| 34 | /** | |
| 35 | * DateSelector is a utility class to handle the creation of a set of | |
| 36 | * date popup menus. The code is broken into a set of static methods | |
| 37 | * for quick and easy access to the individual select objects: | |
| 38 | * | |
| 39 | * <pre> | |
| 40 | * ElementContainer ec dateSelect = new ElementContainer(); | |
| 41 | * String myName = "mydate"; | |
| 42 | * ec.addElement(DateSelector.getMonthSelector(myName)); | |
| 43 | * ec.addElement(DateSelector.getDaySelector(myName)); | |
| 44 | * ec.addElement(DateSelector.getYearSelector(myName)); | |
| 45 | * </pre> | |
| 46 | * | |
| 47 | * There are also methods which will use attributes to build a | |
| 48 | * complete month,day,year selector: | |
| 49 | * | |
| 50 | * <pre> | |
| 51 | * DateSelector ds = new DateSelector(myName); | |
| 52 | * dateSelect = ds.ecsOutput(); | |
| 53 | * </pre> | |
| 54 | * | |
| 55 | * The above element container would use the onChange setting and may | |
| 56 | * hide the selected day if set via showDays().<br> | |
