Fonts in GTK+ 1.2

["Paulo R. Panhoto" <panhoto terra com br>]

   Hi,

   This is my first post to this list. I've just started with GTK+ 
programming. I have a doubt about changing fonts with GTK 1.2. How can I 
change the font of a single widget without affecting the font of the 
whole window?? I guess my approach wasn't correct in this sense because 
I changed the font using gtk_widget_set_style(). Does anyone have an 
idea on how can I do that?

   Thanks in advance,

   Paulo
