- When it's not actually popped up, a PopUpList stores its "current selection"
- in the title of the button that does the popping-up. When theuser presses
- that button, the button causes the popuplist to pop up; the popuplist
- queries the button's title, and searches for this title in its array of
- cells to determine which one to highlight. (If it's not there, it adds
- it --- see the popuplist docs.) To change the current selection, you can
- just use setTitle: on the button.
