Qt provides support for the Symbian platform with integration to the S60 framework. If you are developing apps for the Symbian, Maemo or MeeGo platforms in most cases, you can use Qt under the free LGPL licensing option. Qt is cross-platform, and that means that you can use the code from one single code-base and rebuild for all supported platforms.
On top of all the tools and the API and class libraries that Qt offers, Qt provides you with added functionality for an optimized Symbian development experience.
Qt will detect which theme the phone is running and applies the style at runtime to your Qt application. The look and feel of your applications can also be easily customized in a fraction of the time and lines of code required for traditional UI styling with Qt Style Sheets.

Qt for Symbian is available under the Qt Commercial License, the LGPL v. 2.1 "LGPL") and the GPL v. 3.0. Symbian currently licenses their software products under either the Symbian Foundation License or the Eclipse Public License ("EPL"). While the LGPL and the EPL are not compatible and may not be combined on a file-by-file basis, they may be used in a common environment provided that the interaction between Qt and Symbian is limited to: dynamic linking, inter-process communication and data exchange. Therefore, most Symbian developers can use Qt for Symbian under the LGPL.
