[flexcoders] spark Panel titleBar equivalent

[bhaq1972]

In flex 3
I used do add buttons to MyPanel (extends mx.containers.Panel) titleBar.

var button:Button = new Button();
this.titleBar.addChild(button);


whats the equivalent to this in Spark?

one way i'm thinking of is using a basic layout, and positioning the buttons 
where I want. 

Just wanted to get an idea what approach others would take.

thanks
