"Qt is a cross-platform application and UI framework with APIs for C++ programming and Qt Quick for rapid UI creation.

  • Intuitive class libraries
  • Easy to use and learn
  • Produce highly readable, easily maintainable and reusable code

The Qt framework is emerging as a major development platform and is the basis of the KDE software community.


If any KDE or Qt dependent packages have been installed, Qt is already present. Otherwise, you can install qt from the [Extra] repository.

The previous version is also available in qt3 package.

Warning: Installing Qt3 affects Qt environments on your system. It may cause the compilation failure of Qt4 applications.

GTK+ and Qt

If you have GTK+ and Qt applications, their looks might not blend well. If you wish to make your GTK+ styles match your Qt styles please read Uniform Look for QT and GTK Applications.

Integrated Development Environments

There are several integrated development environments available for producing software using the Qt toolkit.
