Abstract
An object oriented zooming engine for providing a zooming graphical user interface is disclosed. The zooming engine includes classes that define zooming objects, an event manager, and a view manager. Events are received by the event manager, and alternatively assigned to the view manager or zooming objects for processing. The view manager and zooming objects have associated event handlers for providing event responsive behavior. Among the event handlers associated with the view manager is a pick handler that determines whether zooming objects in a zooming view have been targeted by an event. Thus, an event can be initially assigned to the view, and then assigned to the zooming objects within the view that may have been targeted. This allows more efficient handling of events and updating of the display, and provides a flexible system, where various behaviors can be variously and individually modified.
