Abstract
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.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
138 words
In a computer system running a plurality of mutually independent application programs each having an associated window on a display screen, each such program being unaffected by events that occur outside its associated window, an improvement that enables the computer system to multicast window events to the application programs, the improvement comprising: a global control program running in the computer system, the global control program responsive to a command from a user of the computer system to designate a plurality of the application programs to receive incoming window events, and a global control window on the display screen, the global control program operative only when the global control window is active to receive an incoming window event in the global control window and to multicast the incoming window event to the windows associated with the designated application programs.
Claim 2
Dependent Claim
138 words
In a computer system running a plurality of mutually independent application programs each having an associated window on a display screen, each such program being unaffected by events that occur outside its associated window, an improvement that enables the computer system to multicast window events to the application programs, the improvement comprising: a global control program running in the computer system, the global control program responsive to a command from a user of the computer system to designate a plurality of the application programs to receive incoming window events, and a global control window on the display screen, the global control program operative only when the global control window is active to receive an incoming window event in the global control window and to multicast the incoming window event to the windows associated with the designated application programs.
Claim 3
Dependent Claim
45 words
An improvement as in claim 1 wherein: the computer system comprises a host computer and a remote computer in communication with each other; at least one of the application programs resides in the remote computer; and the global control program resides in the host computer.
Claim 4
Dependent Claim
45 words
An improvement as in claim 1 wherein: the window associated with one of the designated application programs has an application child window; and the global control program is operative to multicast a window event received in the global control window to the application child window.
Claim 5
Dependent Claim
52 words
An improvement as in claim 3 wherein: the global control window includes a global child window for receiving window events; and the global control program associates the global child window with the application child window, whereby a window event received in the global child window is multicast to the application child window.
Claim 6
Dependent Claim
50 words
An improvement as in claim 3 wherein: the computer system comprises a host computer and a remote computer in communication with each other; the application program associated with the window having the application child window resides in the remote computer; and the global control program resides in the host computer.
Claim 7
Dependent Claim
37 words
An improvement as in claim 1 wherein designating a plurality of the application programs to receive incoming window events comprises associating the global control window with the application windows of each of said plurality of application programs.
Claim 8
Dependent Claim
57 words
An improvement as in claim 6 wherein: the global control window includes a global field for receiving window events; and the global control program associates the global field with corresponding fields in a plurality of the application windows, whereby a window event received in the global field is multicast to the corresponding fields in the application windows.
Claim 9
Independent Claim
86 words
