List Edit Controls
The list edit control allows the user to enter a selection in the edit area, or, by left-clicking on the arrow, will display a drop-down list of possible choices. If the user clicks on an item in the list, the item is copied into the edit area.
The list of choices available for list edit objects may be modified only under program control. Values in the list may be accessed using a zero based list index integer.
