| 36 | * A <code>Menu</code> object is a pull-down menu component |
| 37 | * that is deployed from a menu bar. |

| 39 | * A menu can optionally be a <i>tear-off</i> menu. A tear-off menu |
| 40 | * can be opened and dragged away from its parent menu bar or menu. |
| 41 | * It remains on the screen after the mouse button has been released. |
| 42 | * The mechanism for tearing off a menu is platform dependent, since |
| 43 | * the look and feel of the tear-off menu is determined by its peer. |
| 44 | * On platforms that do not support tear-off menus, the tear-off |
| 45 | * property is ignored. |

| 47 | * Each item in a menu must belong to the <code>MenuItem</code> |
| 48 | * class. It can be an instance of <code>MenuItem</code>, a submenu |
