    \title The VNC Protocol and Qt for Embedded Linux
    \ingroup qt-embedded

    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{Qt for Embedded Linux} application using the VNC protocol, the
    \l{Qt for Embedded Linux} library must be configured and compiled with the
    \c -qt-gfx-vnc option:

    \snippet doc/src/snippets/code/doc.src.emb-vnc.qdoc 0

    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 Qt for Embedded Linux
    Applications}{running applications} documentation for
    details). When runnng the application, use the \c -display option
    to specify the VNC server's driver. For example:

    \snippet doc/src/snippets/code/doc.src.emb-vnc.qdoc 1

    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:

    \snippet doc/src/snippets/code/doc.src.emb-vnc.qdoc 2

    \l{Qt for Embedded Linux} 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.

    \o \bold {The Virtual Framebuffer}

    The \l{The 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.
