| * |
| * #GIcon is a very minimal interface for icons. It provides functions |
| * for checking the equality of two icons and hashing of icons. |
| * |
| * #GIcon does not provide the actual pixmap for the icon as this is out |
| * of GIO's scope, however implementations of #GIcon may contain the name |
| * of an icon (see #GThemedIcon), or the path to an icon (see #GLoadableIcon). |
| * |
| * To obtain a hash of a #GIcon, see g_icon_hash(). |
| * |
| * To check if two #GIcons are equal, see g_icon_equal(). |
