INTRODUCTION

This is a fork of the JCalendar project:

Luis Miranda:

• uses Maven 2
• supports TimeZones

Tom Sanders

• Various new features and bug fixes - see below

USAGE

Luis Miranda

• The JDateChooser class has a new method called setDateFormatCalendar. The underlying implementation will use the TimeZone of the selected calendar when displaying the date and time.

Components

• The dateVerifier property As well as the existing min/maxSelectableDate properties, the DateVerifier interface allows clients to specify arbitrary validation checks, for example valid business days. When present on JDayChooser, JCalendar or JDateChooser the DateVerifier.valid() method is called. For JDayChooser and JCalendar (and within JDateChooser obviously) the calendar buttons are disabled for dates that are not valid. If a JDateChooser has a spinner editor then invalid dates are skipped in the direction of travel. The same is true for values entered as text.

• The nullText property Sometimes it is nice to display some text in JDateChooser, rather than blank, when the date is null. For example null might mean "Open Ended" or whatever.

• The selectOnFocus property When a JDateChooser (that is the underlying JTextComponent) gains the focus, optionally select its text. Useful for keyboard junkies.

• Using a mnemonic is limited in that it does not require the component to have the focus. If there is more than one JDateChooser in your window Alt+C will only ever apply to the one most recently created. Changed to use the input/action map.

  When focused in the underlying JTextComponent Ctrl-C pops up the calendar and Ctrl-N sets the value to null.

• IDateEditor exposes the underlying DateFormat so it can be manipulated (for example setting a time zone)

• IDateEditor provides a method to retrieve the underlying JTextComponent.

Test Program

• New properties added so they can be exercised. The DateVerifier example excludes Mondays and otherwise includes only even numbered dates.

• For JDateChooser add a check box that sets the top four choosers to null when checked, today when not. Set them to null individually using ctrl-n when they have the focus.

• Set the nullText using the text field (requires cr).

Backwards compatible with 1.3.3 with the exception of keyboard behaviour.

UPDATES

JCalendar is updated from time to time. Development efforts will be added into this fork.
