Custom Font Chooser

I am wanting to implement my own custom inline font chooser in a text 
application I am writing, but am not sure how I should be hooking up 
to NSFontManager.  I know that I should setSelectionFont:isMultiple: 
on the font manager when the text changes within my text controls, but 
I don't know how my custom font UI is supposed to pick up on these 
changes.  It appears that NSFontManager speaks directly to the font 
panel and menu without sending any notification or anything.  Is this 
the case?  Or is there a way to be notified when the selection font 
has changed?

Thanks,

Francisco
