Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a window display control device for displaying a plurality of window screens in an overlapping manner.

In recent years, with the spread of display devices for displaying a multi-window screen, improvement in operability for operators is required. For example, in a screen configuration in which multiple windows are arranged at arbitrary specified positions, overlap occurs depending on the size of the screens, and when a screen is displayed in the foreground (the window is activated), another screen displays There is a problem that it is hidden on the screen and cannot be referenced. In this case, the operator displays the reference data by performing an operation such as shifting the window position, but an operation to return it to the original position is also required, and the operation is extremely troublesome.

Therefore, it is required to easily improve the visibility of data in a hidden window.

[0004]

2. Description of the Related Art FIG. 7 is an explanatory view of a conventional example. FIG. 7 shows a window screen in the case of performing member withdrawal processing as an application example of the multi-window system. The member withdrawal processing screen is displayed in the illustrated window A, and the member personal information search screen is displayed in window B. It

When performing the withdrawal process, first, as shown in (1) of FIG. 7, a window B for retrieving personal information is displayed in the front (the personal information retrieval process is activated), and the withdrawal target personal information is displayed. (Withdrawal requests are recorded in advance) are sequentially searched and displayed in window B. When this member withdrawal process is performed, when window A is activated with a mouse or the like, window A is displayed in front of window B as shown in (2) of FIG. 7, and member withdrawal process becomes possible. .

Here, the member No. is required to input the data for the withdrawal process, and the operator refers to the member No. on the window B to input. In this case, remembering the member number on the screen of (1) and inputting it on the screen of (2) may forget the member number, which is inefficient.
It is desirable to input while referring to the member number of window B on the screen of (2). However, on the screen of (2), the member N
O is hidden in window A and disappears. Therefore, as shown in (3) of FIG. 7, the operator moves window B to the lower part of the screen with a mouse or the like, displays the member number and displays the member number of window A. Input in the section of from the keyboard.

[0007] Other items may be automatically entered from the personal information by the entered member number or may be input by operation, but at least the member number which is a key of the personal information is required. Then, the top data of the personal information in the window B is referred to.

When the withdrawal process of a member is completed in this way, the window B is activated to retrieve the next personal information, and after the personal information is displayed, the window A is switched to the withdrawal process. When the personal information is searched again, the display position of the window B is returned to the original position if it is necessary to see the entire personal information.

[0009]

In the above-mentioned screen structure for displaying a plurality of windows in an overlapping manner, for example, 2
When processing is performed while referencing data to each other across two windows, if the windows to be referenced overlap and the screen to be referenced disappears, the position of the other window must be moved or resized each time. Is cumbersome and inefficient.

It is an object of the present invention to provide a window display control device which eliminates the above-mentioned troublesomeness of the window operation when an operator performs a parallel work on a plurality of windows.

[0011]

In order to achieve the above object, the window display control device of the present invention manages the display position and size of the window as shown in the principle diagram of the present invention of FIG. In the window display control device having the window management information 20 and the window display control unit 21 that displays a plurality of windows based on the window management information 20, when the window switching is instructed, the window displayed in the window after the switching is the front window. An overlap determination unit 22 that determines whether or not there is an overlapping window based on the window management information 20 and that calculates the amount of overlap, and a data display that changes the data display start position in the overlapping window according to the amount of overlap. A window that overlaps the front window when switching windows Predetermined data of the overlapping portion by changing the data display start position configured to display in the visible region of the window. (2) In the above (1), the window definition information 24 that defines the necessity of changing the data display start position for each window is provided, and the data display start position changing unit 23 refers to the window definition information 24 and there is overlap. In addition, the processing for changing the data display start position of the window that needs to be changed is configured.

[0012]

[Action]

(1) When the window switching is instructed, the overlap determination unit 22 determines whether or not there is a window that overlaps with the window displayed in the foreground in the window display after the switching, based on the window management information 20, and the overlap is performed. Calculate the quantity. For windows that are determined to overlap, the data display start position changing unit 23 changes the data display start position in the windows according to the amount of overlap.

As a result, the data to be referred to is displayed in the visible area that does not overlap the front window, and the operation such as moving the position of the window becomes unnecessary. (2) In (1) above, if there is a window that does not need to change the data display start position, specify it in the window definition information 24, and the data display start position change unit 23 is specified in the window definition information 24. Change the window only.

As described above, the reference data can be displayed in the visible region by changing (scrolling) the data display start position in the window without moving the window position, and the window can be displayed by operating the mouse or the like. Freed from the hassle of moving.

FIG. 2 is a block diagram of an embodiment, FIG. 3 is a diagram showing an example of window management information, FIG. 4 is a diagram showing an example of window definition information, FIG. 5 is a processing flowchart diagram, and FIG. 6 is an example of implementation results. It is a figure showing.

In this embodiment, an example will be described in which parallel processing is performed while switching between the two-window screens (window A and window B) for withdrawal processing and personal information retrieval described in the conventional example. Also, of the data in the window,
An example in which, when the data of the first row overlap, the first row is displayed in the first row of the lower visible region is shown. Therefore, in the case of the example in FIG. 6, since the window A does not need to be changed, it is defined as unchanged in the window definition information.

