Qt Extended (named Qtopia before September 30, 2008) is an application platform for embedded Linux-based mobile computing devices such as personal digital assistants, video projectors and mobile phones. It was initially developed by The Qt Company, at the time known as Qt Software and a subsidiary of Nokia. When they cancelled the project the free software portion of it was forked by the community and given the name Qt Extended Improved. The QtMoko Debian-based distribution is the natural successor to these projects as continued by the efforts of the Openmoko community.[1][2]
