## Detailed Description

The QVFbScreen class implements a screen driver for the virtual framebuffer.

Note that this class is only available in Qtopia Core. Custom screen drivers can be added by subclassing the QScreenDriverPlugin class, using the QScreenDriverFactory class to dynamically load the driver into the application, but there should only be one screen object per application.

The Qtopia Core platform provides a virtual framebuffer for development and debugging; the virtual framebuffer allows Qtopia Core programs to be developed on a desktop machine, without switching between consoles and X11.
