Qt (Qt) series of books home and headers written in C ++ with the programmer or Mac that allows easy development of application software. Quot includes several classes for working with the graphic interface , multimedia, database tools, networking , and more. Quotes written with Keith’s software are able to reconcile using a CipolisPlace language compiler for a range of operating systems, including GNU / Linux (desktop and portable devices), Windows , Windows CE, and Macawas. Thus, carrying software written without the changes in the text of the code is possible. Quotes can be used in many programming languages such as C ++, Java, and Python.
Qt is a multi-platform framework for development.The software is mostly used to create GUI applications. But after version 4, it is also possible to create text applications. The greatest use of Kyoto in the KDE graphical interface is one of the most important Linux graphics environments. Many software applications such as Opera, Google Earth, Skype, Qtopia, etc. are also created by this tool. Quotes are available on most operating systems such as Linux, Windows, Mac, and certain systems such as PDAs and Smartphones.
It uses its own internal engine to create objects and windows. At the same time, Quetts on each operating system generate programs that are exactly the same as the appearance of the same operating system or so-called native. Its core and its interior include very large bookshops in most areas such as the database, network , file system, Internet , and more. Quot also includes a very powerful and simple graphic designerthat makes programming and creating windows extremely easy and quick to implement. All Qt versions support a wide range of compilers, including GCC and Microsoft Visual Studio.
