Checks whether or not this has an icon name.
get_icon_name will always return some value, even if this has no icon name set; has_icon_name can be used to tell if that icon name is real or not.
(Note that if has_icon_name returns false, but has_name returns true, then the name returned by get_icon_name is this<!-- -->'s name. Only when both methods return false does get_icon_name return a generic fallback name.)

true if get_icon_name returns this<!-- -->'s icon name, false if it returns a fallback name. |
