Detailed Description

The QVNCScreen class implements a screen driver for VNC servers.

Warning: This function is not part of the public interface.

Note that this class is only available in Qt for Embedded Linux. Custom screen drivers can be added by subclassing the QScreen class, using the QScreenDriverFactory class to dynamically load the driver into the application.

The VNC protocol allows you to view and interact with the computer's display from anywhere on the network. See the The VNC Protocol and Qt for Embedded Linux{VNC protocol} documentation for more details.

The default implementation of QVNCScreen inherits QLinuxFbScreen, but any QScreen subclass, or QScreen itself, can serve as its base class. This is easily achieved by manipulating the VNCSCREEN_BASE definition in the header file.
