public class PopupList
A PopupList is a list of selectable items that appears in its own shell positioned above its parent shell. It is used for selecting items when editing a Table cell (similar to the list that appears when you open a Combo box). The list will be positioned so that it does not run off the screen and the largest number of items are visible. It may appear above the current cursor location or below it depending how close you are to the edge of the screen.
