Using Font.Style.FromInt(0) for scope title

[FanMSL]

I would like to configure Font.Style to be bold how can I do this
I try to use Font.Style.FromInt(1) but all four item bold etc... stay false

How can I configure a Font.Style ? to my needs, any help or a manual explain this function argument, I did try wiki already no help reference found

Thanks in advance

I am to configure style bold understrike etc or none, only after set title and next reconfigure by style property by using fromint.

scope1.Title=set Title...
scope1.Title.Font.Style.FromInt(1);

Why is style not working when configure the style by fromint function when create the set Title... object?
