public class PopupFactory extends Object
PopupFactory, as the name implies, is used to obtain
 instances of Popups. Popups are used to
 display a Component above all other Components
 in a particular containment hierarchy. The general contract is that
 once you have obtained a Popup from a
 PopupFactory, you must invoke hide on the
 Popup. The typical usage is:
 PopupFactory factory = PopupFactory.getSharedInstance(); Popup popup = factory.getPopup(owner, contents, x, y); popup.show(); ... popup.hide();

 is used to determine which Window the new

 is no valid parent. x and
