Qt for S60: QFriendFeed Example
This Qt C++ example application is a social networking application that integrates to a FriendFeed microblogging engine (http://friendfeed.com/). QNetworkAccessManager is used to access the FriendFeed RESTful API to retrieve and post XML data which is parsed using the SAX parser. Though optimised for various S60 screen layouts and input mechanisms, the UI relies on Qt cross-platform UI components. Their appearance is modified using CSS style sheets. The application has been tested to work on S60 3rd Edition and S60 5th Edition devices, with touch UI and keypad, and with Qt for S60 version Tower 4.5.2. Cross-platform support has been verified on Windows XP.

Qt for S60: QTabs Example
This Qt C++ application demonstrates how to implement a Qt for S60 application with tabs. Every tab has its own Options menu. Views (QWidgets) are stored in different tabs (QTabWidget). The application has a S60-style status and control pane and it supports screen orientation changes. The example has been tested to work on S60 3rd Edition and 5th Edition devices with Qt for S60 4.5.2 Tower release. Important classes: QTabWidget, QWidget, QMainWindow.

Qt for S60: QStackedWidget Example
This Qt C++ application provides a method to implement multiple views in Qt for S60 applications (an alternative to using tabs). Views (QWidgets) are stored in a stack (QStackedWidget). On application startup, only the default view is created in the stack. To optimise memory consumption, the other views are not created until they are needed. Every view has its own Options menu and CBA buttons with view-specific commands. The example has been tested to work on S60 3rd Edition and 5th Edition devices with Qt for S60 4.5.2 Tower release. Important classes: QWidget, QStackedWidget, QMainWindow.
Application --- Example; Base/System, Qt, Qt for S60, S60 --- S60 3rd Edition / S60 5th Edition, UI; English (en)
