Developing widgets - BENEFITS

Platform based on web technologyHTML + CSS + JavaScript

Lot’s of development environments available

“Background running” widgets running in

extended view

Rapid development and deployment across

most modern handsets

One app should be able to work across all

handsets

In our experience only packaging differs

between different target handsets

Developing widgets - TOOLS

Developing widgets - TOOLS

Developing widgets - Challenges

Current documentation is comprehensive yet lacks structure

Developing a widget with a good UE across devices with different displays and with different input

APIs still limited in terms of multimedia support

The lack of common/reusable controls and dialogs

Contact picker, Image picker, system stylesheets etc

Font sizes different than in the Opera Widget Manager and must therefore be optimized and tested for R1

Image scaling differs slightly

No extended / floating mode of the widget on s60

Runtime based on WebKit and not Opera Widget Manager

Important to test on both the H1 and M1 devices to get it right

Developing widgets – Porting to R1

Recommendations Get the JIL SDK - the object reference documentation is a very good start

Design for 480x800 but make sure that it will also scale well to 240x320 screens and landscape mode. CSS is your friend

Test on the device!Opera IS NOT WebkitparseInt( ‘010’ ) for Webkit and parseInt( ‘010’, 10 ) for Opera // for some reason webkit defaults to octal parsing

Recommendations

Progress indicators! You don’t think you need them, but you do

Network speed is not always as fast as you think on the device (User could be roaming or for some unimaginable reason not be on a Vodafone network)

Recommendations Don’t use pixel sizes - instead define your sizes in millimetersLooks awful on your PC but saves you lot’s of target device customization

#my-element {

font-size: 2mm;

-webkit-background-size: 20px 20px;

-o-background-size: 20px 20px;

}

#my-element {

font-size: 2mm;

-webkit-background-size: 20px 20px;

-o-background-size: 20px 20px;

}

That’s it
