Hi List, quick question:
I am trying to iterate through a spark List component's itemRenderers / list items and would like to call a function in the ItemRenderers. How would i approach this? basically i need to reset a list and remove all active items.... ( and run a clean up function in each list item )... more info (in case you have time): I am using the s:list component for a thumbnail gallery (air app) and am not too sure about my approach to using itemRenders for this. I dynamically generate the thumbnails from larger images - if i do this every time there is a 'dataChange' event - then the list constantly rebuild the images ( i guess the spark list component uses a pool of list items ). The ItemRenderer's thumbnail bitmap is dynamically resized and resampled from a larger JPG. This is then assigned to a 'mx:Image' component. When re-assigning new Data - i would like to clean / clear all bitmaps in the list - to keep a low memory footprint. Hense why i am trying to iterate through the items in the list to clean / clear the bitmaps. is this the best approach? If you've made it this far, and feel somewhat inclined to help, here is the code i am using for my item renderer: http://kurst.co.uk/transfer/ListItemRenderer.txt Many thanks.... - Karim