Although various methods of displaying the window screen have been considered and are not limited to the present embodiment, here, the screen data to be displayed in the window is cut out from the original screen data and stored in the window screen memory. Aside
Each time the window is switched, the two-window screen is re-edited into one screen and dot-expanded and displayed in the VRAM.

Further, the change of the data display start position of the rear window is realized by changing the cutout start position of the original screen data and re-storing it in the window screen memory. After this processing, the above-mentioned re-editing processing is performed and dot development is performed and displayed in the VRAM. In this embodiment, the display start position is changed so that the data on the first line is displayed at the beginning of the visible area. Therefore, on the display screen, the data in the window switched to the rear is scrolled by the amount of overlap. Will be done.

In FIG. 2, reference numeral 2 denotes a screen memory, which is composed of a screen memory in which input screen data for withdrawal processing is stored and a screen memory in which screen data describing personal information is stored.

Reference numeral 3 denotes a withdrawal processing unit which, when activated, expands an input screen for withdrawal processing in the screen memory 2, and when it is displayed in the foreground, it becomes a data input / output processable state, and based on the input data. Perform a predetermined withdrawal process.

Reference numeral 4 is a personal information retrieval section, which is a personal information file.
The withdrawal member personal information is retrieved from 19 and stored in the corresponding screen memory 2. An input unit 5 includes a keyboard for inputting data, a scroll operation unit 6 for scrolling with a mouse or the like, and a window operation unit 7 for switching windows.

A window screen memory 8 stores screen data corresponding to the window size managed by the window management information 14. The initial value of the data display start position is the origin of the screen data and is moved by scrolling.

A window control unit 9 discriminates window operation and scroll operation of the input unit 5, and performs window control such as window display / switching instruction and scroll instruction to the window display control unit 10.

A window display control unit 10 stores screen data in the window screen memory 8 for scroll display,
The window switching display and the like are performed, and the overlap determination unit 11 and the data display start position change unit 12 determine the overlap amount and perform a data display start position change process (scroll process) described later. Note that the scroll amount of this process is held in the window management information 14, and at the time of restoration, a process of returning to the original amount by the scroll amount is also performed.

Reference numeral 14 is window management information, and as shown in FIG. 3, the window name (display position, size (X, Y coordinates), scroll amount in the present invention is recorded and managed. These values are determined by business processing. Is not always fixed, and the value changed by the window operation is set by the window control unit 9.

Reference numeral 15 is window definition information, and as shown in FIG. 4, whether or not the data display start position is changed is preset. Only in the case of "Yes" and when there is an overlap,
Change the data display start position.

Reference numeral 16 is a VRAM, and as shown in FIG. 6, the screen in which the windows A and B are combined is subjected to dot expansion. A display control unit 17 repeatedly reads the VRAM 16 and displays it on the display unit 18.

Reference numeral 19 is a personal information file in which personal information is stored with the member number as a key. Reference numeral 10 denotes a central processing unit CPU, which controls each of the above-mentioned units and operates a multi-window system.

In the multi-window system having the above configuration, the following processing is performed when switching windows. See Fig. 5 (1) Click the window (Window A in Fig. 6) to be activated with the mouse. As a result, the window control unit 9 issues an instruction to the window display control unit 10 to switch the display window (active window) from the window B to the window A. (2) First, display processing of a display window (window A) that can be newly switched to the foreground is performed. That is, the data display start position of the display window is changed to the original position. In the present embodiment, since the upper part of the window A is not overlapped with other windows, the display position change is defined as “none” in the window definition information 15, and the data display start position has not been changed, so it is necessary to restore it. However, when switching from the window A to the window B, the window is scrolled in the reverse direction by the previous scroll amount stored in the window management information 14 and returned to the original state. (3) Next, the display process of the window that becomes the rear surface is performed. First, the overlap determination unit 11 refers to the window management unit 14,
From the display position and size of window A and window B,
Verify whether window B overlaps window A. In the example of FIG. 3, the display area of the window A in the Y direction is 3 to 13 lines, and the start point position of the window B is the 9th line. Therefore, it is determined that there is overlap, and the overlap amount is 13-9. = 4 lines. Therefore, it is sufficient to scroll four lines. Since the change of the data display start position of the window B is defined as “present” in the window definition information 15, the display start position of the personal information in the screen memory 2 is shifted by 4 lines and stored (scrolled) in the window screen memory 8. . (4) As described above, the contents of the window screen memory 8 are updated, edited, and dot-expanded and displayed in the VRAM.

As a result of the above, when the window B is switched to the window A as shown in FIG.
The data display start position is scrolled downward by four lines and is displayed in the visible region from the first line, and it is not necessary to move the window position.

In the above embodiments, the case where the original screen is not scrolled has been described, but the operator may scroll as in the conventional case. In this case, based on the overlap amount and the first scroll amount from the origin by the operator, the second scroll amount at which the reference data (which is determined by the business process) is displayed in the visible region is calculated and the display is started. Change the position.

[0032]

As described above, according to the present invention, when parallel processing is performed in a plurality of windows, the data display start position is changed by switching windows and predetermined data that has disappeared due to overlapping is displayed in the visible region. Since the visual reference can be made, it is possible to reduce the troublesomeness of the operator's operation and the work processing time.
