public class DateField

extends AbstractDateTimeField

The DateField class is a TextField component that can be used to allow a user to enter in a date.

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

The DateField also contains a DatePicker object that can be popped down by the user. This allows the user to navigate to a valid date 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.

public DatePicker getDatePicker()

echopoint.DatePicker

setDatePicker

public void setDatePicker(DatePicker newDatePicker)

Sets the a new DatePicker into the DateField. Be warned that the DateField class replaces the CalendarSelectionModel of the DatePicker with its own version. It does this because it is interested in only some of the update events.

The implication of all this is that CalendarSelectionModel model listeners should be added after the DatePicker has been set into the DateField. /

Parameters:

newDatePicker - echopoint.DatePicker

setText

public void setText(java.lang.String newValue)

Sets the text contained in the document model. If this text component's document model is null, throws a NullPointerException.

                     throws java.lang.Exception

Description copied from interface: ReflectionSetter

Called to save the old value of a field, set in a new value and return the old value of a field. This interface allows a field set operation to be "delegated" back into the class that has permission to perform the field set.

 public Object set(Field f, Object newValue) throws Exception {
      Object oldValue = f.get(this);
      f.set(this,newValue);
      return oldValue;
