["alan" <alan ielinux com>]

Dear sir,

How to set over two kind different fonts and font size in program?

I can set it in gtkrc file like this...

 

style "gtk-default-zh-tw" {
 fontset = "-adobe-helvetica-medium-r-normal--18-*-*-*-*-*-iso8859-1,\

    -adobe-helvetica-medium-r-normal--24-*-*-*-*-*-iso8859-1,\
    -*-*-medium-r-normal--18-*-*-*-*-*-big5-0,\
    -*-*-medium-r-normal--24-*-*-*-*-*-big5-0,*-r-*"
}
class "GtkWidget" style "gtk-default-zh-tw"

But if I have a widget with helvetica(in english font) and big5(in taipei font) fonts.

How to select and set different font size in widget??

Please help me! thanks. (from alan ielinux com)
