    \title The VNC Protocol and Qtopia Core
    \ingroup qtopiacore

    VNC (Virtual Network Computing) software makes it possible to view
    and interact with one computer (the "server") from any other
    computer or mobile device (the "viewer") anywhere on a network.

    To run a \l {Qtopia Core} application using the VNC protocol, the
    \l {Qtopia Core} library must be configured and compiled with the
    \c -qt-gfx-vnc option:

    \code
        cd path/to/Qtopia/Core
        ./configure -qt-gfx-vnc
        make
    \endcode

    Then start a server application (i.e. construct a QApplication
    object with the QApplication::GuiServer flag or use the -qws
    command line parameter. See the \l {Running Qtopia Core
    Applications}{running applications} documentation for
    details). When runnng the application, use the \c -display option
    to specify the VNC server's driver. For example:

    \code
        cd path/to/Qtopia/Core/examples/widgets/analogclock
        ./analogclock -qws -display VNC:0
    \endcode

    To interact with the application over the network, run a VNC
    client pointing to the machine that is running the server
    application. VNC clients are available for a vast array of display
    systems: X11, Windows, Amiga, DOS, VMS, and dozens of others.  For
    example, using the X11 VNC client to view the application from the
    same machine:

    \code
        vncviewer localhost:0
    \endcode

    \l {Qtopia Core} will create a 640 by 480 pixel display by
    default. Alternatively, the QWS_SIZE environment variable can be
    used to set another size, e.g. \c QWS_SIZE=240x320.

    \table
    \row
    \o \bold {The Virtual Framebuffer}

    The \l {Qtopia Core's Virtual Framebuffer}{virtual framebuffer} is
    an alternative technique recommended for development and debugging
    purposes.

    The virtual framebuffer emulates a framebuffer using a shared
    memory region and the \c qvfb tool to display the framebuffer in a
    window.

    Its use of shared memory makes the virtual framebuffer much faster
    and smoother than using the VNC protocol, but it does not operate
    over a network.
