Package PamView

Class MenuItemEnabler

java.lang.Object
PamView.MenuItemEnabler
public class MenuItemEnabler extends Object
Now that there are many menus, there will several instances of each menu item. Each menu item may therefore be added to a MenuItemEnabler which will ensure that all items are enabled / disabled together.

Can also be used to setSelected

Reworked with a static list of all MenuItemEnablers so that when menus are removed from the system (which happens a lot !) they can be easily removed from all the Enablers.
