# Qtopia Core

Qtopia Core 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 window system.

Qtopia Core applications write directly to the framebuffer, eliminating the need for the X Window System and saving memory. The Linux framebuffer is enabled by default on all modern Linux distributions. For information on older versions, see http://en.tldp.org/HOWTO/Framebuffer-HOWTO.html. For development and debugging purposes, Qtopia Core provides a virtual framebuffer. It is also possible to run an application using the VNC protocol.
