Hi,

I would like to change my font on a label, but I do not want to use  
FontButton. How can I get the font information (I guess the  
Pango::FontDescription) of the font on my label, or for that matter font  
used with any widget where font is used?

Thank you in advance.

You should be able to to modify font used in most any widget with the  
Gtk::Widget#modify\_font(font), providing font is an instance of  
Pango::FontDescription. However currently (Ruby 1.8.6 and Ruby-GNOME2  
rel 2-0.17.0-rc1) this does not seem to be the case. I was only able to  
manipulate fonts on Gtk::Label objects and editable objects like  
Gtk::Entry. I could not change font on button text or button labels. I  
believe this will change in the future.
