Comments

• If you prefer to let the user edit one of the container's contents by adding and removing items directly, invoke the Display Contents Of Container hook.
• The TwoTableFormSheet is based on two tables that display the contents of the data containers. It will provide two buttons with which the user can move items between source (left) and destination (right) container (table). The FormSheet's response to the user clicking one of the buttons is defined using strategies descended from data.stdforms.twotableformsheet.MoveStrategy . There are default implementations for all cases that are supported.

  The following combinations of source and destination are supported:

  Source	Destination	Default strategy
  CountingStock	CountingStock	data.stdforms.twotableformsheet.CSCSStrategy
  StoringStock	StoringStock	data.stdforms.twotableformsheet.SSSSStrategy
  CountingStock	DataBasket	data.stdforms.twotableformsheet.CSDBStrategy
  DataBasket	CountingStock	data.stdforms.twotableformsheet.DBCSStrategy
  StoringStock	DataBasket	data.stdforms.twotableformsheet.SSDBStrategy
  DataBasket	StoringStock	data.stdforms.twotableformsheet.DBSSStrategy
  Catalog	Catalog	data.stdforms.twotableformsheet.CCStrategy
  Catalog	DataBasket	data.stdforms.twotableformsheet.CDBStrategy
  DataBasket	Catalog	data.stdforms.twotableformsheet.DBCStrategy
  Catalog	StoringStock	data.stdforms.twotableformsheet.CSSStrategy Attention: You need to override the createStockItem() method, as it is application dependent.
  Catalog	CountingStock	data.stdforms.twotableformsheet.CCSStrategy

• There are default table layouts for each type of data container. If you want to know which, see the JavaDoc of the appropriate create method.

  If you need a different table layout invoke the Define New Table Layout hook.

• If you need to build your own FormSheets for data management classes, see package data.swing .
