JCalendar is a Java date chooser bean for graphically picking a
date. JCalendar is composed of several other Java beans, a
JDayChooser, a JMonthChooser and a JYearChooser. All these beans
have a locale property, provide several icons (Color 16x16, Color
32x32, Mono 16x16 and Mono 32x32) and their own locale property
editor. So they can easily be used in GUI builders. Also part of the
package is a JDateChooser, a bean composed of an IDateEditor (for
direct date editing) and a button for opening a JCalendar for
selecting the date.
The newest version!
