All items in a menu must belong to MenuItem class or a subclass..

The default menu item represents a simple labeled menu item.

The picture of a menu bar (page II-188) shows five menu items. The first two are simple menu items labelled "Basic" and "Simple". Following it is a separator (see §1.32.1). Next is a CheckboxMenuItem (II-§1.7) labelled "Check". Finally, there is a submenu labelled "More Examples", which is an instance of Menu (II-§1.29).

When a menu item is selected, the AWT sends an action event (II-§1.14.13) to the menu item's containing frame. The event's target is the menu item, and its object is the string label of the menu item. Note that the subclass Menu overrides this behavior and does not sent any event to the frame until one of its subitems is selected.



public MenuItem(String label)
Constructs a new menu item with the specified label.
The label "-" is reserved to mean a separator between menu items. By default, all menu items except for separators are enabled.
label - the label for the menu item



public void addNotify()
This method calls the createMenuItem method (II-§1.41.16) of this object's toolkit (II-§1.10.20) in order to create a MenuItemPeer (II-§3.15) for this menu item. This peer allows the application to change the look of a menu item,without changing its functionality.

Most applications do not call this method directly.


public void disable()
Disables this menu item. It can no longer be selected by the user.


public void enable()
Enables this menu item; it can be selected by the user.


public void enable(boolean cond)

public String getLabel()

public boolean isEnabled()
