...but is not as straightforward as most other extensions.
Since the creator's website seems unavailable now for this product I will summarize what I found out so that others don't spend few hours making it work.
Thanks to other posters for clarifying that:
-the component does not appear to do much
-the feed (and I am talking about the rss/url to the feed) has to be previously defined in the basic feeder (I am using the original com_newsfeeds loaded with joomla). When you define a feed in com_newsfeeds you give it a name and put it in a category, and these names and categories are what you will use in nf_scroller_XT
I loaded both the component and the module, both version 1.3.5, not sure that the component is needed and like others said, does not point to anything we can understand (must be doing something under the covers...)
-setting it up was, for me, trial and error
-the module configuration:
--model class suffix: leave it empty, this is too much for me and I didn't need it
--source: I could not make it work for "all" but this wasn't my intent, you can also choose "cat" (for category) or "single", I chose "single"
--category names: I left empty as i chose "single"
--single feed name: I wrote the name of the feed exactly (copy and paste) as I have it named in com_newsfeeds
--the rest gives you the option to show different parts of the news feed but BY DEFAULT THEY ARE ALL OFF, set one on at a time to figure out what they do, normally you would want to show at least the feed title.
--the bars are only to separate the feed display
--another trick: break chars BY DEFAULT (I think) SOME OF THEM ARE ON but the character field to use is empty, when this is empty it would use the default character. The problem is that BY DEFAULT the DEFAULT CHARACTER IS EMPTY TOO. You can set the default character towards the bottom (the third field from the bottom up)
--I did not experiment with the linkable option since I am not planning to use it
--direction: up/down, left/right
--align: the text inside the feed (any will do)
--behavior: if you chose up or down in the direction, choose scroll here, if left or right, choose slide.
--height: simple: how high will the module be
--wight: same
--scrollamount and srolldelay: I don't have them figure out yet but together seem to only set the speed (of scroll or slide)
--marquee options: I left empty
-- I didn't touch the rest (except that I wrote a default character to be safe, but since I chose to scroll I don't use any characters
Thumbs up to the apps features, the usability is tricky (for a newby like me) documentation unavailable.
I recommed it anyway... totally worth the setup time
