The same article also shows how to use the Location API from Web Runtime Platform Services to retrieve your current location, and then using this data to get the appropriate map from Google Maps.

The article shows all the steps involved in the creation of the new Component, explaining all the necessary details to understand the whole process, passing by the setup of the Component file structure, the writing of the actual Component JS and CSS code, and the integration of the Component with the Guarana UI building process.

Purpose of the article is to give developers guidelines to create their own Components, integrating them with the Guarana UI Library. The component is also available on the Guarana UI online Components Browser.

The full article is available, as usual, on Forum Nokia Wiki: How to create a new Component for the Guarana UI Library Guarana.

Components and code snippets commonly found on standard JavaScript frameworks are quite always not suited for mobile devices, and result in poor or non-optimal results.

Finally, Forum Nokia has released a UI framework that promises to solve all these issues, by providing a complete, tested and cross-compatible set of ready-to-use components: Guarana UI!

The framework is really complete, counting more that 20 components, compatible with touch (S60 5th edition) and non touch devices (S60 3.2 and 3.1, with some exceptions for the 3.1).

Moreover, the framework includes some interesting features as asynchronous loading of resources, that is absolutely useful to optimize performances and memory usage within a widget.

To get started, Forum Nokia provides extensive documentation, a Quick Start guide and sample code to show how each component looks like and how it can be used.

Kudos to Forum Nokia developers, as their effort will definitely bring fresh air to all widgets’ developers out there! :)

The News Ticker component is useful to display informative messages within your Widget, without requiring too much space (and for this reason they’re particuparly suited for mobile devices’ displays).

Full implementation, source code and example Widget are available on Forum Nokia Wiki: News Ticker JavaScript component for Web Runtime.

This component allows to easily view, browse and pick the images stored in the device gallery. Full implementation, and instructions on how to use this component within your Web Runtime widget, is available on Forum Nokia Wiki:

This one allows to easily represent the network signal, with images that can be easily customized.

As for the previous one, you can find full implementation and an example widget on Forum Nokia Wiki: Web Runtime Network Signal JavaScript component.

While there are a lot of libraries and components that can be easily adapted and used within WRT Widgets, there are still not many components specifically tought and designed for WRT itself.

So, here is my first Web Runtime component: the WRT JavaScript Battery component, supporting both WRT 1.0 and 1.1.

You can view and download the full implementation from Forum Nokia Wiki: Battery JavaScript component for WRT 1.0 and 1.1.

Feedbacks are welcome! :)

With S60 5th edition, Web Runtime and Flash Lite gained access to Platform Services: this means that you can finally access application data, location, sensors and system information directly from your Flash Lite application or WRT widget.

Talking about Web Runtime, new Service APIs were introduced to let you integrate those functionality with simple JavaScript code.

Among the various concepts to learn when dealing with these APIs, there is the synchronous/asynchronous way of calling each single method: this, apart from being a difference from a programming point of view, brings to different approaches and results on your WRT Widget.

This “WRT Service API Synchronous and Asynchronous calls” article on Forum Nokia Wiki will guide through the details of these differences, explaining how to use both of them, and underlining possible advantages of the one over the other.

As always, any kind of feedbacks is welcome! :)
