public class MenuBar
extends JMenuBar
implements Externalizable

An extended version of swing's JMenuBar. This menubar can load its content from the folder where its "disk image" is stored.

Moreover, menu is Externalizable to restore its persistent state with minimal storage expensiveness. The MenuBar recognizes following objects in the folder:

• subfolders - they're turned into top-level JMenu instances
• instances of Component - they're added directly to the menubar.
• instances of Presenter.Toolbar - their toolbar presenter is added to the menubar.

before OpenAPI version 3.2, only subfolders were recognized.

In subfolders the following objects are recognized and added to submenus:

• nested subfolders - they're turned into submenus
• instances of Presenter.Menu
• instances of JMenuItem
• instances of JSeparator
• instances of Action
• executable DataObjects
