'GI.Gtk.Interfaces.FontChooser.FontChooser' is an interface that can be implemented by widgets
displaying the list of fonts. In GTK+, the main objects
that implement this interface are 'GI.Gtk.Objects.FontChooserWidget.FontChooserWidget',
'GI.Gtk.Objects.FontChooserDialog.FontChooserDialog' and 'GI.Gtk.Objects.FontButton.FontButton'. The GtkFontChooser interface
has been introducted in GTK+ 3.2.
