public enum IconSize
Built-in icon sizes.
Icon sizes default to being inherited. Where they cannot be inherited, text size is the default.
All widgets which use `GtkIconSize` set the normal-icons or large-icons style classes correspondingly, and let themes determine the actual size to be used with the `-gtk-icon-size` CSS property.
