How-to build a font sub-menu?

[Simon Brown]

Not sure how to do this when using Rev 2.

I've used the Menu Builder to create the menu bar, and have created a 
Type-->Font menu item. But I am unsure of how to get the list of 
typefaces returned by fontNames() into the Font sub-menu.

Can anyone help with this, or point to a stack that shows how to do 
this?

Thanks,

Simon.
