Excerpt: Qt (pronounced officially as cute , though more commonly as Q.T. ) is a cross-platform application framework that is widely used for developing application software with a graphical user interface (GUI) (in which cases Qt is referred to as a widget toolkit), and also used for developing non-GUI programs such as command-line tools and consoles for servers. Qt is most notably used in Autodesk Maya, Dassault DraftSight, Google Earth, KDE, Adobe Photoshop Album, the European Space Agency, OPIE, Siemens, Volvo, Walt Disney Animation Studios, Skype, VLC media player, Samsung, Philips, Panasonic, VirtualBox and Mathematica. It is produced by Nokia's Qt Development Frameworks division, which came into being after Nokia's acquisition of the Norwegian company Trolltech, the original producer of Qt. Nokia announced that it is going to drop Symbian technologies and base their future smartphones on Microsoft platform instead in February 2011. One month later Nokia announced the acquisition of Qt's commercial licensing and professional services by Digia PLC, although Nokia will remain the main development force behind the framework. On 9th May, it was announced on the Qt Labs website that the groundwork was being laid for the next major version of Qt, with the expectation that Qt 5 would be released in 2012. Qt uses standard C++ but makes extensive use of a special code generator (called the Meta Object Compiler, or moc) together with several macros to enrich the language. Qt can also be used in several other programming languages via language bindings. It runs on all major platforms and has extensive internationalization support. Non-GUI features include SQL database access, XML parsing, thread management, network support, and a unified cross-platform API for file handling. Distributed under t...
