How can I avoid hard coding this width?

Question

I have something like this:
<s:SkinnableDataContainer
                              width="200"
                              itemRenderer="MyItemRenderer"
                              dataProvider="{ dp }">
If I have 4 items each 50px wide, I would set the width to 200px.
However, I want to avoid hardcoding the width.
How can I extract the width from the item renderer?

Answer 1

You might want to try not setting a width and setting requestedColumnCount on the layout instead.
<s:List>
    <s:layout>
        <s:HorizontalLayout requestedColumnCount="2" />
    </s:layout>
    <s:dataProvider>
        <s:ArrayList>
            <fx:String>0000</fx:String>
            <fx:String>1000</fx:String>
            <fx:String>2000</fx:String>
            <fx:String>3000</fx:String>
        </s:ArrayList>
    </s:dataProvider>
</s:List>
