Qt 4.7.1 is available for QNX Neutrino
From the wikipedia:
"Qt (pronounced officially as cute /'kju?t/, though often incorrectly as Q.T. /'kju?'ti?/) is a cross-platform application framework that is widely used for developing application software with a graphical user interface (GUI) (in which cases Qt is classified as a widget toolkit), and also used for developing non-GUI programs such as command-line tools and consoles for servers. Qt is most notably used in Autodesk Maya, Google Earth, KDE, Adobe Photoshop Elements, OPIE, Skype, VLC media player, VirtualBox, and Mathematica, and by the European Space Agency, Siemens, Volvo, Walt Disney Animation Studios, Samsung, Philips, and Panasonic.
It is currently produced by Nokia's Qt Development Frameworks division, which came into being after Nokia's acquisition of the Norwegian company Trolltech, the original producer of Qt. Nokia announced that it is going to drop Symbian technologies and base their future smartphones on Microsoft platform instead in February 2011. One month later Nokia announced the sale of Qt's commercial licensing and professional services to Digia PLC, although Nokia will remain the main development force behind the framework. On 9th May, it was announced on the Qt Labs website that the groundwork was being laid for the next major version of Qt, with the expectation that Qt 5 would be released in 2012.
Qt uses standard C++ but makes extensive use of a special code generator (called the Meta Object Compiler, or moc) together with several macros to enrich the language. Qt can also be used in several other programming languages via language bindings. It runs on the major desktop platforms and some of the mobile platforms. It has extensive internationalization support. Non-GUI features include SQL database access, XML parsing, thread management, network support, and a unified cross-platform API for file handling.
Distributed under the terms of the GNU Lesser General Public License (among others), Qt is free and open source software. All editions support a wide range of compilers, including the GCC C++ compiler and the Visual Studio suite."
— "Qt is a cross-platform application and UI framework. Using Qt, you can write web-enabled applications once and deploy them across desktop, mobile, and embedded operating systems without rewriting the source code" —
This "write once, deploy across" feature is a key reason why many QNX customers, particularly those in the Medical and Industrial Automation industries, show interest in Qt. Mind you, it's not the only reason. Qt's rich cross-platform C++ class library, running on the QNX Neutrino RTOS, also allows device makers to:
– build advanced user interfaces from a rich set of standard and customizable GUI components
– visualize data in 3D with a tight integration with OpenGL
– increase designer & developer collaboration with Qt Quick, a complete UI creation kit
– take advantage of the Qt ecosystem
– leverage the reliability and real-time performance of the QNX Neutrino RTOS
