<p>The Qtopia Core platform is a C++ framework for GUI and application development for embedded devices. It runs on a variety of processors, usually with Embedded Linux. Qtopia Core provides the standard Qt API for embedded devices with a lightweight windowing system.</p>

<p>In addition to the class library, Qtopia Core provides means for customizing and optimizing the final result: Memory consumption can be fine-tuned by compiling out features that are not used, and a number of options are available that reduce the memory and CPU requirements by making various trade-offs. Keyboard and pointer drivers can be specified, as weel as the font output's format. It is also possible to make use of accelerated graphics hardware.</p>
