Carbide.ui Series 40 Theme Edition 6.0 released

Themes remain one of the most popular content items users add to their phones, and several theme developers have achieved over 1 million downloads. With Nokia Store continuing to grow, there is no better time to show your creative and artistic skills through an innovative and appealing theme. And the news gets even better: Carbide.ui Theme edition has just received a major update.

Among the changes is a redesigned theme creation wizard. In addition to creating themes from a template or copy of an existing theme, you can choose a phone model; then, Carbide.ui will automatically select the right template. This feature also keeps you up to date through an RSS feed from the device section of Nokia Developer, so you can start creating themes for the latest phones as soon as they are announced.

Packaging has also been simplified, with the packaging parameters automatically set in the updated packaging wizard. This means that in most cases packaging is just two clicks. In addition, when you use the phone model feature of the new theme wizard, the packaging wizard provides you with a list of the other phone models your theme will work on.

Also, significant improvements will now ensure that you are always up to date. For one, this new version of Carbide.ui automatically checks for software updates, which you install with a single click. For another, it advises you of new or updated theme template plug-ins as well. The new plug-in manager then enables you to install any new or updated plug-ins you want, without leaving Carbide.ui.

Other improvements include: support for defining 16-bit colour elements; the ability to export of a theme’s preview screens to a PDF file; and NFL (Flash Lite) content previews.

So if you want to exercise your creative side -- or if art and design are your bread-and-butter -- then you should be downloading Carbide.ui Series 40 Theme Edition today.

Optimize your apps for Nokia Belle

Upgrades to Nokia Belle software (also known as Symbian Belle) will start to roll out worldwide soon. Now you can optimize your current S^3 and Symbian Anna apps to make the most of the UI changes that Belle brings to a wide range of Nokia’s Symbian smartphones.

While many existing apps will be largely compatible with Belle from the start, we recommend that you first test your older apps with Nokia Belle and then address any compatibility issues you may find. Don’t have a Nokia Belle phone? No problem, you can use Nokia’s free Remote Device Access service to test your apps. Depending on the results, you may decide to make certain changes; then you can republish or update your app in Nokia Store to make the most of the new Belle software.

Also, if you develop new apps that use Belle-specific APIs, these apps will not work with phones that run S^3 or Symbian Anna. So you may also decide to limit the distribution of these applications to Belle-only phones.

Documentation about Nokia Belle compatibility is now available in the Nokia Developer Wiki. [Note: This Wiki article is a work in progress, and more details will be added soon.]

To learn more, watch this video showing a hands-on demo of the Symbian Belle UI:

QtInfo app reveals what’s under the hood

The free QtInfo app is perfect if you are a developer who needs to know what version of the Qt framework is running in a Nokia phone, or if you’re a geek who likes to know that level of detail. Launch the app to reveal the Qt version and build currently installed, with details tailored for developers. For example, the report below shows that Qt 4.7.4 is installed along with the list of installed modules. If you scroll down the screen you’ll see more details of the installation, including the versions of Qt Quick, OpenGL, and WebKit. The report includes information about audio, video, and image formats supported by the current installation. You’ll even see optional Qt Components installed from packages com.nokia.symbian, qt.labs.components, and qt.labs.components.native.

QtInfo also reveals information about the execution environment as seen by the Qt framework. You will see information about the country and language currently selected, available network interfaces and addresses, and information about local hardware including sensors, WiFi, Bluetooth, screen parameters, etc.

QtInfo adapts to the available environment, allowing it to work across a wide range of devices and installation configurations. For example, the screen shot above was coded in QML to take advantage of Qt Quick available in the Qt 4.7.4 installation. The following screen shot was built with QtWidgets for execution in older versions (Qt 4.6.4). If you run QtInfo on a Symbian device with no Qt framework installed, it will use Avkon components to report the lack of a Qt installation.

Once QtInfo acquires all the information, you can capture the report to Clipboard, Pastebin,  Email, or write it to a file on local mass-storage.

QtInfo is an open source application developed by Attila Csipa, Lauri Jaaskela and Lucian Tomuta.
