Only one item in the Items hierarchy for TMenuItem can be the default menu
item. Changing the value for the property causes items on the parent menu item
to be visited and updated (when assigned). Another TMenuItem instance with its
Default property enabled is changed to <b>False</b> prior to updating Default
in the class instance. In addition, MenuChanged is called to signal the
OnChange event handler (when assigned). This allows a parent menu item to be
updated or rebuilt after the menu item has been changed.
