Abstract
A zooming engine for displaying zooming objects residing in a zooming space is disclosed. The zooming objects may be defined by a class in an object oriented architecture. The zooming objects are displayed on a display which provides a zooming view. A view manager manages the zooming objects that reside in the zooming view. Responsive to an event, such as the user's clicking on a viewed zooming object using mouse controls, a pick handler that is associated with the view manager determines which zooming objects in the view are targeted to process the event. The pick handler has a picking policy that is used to determine whether a zooming object is targeted to process an event. Providing the view manager to manage the zooming objects in the zooming view, along with a separate pick handler that can be interchangeably associated with the view manager allows the policy for responding to an event to be altered by merely introducing a new pick handler, without requiring reconfiguration of the view manager or zooming object classes.
