This article covers some of the most common features and examples for porting cases, grouped by typical applications. Application sketches on the left side of this document illustrate common application types on iPhone and Android devices. UI component images on the right show some of the most common Qt Components used for building similar user experiences.

	QML ListView The ListView element provides a list or icon view onto a model. Read more QML Column The Column element provides a vertical layout for managing other QML elements. Read more Example: Dynamic linking Plug & Paint example demonstrates how to write Qt applications that can be extended through dynamically loaded plugins Open Example: Server Fortune Server example shows how to create a server in Qt for a simple network service Open Feature: State Framework State Machine framework provides an API and execution model that can be used to easily create UI functionality in Qt applications Read more Example: State transitions Event Transitions example shows how to use event transitions, a feature of The State Machine Framework Open	Symbian Qt Components portrait list
	Feature: View transform By applying a transformation to the view, you can easily add support for common navigation features such as zooming and rotating Read more Example: Drawing Basic Drawing example shows how to display basic graphics primitives in a variety of styles Open Example: Complex paths Painter Paths example shows how painter paths can be used to build complex shapes for rendering Open Feature: Draw path Draws the given painter path using the current pen for outline and the current brush for filling Read more Example: Path stroke Path Stroke example demonstrates various types of pens that can be used in Qt for paths Open Example: Advanced drawing Advanced Drawing example shows how to use advanced vector techniques to draw text using a QPainterPath Open	Common Symbian Qt Components buttons and text elements
	Example: XML with DOM QDomDocument enable developers to access the contents of XML files using a Document Object Model (DOM) API. Simple DOM Model example shows how to use it. Open Example: Image composition Image Composition example demonstrates the powerful image composition features supported in Qt. Open Example: Advanced composition Composition demo shows some of the more advanced composition modes supported by Qt Open Example: SVG viewer SVG Viewer example shows how to add SVG viewing support to applications for great scalable UIs and graphics. Open Example: State toggle Two-way button example shows how to use State Machine Framework to implement a logic that toggles state when a button is clicked Open Example: State animations Move Blocks example shows how to animate items in a QGraphicsScene using State Machine Framework with a custom transition. Open Example: State animations Application Chooser example shows how to use the Qt state machine and the animation framework. Open	Symbian Qt Components menu
	Class: Syntax highlighting Syntax highlighters are often used when the user is entering text in a specific format and help the user to read the text. Read more Example: Auto completer Auto-complete makes forms easier to use in mobile environments. Completer example shows how to provide string-completion facilities for an input widget based on defined data. Open Example: Custom completer Custom Completer is an other example of how to provide string-completion facilities for an input widgetOpen Example: Google suggest Google Suggest example demonstrates how to use the QNetworkAccessManager class to obtain a list of suggestions from the Google search engine as the user types into a QLineEdit Open Example: HTTP Client Qt provides network-transparent features for many media and content classes, but HTTP interaction is still the very basic of modern development. HTTP example demonstrates a how to fetch files specified by URLs from remote hosts Open Example: Web view Web view is a powerful tool for easy content handling. DOM Traversal example shows how to use the QWebElement class to access the structure of web view's HTML page Open Example: Web view selector Simple Selector example shows how to use QWebElement to access the Document Object Model (DOM) in a Web page Open	Symbian Qt Components dialog example
	QML GridView The GridView element allows displaying model data in a grid layout Read more Example: Sorting Custom Sort/Filter Model example illustrates how to perform advanced sorting and filtering in Qt Open Example: Localization Qt makes localization easy. Internationalization (I18N) example demonstrates Qt's support for translated text Open Example: Regexps Regular Expressions (RegExp) example shows how regular expressions in Qt are used with strings Open Example: SQL query Query Model example shows how to make customized versions of data obtained from a SQL query Open Example: SQL drill-down Drill Down example shows how to read data from a database as well as submit changes Open
	Example: Audio output QAudioOutput class provides an interface for sending audio data to an audio output device. Audio output example demonstrates use of this class. Open Example: Music player Music Player Example shows how to use Phonon - the multimedia framework that comes with Qt - to create a simple music player. Open Example: Bearer management Bearer Cloud example shows how to use the Bearer Management API to monitor the connectivity state of the local device, i.e. for loading offline content only while WLAN is available Open	Sample Symbian Qt Components application view
	Example: Audio input Audio Input example shows how to use QAudioInput class, that provides an interface for receiving audio data from an audio input device. Open Example: Gradients Gradients Example show how the various types of gradients can be used in Qt. Open
	Example: Drag'n'drop icons Drag'n'drop is the basic feature in modern user interfaces. Draggable Icons example shows how to drag and drop image data between widgets in Standard view Open Example: Drag'n'drop text Draggable Text example shows how to drag and drop textual data between widgets in Standard view Open Feature: Drag'n'drop Graphics View framework provides drag and drop support for the scene, and for each and every item Read more Example: Fetch more Fetch More example shows how two add items to an item view model on demand, commonly used by applications with a list view Open Example: FTP Client FTP Client example demonstrates how Qt can be used to list the available files on an FTP server and download them. Open Example: P2P chat Network Chat example demonstrates a stateful peer-to-peer Chat client that uses broadcasting with QUdpSocket and QNetworkInterface to discover its peers. Open
	Example: Inline-SVG Text Object example shows how to reduce layout work and insert an SVG file (such as status icons, emoticons etc) into a QTextDocument Open Example: Undo framework Undo Framework example shows how to easily implement advanced undo/redo functionality with the Qt undo framework Open Feature: QtScript QtScript module provides classes for making Qt applications scriptable. Read more Example: Qt scripting Qt Scripting example demonstrates how to implement the functionality of a calculator widget Open
	Example: Generated icons Qicon class in Qt creates automatically different button states from the given image object. Widget Icons example demonstrates how to use this great feature. Open Class: Grid layout QGraphicsGridLayout class provides a grid layout for managing widgets in Graphics View Read more Feature: Painter rotate Adjusting coordinate system on-the-fly makes drawing of custom layouts easier in some cases. QPainter's rotate functionality rotates the coordinate system the given angle clockwise. [1] The sketches were created with [Balsamiq Mockups].
