Gtk.IconTheme.prototype.lookup_icon

function lookup_icon(icon_name:String, size:Number, flags:Gtk.IconLookupFlags):Gtk.IconInfo {
    // Gjs wrapper for gtk_icon_theme_lookup_icon()
}

Looks up a named icon and returns a structure containing information such as the filename of the icon. The icon can then be rendered into a pixbuf using Gtk.IconInfo.prototype.load_icon. (Gtk.IconTheme.prototype.load_icon combines these two steps if all you need is the pixbuf.)
