RSS Reader</h1>
<div>
<p>
The RSS Reader example is the first complete, working widget that actually
does something useful that you will create using the WRTKit. It is quite a bit
more complex than the Hello World example, but then again it also contains
a lot more functionality.
</p>
<p>
For the Hello World widget we covered a lot of very fine details but for the
RSS Reader it is assumed that the reader already knows the basics of how to
create a widget, deploy it, test it, and so on. If you skipped the Hello World
tutorial and feel that you're not comfortable with the basics of creating
widgets yet then it's recommended that you go back and read the Hello World
widget tutorial first and then come back and continue with the RSS Reader.
</p>
<p>
The RSS Reader that we're going to build in this tutorial will have two views:
a main view that displays news items from an RSS feed and a settings view where
the user can configure what news feed should be displayed in the main view and
how often it should be updated from the Internet. We will let users choose from
a list of feeds that we will pre-configure. In principle you can use whatever
RSS feeds you want in your own widget but it's probably best to test first with
the ones we have in our example since they have been tested and known to work.
</p>
<p>
The actual news feed items will be displayed as a list of foldable content
panels on the main view. The panels allow the user to see the headline for each
piece of news and clicking on the headline will expand the news item so that the
actual story summary can be read. At the bottom of the summary we'll place a
link to the full story in a similar fashion to many other RSS reader applications.
</p>
<p>
We will also implement a couple of features to make the widget more user friendly.
For example the first time when the widget is started we'll go directly to the
settings view to let the user configure the widget before the first use. We'll
also show helpful information such as loading progress and any error messages in
notification popup windows. And of course all configuration settings will be
persistent so that the user doesn't have to re-configure the widget every time
its started.
</p>
<p>
In order to make the widget similar to other S60 applications, we will tweak
the softkeys and Options menu so that the settings view can be reached from the
menu and so that the right softkey will let the user go back from the settings
view to the main view. In the main view the right softkey will be used to exit
the widget. We will also allow the user to manually force a refresh of the news
items by adding a "Refresh" option to the options menu.
</p>
<p>
And last but not least, we'll implement the widget so that it will work in a
standards-compliant PC web browser such as Firefox. This will allow you to test
and debug the widget quickly as you develop it on your PC.
