public class jcalendar

extends javax.swing.JComponent

implements java.awt.event.ActionListener

bDateChooser is a simple Date choosing component with similar functionality to JFileChooser and JColorChooser. It can be used as a component, to be inserted into a client layout, or can display it's own Dialog through use of the showDialog method.

bDateChooser can be initialized to the current date using the no argument constructor, or initialized to a predefined date by passing an instance of Calendar to the constructor.

Using the bDateChooser dialog works in a similar manner to JFileChooser or JColorChooser. The showDialog method returns an int that equates to the public variables ACCEPT_OPTION, CANCEL_OPTION or ERROR_OPTION.

bDateChooser chooser = new bDateChooser();
if (chooser.showDialog(this, "Select a date...") == bDateChooser.ACCEPT_OPTION) {
Calendar selectedDate = chooser.getSelectedDate();
// process date here...
}

To use bDateChooser as a component within a GUI, users should subclass bDateChooser and override the acceptSelection and cancelSelection methods to process the corresponding user selection.

The current date can be retrieved by calling getSelectedDate method.
