Derived classes should return the component that represents whatever type of menu they implement.

Returns:

The menu component.

addToMenuContainer

public abstract void addToMenuContainer(MenuSubItemIF msi)

Derived classes must overload this method to add sub menu instances to their chosen type of top level component. We can't handle the addition at this level because there is no standard menu container i.e. the tool bar container is different from the menu bar.

Parameters:

msi - The item to be added.

removeFromMenuContainer

public abstract void removeFromMenuContainer(MenuSubItemIF msi)

Derived classes must overload this method to remove subitems from their menu component.

Parameters:

msi - The item to be removed.
