- * @Short_description: A GIcon that allows numbered emblems
- *
- * GtkNumerableIcon is a subclass of #GEmblemedIcon that can
- * show a number or short string as an emblem. The number can
- * be overlayed on top of another emblem, if desired.
- *
- * It supports theming by taking font and color information
- * from a provided #GtkStyleContext; see
- * gtk_numerable_icon_set_style_context().
