    \brief The QtOpenGL module offers classes that make it easy to
    use OpenGL in Qt applications.

    OpenGL is a standard API for rendering 3D graphics. OpenGL only
    deals with 3D rendering and provides little or no support for GUI
    programming issues. The user interface for an OpenGL application
    must be created with another toolkit, such as Motif on the X
    platform, Microsoft Foundation Classes (MFC) under Windows, or Qt
    on both platforms.

    \note OpenGL is a trademark of Silicon Graphics, Inc. in
    the United States and other countries.

    The Qt OpenGL module makes it easy to use OpenGL in Qt applications.
    It provides an OpenGL widget class that can be used just like any
    other Qt widget, except that it opens an OpenGL display buffer where
    you can use the OpenGL API to render the contents.

    To include the definitions of the module's classes, use the
    following directive:

    \snippet doc/src/snippets/code/doc_src_qtopengl.qdoc 0

    To link against the module, add this line to your \l qmake \c
    .pro file:

    \snippet doc/src/snippets/code/doc_src_qtopengl.qdoc 1

    The Qt OpenGL module is implemented as a platform-independent Qt/C++
    wrapper around the platform-dependent GLX (version 1.3 or later),
    WGL, or AGL C APIs. Although the basic functionality provided is very
    similar to Mark Kilgard's GLUT library, applications using the Qt
    OpenGL module can take advantage of the whole Qt API for
    non-OpenGL-specific GUI functionality.

    The QtOpenGL module is part of the \l{Qt Full Framework Edition} and the
    \l{Open Source Versions of Qt}. It is available on Windows, X11, and Mac OS X.
    \l{Qt for Embedded Linux and OpenGL} supports OpenGL ES (OpenGL for Embedded Systems).
    \note To be able to use the OpenGL API in \l{Qt for Embedded Linux}, it must be
    integrated with the Q Window System (QWS). See the
    \l{Qt for Embedded Linux and OpenGL} documentation for details.

    \title QtOpenVG Module
    \since 4.6
    \contentspage All Qt Modules
    \previouspage QtOpenGL
    \nextpage QtScript
    \ingroup modules

    \brief The QtOpenVG module is a plugin that provides support for
    OpenVG painting.

    OpenVG is a standard API from the
    \l{http://www.khronos.org/openvg}{Khronos Group} for accelerated
    2D vector graphics that is appearing in an increasing number of
    embedded devices.

    OpenVG support can be enabled by passing the \c{-openvg} option
    to configure. It is assumed that the following qmake variables
    are set to appropriate values in the qmake.conf file for your
    platform:

    \list
    \o QMAKE_INCDIR_OPENVG
    \o QMAKE_LIBDIR_OPENVG
    \o QMAKE_LIBS_OPENVG
    \endlist

    Most OpenVG implementations are based on EGL, so the following
    variables may also need to be set:

    \list
    \o QMAKE_INCDIR_EGL
    \o QMAKE_LIBDIR_EGL
    \o QMAKE_LIBS_EGL
    \endlist

    See \l{qmake Variable Reference} for more information on these variables.

    Two kinds of OpenVG engines are currently supported: EGL based,
    and engines built on top of OpenGL such as
    \l{http://sourceforge.net/projects/shivavg}{ShivaVG}.
    EGL based engines are preferred.

    Once the graphics system plugin has been built and installed,
    applications can be run as follows to use the plugin:

    \code
    app -graphicssystem OpenVG
    \endcode

    If ShivaVG is being used, then substitute \c ShivaVG instead of
    \c OpenVG in the line above.

        components that application developers may find useful.

    \brief The QtDesigner module provides classes that allow you to
    create your own custom widget plugins for Qt Designer, and classes
    that enable you to access Qt Designer's components.

    In addition, the QFormBuilder class provides the possibility of
    constructing user interfaces from UI files at run-time.

    following directive:

    \ingroup modules

    \brief The QtUiTools module provides classes to handle forms created 
    with Qt Designer.

    These forms are processed at run-time to produce dynamically-generated
    user interfaces. In order to generate a form at run-time, a resource
    file containing a UI file is needed. Applications that use the
    form handling classes need to be configured to be built against the
    QtUiTools module. This is done by including the following declaration
    in a \c qmake project file to ensure that the application is compiled
    and linked appropriately.

    \snippet doc/src/snippets/code/doc_src_qtuiloader.qdoc 0

    A form loader object, provided by the QUiLoader class, is used to
    construct the user interface. This user interface can
    be retrieved from any QIODevice; for example, a QFile object can be
    used to obtain a form stored in a project's resources. The
    QUiLoader::load() function takes the user interface description
    contained in the file and constructs the form widget.

    To include the definitions of the module's classes, use the following
    directive:

    \snippet doc/src/snippets/code/doc_src_qtuiloader.qdoc 1

    \note These classes are part of the \l{Open Source Versions of Qt} and
    \l{Qt Commercial Editions}{Qt Full Framework Edition} for commercial

    \brief The QtDBus module is a Unix-only library that you can use
    to perform Inter-Process Communication using the \l{Introduction to
    D-Bus}{D-Bus} protocol.

    Applications using the QtDBus module can provide services to
    other, remote applications by exporting objects, as well as use
    services exported by those applications by placing calls and
    accessing properties.

    The QtDBus module provides an interface that extends the Qt \l
    {signalsandslots.html}{Signals and Slots} mechanism, allowing one
    to connect to a signal emitted remotely as well as to connect a
    local signal to remote slot.

    To use this module, use the following code in your application:

    \snippet doc/src/snippets/code/doc_src_qtdbus.qdoc 0

    If you're using qmake to build your application, you can add this
    line to your .pro file to make it link against the QtDBus
    libraries:

    \snippet doc/src/snippets/code/doc_src_qtdbus.qdoc 1

    \note The source code for this module is located in the \c{src/qdbus}
    directory. When installing Qt from source, this module is built when Qt's
    tools are built.

    how to use this module.
