-/**
- * @short A TQValidator to (dis)allow certain strings
- *
- * This validator allows you to accept only certain or to accept all
- * but certain strings.
- *
- * When used in rejecting mode, accepts only strings not in the
- * stringlist. This mode is the default and comes in handy when asking
- * the user for a name of some listed entity. Set the list of already
- * used names to prevent the user from entering duplicate names.
- *
- * When used in non-rejecting mode, accepts only strings that appear
- * in the stringlist. Use with care! From a user's point of view this
- * mode is hard to grasp.
- *
- * This validator can also fix strings. In rejecting mode, a number
- * will be appended to the string until it is Acceptable. E.g. if
- * "foo" and "foo 1" are in the stringlist, then fixup will change
- * "foo" to "foo 2", provided "foo 2" isn't in the list of forbidden
- * strings.
- *
- * In accepting mode, when the input starts with an Acceptable
- * substring, truncates to the longest Acceptable string. When the
- * input is the start of an Acceptable string, completes to the
- * shortest Acceptable string.
- *
- * NOTE: fixup isn't yet implemented.
