<p>
<a class="link" href="XfceIconTheme.html" title="XfceIconTheme"><span class="type">XfceIconTheme</span></a> is used to look up themed icons. It is actually a singleton
object, so successive calls to <a class="link" href="XfceIconTheme.html#xfce-icon-theme-get-for-screen" title="xfce_icon_theme_get_for_screen ()"><code class="function">xfce_icon_theme_get_for_screen()</code></a> will use any
previously-generated icon data, if available. There are three ways of finding
icons: with a simple name, with a list of names, or with a predefined
category. Custom categories can also be registered. <a class="link" href="XfceIconTheme.html" title="XfceIconTheme"><span class="type">XfceIconTheme</span></a> uses
the XDG basedir spec when determining directories in the icon search path. If
you need to change these directories for any reason, an API is provided for
that.
