PopupMenu (Java 2 Platform SE 5.0)

java.awt
Class PopupMenu

java.lang.Object
  java.awt.MenuComponent
      java.awt.MenuItem
          java.awt.Menu
              java.awt.PopupMenu

All Implemented Interfaces:: MenuContainer, Serializable, Accessible

public class PopupMenu
extends Menu
extends Menu

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.

          throws HeadlessException

PopupMenu

public PopupMenu(String label)
          throws HeadlessException

Creates a new popup menu with the specified name.

Parameters:: label - a non-null string specifying the popup menu's label
Throws:: HeadlessException - if GraphicsEnvironment.isHeadless() returns true.
See Also:: GraphicsEnvironment.isHeadless()

addNotify

public void addNotify()

Creates the popup menu's peer. The peer allows us to change the appearance of the popup menu without changing any of the popup menu's functionality.

Overrides:: addNotify in class Menu

show

public void show(Component origin,
                 int x,
                 int y)

Shows the popup menu at the x, y position relative to an origin component. The origin component must be contained within the component hierarchy of the popup menu's parent. Both the origin and the parent must be showing on the screen for this method to be valid.

If this PopupMenu is being used as a Menu (i.e., it has a non-Component parent), then you cannot call this method on the PopupMenu.

Parameters:: origin - the component which defines the coordinate space; x - the x coordinate position to popup the menu; y - the y coordinate position to popup the menu
Throws:: NullPointerException - if the parent is null; IllegalArgumentException - if this PopupMenu has a non-Component parent; IllegalArgumentException - if the origin is not in the parent's heirarchy; RuntimeException - if the parent is not showing on screen

getAccessibleContext

public AccessibleContext getAccessibleContext()

Gets the AccessibleContext associated with this PopupMenu.

Specified by:: getAccessibleContext in interface Accessible
Overrides:: getAccessibleContext in class Menu

Returns:: the AccessibleContext of this PopupMenu
