| ActionManager | | final public class ActionManager (Code) | | Central repository for all Actions.
On startup, the application is responsible for registering all actions via the
ActionManager.register(java.lang.String,javax.swing.Action) method. Once this is done, any action can be retrieved via the
ActionManager.get(java.lang.String) method.
The action manager will look for an actions.properties file in the same package, and will read all properties
specified in it for a given action.
The benefit of specifying actions in the external file is that actions themselves need not be aware of their textual or
graphic representation or key bindings.
