public class TimeField

extends AbstractDateTimeField

The TimeField class is a TextField component that can be used to allow a user to enter in a time value.

The TimeField has a DateFormat that is used to parse and sets its current value (remember it is derived from TextField).

The TimeField also contains a list if time values that can be popped down by the user. This allows the user to navigate to a valid time without having to enter it in the right format.

Remember that at any one time the text value can be an invalid date. You must check the date in you code before accepting it as valid.
