[Gtk-sharp-list] chaning FONT of Gtk.RadioButton

[True Friend]

Hi
I am trying to change font of gtk.radiobutton as follows
this.radiobutton3.ModifyFont(Pango.FontDescription.FromString("Urdu_Emad_Nastaliq
14"));
But it DOES NOT change. Same is working for gtk.label, gtk.entry,
gtk.textview. I am putting this code in MainWindows Constructor under
Build();
Any ideas to do this thing? I've tired to change the label text of same
radiobutton which works but not the FONT :(
Regards
