public class DateSelector

extends java.lang.Object

DateSelector is a utility class to handle the creation of a set of date popup menus. The code is broken into a set of static methods for quick and easy access to the individual select objects:

  ElementContainer ec dateSelect = new ElementContainer();
  String myName = "mydate";
  ec.addElement(DateSelector.getMonthSelector(myName));
  ec.addElement(DateSelector.getDaySelector(myName));
  ec.addElement(DateSelector.getYearSelector(myName));
  

There are also methods which will use attributes to build a complete month,day,year selector:

  DateSelector ds = new DateSelector(myName);
  dateSelect = ds.ecsOutput();
  

The above element container would use the onChange setting and may hide the selected day if set via showDays().
