This is a very minimal interface for icons.
It provides functions for checking the equality of two icons and hashing of icons. Glib::Icon does not provide the actual pixmap for the icon as this is out of GIO's scope. However implementations of Icon may contain the name of an icon (see ThemedIcon), or the path to an icon (see LoadableIcon).
To obtain a hash of an Icon instance, see hash().
To check if two Icon instances are equal, see equal().

Generates a textual representation of icon that can be used for serialization such as when passing icon to a different process or saving it to persistent storage.
Use g_icon_new_for_string() to get icon back from the returned string.
The encoding of the returned string is proprietary to Icon except in the following two cases
<itemizedlist> <listitem>
If icon is a FileIcon, the returned string is a native path (such as <literal>/path/to/my icon.png</literal>) without escaping if the File for icon is a native file. If the file is not native, the returned string is the result of g_file_get_uri() (such as <literal>sftp://path/to/my%20icon.png</literal>).
</listitem> <listitem>
If icon is a ThemedIcon with exactly one name, the encoding is simply the name (such as <literal>network-server</literal>).
