## 18.44 java.awt.MenuItem (JDK 1.0)

###

This class encapsulates a menu item with a specified textual label. A `MenuItem` can be added to a menu pane with the `Menu.add()` method. The `disable()` method makes an item non-selectable; you might use it to "gray-out" a menu item when the command it represents is not valid in the current context. The `enable()` method makes an item selectable again. In Java 1.1, use `setActionCommand()` to specify an identifying string that is included in `ActionEvent` events generated by the menu item.

    public class MenuItem extends MenuComponent {
        // Public Constructors
            1.1  public MenuItem();
                public MenuItem(String label);
            1.1  public MenuItem(String label, MenuShortcut s);
        // Public Instance Methods
            1.1  public synchronized void addActionListener(ActionListener l);
                public void addNotify();
            1.1  public void deleteShortcut();
            #   public synchronized void disable();
            #   public synchronized void enable();
            #   public void enable(boolean b);
            1.1  public String getActionCommand();
                public String getLabel();
            1.1  public MenuShortcut getShortcut();
                public boolean isEnabled();
                public String paramString();  // Overrides MenuComponent
            1.1  public synchronized void removeActionListener(ActionListener l);
            1.1  public void setActionCommand(String command);
            1.1  public synchronized void setEnabled(boolean b);
                public synchronized void setLabel(String label);
            1.1  public void setShortcut(MenuShortcut s);
        // Protected Instance Methods
            1.1  protected final void disableEvents(long eventsToDisable);
            1.1  protected final void enableEvents(long eventsToEnable);
            1.1  protected void processActionEvent(ActionEvent e);
            1.1  protected void processEvent(AWTEvent e);  // Overrides MenuComponent
    }
