Fontfamily

[Bernd Demian <Bernd Demian csc-dd de>]

Hallo,
After select a font with gtk_font_selection_dialog I must now, if the
font is monospace. 
   PangoFontDescription *desc =
      pango_font_description_from_string(font_string);
   const gchar *familie = pango_font_description_get_family(desc);
   if(!pango_font_family_is_monospace(??????))
....
But I can't get no the PangoFontFamily, has anybody a idea to get the
family object?
Thanks Bernd
