    55     \brief The example programs provided with Qt.

    56 

    57     \previouspage Tutorials

    58     \contentspage How to Learn Qt

    59     \nextpage Qt Demonstrations

    60 

    61     Qt is supplied with a variety of examples that cover almost every aspect

    62     of development. They are not all designed to be impressive when you run

    63     them, but their source code is carefully written to show good Qt

    64     programming practices. You can launch any of these programs from the

    65     \l{Examples and Demos Launcher} application.

    66 

    67     These examples are ordered by functional area, but many examples often

    68     use features from many parts of Qt to highlight one area in particular.

    69     If you are new to Qt, you should probably start by going through the

    70     \l{Tutorials} before you have a look at the

    71     \l{mainwindows/application}{Application} example.

    72 

    73     In addition to the examples and the tutorial, Qt includes a

    74     \l{Qt Demonstrations}{selection of demos} that deliberately show off

    75     Qt's features. You might want to look at these as well.

    81     \row

    82     \o \image widget-examples.png

    83     \o 

    84     Qt comes with a large range of standard widgets that users of modern

    85     applications have come to expect. You can also develop your own custom

    86     widgets and controls, and use them alongside standard widgets.

    87 

    88     It is even possible to provide custom styles and themes for widgets that can

    89     be used to change the appearance of standard widgets and appropriately

    90     written custom widgets.

    91 

    92     \o \image dialog-examples.png Dialogs

    93     \o 

    94     Qt includes standard dialogs for many common operations, such as file

    95     selection, printing, and color selection.

    96 

    97     Custom dialogs can also be created for specialized modal or modeless

    98     interactions with users.

   104     \row

   105     \o \image mainwindow-examples.png MainWindows

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

   107 

   108     Main windows can have pull down menus, tool bars, and dock windows. These

   109     separate forms of user input are unified in an integrated action system that

   110     also supports keyboard shortcuts and accelerator keys in menu items.

   111 

   112     \o \image layout-examples.png Layouts

   113     \o 

   114     Qt uses a layout-based approach to widget management. Widgets are arranged in

   115     the optimal positions in windows based on simple layout rules, leading to a

   116     consistent look and feel.

   117 

   118     Custom layouts can be used to provide more control over the positions and

   119     sizes of child widgets.

   124     \row

   125     \o \image itemview-examples.png ItemViews

   126     \o

   127     Item views are widgets that typically display data sets. Qt 4's model/view

   128     framework lets you handle large data sets by separating the underlying data

   129     from the way it is represented to the user, and provides support for

   130     customized rendering through the use of delegates.

   131 

   132     \o \image graphicsview-examples.png GraphicsView

   133     \o

   134     Qt is provided with a comprehensive canvas through the GraphicsView

   135     classes.

   141     \o \image painting-examples.png Painting

   142     \o

   143     Qt's painting system is able to render vector graphics, images, and outline

   144     font-based text with sub-pixel accuracy accuracy using anti-aliasing to

   145     improve rendering quality.

   146 

   147     \o \image richtext-examples.png RichText

   148     \o

   149     Qt provides powerful document-oriented rich text engine that supports Unicode

   150     and right-to-left scripts. Documents can be manipulated using a cursor-based

   151     API, and their contents can be imported and exported as both HTML and in a

   152     custom XML format.

   157     \row

   158     \o \image desktop-examples.png

   159     \o

   160     Qt provides features to enable applications to integrate with the user's

   161     preferred desktop environment.

   162 

   163     Features such as system tray icons, access to the desktop widget, and

   164     support for desktop services can be used to improve the appearance of

   165     applications and take advantage of underlying desktop facilities.

   166 

   167     \o \image draganddrop-examples.png DragAndDrop

   168     \o

   169     Qt supports native drag and drop on all platforms via an extensible

   170     MIME-based system that enables applications to send data to each other in the

   171     most appropriate formats.

   172 

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

   179     \o \image thread-examples.png

   180     \o

   181     Qt 4 makes it easier than ever to write multithreaded applications. More

   182     classes have been made usable from non-GUI threads, and the signals and slots

   183     mechanism can now be used to communicate between threads.

   184 

   185     The QtConcurrent namespace includes a collection of classes and functions

   186     for straightforward concurrent programming.

   187 

   188     \o \image tool-examples.png Tools

   189     \o

   190     Qt is equipped with a range of capable tool classes, from containers and

   191     iterators to classes for string handling and manipulation.

   192 

   193     Other classes provide application infrastructure support, handling plugin

   194     loading and managing configuration files.

   213     \o

   214     Qt provides support for integration with OpenGL implementations on all

   215     platforms, giving developers the opportunity to display hardware accelerated

   216     3D graphics alongside a more conventional user interface.

   217 

   218     \o \image phonon-examples.png

   219     \o

   220     Qt provides low-level audio support on linux,windows and mac platforms by default and

   221     an audio plugin API to allow developers to implement there own audio support for

   222     custom devices and platforms.

   223 

   224     The Phonon Multimedia Framework brings multimedia support to Qt applications.
