Qt cute789 is a cross platformapplication framework that is used for developing application software that can be run on various software and hardware platforms with little or no change in the underlying codebase, while still being a native application with native capabilities and speed. Qt is currently being developed both by The Qt Company, a publicly listed company, and the Qt Project under open source governance, involving individual developers and firms working to advance Qt. Qt is available with both proprietary4 and open source1. GPL 2. 0, GPL 3. 0, and LGPL 3. Purposes and abilitieseditQt is used for developing multi platform applications and graphical user interfaces GUIs however, programs without a GUI can be developed, such as command line tools and consoles for servers. An example of a non GUI program using Qt is the Cutelyst web framework. GUI programs created with Qt can have a native looking interface, in which case Qt is classified as a widget toolkit. It has extensive internationalization support. Non GUI features include SQL database access, XML parsing, JSON parsing, thread management and network support. Wxwidgets Serial Port Programming Linux In CProgramming language bindingseditQt uses standard C with extensions including signals and slots 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 GCC C compiler and the Visual Studio suite. Qt also provides Qt Quick, that includes a declarativescripting language called QML that allows using Java. Script 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 programming languages via language bindings. It runs on the major desktop platforms and some of the mobile platforms. Qt marketeditIn 2.

Applications using QteditNotable applications using Qt or QML are There are cases where applications have ported their entire code base from another toolkit to Qt to make use of a cross platform native GUI, such as the Wireshark network packet analyzer, LXQt desktop, VLC media player and the Rosegarden audio editor. EditionseditThere 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. Enterprise Controls6. The Qt Company. LicensingeditQt is available under the following free software licenses 1. GPL 3. 0, LGPL 3. LGPL 2. 1 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 Qt Commercial License,4 that allows developing proprietary applications with no restrictions on licensing. Software architectureedit. Example of Qt usage in Linux based systems. Qt, when it was first released, relied on a few key concepts Complete abstraction of the GUIWhen 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 Mee. Go and KDE Qt is the native API. Some other portable graphical toolkits have made different design decisions for example, wx. Widgets uses the toolkits of the target platform for its implementations. Signals and slots. A language construct introduced in Qt for communication between objects6. The concept is that GUI widgets can send signals containing event information which can be received by other controls using special functions known as slots. Metaobject compiler. The metaobject 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 generate added C code with meta information about the classes used in the program. This meta information is used by Qt to provide programming features not available natively in C signals and slots, introspection and asynchronous function calls. Qt toolseditQt comes with its own set of tools to ease cross platform development, which can otherwise be cumbersome due to different set of development tools. Qt Creator is a cross platform IDE for C and QML. Qt Designers GUI layoutdesign functionality is integrated into the IDE, although Qt Designer can still be started as a standalone tool.
