You can use an iframe hovered over the app (some have built components around embedding this in Flex) to display the HTML directly, or you can automatically regenerate the screenshots server-side at some interval (nightly, hourly, every minute--depending on what you need).
Hmm. That sounds interesting but I'd struggle to do it code wise as I've never done that. Are there any examples you know of that show this being done?
Also I'm just checking out Iframe for the first time and it seems to be more of a way to embed website pages allowing you to make use of them within a flex app. All I want is live images of the site which once clicked will open up that particular site in an new instance of internet explorer if that makes sense.
Could this be achieved with IFrame?

For that kind of thing, you may want to stick with just images in
Flex, and make sure they're up-to-date by polling the web sites
server-side and re-generating the images. I think it could be achieved
with iframe and clickable transparent overlays, but scaling down the
pages (especially images) could be tricky. You'll need to find a way
to script a browser to generate screenshots on the server, which will
also be tricky, but considerably less so. The other alternative is to
parse the HTML and build thumbnails yourself in Flex, but that's just
I see what you mean about the clickable transparent overlays as this would stop the user interacting with the images which is what I want and I also see what you mean about it being hard to scale the images as it seems iframe has it's own scrollbars and includes the entire screen rather than thumbnails.
My further problem is that I need to display these images in a tilelist that the user can scoll up and down and the images need to be drag and droppable between 2 tilelists. Yikes. They already are drag and droppable at the moment and are all displayed within a tilelist but I just need to make them live.
Now I'm scared. Ha.
Yeah, it won't be trivial, unfortunately. If I were you, I'd
investigate the server-side automated screenshot-refresh solution. On
Linux servers, you should be able to do something with imagemagick and
shell scripts, provided X is available. On a Windows system, you may
be able to do something through OLE automation of IE...
Yep I was hoping for a trivial solution to be honest.
I didn't want to use any server side solutions as it's basically a desktop app which I wanted to be completely stand alone plus I'm very inexperienced at using flex with server side code etc.
I'll look further into iframe though and see what I can come up with. Thanks for your help though.
Ah, with a desktop app (AIR--if a straight Flash desktop app, this
does not apply), you should be able to use the HTML component, shrink
it with scaleX and scaleY, put an overlay on that for clicking, and
that should be enough. If you want to get fancy, you could then
capture that image (see, e.g., what AlivePDF does), cache it, and
re-use it until you decide it's out of date, so you don't need to
re-render all the pages.
Sorry, when people ask Flex questions, I typically assume
browser-based unless explicitly stated otherwise. I think others do
Excellent mate. I'm sure that'd work to get the images in. My fault for not mentioning that it was a desktop air app.
The only tricky part will be putting them in a tilelist but I'll experiment and see what I can come up with and will post a new topic if I have problems.
Thanks a lot. All the best.
