Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device, and particularly to a split screen display device that displays a plurality of windows simultaneously.

[Summary of the invention]

In a multi-window system, multiple windows are displayed on top of each other, so only a portion of the window other than the frontmost window is displayed. According to the present invention, a display screen is divided according to the number of windows, and a plurality of windows are displayed on one display screen.According to the present invention, a display device with good operability in a multi-window system is obtained. be able to.

[Prior Art] In personal computers and the like, multi-window display devices are often used that run multiple tasks at the same time, such as single-user multitasking, and switch display screens when necessary. This allows the user of the personal computer to simultaneously execute a plurality of related processes while switching screens.

In addition, even in one program, multiple processes such as editing and registration can be displayed in the menu, and the current status of each process can be managed on a display screen basis, simplifying the process. There are some things.

In a system that requires multiple display screens as described above, in order to display on one display device, one
Multi-window systems are widely used in which screens are treated as windows and each window is managed individually.

In a conventional multi-window system, a window menu is selected using a mouse.

For example, when the window menu on the display screen is displayed, move the mouse cursor so that it points to the "Generate" item on the menu. Press (click) the button switch that is displayed to specify generation. By pressing this button, the display of the "Generate" menu changes to a shaded display, and the display of the mouse cursor also changes. Then, a window corresponding to the generation will be displayed. A window is displayed by such an operation.

A window menu to be displayed is created, and if multiple menus are to be displayed, move the mouse cursor, specify the window menu in the same manner as described above, and press the button switch.

Conventionally, when using multiple windows, the position and size of the window to be displayed are repeatedly moved, enlarged and reduced, etc. by the window creation process called "generation" mentioned above. The placement of each window was considered so that they did not overlap on the display screen.

Similarly, for the window that has been created,
The windows were rearranged so that they did not overlap.

[Problem that the invention seeks to solve]

In such processes such as window generation and rearrangement, all of the information required therefor has been obtained through operator operations. Therefore, in the conventional multi-window display, it takes a lot of time to operate. In addition, even in systems that display and operate multiple windows, in order to display multiple windows at the same time without overlapping, it is necessary to decide in advance what kind of windows will be displayed at the same time, and to display the windows that should be displayed. It was not possible to satisfy all possible combinations, but it was difficult to create such a configuration.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks of the conventional art, it is an object of the present invention to provide a split-screen display device that displays a plurality of windows on a display screen without overlapping with a simple operation.

[Means for solving problems]

FIG. 1 is a diagram showing the principle configuration of the present invention. 1 is a display means for displaying a window, etc.; 2 is a first recording means for storing a plurality of window information; 3 is a first storage means;
Dividing means divides the display screen in accordance with a plurality of window information that has been divided into α, and numeral 4 denotes a second storage means that stores information to be displayed on the divided display screens.

[For production]

The dividing means 3 reads the plurality of window information stored in the first storage means and detects the number of windows. Then, the screen to be displayed by the display means is divided in accordance with the number of windows, the plurality of window information is assigned to the divided screens, and the window information is stored in the second storage means. Then, one screen data is created based on the window information stored in the second storage means and displayed on the display means 1.

〔Example〕

Hereinafter, the present invention will be explained in detail using the drawings.

(Created by Circuit) FIG. 2 is a circuit diagram of an embodiment of the present invention.

The mouse 5 is a simple coordinate input device. For example, when an operator slides the mouse 5 on a desk surface, data is sent to the mouse control device 6 in accordance with the amount of movement.
join. The mouse control device changes the position coordinates of the mouse cursor displayed on the display screen 7 using data corresponding to this movement amount, and adds the changed position data to the processor circuit 8.

The mouse 5 has a button switch 5, and when the button is pressed by the operator, switch information indicating that the button has been pressed is sent to the processor 8 via the mouse control device 6.

The processor 8 writes a cursor pattern to, for example, a graph ink display memory (not shown) based on the position information added from the mouse control device 6 described above, and displays the cursor pattern along with the display data stored in the display memory 10 via the display control device 9. Section 7 (CRT). As a result, the mouse cursor moves within the display screen in response to the movement of the cursor 5.

On the other hand, when the button switch 5-1 of the mouse 5 is pressed, the processor 8 records the current position of the mouse cursor.
,I! L. Detects which menu on the display screen is specified and executes processing corresponding to the specified menu. For example, when the menu item "screen division" is specified, the following fractional display processing is performed. A keyboard 12 is connected to the processor 8 via a keyboard control position 11, and key data from this keyboard can also be used to command menus, process windows, and input other data.

