gtk:settings-gtk-sound-theme-name (object)

object -- a gtk:settings object
setting -- a string for the sound theme name

The accessor for the gtk-sound-theme-name slot of the gtk:settings class gets or sets the XDG sound theme to use for event sounds. See the Sound Theme specification for more information on event sounds and sound themes. GTK itself does not support event sounds, you have to use a loadable module like the one that comes with the libcanberra library.
