    \title Qt Examples
    \brief The example programs provided with Qt.

    \previouspage Tutorials
    \contentspage How to Learn Qt
    \nextpage Qt Demonstrations

    Qt is supplied with a variety of examples that cover almost every aspect
    of development. They are not all designed to be impressive when you run
    them, but their source code is carefully written to show good Qt
    programming practices. You can launch any of these programs from the
    \l{Examples and Demos Launcher} application.

    These examples are ordered by functional area, but many examples often
    use features from many parts of Qt to highlight one area in particular.
    If you are new to Qt, you should probably start by going through the
    \l{Tutorials} before you have a look at the
    \l{mainwindows/application}{Application} example.

    In addition to the examples and the tutorial, Qt includes a
    \l{Qt Demonstrations}{selection of demos} that deliberately show off
    Qt's features. You might want to look at these as well.

    \section1 \l{Widgets Examples}{Widgets}
    \beginfloatleft
    \l{Widgets Examples}{\inlineimage widget-examples.png
    }

    \endfloat
    Qt comes with a large range of standard widgets that users of modern
    applications have come to expect. You can also develop your own custom
    widgets and controls, and use them alongside standard widgets.

    It is even possible to provide custom styles and themes for widgets that can
    be used to change the appearance of standard widgets and appropriately
    written custom widgets.

    \clearfloat
    \section1 \l{Dialog Examples}{Dialogs}
    \beginfloatleft
    \l{Dialog Examples}{\inlineimage dialog-examples.png
    }

    \endfloat
    Qt includes standard dialogs for many common operations, such as file
    selection, printing, and color selection.

    Custom dialogs can also be created for specialized modal or modeless
    interactions with users.

    \clearfloat
    \section1 \l{Main Window Examples}{Main Windows}
    \beginfloatleft
    \l{Main Window Examples}{\inlineimage mainwindow-examples.png
    }

    \endfloat
    All the standard features of application main windows are provided by Qt.

    Main windows can have pull down menus, tool bars, and dock windows. These
    separate forms of user input are unified in an integrated action system that
    also supports keyboard shortcuts and accelerator keys in menu items.

    \clearfloat
    \section1 \l{Layout Examples}{Layouts}
    \beginfloatleft
    \l{Layout Examples}{\inlineimage layout-examples.png
    }

    \endfloat
    Qt uses a layout-based approach to widget management. Widgets are arranged in
    the optimal positions in windows based on simple layout rules, leading to a
    consistent look and feel.

    Custom layouts can be used to provide more control over the positions and
    sizes of child widgets.

    \clearfloat
    \section1 \l{Item Views Examples}{Item Views}
    \beginfloatleft
    \l{Item Views Examples}{\inlineimage itemview-examples.png
    }

    \endfloat
    Item views are widgets that typically display data sets. Qt 4's model/view
    framework lets you handle large data sets by separating the underlying data
    from the way it is represented to the user, and provides support for
    customized rendering through the use of delegates.

    \clearfloat
    \section1 \l{Graphics View Examples}{Graphics View}
    \beginfloatleft
    \l{Graphics View Examples}{\inlineimage graphicsview-examples.png
    }

    \endfloat
    Qt is provided with a comprehensive canvas through the GraphicsView
    classes.

    \clearfloat
    \section1 \l{Painting Examples}{Painting}
    \beginfloatleft
    \l{Painting Examples}{\inlineimage painting-examples.png
    }

    \endfloat
    Qt's painting system is able to render vector graphics, images, and outline
    font-based text with sub-pixel accuracy accuracy using anti-aliasing to
    improve rendering quality.

    \clearfloat
    \section1 \l{Rich Text Examples}{Rich Text}
    \beginfloatleft
    \l{Rich Text Examples}{\inlineimage richtext-examples.png
    }

    \endfloat
    Qt provides powerful document-oriented rich text engine that supports Unicode
    and right-to-left scripts. Documents can be manipulated using a cursor-based
    API, and their contents can be imported and exported as both HTML and in a
    custom XML format.

    \clearfloat
    \section1 \l{Desktop Examples}{Desktop}
    \beginfloatleft
    \l{Desktop Examples}{\inlineimage desktop-examples.png
    }

    \endfloat
    Qt provides features to enable applications to integrate with the user's
    preferred desktop environment.

    Features such as system tray icons, access to the desktop widget, and
    support for desktop services can be used to improve the appearance of
    applications and take advantage of underlying desktop facilities.

    \clearfloat
    \section1 \l{Drag and Drop Examples}{Drag and Drop}
    \beginfloatleft
    \l{Drag and Drop Examples}{\inlineimage draganddrop-examples.png
    }

    \endfloat
    Qt supports native drag and drop on all platforms via an extensible
    MIME-based system that enables applications to send data to each other in the
    most appropriate formats.

    Drag and drop can also be implemented for internal use by applications.

    \clearfloat
    \section1 \l{Threading and Concurrent Programming Examples}{Threading and Concurrent Programming}
    \beginfloatleft
    \l{Threading and Concurrent Programming Examples}{\inlineimage thread-examples.png
    }

    \endfloat
    Qt 4 makes it easier than ever to write multithreaded applications. More
    classes have been made usable from non-GUI threads, and the signals and slots
    mechanism can now be used to communicate between threads.

    The QtConcurrent namespace includes a collection of classes and functions
    for straightforward concurrent programming.

    \clearfloat
    \section1 \l{Tools Examples}{Tools}
    \beginfloatleft
    \l{Tools Examples}{\inlineimage tool-examples.png
    }

    \endfloat
    Qt is equipped with a range of capable tool classes, from containers and
    iterators to classes for string handling and manipulation.

    Other classes provide application infrastructure support, handling plugin
    loading and managing configuration files.

    \clearfloat
    \section1 \l{Network Examples}{Network}
    \beginfloatleft
    \l{Network Examples}{\inlineimage network-examples.png
    }

    \endfloat
    Qt is provided with an extensive set of network classes to support both
    client-based and server side network programming.

    \clearfloat
    \section1 \l{Inter-Process Communication Examples}{Inter-Process Communication}
    \beginfloatleft
    \l{Inter-Process Communication Examples}{\inlineimage ipc-examples.png
    }

    \endfloat
    Simple, lightweight inter-process communication can be performed using shared
    memory and local sockets.

    \clearfloat
    \section1 \l{OpenGL Examples}{OpenGL} and \l{OpenVG Examples}{OpenVG} Examples
    \beginfloatleft
    \l{OpenGL Examples}{\inlineimage opengl-examples.png
    }

    \endfloat
    Qt provides support for integration with OpenGL implementations on all
    platforms, giving developers the opportunity to display hardware accelerated
    3D graphics alongside a more conventional user interface.

    Qt provides support for integration with OpenVG implementations on
    platforms with suitable drivers.

    \clearfloat
    \section1 \l{Multimedia Examples}{Multimedia Framework}
    \beginfloatleft
    \l{Multimedia Examples}{\inlineimage phonon-examples.png
    }

    \endfloat
    Qt provides low-level audio support on linux,windows and mac platforms by default and
    an audio plugin API to allow developers to implement there own audio support for
    custom devices and platforms.

    The Phonon Multimedia Framework brings multimedia support to Qt applications.

    \clearfloat
    \section1 \l{SQL Examples}{SQL}
    \beginfloatleft
    \l{SQL Examples}{\inlineimage sql-examples.png
    }

    \endfloat
    Qt provides extensive database interoperability, with support for products
    from both open source and proprietary vendors.
