qtopia上的简单程序见faq
qtopia是基于qte开发的， 包括应用和扩展的库。 看看这段qtopia较早版本1.6的简介：
Qtopia is a platform for embedded Linux devices. Qtopia provides the end-user with a set of core applications that are expected on modern embedded platforms such as PIM applications (Address Book, Calendar and Todo) and a Media Player.
Qtopia provides the developer with a clean object-oriented API to write applications for an embedded device. Most of the API presented to the developer is the same API offered by Trolltech for cross-platform development between Windows, Mac and the UNIX's. The same code can be shared and reused on all of these desktop platforms and now Qtopia is just another platform to run your great Qt applications.
The Qtopia platform encomposses both the software that runs on an embedded device and the software that runs on a end-users desktop. The software that runs on the desktop, called Qtopia Desktop, allows the user to input Qtopia application information on their desktop and synchronize their data between the embedded device and the desktop. Qtopia Desktop allows the developer to write plugins into the desktop to synchronize their information. Please refer to the Qtopia Desktop documentation for more information.
