ABSTRACT:
The present invention is directed to providing an ability to re-host, or port, an object oriented graphical user interface implementation from a native window-based platform, or environment, to another window-based platform, or environment. Exemplary embodiments abstract any notifications (e.g., events, state changes or "interests") which occur in the native environment as behavioral specifications. These behavioral specifications, (i.e., traits or protocols) can be used as part of a conformance negotiation to determine, during the execution lifetime of the graphical user interface, whether a particular client side object will conform with the behavioral specifications which have been abstracted from server side events associated with a different object. Where the conformance negotiation proves successful, abstract notifications can flow between particular instances of objects to model the state of the system, rather than using native implementations of events. During the execution lifetime, other objects can dynamically establish relationships with object classes containing abstracted notifications for the purpose of receiving the abstracted notifications.
