Class PopupMenu

All Implemented Interfaces:
MenuContainer, Serializable, Accessible

public class PopupMenu 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.

    • getParent

      public MenuContainer getParent()
      Returns the parent container for this menu component.
      Overrides:
      getParent in class MenuComponent
      Returns:
      the menu component containing this menu component, or null if this menu component is the outermost component, the menu bar itself
    • 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 hierarchy
      RuntimeException - if the parent is not showing on screen
    • getAccessibleContext

      public AccessibleContext getAccessibleContext()
