Abstract
An environment is emulated in a host environment. Output generated in the emulated environment is displayed in a window of the host environment. The emulated environment's output is in the form of Postscript commands that map to the entire screen. The host environment emulates the Postscript commands and maps the output to a window. Input associated with the window is retrieved by an event driver running in the host environment. Each instance of input is referred to as an event. Each event is translated into an event of the emulated environment by an event driver. A translated event is stored in shared memory for access by a window server. The event driver notifies the window server that one or more events are queued in shared memory. The window server processes the queued events by, for example, transmitting the event to an application running in the emulated environment.
