A method and system are disclosed which may be utilized to generate a simultaneous presentation within a data processing system of video data within multiple windows supported by different graphic user interfaces. Each graphic user interface is coupled to a separate display device driver. Window movements including: creation; deletion; resizing; movement; minimization; maximization; activation; enablement; or an alteration in relative background/foreground order are detected for each graphic user interface and that information and the associated display device driver for each graphic user interface are coupled to a virtual device driver which facilitates interprocess communication between two or more graphic user interfaces, wherein the portion of the video display which is managed by each graphic user interface may be ascertained. Each separate display device driver is then coupled to a single display device, wherein multiple windows supported by different graphic user interfaces may be simultaneously presented.

Method and system for simultaneous presentation of multiple windows

A method of passing data between objects located distributed among a plurality of virtual address space domains established by processes executing on a data processing system comprises several steps. First, a session initiation message from a source object in a domain is broadcast to other objects in the domain. Responsive to receipt of the session initiation message by a domain agent (a type of object) for the domain, forwarding the session initiation message from the domain agent to each of a plurality of domain agents in other virtual address space domains. Responsive to receipt of the session initiation message by the domain agent for a second domain, transmitting the session initiation message from the domain agent for the second domain to an agent object in the second domain for the source object. Finally, responsive to receipt of the session initiation message by the agent object for the source object, establishing a session between the agent object for the source object and a target object for passage of data.
