Restricting the fonts in NSFontPanel

I can't figure this one out!

The developer docs say that
- (BOOL)fontManager:(id)sender willIncludeFont:(NSString *)fontName
is no longer called on the font manager (or panel) delegate but there 
is no suggested alternative for controlling the presented fonts.

I can't find any way to go about restricting the fonts to fixed-pitch 
only.

Any help appreciated,