That is, in the embodiment of the present invention shown in FIG. 2, data can be input from the mouse 5 and the keyboard 12.

In the following, a description will be given of the normal display and split display operations using the mouse 5 and keyboard 12 in the split display process.

The window memory 12 stores window display data created by the operator's operations on the keyboard 12 and mouse 5, and the window management table 13 stores window information indicating the position at which the window display data is displayed and the front-back display relationship of windows. is stored.

The display data stored in the window memory 12 is data of a display screen image, and based on the window information stored in the window management table 13, for example, multi-window display as shown in FIG. 4(a) is performed. be done. The overlap control device 14 controls such display.

When the overlap control device q receives an overlap display instruction signal from the processor 8, it first refers to the window management table, divides the display screen for displaying each window, and determines which window to display in each divided area. Control Memuri 1 to display display information that instructs
Store in 5.

(Management Table) FIG. 3 (4) is an explanatory diagram showing the contents of the window management table. This table is provided for each window, and the width bpw (third
Figure (L・)), window height bpl+ (Figure 3 f
cl), the X coordinate bpx and Y coordinate bpy on the display screen of the upper left corner of the display window, and the size of the characters in the window C3'+7. e, pitch between lines pitch, next window pointer, i.e., first address of the backward window management table fp, +iii window pointer bρ, first subwindow management table pointer s w s 'p, last subwindow management Table pointer swap, yL window pointer p
Data title of arenL title bar, active title bar atbps and inactive title bar dtbρ are stored.

In the embodiment of the present invention, as shown in FIG. The pointer swsp of the management table of the first subwindow points to the first subwindow 8, and the pointer fp+ to the next window in subwindow A points to the top of the management table of subwindow B.Then, The pointer fp2 to the next window of subwindow B points to the top of the management table of subwindow C. Since subwindow C is the last, the pointer to the next window of subwindow C is stored as null (NULLi900v). This indicates that this sub-window C is the last.Furthermore, these management tables are connected from the rear by pointers bp3.bp2 from the last sub-window swap of the parent window to the previous windows in sequence. Note that null data is stored in the pointer bp+ to the frontmost window of subwindow A.The relationship of the subwindow with respect to the parent window is thus stored.

In most cases, a parent window represents, for example, one screen, but in cases where additional windows are provided within a plurality of windows, the parent windows are used to establish a relationship between the parent windows. Note that at this time, a higher level window management table is provided.

In addition, in sub-windows A, B, and C, there is a pointer to the parent window as shown in Figure 3 (al).
is provided, and its pointer parent+ +p
arent2. From parent3, it is known which parent window this subwindow belongs to.

(Overlapping display) Each area in the overlapping window display is divided using the management table for each sub-window A, B, and C described above, and a display control memo is used to indicate which part of which window is displayed in that area. Stored in IJ15. The stored data is then read out by the window display device 16.

In order to store the area in the display memory 10 at a position corresponding to each area, the window display device reads out the area from the window memory 12 and uses a focus mover (Bit Move).
r) The data is moved and stored in the display memory 10 in step 17. The focus mover 17 displays the read data in the memory 1.
This is a circuit that instructs which position within 0 to store.
For example, it is a circuit that converts the storage address of the display memory 10 based on information given by the screen's X coordinate bpx and the screen's Y coordinate bpy. That is, the contents of the bit/node data corresponding to each display dot do not change, but the address where the data is stored changes by the bit mover 17.

(Split Display) The above-described operation produces the overlapping display shown in FIG. 4(a). On the other hand, when the screen splitting process is executed (
Figure 4 (b)
(Move it to the position shown in and press button switch 5-1)
, the processor 8 executes the split display flowchart shown in FIG. First, the current parent window is detected, and processing STI for calculating the number of subwindows related to the parent window is executed.

FIG. 6 is a flowchart for determining the number of windows in an embodiment of the present invention. When this process is executed, first,
A process S1 is executed in which the register C0UNT in the processor 8 is set to 1. Similarly, the start address of the parent management table is stored in the pointer P in the processor 8 (S2).

Next, pointer 5w5 that points to the first subwindow in the table pointed to by pointer P, that is, the parent table.
It is determined whether the content of p is null (NULL) at step S3.

