Questions tagged [qt5.1]

Qt is a cross-platform application development framework widely used for the development of GUI programs.

Qt (pronounced officially as cute (/kyut/) though commonly pronounced as Q.T. (/ˈkyu ti/)) is a cross-platform application development framework widely used for the development of GUI programs (in which case it is known as a widget toolkit), and also used for developing non-GUI programs such as console tools and servers. wikipedia

Qt was created by Trolltech, and is currently developed and maintained by Digia.

Current version:

The latest official release is 5.3.0. The major version indicates API compatibility.

Resources:

There is extensive official documentation (all classes) available on Qt's website, in addition to tutorials and examples. You will often see these tutorials and examples referenced in the questions and answers on this site. Qt also provides an integrated development environment named Qt Creator. Though it mainly aims at creating Qt applications, it can be used to create regular C++ applications too.

Tagging recommendation:

You will often see questions tagged specifically as , , or to indicate that the question is related to Qt 3.x, 4.x, or 5.x respectively. Qt 3.x is no longer supported and Qt 5.x has been released recently, so the default when version information is lacking is to assume version 4.x of the API.

Writing recommendation

Qt is a cross-platform application development framework, but QT (QuickTime) - is an extensible multimedia framework developed by Apple Inc.
