at that time. Merging and demerging with Digia [ ] In March 2011, Nokia sold the commercial licensing part of Qt to creating Qt Commercial. In August 2012, Digia announced that it would acquire Qt from Nokia. The Qt team at Digia started their work in September 2012.

They released Qt 5.0 within a month and newer versions every 6 months with new features and additional supported platforms. In September 2014, Digia transferred the Qt business and copyrights to their wholly owned subsidiary, The Qt Company, which owns 25 brands related to Qt. In May 2016, Digia and Qt demerged completely into two independent companies. The Qt Project and open governance [ ] Qt 5 was officially released on 19 December 2012. This new version marked a major change in the platform, with hardware-accelerated graphics, and playing a major role. The traditional C++-only QWidgets continued to be supported, but did not benefit from the performance improvements available through the new architecture. Qt 5 brings significant improvements to the speed and ease of developing user interfaces.

Framework development of Qt 5 moved to open governance, taking place at qt-project.org. There it is now possible for developers outside Digia to submit patches and have them reviewed. See also [ ] • • • References [ ]. • Bocklage-Ryannel, Juergen; Thelin, Johan (12 May 2015).