In this determination S3, if the data is null (YES), since it is only the parent window, the value of the register C0UNT is set to O by a process not shown, and then the process ends. - Also, if the data is not null (NO), a subwindow exists, so pointer 5 points to the first subwindow of the management table pointed to by pointer P.
The contents of w5p are stored in pointer P S4. Through this process, the start address of the management table for subwindow A is stored in the pointer.

Next, it is determined in step S5 whether the pointer fp to the next window indicated by the table address newly stored in the pointer P is null data.

When the data is not null (NO), the register C0UNT
A process S6 is performed in which the content of is incremented (fl) and a pointer fp to the next window indicated by t'F1 is stored in the table address stored in the pointer P. Then, the above-described determination process S5 is performed again, and the process S5 is repeated until the pointer fp to the next window becomes null data.
6 and the determination process S5 are repeated. In the final subwindow management table, the pointer to the next window mentioned above is
Since p is null data (YES), this process ends.

When this process is completed, the value of the register C0UNTO of the processor 8 becomes the number of sub-windows. For example, in the configuration shown in Figure 3 (bl), the register C0U
The NTO value will be 039.

Since the number of sub-windows to be displayed is determined by the above-described process STI, next a process ST2 for determining a division pattern is executed.

In the embodiment of the present invention, the display screen is divided into two vertically, and the two divided regions are further divided horizontally.

First, the number of subwindows to be displayed, that is, the register C0UNTO value Z, is divided by 2. This quotient is the number of divisions in the upper row
shall be. That is, it is expressed as: X=Z%2...(]). Note that in formula (1), % is an integer value of the quotient when Z is divided by 2. The number of divisions in the lower row is the value obtained by adding the correction value Y to the number of divisions X in the upper row.

Note that the correction value Y is a value that is 1 when the count value Z is an odd number and O when the count value Z is an even number. That is, Y=Z-2・X
...It is expressed as (2).

FIGS. 7(a) to 7(f) are diagrams for explaining the order of division and window display when the number of subwindows, that is, the value of Z is 2 to 7.

When there are two windows, windows W+ and W2 are allocated to the top and bottom (FIG. 7(a)). 31 [1i1, window WI is on the upper side and window W2 is on the lower side. W3 is assigned (FIG. 7(b)). Similarly, in the case of 4111i1, there are windows W + and W2 in the upper row, and windows W y and W y in the lower row.
W a (Figure 7(C)). When there are 5 windows, there is a window W + + W 2 in the upper row and a window W3 in the lower row. W
a, W! 1 (Figure 7(d)). When there are 6 windows, there is a window W + r W 21 W 3 in the upper row and a window W4 in the lower row. W5°W6 (Fig. 7(e)). When there are seven windows, windows W I''-W3 are assigned to the upper row, and windows W4 to W? (FIG. 7(f)) are assigned to the lower row.

Process ST corresponding to the value of the number of windows Z as described above.
In step 2, the display screen is divided and assigned to each window.

After this process ST2, a process ST3 is executed in which the coordinates X and Y of each allocated and divided area are determined and stored in the respective management tables. As a result, each management table stores the value assigned to the corresponding area. Of course, at this time, the dimensions in the vertical and horizontal directions, that is, the window width bpw and the window height bph are also calculated and stored in the management table.

When the above processing is completed, the processor 8 causes the overlap control device 14 to start executing display processing.

In the overlapping display described above, the area where each window overlaps is detected, the area is divided, and the overlapping display is performed. However, after the process shown in Figure 5 described above is completed, the respective active windows do not overlap. Therefore, the overlamp control device 14 is simply divided and stores display control data in the display control memory 15 in area units. When this is completed, the position at which the contents of the window memory 12 are stored in the display memory is controlled by the bit mover 17 under the control of the window display device 16 as in the case of overlapping display, and the contents are stored in the display memory.

As a result, the divided images are displayed on the display screen 7 via the display control device V19 as shown in FIG. 4(C). Note that since the active window is always indicated by the parent window first, window W! in FIG. 7 (11-(f)) corresponds to this.

〔Effect of the invention〕

As described above, the present invention divides one screen when displaying multiple windows, and allocates and displays each window to the divided areas.According to the present invention, multiple windows can be displayed with a simple masterpiece. It is possible to obtain a screen split display device that displays images on a display screen without overlapping.
