Abstract

A window manager process hosts proxy window objects created by an application in a window manager display structure. A process in a device creates a local proxy view object within a window manager display structure for the window manager process. The process registers an identifier for a remote proxy window object which corresponds to an application display structure. The application controls processing of data used by the application. The process assigns the identifier for the remote proxy window object to the local proxy view object in the window manager display structure to create a composite display structure and renders the composite display structure to display an image on a display device. The image corresponds to the objects of the application display structure represented by the remote proxy window object. The window manager process controls rendering of the composite display structure.
