Over the past five years Kitware has been transitioning to Qt for the development of Graphical User Interfaces (GUIs). Qt provides a powerful, open-source, cross-platform GUI toolkit that is developed through a strong community effort, and is widely adopted by software developers. By using Qt, developers are able to easily create GUIs that are familiar and intiutive to users, a key component when working with complex software.
Kitware transitioned ParaView to Qt in 2007 with the release of ParaView 3. In 2008, the Qt-based GUI front end to CMake was released. Kitware is also playing a key role in the transition of 3D Slicer to Qt with the forthcoming release of Slicer 4.
In recognition of the work in Qt, Kitware is pleased to announce that Marcus Hanwell and Rob Maynard have been named Qt ambassadors. This worldwide ambassador program honors Qt development by recognizing innovative work on Qt projects. In addition to the ambassadors, the program recognizes exceptional projects that use Qt, which are included in their Program Showcase. ParaView has recently been added to the showcase for its use of Qt not only for GUI visualization, but also for testing. The application is currently built with Qt 4.6.X and makes extensive use of custom models and views to handle the challenges that come with interacting with extremely large datasets. Other projects included in the showcase can be found on the Qt website.
