//
// "$Id$"
//
// MicroSoft style "ComboBox" with the menu appearing below with a
// scrollbar. I would like to use the name "ComboBox" or "InputChoice"
// for a more user-friendly version which uses pop-up menus and
// positions the menu with the cursor pointing at the current item,
// but this version can be used to get what MicroSoft users expect.
// The implementation is a good example of how to get a widget to appear
// in a modal pop-up window.
