TFlxFont.Scheme Property
Font scheme. This only applies to Excel 2007. Note that this property takes over other properties like font name: If the scheme is for example "Major" and the theme has a Major font defined as calibri, then the font will be Calibri no matter if you change the font name.
To manually change the font name, make sure to set Scheme = TFontScheme.None
