public interface ContextGlobalProvider
Utilities.actionsGlobalContext()method and is expected to contain similar content as the context used when context aware actions (see
ContextAwareAction) are being manipulated for example via method
Utilities.actionsToPopup(javax.swing.Action, org.openide.util.Lookup), so in current state it is reasonable to put there all currently active Node, their cookies and
ActionMap. By default this interface is implemented by window system to delegate to currently activated TopComponent's lookup.
There is an external FAQ entry describing how to add content to the global context by providing customized implementation of this interface.
