Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a multi-window display method in which a child window provided in a connotative relationship with a parent window on a display device screen can follow the parent window while maintaining that relationship. Regarding.

[Prior Art] When a user performs various operations while interacting with a system on the screen of a display device connected to a central processing unit, a rectangular logical frame is considered to be on the screen and is called a window. FIG. 3 shows a case where windows 1 to 7 are provided inside the physical screen 2 for the display device 1. That is, a plurality of windows are provided on the same physical screen 2, and each of them is considered separately, or they are partially overlapped as in window 1 and window 2. By associating one program with each window, the central processing unit can process a large amount of data in parallel. Further, each window can be moved vertically and horizontally on the screen as necessary, or windows that are no longer needed can be deleted, or new windows can be created.

[Problem that the invention attempts to solve] Connotational relatives of windows may also have other connotative relationships.

That is, windows 3, 4.5i are part of window 2 in FIG. 3, and window 6.7 is surrounded by window 5 and naturally also by window 2. In this case, when window 2 is moved to the right, windows 3 to 7 have to change their original positions because conventionally, there is no logical relationship between them and other windows that have a connotative relationship with window 2. There is no. Therefore, only window 2 moved to the right. After window 3, it was necessary to perform moving processing after that. In this case, it is said that there is no genetic basis for manipulation.

[Means for solving the problems] The means adopted by the present invention to solve the above-mentioned problems are as follows:
In a multi-window display system that can display windows that can be partially superimposed on the display device screen, a child window is provided in a contained relationship with a parent window, and the information held by the central processing unit for managing each window is An identifier is provided to identify that the window is a parent or child window and has that logical relationship, and a window movement operation program is processed with a constraint that does not allow the child window to move beyond the frame of the parent window.

[Effect] Each window's management information includes identifiers for the parent window and how many child windows there are, and for each child window, the parent window and its relationship with the parent. Since the operation is performed and the child window is checked to ensure that it does not exceed the frame of the parent window, the movement process is effective.

[Example] FIG. 1 shows a case where the parent window (2) and child windows (3) to (7) are moved to the right together from the state shown in FIG. 3 as an example of the present invention. . In Fig. 1, l is a display device, 2 is a physical screen, and 3 to 9 are windows (1) to
(7), window (2) is parent window 4 in this case, and windows (3) to (7) are child windows 5 to
9 and has a connotative relationship with the parent window 4.

To manage each window, the central processing unit retains information, including the position (size) of the normal window frame.
In addition to information related to information and data processing, the present invention provides an identifier for identifying whether the window is a parent window or a child window. In addition to the parent/child relationship, the identifier preferably includes data on how many children there are in the case of a parent, and data on the parent or the parent's relationship with the parent in the case of a child. When the window management program performs processing, it checks whether the identifier exists or not, and if the identifier exists, the processing of the child window is linked. Next, a list of operations for the window is shown in the table below. In the table, if there is a genetic relationship with a child window, the processing is always linked.

FIG. 2 shows a flowchart of processing operations.

○In step C1, a window operation command is input from the user or the program (control flow fl).The control flow f2 moves to step C2.The input command is analyzed in step C2.The control flow f3 moves to step C3.OStep C
Processing is performed only when the command input in step 3 is creation, combination, movement, or enlargement. Here, information regarding windows and parent-child relationships between windows held by the window management unit is referred to to check whether the child window does not exceed the frame of the parent window by executing the command.

O step C which moves to step C4 by control flow f4
In step 4, the command is executed by issuing an operation corresponding to the command to the window pipe section.

Control flow f5: Proceeds to step C5 according to f7.In step C5, information regarding windows and parent-child relationships between windows is maintained. It accepts operations corresponding to commands and acts on the information. In addition, in the case of deletion, movement, enlargement, and reduction commands, similar operations are performed on child windows as well.

Control flow f5 moves to step C6 O step C
In step 6, only in the case of deletion, movement, enlargement, or reduction commands, the screen is displayed by referring to information related to windows and parent-child relationships between windows held by the window management section.

Regarding the control flow, f6: Read information to check whether the child window exceeds the frame of the parent window.

f7: Update information regarding windows and parent-child relationships between windows.

f8: In the case of deletion, movement, enlargement, and reduction commands, similar operations are performed on child windows as well.

flo: Return to step C1 when there is a command syntax error.

fil: Step C1 if the child window exceeds the frame of the parent window in the case of create/combine/move/enlarge commands
Return to

f12: If it is a create/combine/cancel command, the process ends here.

If f13=delete/move/enlarge/reduce command, the process ends here.

[Effects of the Invention] As described above, according to the present invention, a child window that has a connotative relationship with a parent window is easily processed in conjunction with the operation of the parent window, which is effective in data processing.

Claims (1)

[Claims] In a multi-window display system that can display windows that can be partially superimposed on the display device screen, a child window is provided in a contained relationship with a parent window, and the information held by the central processing unit for managing each window is An identifier is provided to identify that the window is a parent or child window and has a logical relationship therewith, and the window movement operation program is characterized in that processing is performed with a constraint that does not allow the child window to move beyond the frame of the parent window.
