adding new feed filters

hi,
i have added the extension point ItemViewUIAdvisor to create my
ItemViewerFilter and to add this to client's user interface.
now i'm confused about filter behaviour (i'm only interested to new
feed subscription created by user):


public class FeedFilterExtension implements IItemViewUIAdvisor {

ItemViewerFilter facebookFilter;
FeedFilter ff;

public void configure(ItemViewUIConfigurer arg0)
{

facebookFilter=new ItemViewerFilter(ff, "fb",
"Facebook",1);
facebookFilter.setEnabledByDefault(true);
arg0.addFilter(facebookFilter);

}

}



in my filter I need to exclude some specific feeds from the feedreader
and that is done implementing the select method in a classe that
extends ViewerFilter...

public class FeedFilter extends ViewerFilter  {
	@Override
	public boolean select(Viewer viewer, Object parentElement,
Object     element) {
return true;
	}
}

how can i get all feeds to feedreader and use these in select method,
utilizing a casting with the element argument?

I will appreciate any hints, snippet or example and thank you in
advance

so i work on News and i put this class in select method for the cast
with element...
what are the impors and dependences to set for working with News in my
rcp.ui plugin?
where can i watch for something like this?

You can find examples of this e.g. in FeedItemViewUIAdvisor.

thanks for the hint, but i have another question:
i have observed that the new feed subscription are independent from
jazz server repository, differently to workitem feeds...
exists one way to fetch this NewsItem directly from client feedreader,
without passing from repository?

You can find examples of this e.g. in FeedItemViewUIAdvisor.
where can be found this examlpe?
is this in a wiki-page?

i'm a novice developer interested in feeds fetching & filtering.
in my rtc client i have created an additional view, that in my
intentions should contain only the news of user subscription
excluding the other artifact news...

can i do this in a ui plugin, without involving service, common and
client plugin?

thank in advance

Yes, the eclipse client is capable to download both repository feeds and
normal feeds. it will not call the repository if the feed is from
external. From your filter it should not make any difference if the feed
is from the repository or external.

now i have added and implemented my new filters, but if i try to add
more than three, only the first, second and third are visibles
because the space assigned to checkbox item filters not enough...

how can i modify this portion of user interface, maybe whit a show
all-hide details button?

any example?
thanks in advance
