It includes a drawing information output means 13 and a window information management section reference means 14 that refers to the window information management section 8.

The command processing unit 6 interprets the commands sent from the input/output control unit 5 according to a predefined grammar, and generates a series of command strings 32 (see FIG. 3) based on the interpreted command contents. The window information management unit 8 issues instructions to call processing procedures and sends a series of command sequences 32 to the window information management unit 8.
command interpretation and modification of the series of command strings 32 stored in the window information management section 8, extracting the series of command strings from the window information management section 8, and issuing drawing instructions to display drawing contents. A command processing means 15, a processing procedure calling means 16 that calls a corresponding processing procedure based on an instruction from the command interpretation/command processing means 15, and a series of command strings 32 etc. generated by the command interpretation/command processing means 15. A window information management unit reading/writing unit 17 that stores various information in the window information management unit 8 and retrieves it from the window information management unit 8, and input/output control of window drawing instructions passed from the command interpretation/command processing unit 15. and a drawing instruction sending means 18 for sending the drawing instruction to the drawing section 5.

The processing procedure unit 7 is for executing internal processing procedures such as database operations and numerical calculations based on instructions from the command processing unit 6.

The window information management unit 8 uses the window identification number 31
The window information 23 includes a series of command strings 32 that generate drawing instructions for each window (see Fig. 3), and window drawing position/rank information 33 (see Fig. 3) indicating the display position and display order of each window. It also manages the window logical structure 21 (see Figure 2) that represents the logical connection between each displayed window and the re-execution pointer 22 (second window) that represents which window has been reproduced.
(see figure).

FIG. 2 is a diagram showing the internal configuration of the window information management section 8. As shown in FIG. The window information management unit 8 includes a window logical structure 21, a re-execution point 22, and window information 2.
3 is stored. Window logical structure 21 and re-execution pointer 2 stored in window information management unit 8
The contents and number of 2 vary depending on the logical tree structure of the displayed window. Here, a logical tree structure of windows means that when the processing of another window is performed based on the display contents of one window, a parent-child relationship is introduced between those windows, and the two windows of the former are The latter window is called a parent or ancestor window, and the latter window is called a child or descendant window, and the parent-child relationship of these windows is expressed as a tree structure.

For example, considering the parent-child relationship between windows represented by a tree structure as shown in Figure 4, window W is the one processed using the data of window W, and window W, . W1. represents the processing performed using the data of

For example, windows,W,,,W,, and,W,3,are windows that perform processing to search,table data from a database, windows that perform processing to specify,a range of data from the retrieved table data, and windows that,process graphs for data in the specified range. This corresponds to a case where each window corresponds to a window that performs drawing processing.

FIG. 4 is a diagram showing an example in which the specific contents of Windows 2 and 2 are expressed according to the parent-child relationship of windows represented by the tree structure of FIG. 4;

The window logical structure 21 is the terminal window (W+□) of the window tree structure.

W, 1! A re-execution pointer 22 is added to each window logical structure 21.

Next, the operation of the display window management system of this embodiment configured as described above will be explained.

■ Creation of initial window When an information processing system capable of multi-window display is started up, an initial window is displayed on the display device 4.

When a user starts up an information processing system that can display multiple windows, the window information management unit 8 first stores the window logical structure 21° re-execution pointer 2 of the initial window.
2 and window information 23 are stored from an auxiliary storage device (not shown) or the like.

In the command processing unit 6, the command interpretation/command processing means 1
5 reads the window information 23 from the window information management unit 8 using the window information management unit read/write means 17 based on the window identification number 31 of the initial window, processes the command string 32 in the window information 23, and generates an initial window. A drawing instruction (including the window identification number 31, the same applies hereinafter) is generated, and the generated drawing instruction is sent to the input/output control unit 5 by the drawing instruction sending means 18.

In the input/output control section 5, the drawing information output means 13 receives the drawing instruction sent from the command processing section 6, and uses the window information management section reference means 14 to select the window of the window information management section 8 based on the window identification number 31. With reference to the drawing position/rank information 33, a drawing instruction for generating an initial window is converted into drawing information for drawing an initial window, and this drawing information is output to the display device 4 via the interface means 11.

As a result, an initial window is generated and displayed on the display device 4.

