public abstract class AbstractDateTimeField

extends TextField

implements ReflectionSetter

The AbstractDateTimeField class is an abstract Component that can be used as the baisis for allowing a user to enter in a date or time.

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

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