[flexcoders] Re: HorizontalList itemRenderer size does not resize on refresh
@Thomas variableRowHeight=true in the mxml.
@Alex I tried remeasuring and resizing but this didn't work right off, so I
went with Amy's solution.
@Amy--that worked. It's always a pain to strip down to a repeater and work up
some list functionality but it gives you so much more control, as well as less
time-consuming mystery.
Thanks all! Matt Garland.

How do I force the HorizontalList to resize the renderers en masse after the

Re: [flexcoders] Re: HorizontalList itemRenderer size does not resize on refresh
Hi
show me the code how your vertical list set to variable height=true , i need
some thing of this sort to apply on a popupmenubutton to reduce the height and
width .please help me out.
thanks,
Tom.

I just noticed that when the largest answer randomly ends up in the first
position, the result is fine, so it's definitely a matter of getting the
horizontal list to act as if variableRowHeight is set to true, and not just
take the measurement of the first renderer and go with that.

HorizontalList does not have variableRowHeight, and its default behavior _is_ to just measure the first item and pretend all the other items are the same height. It sucks, but it seems to me no one is smart enough to calculate the optimal best height for the items, taking all possible scenarios into account, in a way that won't perform really slowly. Try using a Repeater instead. HTH; Amy
[flexcoders] Re: HorizontalList itemRenderer size does not resize on refresh
I had a similar predicament recently...
In my renderer code, I setup a listener to respond to external data changes.
In my case, I just needed to call invalidateDisplayList but you could reset
your sizes/etc. based upon the new data.
ReportHorizontalList(this.parent.parent).dataProvider.addEventListener(CollectionEvent.COLLECTION_CHANGE,
outsideCollectionChanged);
private function outsideCollectionChanged(evt:CollectionEvent):void{
invalidateDisplayList();
}

[flexcoders] Re: HorizontalList itemRenderer size does not resize on refresh
Thx. Gave it a whirl, no dice.
I need somehow to make the HorizontalList act like it had multiple image sizes,
and measure them to get the largest rather than going with the first.

RE: [flexcoders] Re: HorizontalList itemRenderer size does not resize on refresh
You might have to call measureWidthOfItems/measureHeightOfItems and set
columnWidth and rowHeight.
