Changing bgColor dynamically?

Question

Is it possible to use a repeater, with the dataProvider, to
change backgroundColor dynamically?
for instance:
<mx:Repeater ........ >
<mx:Canvas
backgroundColor="{repeaterIdHere.currentItem.bg_color}"
width="100%" height="100%" />
</mx:Repeater>

Answer 1

The Repeater will create a series of instances of the
contents between <mx:Repeater> and </mx:Repeater>. For
example, if you wanted 6 Canvases each with a different background
color, the Repeater would work:
[Bindable] private var dp:ArrayCollection = new
ArrayCollection(
[{color:0xff0000},{color:0xff8800},{color:0xffff00}, ... ]);
<mx:Repeater id="rep" dataProvider="{dp}" >
<mx:Canvas backgroundColor="{rep.currentItem.color}" ...
>
</mx:Canvas>
</mx:Repeater>
