public class PopupMenu
A class that implements a menu which can be dynamically popped up at a specified position within a component.
As the inheritance hierarchy implies, a PopupMenu can be used anywhere a Menu can be used. However, if you use a PopupMenu like a Menu (e.g., you add it to a MenuBar), then you cannot call show on that PopupMenu.
