\title QML Applications
\brief Essential documentation for QML application developers
QML is a declarative language that allows user interfaces to be described in
terms of their visual components and how they interact and relate with one
another. It is a highly readable language that was designed to enable
components to be interconnected in a dynamic manner, and it allows components to
be easily reused and customized within a user interface. Using the \c QtQuick
module, designers and developers can easily build fluid animated user interfaces
in QML, and have the option of connecting these user interfaces to any back-end
C++ libraries.
\section2 What is QML?
QML is a user interface specification and programming language.
It allows developers and designers alike to create highly performant, fluidly
animated and visually appealing applications. QML offers a highly readable,
declarative, JSON-like syntax with support for imperative JavaScript
expressions combined with dynamic property bindings.
The QML language and engine infrastructure is provided by the \l {Qt QML} module.
For in-depth information about the QML language, please see the
\l{Qt QML} module documentation.
The following pages contain more information about QML:
\list
\li \l{First Steps with QML} - begin using QML with these examples
\li \l{Qt Creator: Creating Qt Quick Projects}{Creating Qt Quick Projects in Qt Creator}
\li \l{The QML Reference} - reference about the QML constructs and features
\li \l{qml-codingconventions.html}{QML Coding Conventions}
\li \l{Glossary of QML Terms}
\endlist
\section2 What is Qt Quick?
Qt Quick is the standard library of types and functionality for QML. It
includes visual types, interactive types, animations, models and views,
particle effects and shader effects. A QML application developer can get
access to all of that functionality with a single import statement.
The \c QtQuick QML library is provided by the \l{Qt Quick} module.
For in-depth information about the various QML types and other functionality
provided by Qt Quick, please see the \l{Qt Quick} module documentation.
\section1 QML User Interfaces
For creating or customizing graphical user interfaces, Qt Quick adds visual
types, animation types, and other QML types in addition to the standard QML
types from Qt QML. \l{Qt Creator: Using Qt Quick Designer}{Qt Quick Designer}
is integrated within Qt Creator and supports \c{QtQuick 2} from Qt Creator
version 2.7 and onwards.

\li \l{qtquick-usecase-userinput.html}{Responding to User Input in QML}
\li \l{qtquick-usecase-animations.html}{Animations in QML}
\li \l{qtquick-usecase-text.html}{Displaying Text in QML}
\li \l{qtquick-usecase-layouts.html}{Layouts in QML}
\li \l{qtquick-usecase-styling.html}{Style and Theme Support}
\li \l{qtquick-usecase-integratingjs.html}{Integrating JavaScript in QML}
\li \l{Scalability}
\endlist
\section2 Buttons, Menus, and other Controls
For a set of basic UI controls, the \l{Qt Quick Controls} module implements
several controls such as buttons, menus, and views. These controls mimic the
native behavior found in different platforms such as Windows, OS X, and Linux.
\list
\li \l{Qt Quick Controls Overview}
\li \l{Qt Quick Controls Styles}{Styles}
\li \l{Qt Quick Dialogs}{Dialogs}
\li \l{Qt Quick Layouts}{Layouts}
\endlist
\section2 Special Effects
Several Qt modules provide types for creating special effects in applications.
Their respective pages contain more information about specific uses.
\list
\li \l{Using the Qt Quick Particle System}{Particle Effects}
\li \l{Graphical Effects} - for creating image composition effects.
\endlist
\section2 Viewing Web Content in QML Applications
The QML type, \l{WebView}, renders and displays dynamic web content. It can load
a URL or an HTML string. To read more about WebView and view code samples, visit
the \l{Qt WebKit} page.
\section2 Sensors, Gestures, and Touch Interfaces
The \l{Qt Sensors} module allows applications to read information from
sensors such as accelerometers and tilt sensors. There is a common QML API for
different platforms and can be extended in C++.
\list
\li \l{Qt Sensors QML Types}
\li \l{Qt Sensors Examples}
\li \l{Compatibility Map} - lists support level for different mobile platforms
\endlist
\section1 Multimedia Content
The \l{Qt Multimedia} module enables applications to handle various media
content with a convenient set of QML types. These QML types can be extended
in C++.
\list
\li \l Multimedia
\list
\li \l{Audio Overview}
\li \l{Video Overview}
\li \l{Camera Overview}
\li \l{Radio Overview}
\li \l{Qt Audio Engine QML Types}{Qt Audio Engine} - for 3D positional audio
playback and content management.
\endlist
\endlist
\section1 Mobile Devices
Several Qt modules provide QML APIs for networked and mobile devices. The QML
types access Bluetooth, Near-Field Communications (NFC), and GPS-enabled
devices.
\list
\li \l{Qt Positioning}
\li \l{Qt Bluetooth}
\li \l{Qt NFC}
\endlist
For more information, visit the \l{Networking and Connectivity} and
\l{Mobile APIs} pages.
\section1 Code Samples and Demos
To learn more about uses of QML code, there are several code samples which show
how QML types are used. In addition, there are several demos which show how
QML code is used in applications.
\list
\li \l{Getting Started Programming with Qt Quick} - a tutorial showing the creation of a simple QML text editor.
\li \l{Qt Quick Examples and Tutorials}
\endlist
\section1 Advanced Application Development Topics
\list
\li \l{qtquick-deployment.html}{Deploying QML Applications}
\li \l{qtquick-performance.html}{Performance Considerations and Suggestions}
\li \l{qtquick-internationalization.html}{Internationalization and Localization}

\li \l{qtquick-debugging.html}{Debugging QML Applications}
\li \l{qtquick-qtquicktest.html}{Qt Quick Test: QML Unit Testing Framework}
\endlist
\endlist
\section1 Other QML Modules
Qt Quick only provides basic visual types and much of Qt's functionality is
exposed to QML through other modules. If you require the functionality of those
modules, you should browse their QML documentation.
The \l{All QML APIs by Module} contains a list of all QML modules
in Qt 5.
