                  Accession.AccACCwizardPopup

All Implemented Interfaces:

java.awt.event.ActionListener, java.awt.event.ItemListener, java.awt.event.MouseListener, java.awt.event.WindowListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible

public class AccACCwizardPopup
extends java.awt.Frame
implements java.awt.event.ItemListener, java.awt.event.ActionListener, java.awt.event.MouseListener, java.awt.event.WindowListener

Class AccACCwizardPopup implements a popup GUI to create and edit the sample annotation used in the accessioning program. NOTE: in the future this will be depricated in favor of using PEDRo or a similar XML database editor program.

 [TODO] 
 For accession information, this code will either invoke
    a) initial single accession information Q&A window, or 
    a.1) Make dynamic list of acc fields. Refactor so can add/remove
         fields from Table file. Integrate into Accession.xml.
         [CHECK] effect on other Open2Dprot applications. Make
         hash table of (field names, field values) for extensions.
    b) a merged PEDRo/MIAPE Q&A.
