Qt Quick Application Developer Guide for Desktop

Qt Quick Application Developer Guide for Desktop will familiarize you with the development of feature-rich applications that you can deploy onto various desktop platforms. This guide walks you through the implementation of a simple application called NoteApp inspired by the modern fluid UIs. NoteApp is a tool for managing daily notes which uses various advanced UI concepts including animations, database storage and Javascript usage for application logic rather than common well-known UI Elements used in desktop applications such as toolbars, menus and dialogs.

Qt SDK 1.1.4 update available

This 1.1.4 update of Qt SDK is very much focusing on bringing the SDK build targets to the level of the latest Symbian devices and the Nokia N9. It means that you can now start developing apps for these devices using:

• Qt 4.7.4 / Qt Quick 1.1 introducing among other things, right-to-left and pinch area support. These things are also supported by Qt Quick Components 1.1 update.


• Qt Mobility 1.2 which introduces new NFC (near field communication) and Bluetooth APIs, as well as quality improvements to the existing APIs.

Qt go open source

Development of Qt will be governed as a true open source project. The Qt Project governs the open source development of Qt. It allows anybody wanting to contribute to join the effort, through a meritocratic structure of approvers and maintainers.

All development will be driven by the people contributing to the project. To can learn more, visit the resources linked on this site and subscribe to our mailing-lists.

Visit new qt-project.org – a website where all development of Qt will be centered, providing the same infrastructure and processes for everybody that wants to contribute to Qt.

Visit Qt Developer Days from mobile

Qt Developer Days 2011 is the only event where you can learn directly from the developers who make Qt and from experienced Qt partners how you and your employer can make better use of Qt and the Qt SDK.

Now you can Visit Qt Developer Days from your mobile device:

A web version of the app has also been created for other smartphone platforms. Visit: m.qtdevdays2011.qt.nokia.com

Qt SDK 1.1.3 updated to align with the Nokia N9 release

It introduces the following improvements:

• Updated Harmattan target, Beta2, to correspond to the most recent public firmware release of Nokia N950 Developer Device. This version of the target is still considered experimental, but it can be used for developing apps for Nokia N9.


• Qt Creator 2.3.1, with support for app booster for N9 software and fixes for Symbian on-device debugging (CODA).


• Fix to ensure that Qt Quick components work in the Simulator for software targeting the Nokia N9 smartphone and Symbian phones.


• Symbian Complementary package improvements with an updated qmlviewer.sis for Qt 4.7.4 and NFC support in the QtMobility 1.2 sis file.

Qt SDK 1.1 RC released

Qt SDK 1.1 Release Candidate released. This is a major step towards the final Qt SDK 1.1, building on the beta we released a couple of weeks ago. The final Qt SDK will allow you to submit your Qt 4.7 based applications to the Ovi Store.

Summarizing the most important updates compared to the beta:

• Qt 4.7.3 is included for Desktop and Symbian
• Update to Qt Mobility 1.1.2
• Qt Assistant added as separate package (due to developer request)
• Installer can use system proxy on Linux
• Notification API moved from experimental to “Additional APIs”
• Several fixes for the Qt Simulator
• Several fixes for the installation/updating workflow

You are suggested to read the important article about that Qt 4.7 will not be supported for S60 3rd Edition. Please note that you are still able to create Qt applications for those targets based on Qt 4.6.

Qt SDK 1.1 beta released

Qt SDK 1.1 beta released, with Qt 4.7.2 a lot of improvements and fixes for Qt Quick have been published. Qt Mobility 1.1.1 includes updates for the supported platforms. Qt Creator 2.1 will allow you to create and design your QML applications from within the IDE nicely.

What has been missing so far is a nice and convenient way to get the whole package, namely the SDK.

The Qt SDK describes a merger between the Nokia Qt SDK, which provided a development environment for mobile targets, and the Qt Desktop SDKs. This allows you to develop applications for all platforms, which Qt supports. Compared to the Technology Preview we have included a significant amount of updates, namely:

• Qt 4.7.2 for Symbian ^1 and Symbian ^3
• Qt 4.7.2 for the Desktop
• Qt 4.7.2 for the Qt Simulator
• Qt Mobility 1.1.1 for Symbian^1, Symbian^3 and the Qt Simulator
• Qt Creator 2.1 final
• Qt Simulator 1.1 beta
• Updates to the Symbian Complementary package, providing the toolchain and build tools for the Symbian platforms

Qt Creator 2.1.0 released

With a few important fixes since the 2.1.0 release candidate, including adaptions of the mobile application project wizards and deployment related files, and updated documentation. Together with the Qt SDK 1.1 beta, Qt Creator 2.1.0 is released to provide a great experience.

The overall agenda for Qt Creator 2.1.0 was enhanced Qt Quick and mobile application support. And of course it got lots of improvements in all other areas as well.

Nokia CTO Rich Green talks about Qt

Nokia CTO Rich Green talks to Conversations readers about the futures of Qt, MeeGo and Symbian. With 150 million more Symbian devices planned for the next year, there’s still lots of work to be done in providing a great user experience for current Symbian users and for new owners. Plus ongoing suport for developers.

Nokia plans to ship 150 million Symbian devices over the next year, which is no small number, so developers will still have plenty of opportunity to reach 150 million extra people. Qt and QML is still very much alive and as Rich Green states “It is healthy and long lived, period”, with these platforms being used in MeeGo, with one of these devices being shipped this year.

Qt Labs China launched

It was launched a new Qt blog: Qt Labs China, it’s maintained by Qt developers and support/customer service engineers who speak Chinese.

If you speaks Chinese or want to interact with Chinese Qt developers, please head to Qt Labs China.

这是一个中文的Qt技术博客，我们都说中文，都就职于Nokia 公司的 Qt 部门，分别来自奥斯陆、北京和布里斯班的办公室，工作内容包括开发、技术支持与客户服务。

这个博客目前预定的形式与英文版本的 Qt 实验室 很相近，主要是向中文社区翻译和介绍一些最新和最值得关度的 Qt 技术及相关内容。我们也会根据大家的需要，发布一些原创的内容。所以欢迎给我们留言说说你想看到的内容。

为什么我们写这个博客？因为 2010 年增长最快的 Qt 社群就在中国，我们觉得有必要提供一个直接接触 Qt 开发过程、以及 Qt 专家的中文渠道，并获取来自中文社区的直接反馈，这个博客就是这样的一个渠道。

Other some Qt related blogs and forums in Chinese: Qt Everywhere, CuteQt, Qt CN.

Beginning Nokia Apps Development

Product Description

While media buzz regularly circulates around iPhone and Android, Nokia still leads the pack in terms of world market share. Symbian, for instance, remains the most widely used mobile operating system. With Nokia's open development platform, the opportunities available for mobile developers to target this vastly popular operating system are abundant and clear.

• Use Qt to target both platforms: Symbian, the most widely used mobile operating system in the world, as well as MeeGo, the Intel/Nokia platform for mobile devices.
• Develop HTML5 applications for both Symbian and MeeGo platforms that will run with little modification on other mobile platforms.
• Novice developers learn the basics of Qt with a mobile slant, giving them the ability to target both desktop and mobile platforms.

What you’ll learn

• How to do Qt basics
• What is QML or the Qt Markup Language
• What is Qt for Meego and how to use it
• and how to use it
• How to work with the Web Runtime
• Why mobile development is different
• How to port/support MeeGo and Symbian platforms

Who this book is for

This must have book is for mobile developers wanting to target the Meego and Symbian platforms (either as the sole platform or in cross-platform development), and existing mobile developers wanting to start using Qt.
