Intermediate user-interface definition method and system

A user-interface system and method that includes object-oriented user-interface definitions. User-interface definitions for objects of an application program are created using an interface definition language. An application programming interface provides access to the user-interface definitions. For each user-interface request, the application programming interface is used to obtain the user-interface definition for the referenced object. Responsive to the user-interface definition of the object, user-interface data is dynamically generated by an interface driver. By separating user-interface definitions from the interface driver, modifications to an application program and the corresponding user-interface definitions do not require enhancements to the interface driver.
