I haven't done this, so I'm just throwing out possibilities. Could you not create a custom component that acts as an item renderer for the list, wherein the custom component has two view states (normal and zoomed-in)? The only thing is, since this would operate inline to the list, I'm not sure what it does looks-wise to the overall list structure. On the other hand, if the zoomed-in window covers the list, I'm not sure you would care because once the zoomed in view returns to normal view state, the containing list should return to looking normal.
Another possibility is to pop the list item out such as you would do in a drag operation. In other words, convert the list item through the BitMapData class to an image and have it move to the center of the screen at which point you could drop it automatically into your borderless pop-up. At that point, you can populate the pop-up with the expanded list item info. Not sure if either of those ideas work for you. R. Grimes
