public class Menu

extends TextControl

A drop-down menu which can be attached to a frame's menu bar or as a submenu of another menu. Menus can contain menu items and other submenus. They can also include separators, which appear as horizontal bars which divide the menu into separate sections. Unlike most other windows, menus cannot be given a size or position, and you cannot change their size or position.

Since menus are not containers, the parent window of all the menus and submenus in a frame will actually be the frame itself.
