Class PopupFactory

Contents

  • 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();
    Since:
    1.4

               throws IllegalArgumentException
        Creates a Popup for the Component owner containing the Component contents. owner is used to determine which Window the new Popup will parent the Component the Popup creates to.

        owner - Component mouse coordinates are relative to, may be null
        contents - Contents of the Popup

        Popup containing Contents
        Throws:
