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 developed by Qt Software, a subsidiary of Digia, and when they cancelled the Qt Extended project, as it was free software, the community created a fork of it, the Qt Extended Improved project, and continued building. The QtMoko Debian-based distribution is the natural successor to these projects as continued by the efforts of the Openmoko community.
