Abstract
A system, method and program product for controlling multiple appearances of data on a display. A Controller is provided for receiving user instructions for data to be displayed, and for generating model management and view management instructions for controlling the appearance of data to be displayed. A Model is connected to the Controller for receiving model management instructions from the Controller, and for keeping track of changes to the appearance of data to be displayed. A ViewProxy is connected to said controller for receiving view management instructions, and connected to said Model for receiving model change notifications responsive to changes in the appearance of data to be displayed. Multiple Views are connected to the ViewProxy for receiving model change notifications. The ViewProxy determines to which Views the model change notifications are to be sent, and sends model change information to only those Views affected by said model changes. A windowing system displays only active Views, and switches between Views by making at least one View active and selected other Views inactive.
