Description

Description: TECHNICAL FIELD The present invention relates to a multi-window display device for displaying a plurality of windows.

[Conventional technology]

Conventionally, this type of multi-window display device has a base window, windows A, B, C as shown in FIG.
It has a multi-window management table for storing control information for each multi-window display, and has a window memory for storing text images displayed in windows A, B, and C, respectively. The text images stored in the window memory are in any order.

In the management tables of the windows A, B, and C, a pointer indicating the next window, a pointer indicating the previous window, a pointer indicating the base window, and the like are stored in addition to the display size and coordinates.

In this case, in the management table for each of the windows A, B, and C, control information for multi-window display independent for each window is stored, and there is no relevance between the display texts of the windows.

It should be noted that the base window is screen information serving as a base that exists on the screen, and a pointer and the like indicating the first window A are stored in the screen information table. In the management table of the first window A,
Since there is no previous window, null information is stored as a pointer to the previous window. Similarly, if the window C is the last, there is no next window,
The management table of the window C stores null information as a pointer indicating the next window.

When a multi-window management table having such an order is provided, the base window is displayed, and the texts of the windows B and C are superimposed and displayed so as to be hidden by the texts of the windows A and B, respectively. in this case,
Window A is an active window capable of both input control and output control, and windows B and C are windows capable of only output control. Also, for example, 2
When two texts are displayed in the windows A and B, each text is stored in the window memory so as to correspond to the windows A and B, so that each text is continuously displayed in the windows A and B as shown in FIG. Can also be displayed.

[Problems to be solved by the invention]

However, in the above-described conventional multi-window display device, the management table for each of the windows A, B, and C includes:
Regardless of the text displayed in each of the windows A, B, and C, control information for independent multi-window display is stored for each of the windows A, B, and C, and the texts are not related to each other. When displaying a text image that is continuous with the text while leaving the text displayed in a window, the operator intentionally writes the text in each window so that each display text is continuous on the CRT display screen. There is a problem that the operation has to be troublesome because it has to be generated and operated in the window memory.

Also, even if the operator generates text in the window memory so that each display text is continuous on the CRT display screen, if the display text in one window is changed, the texts are not related to each other. However, the continuity is lost and another text must be changed again, which complicates the operation.

Therefore, if the texts of a plurality of windows are continuous, the order is stored, and if the texts of the windows are rearranged and read in this order so as to be continuous on the display screen, the texts are continuously displayed on the display screen. Can be displayed.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to quickly rearrange windows and information having the continuity in accordance with a user's instruction to obtain an easy-to-view display when the information to be displayed has continuity.

Input via the keyboard control unit 12
U (central processing unit) 13 takes in.

The CPU 13 processes various control information by a microprogram stored in advance, reads the text of each window stored in the window memory 14, causes the window display control unit 15 to perform multi-window display, and displays the position of each window. , Size, priority, and text information are set in the continuity window management table 16.

Here, the window memory 14 stores texts displayed in windows A, B, and C of the display screen of the CRT 20, respectively, and the texts are stored in no particular order.

The continuity window management table 16 includes, in addition to the conventional multi-window management table as shown in FIG.
A group pointer indicating the first display window of the continuous text, a pointer indicating the next display window as control information of the window displaying the continuous text,
That is, text information is stored.

Therefore, as shown in FIG. 3, two consecutive texts (displays "1" and "2") are displayed continuously in windows A and B, and text displayed in window C (displays "3") is displayed. ) Indicates "1" in windows A and B.
If it does not continue to “2”, the continuity window management table 16 stores the base screen information existing on the screen and the pointer indicating the first window A in the base window as shown in FIG. A table, a group pointer indicating the first display window A of the continuous text, and a management table for each of the windows A, B, and C are stored.

Each of the management tables of the windows A, B, and C has its size and display coordinates, a pointer indicating the next window, a pointer indicating the previous window, a pointer indicating the base window, and a next text after the continuous text. (Text information) and the like indicating the display window are stored.

Since there is no previous window in the management table of the first window A, null information is stored as a pointer indicating the previous window, and the management table of the second window B has the following same text. Because there is no
Null as a pointer to the next display window
Since the information is stored, and the next window and the same text do not exist in the management table of the last window C, Null information is stored as a pointer indicating the next window and a pointer indicating the next display window, respectively. Is done.

When the CPU 13 specifies a plurality of display windows to the continuity window output control unit 17, the continuity window output control unit
17 reads each window control information from the continuity window management table 16, determines the group pointer,
When the window control information of the continuous text is read,
The text in the window is displayed in the window display control unit 15

When a discontinuous text is specified, the window display control unit 15 uses the window control information of the continuity window management table 16 to read out each text in the order stored in the window memory 14 for multi-window display. Of control information is generated.

On the other hand, when continuous text is specified, the window display control unit 15
The window memory 14
, And generates control information for multi-window display for reading out the texts stored in the.

If the window control information of the continuity window management table 16 is such that the windows A and B do not overlap and the window C is hidden by the windows A and B as shown in FIG. Is address information for reading all the texts of the windows A and B and for reading a part of the text of the window C which is not hidden by the windows A and B.

Therefore, all of the texts in the windows A and B and a part of the text in the window C are read out and transferred to the display memory 18 by the read address, and are transferred to the display control unit.
If the data is read continuously in units of frames according to 19,
As shown in the figure, the texts of the windows A and B are displayed on the CRT 20 so as to be continuous.

FIG. 6 is a flowchart for explaining the operation of the above embodiment.

When an instruction is fetched via the keyboard 11 in step S1, it is determined in step S2 whether the instruction is a display instruction or a window generation instruction. If the instruction is a display instruction, the process proceeds to step S3 and subsequent steps.

In step S3, the window n specified via the keyboard 11 is set as a display window, and the subsequent step S4
In, the text in the window memory 14 is read,
It is displayed in the display window n according to the window control information of the continuity window management table 16.

Next, in step S5, the next window n specified via the keyboard 11 is set as a display window,
In step S6, it is determined whether or not the windows specified via the keyboard 11 are all,
The text of all designated windows is read from the window memory 14 and the continuity window management table 16 is read.
Is displayed in the display window n according to the window control information.

In this case, if the text information indicating that the text is continuous is not set, the text in a preset order is displayed in each display window n, and the text information indicating that the text is continuous is set. , The text in the order of the text information is displayed in each display window n.

On the other hand, if it is determined in step S2 that the input command is a window generation command, the window control information to be subsequently input is set in the continuity window management table 16 in step S7.

Next, in step S8, when it is determined that the input instruction is a continuity window generation instruction, the process proceeds to step S9, and as shown in FIG. 4, a pointer indicating the head of the first text window is set as a group pointer, A pointer indicating the head of the second and subsequent windows of the same text is set as the display window of the previous window.

Therefore, when information of continuous text is set in steps S8 and S9, in steps S3 to S6,
The text of each window is displayed continuously on the screen.

〔The invention's effect〕

According to the present invention, the first display control information for displaying a plurality of windows and the information displayed in the windows in a display order according to a user operation, and the display contents have continuity. Second display control information for displaying in accordance with a specific display order is stored in advance, and the first display control information is stored in the first display control information.
