DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the configuration of the entire system including a window display system.

This system consists of multiple computers
The system is connected. In this embodiment, 2
Two computer systems 1 and 2 are provided. The computer systems 1 and 2 are provided with display devices 1A and 2A, an input device, etc., respectively. The window display system is realized as a part of each computer system.

FIG. 2 is a functional block diagram showing the configuration of the window display system.

The window display system includes a command receiving unit 11, a command determining unit 12, a display change processing unit 13,
It is composed of a window information storage unit 14, a display information storage unit 15, and a display control unit 16. Each of these parts 11-16
Is realized as a function achieved by a computer system that operates according to a window system program described later.

The command receiving section 11 is a section for receiving a command input directly from an input device (keyboard) of a computer system or via an application program. The command reception method differs depending on the operating system, etc. in which the window system program is installed. The received command is passed to the command determination unit 12.

The command determination unit 12 is a unit for determining the command input to the command reception unit 11, and the command input according to the determination result is sent to the display change processing unit 13 or another processing unit (not shown). hand over.

The display change processing unit 13 displays a predetermined window displayed on the screen of the display device 1A of the computer system 1 according to the command passed from the command determination unit 12 of the display device 2A of the computer system 2. Performs window move processing to move to the screen.

The window information storage unit 14 stores information about windows for displaying the windows on the display screen of the display device. This window information includes information about which computer system the display device is currently displayed on, information indicating the position and size of the window, information indicating characters, figures, etc. displayed in the window. included.

The display information storage unit 15 stores information about display processing used by the window system program.

The display control unit 16 controls the display, deletion, and other display of windows on each display device.

FIG. 3 shows an example of the data structure of a command for moving a window displayed on one display device to another display device (hereinafter referred to as "window moving command").

The "window move command" includes a code (or data) representing "command sender", "display source display device", "target window", "display destination display device" and the like.

"Command sender" is data relating to the user who has input this window move command.

The "display source display device" is data (identification code) indicating the display device displaying the "target window" to be moved.

The "target window" is data that specifies the window to be moved.

The "display destination display device" is data (identification code) indicating the display device on which the moved "target window" is to be displayed.

FIG. 4 is a flow chart showing a processing procedure according to the Unido system program.

The window W (FIG. 5 (A)) displayed on the display screen of the display device 1A of the computer system 1 is moved to the display screen (FIG. 5 (B)) of the display device 2A of the computer system 2. The case of making it will be described.

When a user of the computer system 1 inputs a command from the input device,
The command is received by the command reception unit 11 (step 21).

With respect to the input command, the process represented by the command is judged by the command judging section 12 (step 22).

When it is determined that the input command is not the "window move command" (NO in step 22), the process instructed by the command is performed (step 30).

When the input command is determined to be the "window move command" (YES in step 22), the "command sender" included in the window move command,
It is judged whether or not each data of the "display source display device", the "target window" and the "display destination display device" is appropriate (steps 23 to 26).

In step 23, whether the "command sender" who inputs the "window move command" can move the "target window" displayed on the display screen of the display device to the display device It is determined by referring to the window information and the display information based on the person's ID code or the like.

At step 24, it is judged by referring to the display information whether the "display source display device" exists in the entire system including this window display system.

At step 25, it is judged whether the "target window" exists in the display source display device by referring to the window information.

In step 26, "display destination display device"
Is determined in the system by referring to the display information.

If NO in any of the above steps 23 to 26, an error is judged (step 31).

For all steps 23-26 above
If YES is determined, the information about the display device in the window information about the target window is changed from the display source display device to the display destination display device (step 27). After that, the target window displayed on the screen of the display source display device is erased (see FIG. 6A), and the window information of the computer system 1 is transmitted to the computer system 2 and the target window is displayed. It is displayed on the screen of the destination display device (see FIG. 6B) (steps 28 and 29).

Operations such as input / output of data to / from the target window moved from the display source display device to the display destination display device are performed on the display destination display device in the same manner as on the display source display device.

An example in which this window display system is applied to an electronic conference system will be described below.

For example, one conference person transfers the window W on the display device 1A shown in FIG. 7 (A) to the display device 12 of another conference person shown in FIG. 7 (B).

While the conference is in progress, one conferee using the display device 1A tries to present new data (window) to another conferee using the display device 2A to proceed with the discussion. In the case of consideration, first, one conferee displays data (window W in FIG. 7A) on the display screen of the display device 1A, and makes necessary processing and display changes. After that, when one conference participant inputs a window move command, the display device 1A (FIG. 7 (A)
The window W displayed in () is transferred to the display device 2A. The window W of the display device 1A is erased (see FIG. 8A), and the window W is displayed on the display device 2A (see FIG. 8B).

At this time, the contents of the data displayed in the window do not depend on the window display system, and the normally used tools can be used as they are. In other words, it is not necessary to change the electronic conferencing system to accommodate new data.

In the prior art (for example, X Window), since the display device on which the window is displayed is fixed, the display contents cannot be changed after the window is displayed, but the window display device can do this.
That is, flexible display data (window) can be created.