■ Calling a processing procedure By inputting a processing procedure calling command from the display state of a window, the user can cause the processing procedure unit 7 to perform a processing procedure corresponding to the window and display the processing result in the window. It can be displayed in a child window that is newly generated according to the processing result.

When a user inputs a processing procedure call command from the input device 2 to a window for performing a certain processing procedure, this processing procedure call command is passed to the command sending means 12 via the large interface means 11, and the command sending means 12 The command is sent to the command processing unit 6.

In the command processing unit 6, the command interpretation/command processing means 1
5 interprets the sent processing procedure call command according to a predefined grammar, calls the processing procedure unit 7 by the processing procedure calling means 16, and gives necessary processing instructions. At the same time, directive interpretation and
The command processing means 15 generates a series of command strings capable of reproducing necessary processing instructions, and the window information management section read/write section 17 converts the command strings 32 corresponding to the corresponding window identification numbers 31 of the window information management section 8 into to add.

The processing procedure section 7 performs the corresponding internal processing based on the necessary processing instructions given from the command processing section 6, and if the necessary processing instructions include an instruction to output and display the processing results, An instruction for outputting and displaying the processing result is returned to the command processing unit 6.

Note that the processing result data itself that is necessary for outputting the processing result is stored, for example, in a temporary data storage section (not shown) provided on the main memory 3 or an auxiliary storage device (not shown). The data stored in this -time data storage section is read out and used as appropriate when drawing a window.

In the command processing section 6, the instruction for outputting and displaying the processing result returned from the processing procedure section 7 is received by the instruction interpretation/command processing section 15 via the processing procedure calling section 16. 15 interprets instructions for outputting and displaying processing results according to a predefined grammar.

If the instruction for outputting and displaying the processing result indicates drawing the processing result on the window into which the processing procedure call command was input, the instruction interpretation/command processing means 15:
An instruction for outputting and displaying the processing result is converted into an instruction to draw the processing result on a window, and the drawing instruction sending means 18 sends the drawing instruction to the input/output control section 5.

Further, when the instruction for outputting and displaying the processing result indicates the generation of a new window, the command interpretation/command processing means 15 converts the instruction for outputting and displaying the processing result into the drawing instruction for generating the window. The drawing instruction sending means 18 sends the drawing instruction to the human output control section 5. At the same time, the command interpretation/command processing means 15 generates a series of commands that can reproduce the drawing instruction to generate a window based on the drawing instruction to generate a window, and assigns a new window identification number 31. The window drawing position/rank information 33 is added and stored in the window information management section 8 by the window information management section reading/writing means 17.

In addition, the command interpretation/command processing means 15 uses the window logical structure 21 and the re-execution pointer 2 because the generated window is the lowest level window in the tree structure.
2, the window information management section reading/writing means 17
The information is stored in the window information management unit 8 by the following.

In the input/output control section 5, the drawing information output means 13 uses the window information management section reference means 14 to manage window information based on a drawing instruction for the processing result of a window or a drawing instruction for generating a window from the command processing section 6. Part 8
With reference to the window drawing position/rank information 33, etc., the processing result is converted into drawing information for drawing the processing result on the designated window of the display device 4 or drawing information for generating and drawing a new window, and this drawing information is Interface means 1
1 to the display device 4.

As a result, the processing result of the processing procedure is displayed on the display device 4.

By repeating the process of calling the processing procedure described above, the window information management section 8 generates and displays a window, displays the processing result of the processing procedure, and at the same time stores a command string.

This accumulation of command strings is performed on a window-by-window basis, and the command string 32 is sequentially accumulated in the window information 23 for each generated window.

■ Modifying the window display contents By inputting a window modification command, the user can
You can modify the window display contents.

When the user inputs a window modification command from the input device 2, this window modification command is sent to the interface means 1.
1 to the command sending means 12, and the command sending means 1
2 is sent to the command processing section 6.

In the command processing unit 6, the command interpretation/command processing means 1
5 interprets the sent window modification command according to a predefined grammar, and the window information management section reading/writing means 17 reads a series of command strings 32 corresponding to the corresponding window identification number 31 of the window information management section 8. Fix it.

