The gtk.FontSelectionDialog 
is a dialog box containing a gtk.FontSelection 
widget that the user can use to select a font according to the desired
family, style and size.
The set_font_name() 
method sets the initial font selection. The current font selection is
retrieved using the get_font_name() 
method. The font selection dialog has a preview area that contains a gtk.Entry that
displays text using the currently selected font. The preview text can be
retrieved with the get_preview_text() 
method and set with the set_preview_text() 
method.
Filters can be used to limit the font selections. There are 2
filters in the gtk.FontSelectionDialog 
- a base filter and a user filter. The base filter cannot be changed by the
user, so this can be used when the user must choose from the restricted set
of fonts (e.g. for a terminal-type application you may want to force the
user to select a fixed-width font). The user filter can be changed or reset
by the user, by using the  button or
changing the options on the Filter page of the
widget.
In GTK+ 2.2 and above the gtk.FontSelectionDialog
does not have filters, a  button or a
Filter page.

current font using the value of fontname. The method
returns True if the font exists and could be
selected.
