Hi,
Yes, this seems like the job for a subclass. The problem here is the
ViewStack only measures the selectedChild.
So there is no possibility of knowing anything about the other children
until the child becomes the selected child.
On the other hand, if you know you have all of your content loaded in each
tab, I see no reason why you couldn't set creation policy to all. Listen to
creation complete and loop through all the children of the view stack doing
a;
semi code
var maxWidth:Number = 0;
var maxHeight:Number = 0;
var len:int = numChildren;
for (var i:int = 0; i < len; i++)
{
var child:IUIComponent = IUIComponent(getChildAt(i));
maxWidth = Math.max(child.getExplicitOrMeasuredWidth(), maxWidth);
maxHeight = Math.max(child.getExplicitOrMeasuredHeight(), maxHeight);
}
var window:Container = Container(parent);
var vm:EdgeMetrics = window.viewMetrics;
// this takes into account titlebar and borderMetrics of the TitleWindow
window.width = maxWidth + vm.left + vm.right;
window.height = maxHeight + vm.top + vm.bottom;
That needs to be in a TabNavigator subclass after you know for sure ALL
children have been created.
I don't know if that will work, but this is where I would start dealing with
the same problem.

You can find more by solving the problem then by 'asking the question'.
