[FLEX] [AS3] Change ActionBar Title label size using Actionscript

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!!!
