Itemrenderer for icone on Titlebar

[Hugo Ferreira]

How to add an icone to TitleBarModel, or even better, how to apply an
itemrenderer:

<js:Container id="panel1" width="100%">
<js:beads>
<js:TitleBarModel title="Panel 1" />
<js:VerticalLayout />
</js:beads>
<js:Label text="Top Line 1" className="menuItem" />
<js:Label text="Middle Line 1" className="menuItem" />
<js:Label text="Last Line 1" className="menuItem" />
</js:Container>

The goal is to build my own menu based on Accordion.
