+ + 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. +
+ ++ + 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. +
+ ++ + 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. +
+ ++ + 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. +
+ ++ + 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. +
+ ++ + 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. +
+ ++ + 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. +
