Using a model to represent the overall state of a view

Is there a standard practice for representing the state of a user interface that is not associated with a single component?

For example, the Swing interface may have a number of tabs with the restriction that one tab should be displayed only once for a given type of entity (this can be represented as a HashSet). Or the message may give the result of the last operation performed. Or a JPanel may be associated with an instance of a single object for editing purposes.
