Description

XfceIconTheme is used to look up themed icons. It is actually a singleton object, so successive calls to xfce_icon_theme_get_for_screen() 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. XfceIconTheme 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.
