BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-window display device which displays a plurality of windows.

[0002]

2. Description of the Related Art In personal computers and the like,
2. Description of the Related Art A multi-window display device that drives a plurality of tasks at the same time, such as a single-user multi-task, or the like, and switches the display screen when necessary, is widely used. As a result, the user of the personal computer can simultaneously execute a plurality of related processes while switching the screens.

Further, even with one program, a plurality of processes such as editing and registration are displayed in a menu, and the current state of each process is managed by each display screen, and the process is performed. Some have been simplified.

In a system requiring a plurality of display screens as described above, in order to display on one display device, a multi-window system is often used in which one screen is used as a window and is managed in window units. ing.

In the conventional multi-window system, a window menu is selected by using a mouse or the like. For example, when the window menu in the display screen is displayed, the mouse is moved so that the cursor points to the target item of the window menu. Then, the button switch provided on the mouse is pressed (clicked) to display the window corresponding to the target item. The window is displayed by such an operation.

The above-mentioned window is not limited to a single window, and when there are a plurality of target processings, it is possible to display them as if they were superimposed. Also, there is one in which one screen is divided and each window is displayed in a divided area. In addition, a system that considers the layout so that each window does not overlap on the display screen by repeatedly performing window moving processing, scaling processing, etc. for the position and size of the window to be displayed afterwards by window creation processing etc. is there.

[0007]

By the way, in the conventional multi-window system, when the window is closed and the work is finished, the displayed window is erased. Therefore, even if the work is once finished and the work in the same window is restarted, the operator must perform the window display operation again. For this reason, there is a drawback that it takes a lot of operation time to display the window and the work efficiency is poor. An object of the present invention is to register a displayed window and automatically display the registered window at the time of starting operation so that an operation required for window display can be eliminated and an operation time can be shortened. Is.

The present invention will be described in detail below with reference to the drawings.

{Circuit Operation} FIG. 1 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 holds the mouse 5 and slides it on the desk surface, data is added to the mouse control device 6 in accordance with the amount of movement. The mouse control device 6 displays the position coordinates of the mouse cursor displayed on the display screen 7,
A change is made using the data corresponding to this movement amount, and the changed position data is added to the processor (CPU) 8.

The mouse 5 has a button switch 5-1.
When a button is pressed by the operator, switch information indicating that the button has been pressed is added to the processor 8 via the mouse controller 6.

The processor 8 is the mouse controller 6 described above.
A cursor pattern is written in, for example, a graphic display memory (not shown) based on the additional position information, and is displayed on the display screen 7 (CRT) together with the display data stored in the display memory 10 via the display control device 9. As a result, the mouse cursor moves in 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 recognizes the current position of the mouse cursor, detects which menu on the display screen is instructed, and receives the instruction. Execute the process corresponding to the menu. For example, when the item “generation” in the menu is instructed, window generation processing is performed. A keyboard 21 is connected to the processor 8 via a keyboard control device 11.
With the key data from 1, it is possible to instruct a menu, process a window, and input other data. That is, in the embodiment of the present invention shown in FIG. 1, data can be input from the mouse 5 and the keyboard 21.

In the following, overlapping display and operation according to an instruction of the split display processing from the mouse 5 or the keyboard 21 will be described.

The window memory 12 stores the window display data created by the operation of the operator of the keyboard 21 and the mouse 5 described above, and the window management table 13 indicates the position where the window display data is displayed and the front-back display relationship of the windows. The window information to represent is stored.

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

When the overlap display instruction signal is applied from the processor 8, the overlap control device 14 first refers to the window management table 13 to divide the display screen 7 in the display of each window, and which one of the divided regions is displayed. Display information indicating whether to display a window is stored in the display control memory 15.

FIG. 2 shows that when the number of windows to be displayed is one,
It is a figure showing each divided area at the time of two. In the case of one, it is divided into areas A1 to F1 and windows to be displayed and other displays are assigned to the respective rectangular areas.

The same applies to the case of two areas, and the area A
Assign windows and other displays to be displayed in the rectangular area of 2 to L2. In the embodiment of the present invention, those areas are not shown, but are managed in units of one rectangle, and the area is limited by the upper left point of the rectangle and the lengths in the horizontal and vertical directions.

{Management Table} FIG. 3 is an explanatory diagram showing the contents of the window management table 13. This table is provided for each window, and the corresponding window width bpw (FIG. 5) and window height bph

ent, title bar data title, active title bar atbp, inactive title bar dt
bp is stored.

In the embodiment of the present invention, as shown in FIG. 4, for a main window (parent window), a plurality of sub-windows can be provided in the window, and the sub-window in the parent window table can be provided. The first subwindow A is pointed to by the pointer swsp of the management table of the first subwindow of, and the beginning of the management table of subwindow B is pointed to by the pointer fp1 of the next window in subwindow A.
Then, the head of the management table of the sub window C is designated by the pointer fp2 to the next window of the sub window B. Since the sub-window C is the final one, null (NULL; "00") is stored in the pointer to the next window of this sub-window C, indicating that this sub-window C is the final one. On the contrary, these management tables correlate the connections from the rear by pointers bp3 and bp2 from the last subwindow swep of the parent window to the previous window in sequence. Null data is stored in the pointer bp1 to the frontmost window of the sub-window A. These store the relationship of the subwindow to the parent window.

In most cases, the parent window represents, for example, one screen. However, when a plurality of windows are further provided, the parent windows similarly relate the parent windows. At this time, a higher window management table 13 is provided.

Further, in the sub-windows A, B and C, as shown in FIG.
t is provided, and its pointers parent1, p
From parent2 and parent3, it is possible to know which parent window this subwindow belongs to.

{Overlap display} Using the management table of each of the sub-windows A, B and C described above, each area in the overlap window display is divided, and which part of which window is displayed in that area. It is stored in the display control memory 15. And window display device 1
The stored data is retrieved by means of 6. Since the data is stored in the position of the display memory 10 corresponding to each area, the window display device 16 reads the area from the window memory 12 and also performs bit move (Bit Move).
r) Move processing is performed in 17 and stored in the display memory 10. The bit mover 17 is a circuit for instructing which position in the display memory 10 to store the read data. For example, the bit mover 17 is based on the information given by the X coordinate bpx of the screen and the Y coordinate bpy of the screen. Is a circuit for converting the storage address of. That is, there is no change in the content of the bit data corresponding to each display dot, and the address at which the data is stored changes with this bit mover 17.

[Registration of window information] By the above operation, display processing is performed in window units. The present invention relates to the window display at the time of turning on the power in the display processing described above.

FIG. 6 is a flowchart of the operation processing of the window manager program that operates when the power is turned on. For example, after the power is turned on, the window manager program is first executed (started). Then, first, a determination process S1 of whether or not the window information file exists in the external storage device 18 is executed. In this determination process S1, if the window information file does not exist in the external storage device 18 (N), the initial screen display process S2 is performed. FIG. 7 is a display example diagram in which the window menu WM is displayed by the execution of the initial screen display processing S2. This window menu is, for example, a menu item such as window creation. Pressing the key corresponding to this menu,
Starts the next execution according to the instruction from the mouse. That is, after executing the process S2, the process waits for the operation of the operator, and when input data is added, the process corresponding to the operation is executed.
