<a class="link" href="class-gioicon.html" title="gio.Icon"><code class="classname">gio.Icon</code></a>
is a very minimal interface for icons. It provides functions for checking
the equality of two icons, hashing of icons and serializing an icon to and from strings.
</p><p>
<a class="link" href="class-gioicon.html" title="gio.Icon"><code class="classname">gio.Icon</code></a>
does not provide the actual pixmap for the icon as this is out of GIO's
scope, however implementations of
<a class="link" href="class-gioicon.html" title="gio.Icon"><code class="classname">gio.Icon</code></a>
may contain the name of an icon (see
<a class="link" href="class-giothemedicon.html" title="gio.ThemedIcon"><code class="classname">gio.ThemedIcon</code></a>),
or the path to an icon (see
<a class="link" href="class-gioloadableicon.html" title="gio.LoadableIcon"><code class="classname">gio.LoadableIcon</code></a>).
</p><p>
To check if two GIcons are equal, see
<code class="methodname"><a class="link" href="class-gioicon.html#method-gioicon--equal" title="gio.Icon.equal">gio.Icon.equal</a></code>().
</p><p>
For serializing a <a class="link" href="class-gioicon.html" title="gio.Icon"><code class="classname">gio.Icon</code></a>,
use <code class="methodname"><PYGTKDOCLINK HREF="method-gioicon-%20-to-string">gio.Icon.to_string</PYGTKDOCLINK></code>() and
<code class="methodname"><PYGTKDOCLINK HREF="method-gioicon-%20-new-from-string">gio.Icon.new_from_string</PYGTKDOCLINK></code>().
</p><p>
If your application or library provides one or more
<a class="link" href="class-gioicon.html" title="gio.Icon"><code class="classname">gio.Icon</code></a>
implementations you need to ensure that each GType is registered
with the type system prior to calling
<code class="methodname"><PYGTKDOCLINK HREF="function-gioicon--new-from-string">gio.icon_new_from_string</PYGTKDOCLINK></code>().

The <code class="methodname">equal</code>() method checks if two icons are equal.
</p></div><div class="refsect2" title="gio.Icon.to_string"><a name="method-gioicon--to-string"></a><h3>gio.Icon.to_string</h3><pre class="programlisting"><code class="methodsynopsis"> def <span class="methodname">to_string</span>(<span class="methodparam"></span>)</code></pre><table border="0" width="100%" bgcolor="#FFECCE"><col align="left" valign="top" width="0*"><tbody><tr><td><p><span class="term"><span class="emphasis"><em>Returns</em></span> :</span></p></td><td>An UTF8 string or <code class="literal">None</code>

</td></tr></tbody></table><p>
The <code class="methodname">to_string</code>() method 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
<code class="methodname"><a class="link" href="class-gioicon.html#function-gio--icon-new-from-string" title="gio.icon_new_from_string">gio.icon_new_from_string</a></code>()
to get icon back from the returned string.
</p><p>
The encoding of the returned string is proprietary to GIcon except in the following two cases
</p><p>
If icon is a <a class="link" href="class-giofileicon.html" title="gio.FileIcon"><code class="classname">gio.FileIcon</code></a>,
the returned string is a native path (such as /path/to/my icon.png) without escaping
if the <a class="link" href="class-giofile.html" title="gio.File"><code class="classname">gio.File</code></a>
for icon is a native file. If the file is not native, the returned string is the result of
<code class="methodname"><a class="link" href="class-giofile.html#method-giofile--get-uri" title="gio.File.get_uri">gio.File.get_uri</a></code>()
(such as sftp://path/to/my%20icon.png).
</p><p>
If icon is a <a class="link" href="class-giothemedicon.html" title="gio.ThemedIcon"><code class="classname">gio.ThemedIcon</code></a>
with exactly one name, the encoding is simply the name (such as network-server).
