Finally got it to work, thought I would offer the code to anybody who
wants this in Flex 2.
I changed it a little bit, I made a custom component that extends Box
(called FBox... F for Flow). Anyway, not sure how flexible it is, but
it should be a good start for somebody looking to do something like this.
package com.myComponents.ui
{
import mx.containers.Box;
import mx.core.EdgeMetrics;
import mx.core.UIComponent;
public class FBox extends Box
{
public function FBox()
{
super();
}
override protected function
updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void
{
super.updateDisplayList(unscaledWidth, unscaledHeight);
var vm:EdgeMetrics = viewMetricsAndPadding;
var lastX:Number = vm.left;
var lastY:Number = vm.top;
var rowHeight:Number = 0;
for (var i:Number = 0; i < numChildren; i++)
{
var child:Object = getChildAt(i);
if (lastX + child.width > unscaledWidth -
vm.right)
{
lastX = vm.left;
lastY += rowHeight;
}
child.move(lastX, lastY);
lastX += child.width;
rowHeight = Math.max(rowHeight, child.height);
}
}
}
}
