![]() In addition, a framework for concurrent programming using Qt paradigms makes common threading tasks easier. Enhanced thread support allows signal-slot connections across threats and per-threat event loops.QtNetwork Module: This provides support for TCP, UDP and local sockets that are integrated with Qt’s event model, including support for Secure Socket Layer (SSL) communications, network proxy servers and network bearer management.Graphics View: This framework provides a canvas for producing interactive graphics.Qt4 Main Window Classes: These include Main Window, Toolbar, Menu and the docking architecture.Common Desktop Widgets: These are optimised to fit to support every platform.The Scribe Classes: This is a framework for creating text documents, performing low-level text layout and writing OpenDocument files.The Interview Framework: This is a model/view architecture for item views and the QtSQL module, which also uses this architecture.The Arthur Paint System: This is the Qt4 painting framework.The Tulip Container Classes: These are a set of template container classes.Qt is built on a set of core technologies provided by the QtCore and QtGui modules, and includes the following. But it doesn’t contain certain advanced features such as the table module, the XML module and the networking module. Qt professional edition: This is available for all supported platforms like UNIX/X11, embedded systems, MacOS and Windows.It can only be used to develop non-commercial software. Qt non-commercial edition: This is only available for MS Windows and contains all features of the Qt enterprise edition.It contains all features of the Qt enterprise edition and can be only used to develop software that is licensed under GPL. Qt free edition: This is only available for UNIX/X11 and embedded systems.Qt comes in several different editions, as mentioned below. Other features include SQL database access, XML parsing, JSON parsing, thread management and network support. Rapid application development for mobile devices has become possible with Qt Quick, while logic can still be written with native code as well, in order to achieve the best possible performance. Qt also provides Qt Quick, which includes a declarative scripting language called QML that allows the use of JavaScript to provide the logic. Qt supports various compilers, including the GCC C++ compiler and the Visual Studio suite, apart from having extensive international support. ![]() Non-GUI programs such as command line tools and consoles for servers can also be developed. ![]() ![]() Most of the GUI programs are created with Qt and they have a native looking interface, in which Qt is classified as a widget toolkit. Qt allows developers to design their own program’s user interface through a method that most end users are familiar with. Qt is regarded as a free and open source widget toolkit for creating GUIs as well as cross-platform applications that run on various software and hardware platforms such as Linux, Windows, macOS, Android or embedded systems – with little or no change in the underlying code base, while still being a native application with native capabilities and speed. Qt is currently being developed both by the Qt Company, a subsidiary of Digia, and the Qt Project, under open source governance, involving individual developers and firms. In August 2012, it was acquired from Nokia by Digia, a Finnish company. Qt was primarily developed by Trolltech, a Norwegian software company that was acquired by Nokia in 2008. Qt is a tool that facilitates the creation of GUIs. As computing evolved, graphical user interfaces became an integral part of any computer application. In fact, in the early days, the command line was the sole user interface for Linux programs. Hard core Linux users prefer the power of the command line. ![]()
