[Flashr] tag search results in slideshow

[gloria kao]

Hi, Doug:

Yes, that's exaclty what I look for. Thanks a lot.
I took a quick look on the codes, and ...

 1. Where is the MovieClip myTarget (I supposed this is the display area)?
Did you put it on the stage or not? How could I access this? Because I'd
like to do something like...click on it to duplicate the image.

2. You do request all 500 photos at once, but you are smart to only save the
imageURL and photoPageURL in slideList[]. p.s: Here I have another
question- does Flash come with a linking list data structure? Is the
"Array" here equal to the normal array in data structure? Becuase I see you
use slideList.push(), or maybe it works like a stack?

3. Wows! I did not realize that it takes some much actionscript coding to do
the slideshow presenation for non embedded images. Could you basically say a
few words about the basic discipline behind? I saw lots of event dispatch
stuff. For example, slideLoader.addEventListener('slideLoaded', this);
When would you explect the listener receive the event slideLoaded to invoke
the callback function slideLoaded? I just don't get it. I already read some
sections from the Flash help. It seems that you use addEventListener() to
"wait for" some event happens, so that you can proceed with the callback
funciton, but who send the event, and where (so that you can control the
sequence of function, and maybe the latency in-between)?

Thanks very much!

Gloria
