==Qt on Symbian==
 
Qt is an integral part of the Symbian platform. The latest Symbian Belle phones include Qt as part of their firmware, and earlier phones have Qt support pre-installed as well. Symbian phones starting from S60 3rd Edition, Feature Pack 1 have had Qt support through downloadable modules. The relevant modules are automatically added via [http://www.developer.nokia.com/Community/Wiki/Nokia_Smart_Installer_for_Symbian Smart Installer] ''[developer.nokia.com]'', which checks for dependencies during installation of Qt-based applications.
 
Qt in Symbian is highly integrated to the operating system features, such as graphics and file system. The tight integration increases performance of Qt applications.
 
If you are developing apps for Symbian phones and the Nokia N9, in most cases, you can use Qt under the free <span class="caps">LGPL</span> 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.
 
==Qt <span class="caps">SDK</span>==
 
Development of Qt apps for Symbian phones is undertaken easily using the [http://qt.nokia.com/downloads Qt <span class="caps">SDK</span>] ''[qt.nokia.com]''. The current version (Qt <span class="caps">SDK</span> 1.2) offers features to build applications for Symbian Anna and Symbian Belle phones (as well as the Nokia N9 and desktop platforms) using Qt 4.7.4. Development for earlier versions of the Symbian platform and Qt are possible, using [https://www.developer.nokia.com/info/sw.nokia.com/id/84801bfe-8517-4287-9829-014c6f572127/Qt_SDK_1_1_2.html Qt <span class="caps">SDK</span> 1.1.2] ''[developer.nokia.com]'' available from the Nokia Developer website.

==Key Features of Symbian Development==
 
In addition to the Qt <span class="caps">SDK</span> and Qt <span class="caps">API</span>, Qt provides you with added functionality for an optimized Symbian development experience.
 
===Native Look and Feel===
 
You can use the Qt Quick Components to create UIs with the native look and feel of the latest Symbian UI. For more information on the UI, see the [http://www.developer.nokia.com/Resources/Library/Symbian_Design_Guidelines/index.html Symbian Design Guidelines] ''[developer.nokia.com]'' from Nokia Developer. For software development instructions, refer to the [http://doc.qt.nokia.com/qtquick-components-symbian-1.1/ Qt Quick Components] ''[doc.qt.nokia.com]'' reference.
 
===Graphics Features===
 
Qt for Symbian contains a powerful paint engine that provides features such as anti-aliasing, gradients, curves, and transparency. It also has animation support with timelines and easing curves. Graphics rendering is also fully hardware accelerated using OpenVG on Symbian Anna and Belle phones.
 
==Device Configurations==
 
Qt is supported in Symbian phones based on ''S60 3rd Edition, Feature Pack 1'' and later.
 
S60 3rd Edition Feature Pack 1 and 2 phones support ''Qt 4.6'' only. Qt is not pre-installed in these phones and it needs to be installed before an application is deployed. Installation on end user phones is done using [http://www.developer.nokia.com/Community/Wiki/Nokia_Smart_Installer_for_Symbian Smart Installer] ''[developer.nokia.com]'', which is built into applications created using the Qt <span class="caps">SDK</span>. All Nokia Store applications need to be packaged for compatibility with Smart Installer regardless to which Symbian phones or Qt releases the applications are targeted.
 
''S60 5th Edition'' phones don’t have Qt pre-installed, so Smart Installer deploys Qt if it’s not already available. In contrast to S60 3rd Edition, ''Qt 4.7.3'' with ''Qt Quick'' and ''Qt Mobility 1.1'' is supported for S60 5th Edition phones.
 
''Qt 4.7.4'' is supported for Symbian^3, Symbian Anna, and Symbian Belle (and later) phones only. Smart Installer deployment is used for Symbian^3 and Symbian Anna phones. Symbian Belle has this Qt version in firmware.
 
''Qt 4.8'' is available with Nokia Belle Feature Pack 1 release. This Qt version for Symbian platform brings several improvements regarding performance and stability. Please see [[Qt 4 8 Improvements in Symbian|Qt 4.8 – Improvements in Symbian Platform]] ''[qt.io]'' for more information.

Notes of the table:
 
* Hyphen “-” in the table means “not available”.
* '''[1]''' reference: Qt 4.7.4 bundle for Symbian^3 and Symbian has currently slightly older Qt WebKit 2.1.0 compared to Symbian Belle devices that have Qt WebKit 2.1.1.
* '''[2]''' reference: Symbian Belle will not receive Qt updates via Smart Installer, Qt will be updated in new OS releases (firmware updates).
* '''[3]''' reference: This firmware release is the basis of the [http://europe.nokia.com/symbian-belle#compatible Symbian Belle software update] ''[europe.nokia.com]'' to earlier Symbian^3 and Symbian Anna devices.
* '''[4]''' reference: Qt Mobility 1.2.1 provided by Smart Installer is minor update to Qt Mobility 1.2.0 in-built in Symbian Belle. Belle devices will get Qt Mobility 1.2.1 via firmware update.
* Qt WebKit has two different versioning schemes in Symbian: The Qt WebKit version and technical version. The technical version is given in brackets in the above table after Qt WebKit version. The technical version refers to the one used in Symbian <span class="caps">SIS</span> package and package registry of the device, and it is used in Smart Installer definitions (pkg files), whereas the Qt WebKit version is the one used e.g. in “Qt WebKit reference documentation:[http://doc.qt.nokia.com/4.7-snapshot/qtwebkit-guide.html” http://doc.qt.nokia.com/4.7-snapshot/qtwebkit-guide.html”] and in “WebKit.org site:[http://trac.webkit.org/wiki/QtWebKit”. http://trac.webkit.org/wiki/QtWebKit”.]
 
'''Note:''' The Qt <span class="caps">SDK</span> provides several versions of the Qt binaries that can be installed on Symbian devices (<span class="caps">SISX</span> files). '''It is important to understand that these files are not meant to be installed on devices which already have Qt in <span class="caps">ROM</span>'''. As per info in the table above, Symbian Belle and later has the Qt bundle in <span class="caps">ROM</span> and therefore its pacakages cannot be installed manually using the <span class="caps">SDK</span> provided files. Nor is there a need for that. You can use the [http://store.nokia.com/content/229667 QtInfo] ''[store.nokia.com]'' utility to query your device’s installed components and then install only the packages you notice to be missing (e.g. Notification <span class="caps">API</span>), or you can rely on the Smart Installer doing its smart determination of what needs to be installed.
 
For more information on which Qt module versions are supported in different Symbian phones, see the [http://doc.qt.nokia.com/qtcreator-snapshot/creator-developing-symbian.html Symbian development topic from the Qt Creator documentation] ''[doc.qt.nokia.com]''.
 
All Symbian phones supporting Qt provide for automatic switching between landscape and portrait mode, and touch screen and keypad input as appropriate. Qt is deeply integrated to the native Symbian OS and phone hardware features, such as hardware graphics acceleration.
 
===Cross-platform Development Using Qt Creator===
 
[[Image:qtcreator-screenshots.png|Qt Creator]]
 
[http://doc.qt.nokia.com/qtcreator-snapshot/index.html Qt Creator] ''[doc.qt.nokia.com]'' is a complete cross-platform <span class="caps">IDE</span> included in the Qt <span class="caps">SDK</span>. The <span class="caps">IDE</span> enables you to create, build, debug, and run Qt applications across all supported platforms. You can have a single project and deploy that to multiple phones: such as Symbian and the Nokia N9 (using the MeeGo 1.2 Harmattan target).
