ABSTRACT:
A multicasting system for multicasting window events to various application programs running on a computer system, each such program having an application window. A global control program runs on the computer system and has a global control window. Through the global control program, a user selects one or more of the application programs to receive incoming window events. Later, when the global control window is active, any incoming window event is received in that window. The global control program automatically multicasts each such event to every application program that the user has selected to receive incoming window events. Events may be multicast directly to child windows of the various application windows. The global control window may have a global child window that receives incoming window events; such events are multicast directly to selected child windows of the application programs. The application programs may be resident locally or on a remote computer system. If window events are received out of sequence, the global control program may either ignore them or resequence them for proper operation.