Also, at this time, the re-execution pointer 22 corresponding to the window logical structure 21 that includes the window whose command string 32 has been modified is set for the window that has accepted the window modification command. After the command string 32 has been modified, the command interpretation/command processing means 15 retrieves the corrected series of command strings 32 from the window information management section 8 using the window information management section reading/writing means 17, and calls the processing procedure (2). In the same manner as in the above case, the modified display contents of the window are drawn on the display device 4.

As a result, the display content of the modified window becomes different from the display content of the previous window having the same window identification number 31.

(2) Reproducing and displaying a window The user can reproduce and display a window based on the window information 23 and the like stored in the window information management section 8 by inputting a window reproduction and display command.

When a window reproduction display command is input from the input bag W2, this window reproduction display command is sent to the interface means 1.
1 to the command sending means 12, and the command sending means 1
2 is sent to the command processing unit 6.

In the command processing unit 6, the command interpretation/command processing means 1
5 interprets the sent window reproduction display command according to a predefined grammar, and acquires a series of command strings 32 from the window information management section 8 based on the window identification number 31 by the window information management section reading/writing means 17. Then, the window is reproduced and displayed in the same manner as in the case of calling the processing procedure (2).

Additionally, when you modify the display content of the window in ■, the modified window display content will not be reflected in the display content of the child window, so there may be a conflict between the display content of both windows. be. In such a case, by inputting a window reproduction display command for the child window from the input device 2, the user can resolve the inconsistency in the display contents between the windows. That is, the command processing unit 6 refers to the window logical structure 21 and the re-execution point 22 based on a window reproduction display command from the user, and reproduces and displays the child window according to the display contents of the parent window. When the child window is reproduced and displayed, a re-execution pointer 22 is set for the reproduced child window. By giving a reproduction display command from a certain parent window to the terminal window, it is also possible to continuously reproduce the display for all descendant windows.
In this case, a re-execution pointer 22 is set for the terminal window.

■ Creation of another window Even if a child window is created and displayed due to a processing procedure call command that was previously input in a parent window, the user cannot perform another process on the same parent window. By inputting a procedure call command from the input device 2, another child window can be generated and displayed. For example, after drawing a graph for the searched table data, This is the case when you want to draw another graph for the data.

When the user inputs another processing procedure call command from the input device 2, a window is generated and displayed in the same manner as in the case of calling the processing procedure (2). It goes without saying that the window newly generated in this way is given a new window logical structure 21 and a re-execution pointer 22, since it becomes the lowest level window in the tree structure.

■ Deleting a window By issuing a window deletion command to a certain window, the user can delete all descendant windows from the window to be deleted.

When a window deletion command is input from the input device 2, this window deletion command is passed to the command sending means 12 via the interface means 11, and is sent to the command processing section 6 by the command sending means 12.

In the command processing unit 6, the command interpretation/command processing means 1
5 interprets the sent window deletion command according to a predefined grammar, and uses the window information management section reading/writing means 17 to create a window logical structure 21.5 regarding the window to be deleted and all descendant windows of that window. The re-execution pointer 22 and window information 23 are deleted from the window information management section 8. The command interpretation/command processing means 15 also sends a drawing instruction to the input/output control unit to delete the window to be deleted displayed on the display device 4 and all descendant windows of the window by the drawing instruction sending means 18. Send to 5.

The input/output control unit 5 converts all drawing instructions into drawing information and outputs it to the display device 4. As a result, the display device 4
All descendant windows of the window to be deleted are deleted.

Note that it is also possible to prompt the user to confirm when deleting a window.

By the way, the present invention is not limited to this embodiment, and in particular, the format of internal representation of the window information management section 8 of this embodiment is not limited to the formats of representation shown in FIGS. 3 and 5.

In addition, for example, in order to save the display contents of the window, the input/output control unit 5
By retaining a series of drawing instructions sent to , it is possible to quickly draw the window when there is no instruction to modify the display contents of the window, thereby increasing the effect of the display window management method of the present invention. It is possible to further increase the

〔Effect of the invention〕

As explained above, the present invention manages and reuses a series of command sequences that generate the display contents of a window for each window, and manages logical connections between multiple windows using a window logical structure and a re-execution pointer. By doing so, it is possible to maintain logical consistency between windows even when the display contents of the windows are modified.
