It is not intended to be a comprehensive - guide to Qt's features. - - \section1 Fundamental Technologies in Qt - - Qt is built upon a set of core technologies, provided by the \l QtCore - and \l QtGui modules. These include the following: - - \list - \o \l{The Tulip Container Classes}, a set of template container classes. - \o \l{The Arthur Paint System}, the Qt 4 painting framework. - \o \l{The Interview Framework}, a model/view architecture for item views - and the \l{QtSQL Module}, which also uses this architecture. - \o \l{The Scribe Classes}, a framework for creating text documents, - performing low-level text layout and writing OpenDocument files. - \o A collection of \l{Qt Widget Gallery}{common desktop widgets}, styled - to fit in on each supported platform. - \o \l{The Qt 4 Main Window Classes}, a main window, toolbar, menu, and - docking architecture. - \o The \l{Graphics View} framework provides a canvas for producing - interactive graphics. - \o The \l{QtNetwork Module} provides support for TCP, UDP and local - sockets that are integrated with Qt's event model, including support - for Secure Socket Layer (SSL) communications, - \l{QNetworkProxy}{network proxy} servers and - \l{Bearer Management}{network bearer management}. - \o Enhanced \l{qt4-threads.html}{thread support} allows - \l{Signals & Slots}{signal-slot} connections across threads and - per-thread event loops. - Additionally, \l{Thread Support in Qt}{a framework for concurrent programming} - using Qt paradigms makes common threading tasks easier. - \o A \l{resource system} for embedding images and other resource files - into executable files makes it easier to deploy applications. - \o A \l{QTestLib Manual}{unit testing framework} for Qt applications and - libraries. - \endlist - - The mature classes provided by these technologies have been used to build - robust, cross-platform desktop applications. They are augmented by a number - of additional technologies and improvements that have appeared over the - lifetime of Qt 4. - - \section1 Graphical User Interfaces - - \div{class="float-right"} - \inlineimage gtk-tabwidget.png - \enddiv - \div{class="float-right"} - \inlineimage gtk-progressbar.png - \br - \inlineimage gtk-checkbox.png - \br - \inlineimage plastique-combobox.png - \br - \inlineimage plastique-radiobutton.png - \enddiv - - Alongside the support for traditional desktop user interfaces, Qt includes - support for declarative UI development with \l{Qt Quick}, a set of - technologies for creating fluid, dynamic user interfaces. A starting point - for exploring this approach can be found in the \l{Introduction to Qt Quick} - guide. - - Qt provides a range of standard user interface elements, called widgets, - for each supported platform. Widgets can be used as containers for other - widgets, as windows, and as regular controls that the user interacts with. - Where the platform supports it, widgets can be made to appear partially - transparent, and may be styled with \l{Qt Style Sheets}. - - Support for \l{QTouchEvent}{touch input} and \l{Gestures Programming}{gestures} - enable widgets to be used to create intuitive user interfaces for - touch-enabled devices. - - User interfaces can also be created dynamically at run-time with the - features provided by the \l{QtUiTools} module. - - A selection of available widgets are shown in the \l{Qt Widget Gallery}. - An introduction to the concepts behind widgets can be found in the - \l{Widgets Tutorial}. - - \clearfloat - \section1 Painting, Printing and Rendering - - \div{class="float-left"} - \inlineimage qpainter-affinetransformations.png - \enddiv - - Widgets are just one of many kinds of paint device that Qt can render onto. - This support for unified painting makes it possible for applications to use - the same painting code for different tasks, as well as allowing Qt to be - extended to support additional file formats. - - Qt provides support for common bitmap image formats, - \l{QtSvg Module}{Scalable Vector Graphics} (SVG) drawings and animations, - Postscript and Portable Document Format (PDF) files. Postscript and PDF are - integrated with \l{Printing with Qt}{Qt's printing system}, which also - allows printed output to be previewed. - - Interactive graphics can be created with the - \l{The Animation Framework}{animation framework}, allowing animations to be - used with both widgets and graphics items. Animations can be used with the - \l{The State Machine Framework}{state machine framework}, which provides a - way to express application logic and integrate it with the user interface. - Animations can be enhanced with a collection of - \l{QGraphicsEffect}{graphics effects} that operate on graphics items and - can be applied individually or combined to create more complex effects. - - Qt supports integration with \l{QtOpenGL}{OpenGL} on a number of levels, - providing convenience functions for handling textures and colors, as well - as providing support for pixel and sample buffers. Future support for - higher level 3D integration is provided by Qt3D enablers which include - \l{QMatrix4x4}{matrix multiplication}, \l{QQuaternion}{quaternions}, and an - API for \l{QGLShader}{vertex and fragment shaders}. - - Two APIs are provided for multimedia. The - \l{Phonon Overview}{Phonon Multimedia Framework} has traditionally been - used on desktop platforms. A set of - \l{QtMultimedia Module}{multimedia services} provides low-level access to - the system's audio system and is often used on mobile devices. - - \clearfloat - \section1 Infrastructure - - \div{class="float-right"} - \inlineimage qtscript-context2d.png - \enddiv - - Facilities for Inter-Process Communication (IPC) and Remote Procedure - Calling (RPC) mechanisms are available on platforms that support the - \l{intro-to-dbus.html}{D-Bus} message bus system. - - An \l{Undo Framework}{Undo framework} based on the - \l{Books about GUI Design#Design Patterns}{Command pattern} is designed to - enable a consistent approach to handling data in editing applications. - - The \l{QtScript} and \l{QtScriptTools} modules provide support for - application scripting and debugging using the ECMAScript language. - - The \l{QtHelp Module} provides the foundations of an interactive help - system that can be used in conjunction with Qt Creator or integrated into - applications directly. - - XML handling is supported in a number of places in Qt. The \l QtCore module - provides classes for reading and writing XML streams. The \l QtXmlPatterns - module includes XQuery, XPath and XSLT support, providing facilities for - XML processing beyond that supported by the QtXml module, which contains - SAX and DOM parsers. XML schema validation in the QtXmlPatterns module - covers large parts of version 1.0 of the specification. - - \clearfloat - \section1 Web Client Integration - - Integration between \l{Webkit in Qt}{Qt and WebKit} makes it possible for - developers to use a fully-featured Web browser engine to display documents - and access online services. Developers can access the browser's environment - to create documents and run scripts within one or more browser widgets. - - A \l{QWebElement}{DOM access API} for QtWebKit provides a cleaner and safer - way to access elements and structures of Web pages without the use of - JavaScript. - - \section1 Further Reading - - Many of the technologies mentioned here, as well as other, more specific - features, are listed in the \l{What's New in Qt 4} document. A complete - list of Qt's modules can be found on the \l{All Modules} page, which - also includes more domain-specific technologies. - - The tools that are supplied with Qt are covered by the listing in the - \l{Qt's Tools} document. -*/ |
