Hi, i'm trying to create a slideshow with an rss feed from
flickr. i am using a datagrid component to store the images
(because of the transitioning effects when i add or delete an item
from its dataProvider. I can go through the images very effectively
by simply removing the first item in the array collection, but then
i get to the end and of course the slideshow doesn't look because
i've removed all the items. is there an easy way for me to simply
take the first object in the array collection and move it to the
end? i've tried photoFeed.setItemAt(object, int); but i don;t know
how to call on the first object of the array collection. also, for
the int variable i try to use photoFeed.length because i want to it
move to the end of the array which the length should be the correct
number since the array's indexing start at 0.
Though I am unable to understand the requirement of moving an
item to the end for a slide show, you can use
var item:Object = photoFeed.removeItemAt(0);
to achive what you want.
If you simply want to traverse the images one by one till the
end you just need to use the createCursor API and obtain a cursor.
By calling moveNext on the cursor you navigate through the
collection till moveNext returns false.
thanks for the reply, i'll try your suggestion about the
createCursor, but it sounds like the collection won't continue once
it gets to the end? i'm trying to create an endless slideshow. but
thanks again for the help!
