gtk:window-default-icon-list ()

icons -- a list of gdk-pixbuf:pixbuf objects

The gtk:window-icon-list function returns the default icon list. The (setf gtk:window-icon-list) function sets an icon list to be used as fallback for windows that have not had the gtk:window-icon-list function called on them to set up a window specific icon list. This function allows you to set up the icon for all windows in your application at once.
