Thanks for mentioning that Tracey! I just realized it some minutes ago. Is there no way to tell the TileList to not remove children that are not visible?
I've used a MXML component as the itemRenderer but want to rewrite it in ActionScript. It has a Label and an Image component in it. I've set a dataProvider with a label and icon field in it in the TileList. How can I access the label and icon data (used for the Image's source) in the itemRenderer? In createChildren() the data.icon/data.label are not yet available so I always accessed them in an init() method that was called on creationComplete. But I guess this is not the way to go since everytime I scrolled the TileList it had a high impact on the item redrawing, giving me a short delay before the items actually reappear. So where is a good place/time to access the data property? Thanks for the help so far!

Remember that the visual elements in a list only exist when they are visible. Any setting af the visual state of an itemRenderer must be driven by data in the dataProvider, and invoked in the set data() or updateDisplayList functions(). You cannot successfully address a visual element from the "outside" Tracy _____ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Sascha Sent: Thursday, January 04, 2007 8:37 AM To: [email protected] Subject: RE: [flexcoders] Removing the item gap in a TileList? Thanks Paromita but when I set the rowHeight property of the TileList it just crops my thumbnails and the 4px gap is still there. Also I'm wondering how can I set properties in the itemRenderer instance while it is somehow instanciated internally by the TileList? Let's say I've made a custom itemRenderer named TileListerItem, and then I associate it in the TileList: itemRenderer = new ClassFactory(TileListerItem); . and I'm using an Image component in the itemRenderer and want to set the width and height of it at a later point, how do I access these properties without having a tangible instance? Would be cool if somebody can give me a hint there! In any way, thanks a lot!

I don't know if this would solve your problem but you can adjust the vertical gap between the items of a tilelist by adjusting the rowHeight property value. Set appropriate value for rowHeight in yout tilelist. Regards, Paromita Sascha <[EMAIL PROTECTED]> wrote: Hi list, I'm using a TileList component which is populated with thumbnail items. I've wrote a custom itemRenderer for it that uses a HBox as the base. I want there to be no gap between the thumbnails at all. Horizontally I can get rid of any spacing by setting horizontal gap to 0 however this does not seem to work with vertical gap. No matter what I'm trying I always get a vertical gap of ~4 pixels. The items that are put in the TileList are small thumbnails where the image fills out the whole area of an item. I've tried other containers like Canvas and Image for the itemRenderer too but without success. Let's say my thumbnails are 32x32 pixels. I'm setting both h and v gap and all padding of the HBox to 0, even set the rowHeight of the TileList to 32 but the vertical gap will appear and it seems the thumbnails are cropped. Can somebody tell me how to get rid of the vertical spacing? Any other simple container would be ok as the itemRenderer too. Thanks for any help!
