    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 

    82     \endfloat

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

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

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

    86 

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

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

    89     written custom widgets.

    95     }

    96 

    97     \endfloat

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

    99     selection, printing, and color selection.

   100 

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

   102     interactions with users.

   107     \l{Main Window Examples}{\inlineimage mainwindow-examples.png

   108     }

   109 

   110     \endfloat

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

   112 

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

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

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

   116

   118     \section1 \l{Layout Examples}{Layouts}

   119     \beginfloatleft

   120     \l{Layout Examples}{\inlineimage layout-examples.png

   121     }

   122 

   123     \endfloat

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

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

   126     consistent look and feel.

   127 

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

   129     sizes of child widgets.

   130 

   131     \clearfloat

   132     \section1 \l{Item Views Examples}{Item Views}

   133     \beginfloatleft

   134     \l{Item Views Examples}{\inlineimage itemview-examples.png

   135     }

   136 

   137     \endfloat

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

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

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

   141     customized rendering through the use of delegates.

   142

   144     \section1 \l{Graphics View Examples}{Graphics View}

   145     \beginfloatleft

   146     \l{Graphics View Examples}{\inlineimage graphicsview-examples.png

   147     }

   148 

   149     \endfloat

   150     Qt is provided with a comprehensive canvas through the GraphicsView

   151     classes.

   156     \l{Painting Examples}{\inlineimage painting-examples.png

   157     }

   158 

   159     \endfloat

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

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

   162     improve rendering quality.

   167     \l{Rich Text Examples}{\inlineimage richtext-examples.png

   168     }

   169 

   170     \endfloat

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

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

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

   174     custom XML format.

   181 

   182     \endfloat

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

   184     preferred desktop environment.

   185 

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

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

   188     applications and take advantage of underlying desktop facilities.

   194     }

   195 

   196     \endfloat

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

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

   199     most appropriate formats.

   200 

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

   207     }

   208 

   209     \endfloat

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

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

   212     mechanism can now be used to communicate between threads.

   213 

   214     The QtConcurrent namespace includes a collection of classes and functions

   215     for straightforward concurrent programming.

   222 

   223     \endfloat

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

   225     iterators to classes for string handling and manipulation.

   226 

   227     Other classes provide application infrastructure support, handling plugin

   228     loading and managing configuration files.

   257     Qt provides support for integration with OpenGL implementations on all

   258     platforms, giving developers the opportunity to display hardware accelerated

   259     3D graphics alongside a more conventional user interface.

   260

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

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

   273     custom devices and platforms.

   274

   284     Qt provides extensive database interoperability, with support for products

   285     from both open source and proprietary vendors.

   286 

   287     SQL support is integrated with Qt's model/view architecture, making it easier

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

   462 

   463     You can also develop your own custom widgets and controls, and use them

   464     alongside standard widgets.

   465 

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