Qt is a cross-platform application development framework, widely used for the development of GUI programs and also used for developing non-GUI programs such as console tools and servers. Qt is most notably used in KDE, the web browser Opera, Google Earth, Skype, Qtopia and OPIE. It is produced by the Norwegian company Trolltech. Trolltech insiders pronounce Qt as "cute"^[1].

Qt uses C++ with several non-standard extensions implemented by an additional pre-processor that generates standard C++ code before compilation. Qt can also be used in several other programming languages; bindings exist for Python (PyQt), Ruby (RubyQt), PHP (PHP-Qt), Pascal, C#^[2], Perl and Java^[3]. It runs on all major platforms, and has extensive internationalization support. Non-GUI features include SQL database access, XML parsing, thread management, and a unified cross-platform API for file handling.

Since version 4, Qt has been available under a dual license, the GPL and a proprietary commercial license on all supported platforms including Windows. The commercial license allows the final application to be licensed under various free software/open source licenses such as the LGPL or the Artistic License, or a proprietary software license.

Proprietary commercial development requires the commercial license, and, unlike some open source software libraries, Qt is not licensed under the GNU Lesser General Public License and does not include a GPL linking exception.

All editions support a wide range of compilers, including the GCC C++ compiler. Official support for the Visual Studio suite [1] is, however, restricted to the proprietary Qt/Windows edition.

History

Haavard Nord and Eirik Chambe-Eng (the original developers of Qt and the CEO and President of Trolltech respectively) 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. Year 1991 (MCMXCI) was a common year starting on Tuesday (link will display the 1991 Gregorian calendar). ...

The toolkit was called Qt because the letter Q looked beautiful in Haavard's Emacs font, and "t" was inspired by Xt, the X toolkit. Look up Q, q in Wiktionary, the free dictionary. ... This article is about the text editor. ... Intrinsics (also known as Xt, for X toolkit) is a library used in the X Window System. ...

Controversy erupted around 1998 when it became clear that KDE was going to become one of the leading desktop environments for Linux. As KDE was based on Qt, many people in the free software movement worried that an essential piece of one of their major operating systems would be proprietary. Year 1998 (MCMXCVIII) was a common year starting on Thursday (link will display full 1998 Gregorian calendar). ... Information in this article or section has not been verified against sources and may not be reliable. ... This article is about operating systems that use the Linux kernel. ... The free software movement, also known as the free software philosophy, began in 1983 when Richard Stallman announced the GNU Project. ...

This gave rise to two efforts: the Harmony toolkit, which sought to duplicate the Qt Toolkit under a free software license, and the GNOME desktop, which intended to supplant KDE entirely. The GNOME Desktop uses the GTK+ toolkit, which was originally written for the GIMP, and primarily uses the C programming language. The Harmony toolkit is a never completed, free software toolkit that aimed to be API compatible with the (at the time, proprietary) Qt toolkit, but wanted to add functionality such as multi-threaded applications and pluggable themes. ... Free software is software which grants recipients the freedom to modify and redistribute the software. ... This article is about the mythical creature. ... GTK+, or the GIMP Toolkit, is one of the two most popular widget toolkits for the X Window System for creating graphical user interfaces. ...

Wikibooks has a book on the topic of C Programming The C programming language (often, just C) is a general-purpose, procedural, imperative computer programming language developed in the early 1970s by Dennis Ritchie for use on the Unix operating system. ...

Until version 1.45, source code for Qt was released under the FreeQt license — which was viewed as not compliant to the open source principle by the Open Source Initiative and the free software definition by Free Software Foundation, because while the source was available it did not allow the redistribution of modified versions. With the release of version 2.0 of the toolkit, the license was changed to the Q Public License (QPL), a free software license but one regarded by the Free Software Foundation as incompatible with the GPL. Compromises were sought between KDE and Trolltech wherein 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 BSD-style license should no free software/open source version of Qt be released during 12 months. The Open Source Initiative is an organization dedicated to promoting open source software. ... The Free Software Foundation (FSF) is a non-profit corporation founded in October 1985 by Richard Stallman to support the free software movement (free as in freedom), and in particular the GNU project. ...

The BSD daemon BSD licenses represent a family of permissive free software licenses. ...

The first two versions of Qt had only two flavours: Qt/X11 for Unix and Qt/Windows for the Windows platform. The Windows platform was only available under the proprietary license which meant free/open source applications written in Qt for X11 could not be ported to Windows without purchasing the QPL edition. In the end of 2001, Trolltech released Qt 3.0 which added support for the Mac OS X platform. The Mac OS X support was available only in the proprietary license, until June 2003, where Trolltech released Qt 3.2 with Mac OS X support available under the GPL.

In 2002 members of the KDE on Cygwin project began porting the GPL licensed Qt/X11 code base to Windows^[6]. This was in response to Trolltech's refusal to license Qt/Windows under the GPL on the grounds that Windows was not a free software/open source platform^[7]^[8]. The project achieved reasonable success although it never reached production quality. KDE on Cygwin is the port of Qt and KDE to Windows using Cygwin, the POSIX emulation layer for Windows, and the Cygwin XFree86 server. ...

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

Design

Complete abstraction of the GUI

Qt used to emulate the native look of its intended platforms, which occasionally led to slight discrepancies where that emulation wasn't perfect. Recent versions of Qt use the native APIs of the different platforms to draw the Qt controls, and so do not suffer from such issues.

Qt script for applications (QSA)

Qt Script for Applications is a cross-platform toolkit that allows developers to make their Qt/C++ applications scriptable using an interpreted scripting language: Qt Script (based on ECMAScript/JavaScript). Qt Script for Applications (QSA) is scripting engine, addon to Qt toolkit. ...

From Qt 4.3.0 onward, the scripting API ^[9], which is based on QSA ^[10] is integrated as core part of Qt and is no longer a separate library.

Meta object compiler

Known as the moc, this is a tool that is run on the sources of a Qt program prior to compiling it. The tool will generate "Meta Information" about the classes used in the program. This meta information is used by Qt to provide programming features not available in C++: The signal/slot system, introspection and asynchrone function calls. Signals and slots is a concept introduced in Qt by the moc. ... In computing, type introspection is a capability of some object-oriented programming languages to determine the type of an object at runtime. ...

The use of an additional tool has been criticized for making Qt programming different from pure C++ programming. In particular, the choice of an implementation based on macros has been criticized for its absence of type safety and pollution of the namespace. This is viewed by Trolltech as a necessary trade-off to provide introspection and the dynamically generated slot and signal mechanism.
