Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of a window sharing system according to an embodiment of the present invention. The window sharing system of this embodiment is constructed on a normal workstation equipped with a keyboard, a mouse, a display and a server / client type window system.

In FIG. 1, a portion 1 surrounded by a broken line is a module group and a memory group for realizing the present invention, and the module / memory group 1 is a client application execution unit for executing a main program of a client application. 2, a communication unit 3 for communicating with a plurality of window system servers, an operation right management unit 4 for managing an operation right for a client application, and an operation for storing data managed by the operation right management unit 4. Right information memory 5, window information management unit 6 for managing information on windows created by client applications, window information memory 7 for storing window information managed by the window management unit 6, and window size change Window size to control the process It is constituted by a management unit 8.

The parts other than the module / memory group 1 are normally equipped in the workstation, and include the window system server 9 and the window manager 1.
0, an input device 11 such as a keyboard and a mouse, and a display 12 for displaying windows and various information. Further, the system of the present embodiment is connected to the system configured on another workstation as shown in FIG. 2 via the network by the communication unit 3. Therefore, FIG. 1 also shows the window system server 13 and the window manager 14 on other workstations.

In the window sharing system having the above-mentioned configuration, the process of setting the operation right, the process of acquiring information about the window created by the client application, and the window size adjusting process are performed independently. Hereinafter, these processes will be described individually.

FIG. 3 is a flowchart showing the procedure of the operation right setting process.

First, the system of the present embodiment is activated, and a command having an initial value as an argument is output to the operation right management unit 4 (step S1).

Next, the operation right management unit 4 determines whether or not the operation right is input (step S2). Step S
When the process proceeds from step 1 to step S2, the operation right is input, so the process proceeds to step S3.

In step S3, data indicating the operation right is written in the operation right information memory 5, and the process returns to step S2 and waits until the operation right is input. Then, when the user specifies the transfer of the operation right through the window system servers 9 and 13, the operation right specifying command is transmitted to the operation right management unit 4 through the communication unit 3, and the operation right is input in step S2. Since the operation right management unit 4 receives the command, the operation right management unit 4 receives the specified operation right information from the operation right information memory 5
(Step S3).

FIG. 4 is a flow chart showing a procedure of window creation or deletion processing by the client application, and this processing is performed by the window information management unit 6.

In the figure, first, when the client application execution unit 2 creates a new window,
The information about the window is transmitted to the window information management unit 6 via the communication unit 3, the determination is “YES” in the determination whether the window is added (step S11), and the window information management unit that has received the window information. 6
Writes the window information additionally to the window information memory 7 (step S12).

Next, when the client application execution unit 2 closes the window, ID information regarding the window is transmitted to the window information management unit 6 through the communication unit 3 and it is determined whether or not the window has been deleted (step S13). "YES" is determined and the window ID
Upon receiving the information, the window information management unit 6 deletes the information about the window from the window information memory 7 based on the window ID information (step S14).

When a new window is not created or a window is not deleted in the judgment of adding or deleting a window (steps S11 and 13), the process waits until the addition or deletion is designated.

FIG. 5 is a flow chart showing the procedure of window size adjustment processing.

When the user changes the size of the window using the input device 11, the change operation is requested to the window managers 10 and 14, and performed via the window system servers 9 and 13, respectively. When the window size is changed, the window system servers 9 and 13 notify the communication unit 3 of the fact, and the communication unit 3 notifies the window size management unit 8 that the window size has been changed, and the size is changed. Since it is determined "YES" in the determination (step S21) as to whether or not the change has been made, the process proceeds to step S22. Note that step S
If there is no window size change in the size change determination 21, the process waits until the size change is designated.

Next, the window size management unit 8 refers to the contents of the operation right information memory 5 and determines whether or not the operation right is designated by the user (step S22). At this time, if the designation is made by the user who has the operation right, the window size management unit 8 determines the portion related to the size of the designated window in the window information memory 7 based on the information regarding the designated window. The window size changing command is changed (step S23), the window size changing command is output to the client application execution unit 2, and the window rewriting process is performed for each window system server (step S24).

On the other hand, if it is determined by the user who does not have the operation right in the determination in step S22, the window size management unit 8 determines the designation in the window information memory 7 based on the information about the designated window. The window rewriting process is requested to the designated window system server based on the referred size information by referring to the portion related to the window size (step S).
