* @class_path: (allow-none): the class path to use when looking up the style,

* @type: a type that will be used along with parent types of this type
* when matching against class styles, or #G_TYPE_NONE
*
* Creates up a #GtkStyle from styles defined in a RC file by providing
* the raw components used in matching. This function may be useful
* when creating pseudo-widgets that should be themed like widgets but
* don't actually have corresponding GTK+ widgets. An example of this
* would be items inside a GNOME canvas widget.
*
* The action of gtk_rc_get_style() is similar to:
* |[
* gtk_widget_path (widget, NULL, &path, NULL);
* gtk_widget_class_path (widget, NULL, &class_path, NULL);
* gtk_rc_get_style_by_paths (gtk_widget_get_settings (widget),
* path, class_path,
* G_OBJECT_TYPE (widget));
* ]|
*
* Return value: (transfer none): A style created by matching with the
* supplied paths, or %NULL if nothing matching was specified and the
* default style should be used. The returned value is owned by GTK+
* as part of an internal cache, so you must call g_object_ref() on
* the returned value if you want to keep a reference to it.
