Member functions for the classes defined in LISTDB.H
- This class is used to present a generic ListBox lookup window for
- use with any of the object creation/selection choice widgets. This
- dialog window will present a (possibly) scrolling list of values
- that come from a data table source. Based on the object type passed
- in the constructor, a ListBox is built to present the user with a
- single selection listbox.
-
- The string selected from the list box is stored in the Global variable
- "ListDB_Seclection", and will remain set until another interation of this
- routine is called.
-
- For each object (database) type that is to be used, an overridden
- constructor should be written to appropriately link to the proper
- data table/object for building the list.

The data table record access is all handled through the routines
in this module, interfacing with the methods defined in wxTable.
- All objects which use data table access must be initialized and
- have opened the table prior to passing them in the dialog
- constructor, and the 'where' query should already have been set
- and performed before creating this dialog instance.
