Slides on Nokia Widgets
Last April Nokia announced that there would be a new web runtime that would allow widgets to be run on S60 phones. Today, I came across a set of slides on SlideShare giving more more detail on how this will actually work.
In the short term, Nokia have implemented a limited run-time that won’t allow access to the much of the S60 platform API. This gets around some of the reservations I had about platform security when the runtime was first announced in that they have deferred this problem to some time in the future…
A widget includes a html, icon, css and javascript file…
Despite having limited access to the S60 API, it is possible to manipulate the phone menu items and access system information such as network information, battery status, the backlight and vibration. It’s interesting that asynchronous callbacks have also been implemented to allow for long running tasks without having to poll and waste battery power.
Widgets will have a .wyz file extension, install like normal SIS files and appear on the application list.
