7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	34	the news items. The majority of that code is in the FeedUpdateBroker.js file
7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	35	in a JavaScript class called FeedUpdateBroker. We'll only be using one single
7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	36	method from that class: fetchFeed(). But how do we hook that up to our widget?

7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	42	that runs once a second. There we'll need an if-clause that checks if it's time
7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	43	to update the feeds, if another update is already going on, if we have a valid URL
7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	44	that we can fetch and if we're in the main view. If all of these tests tell us
7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	45	that it's time to update the feed, we'll check if the feed update was manually

7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	48	dialog. Next we'll create a new instance of the FeedUpdateBroker class and call
7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	49	the fetchFeed() method to start the AJAX-based RSS feed update. We need to pass
7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	50	two arguments to this method: the feed URL that we have in the feedURL variable
7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	51	and a callback function that should be called when the update is completed.

7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	70	theory we shouldn't do this until the feed update completes since there is a risk
7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	71	that we do two updates at the same time. But because we're adding a check to
7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	72	only do feed updates if another update isn't on-going this risk isn't actually
7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	73	real. Now that we have a plan for how to update the feed, let's write the code.
7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	74	First we need to declare a variable for the feed update broker instance that

7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	152	replace it with the one that we asked it to show. If the status is "ok" then we'll
7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	153	call hideNotification() in the user interface manager. This will hide the progress

7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	611	The RSS Reader tutorial has taught us several things. We have learned to create a widget

7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	613	We used the SelectionList, SelectionMenu and FormButton controls in our settings view,
7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	614	and in the main view we used the ContentPanel control that allowed us to add our own

7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	616	we styled with CSS rules. We have learned to modify a view while the widget runs by adding
7848c135d915 Fixed 2046 - WRTKit Help. Renamed package for consistency. tasneems@symbian.org parents: diff changeset	617	and removing controls. And we have learned how to separate our widget code so that the
