Hi Folks,

Never mind my previous post. I have found an undocumented Date and Time
Field that is better than mine that comes bundled with Swing 1.01.

There is a class called DateChooser that is found in the src.zip archive
in the com/sun/swing/pending directory. With a little modification of the
source code it is possible to get this Date and Time Field component to
work with Swing.

Here are some hints:
1)Change the inheritance of DateChooser from Container to JComponent
2)Change the methods used to reference the  combo box to current Swing 1.0
methods.

combo.addPossibleValue() becomes combo.addItem().
combo.setCurrentValueIndex() becomes combo.getSelectedIndex()

3) Add the missing methods to the SyncTypeComboBoxEditor class of which
your compiler will complain about. These can be do-nothing methods.

4) Only uses the TINY size for this component. The other sizes have
problems.


That's it.
