How to obtain font info

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.
