Hi there,

I'm using Flash Builder 4.7 / Flex to build a Mobile Tabbed App.

How do I change the font size of the title label in the ActionBar for a Mobile TabbedViewNavigatorApplication?

I know how to do it in CSS / with Styles:
Code:
	
<fx:Style>
		@namespace s "library://ns.adobe.com/flex/spark";

		s|ActionBar #titleDisplay
		{
			fontSize:20;
		}
	
	</fx:Style>
However how do I do it in Actionscript?

I can change the title of the ActionBar label using actionscript like so:
Code:
navigator.actionBar.title="New Title"
But can't figure out how to change the fontSize in Actionscript!!! Please help!

I've tried
Code:
setStyle("fontSize",20)
but can't find anything to append it to that works!!!
