Description

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

[Summary of the invention]

In systems that display multiple windows at the same time,
In order to stop displaying multiple windows and display them again, you must perform operations to display the windows one after another on the same screen. The present invention stores the state when a plurality of windows are displayed simultaneously in a storage means, and when displaying them again, displays the plurality of windows from the state stored in the storage means, and replays the multi-window. The display is simplified to M.

[Traditional technique]

With the development of microprocessors, various complex processes in word processors, screen editors, etc.
Now you can do it on IT. For example, in screen editors, etc., even if there is a large amount of data to be edited,
Display multiple screens (windows) in an overlapping manner,
It is clear which page the operator is currently editing. This is applied not only to screen editors but also to word processors, other hierarchical programs, input processing, and the like. Traditionally, windows like the one mentioned above are
A plurality of settings are made by the operator's operation, and an overlapping display as described above is made.

Generally, when displaying a multi-window, when the display is no longer needed or when the display is changed to display other items, the display of multiple windows that have been set is deleted one by one.

For example, a single window is paused by a single operation using a mouse, keyboard, etc., and all windows are paused by doing this multiple times. Furthermore, when resuming a single window that has been paused, the user must operate the mouse, keyboard, etc. to display it again.

(Problem to be solved by the invention) As mentioned above, when setting multiple windows and performing some processing by operating the mouse, keyboard, etc.
When executing interrupt processing or other processing, perform the processing operation to suspend the number of windows that you set, and after the processing is finished, if you want to display or resume again, use the operation that was originally set. had to be repeated again.

Furthermore, when inputting a catalog in a hierarchical structure in a multi-window, it is necessary to respond to the catalog input each time in order to always perform the desired processing. In this way, for example, even though a small amount of data is manually processed, a large amount of window setting processing must be performed, resulting in wasted time.

The present invention solves the above-mentioned problems, and its purpose is to provide a multi-window display device that can resume display (batch pause) multiple windows with a single designation process and is easy to operate. be.

〔Example〕

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

FIG. 2 is a circuit diagram of an embodiment of the present invention.

The mouse 5 is a simple coordinate human-powered device. For example, when an operator slides the mouse 5 on a desk surface, data corresponding to the amount of movement is sent to the mouse control device 6'.
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 applies 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, the mouse control bag r! receives information indicating that the button has been pressed. 16 to the processor 8.

The processor 8 inputs a cursor pattern into, for example, a graphic display memory (not shown) based on the positional information provided by the mouse control device 6, and displays the display data stored in the display memory lO' via the display control device 9. Along with the display section? (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 (
Q, it detects which menu on the display screen is designated, and executes the process corresponding to the designated menu. For example, when the menu item "screen division" is specified, the following fractional display processing is performed.

A keyboard 21 is connected to the processor 8 via a keyboard control position 11, and key data from this keyboard can also be used to instruct 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 21.

In the following, superimposed display based on instructions for split display processing from the mouse 5 or keyboard 12 will be explained first.

The window memory 12 stores window display data created by the operator's operations on the keyboard 21 and mouse 5, and the window management table 13 stores window information indicating the position where the window display data is displayed and the front and back display relationship of windows. is stored.

The display data stored in the window memory 12 is data of a display screen image, and is displayed based on the window information stored in the window management table 13. The overlamp control device 14 controls such a display.

When the overlamp display instruction signal is applied from the processor 8, the overlamp control device 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. The display information to be instructed is stored in the display control memory 15.

FIG. 3(a) 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 (C)), window height bph (Figure 3 (C))
, the X coordinate b of the upper left corner of the display window on the display screen
pw and Y coordinate bpy, next window pointer, i.e. the starting address fp of the backward window management table, previous window pointer bp, first subwindow management table pointer 5w5p, last subwindow management table pointer swap, parent window The pointer parent and paper feed flag slpflag are stored.

In the embodiment of the present invention, as shown in FIG. 3(b), a plurality of sub-windows A to C can be provided within the main window (parent window OW). Pointer swa to the management table of the first subwindow in the parent window table
The first subwindow A is pointed to by p, and the pointer rpl to the next window within subwindow A
The beginning of the management table of subwindow B is indicated by . Then, the pointer [1)z to the next window of subwindow B points to the beginning of the management table of subwindow C. Note that since sub-window C is the last, the pointer to the next window of this sub-window C is stored as null (NILL, "OO"), indicating that this sub-window C is the last. Conversely, bp:I is a pointer from the last subwindow swap of the parent window to the previous window sequentially.

related by bpz. Note that null data is stored in the pointer bp1 to the frontmost window of the subwindow A. These store the relationship of the subwindow to the parent window.

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 the sub-windows A, B, and C, a pointer "parent" to the parent window is provided as shown in FIG. 3 (18), and the pointer "parent+
From rent4 and parenj3, it is known which parent window this subwindow belongs to.

Using the management table for each of the sub-windows A, B, and C described above, the overlamp control unit 14 divides each area in the overlapping window display, and displays which part of which window is displayed in that area. It is stored in the memory 15.

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 the area from the window memory 12, moves the area using a bit mover 17, and stores the area in the display memory 10. The focus mover 17 is a circuit that controls where read data is stored in the display memory 10. For example, the focus mover 17 controls the display memory 10 based on information given by the X coordinate bpx of the screen and the Y coordinate bpy of the screen.
This is a circuit that converts it into a storage address. In other words, there is no change in the contents of the bit data corresponding to each display dot, and the address where the data is stored is the focus mover 17.
It changes.

Through the above operations, display data in which, for example, three windows are superimposed is stored in the display memory. This display data is continuously outputted by the display control device 9 and displayed on the display section (
Displayed on CRT) 7.

The display operation described above is performed every time an individual window is registered using the mouse 5 or the like.

On the other hand, in the embodiment of the present invention, a batch suspension process (suspension of display) for suspending the display of multiple windows currently displayed by keyboard operation or mouse cursor instruction from the window control menu on the display screen; Perform batch display restart processing to redisplay the paused display. The processor 8 controls this batch suspension process and batch display restart process.

FIG. 4 is a display example of batch suspension, and FIG. 5 is a flowchart of batch suspension processing. For example, when the mouse 5 is operated to move the mouse cursor MC to the window control menu WM and the button switch 5-1 of the mouse 5 is pressed, the processor 8 moves the mouse cursor MC as described above. to detect which menu on the display screen has been designated. Then, the instructed batch suspension process (FIG. 5) is executed (START). First, the contents of the pointer 5w5p stored in the parent window OW are stored in the work register WP (S). Note that the work register WP is included in the processor. Then, it is determined whether the contents of the work register wp are NILL, that is, 900g (S2). When this discrimination process is executed from process S1 (described later, process S5
Execute this process even after ) is NILL (
In Y), only the parent window is displayed on the current display screen, so one screen is made up of one window, and there is a pause lag to the subwindow 5, which will be described later.
The lpf lag process is not executed, but the basic window, that is, the pace window display process S3 is executed, and the process is ended (END).

On the other hand, when the contents of the work register WP are not NILL (N), the currently displayed parent window OW, that is, the subwindow is displayed within one screen, so the next command is given by the work register WP. Execute processing S4 to store °IW in the suspension flag Slpflag of the subwindow management table. The pause flag 5lpf lag in the subwindow management table is a flag that indicates that the corresponding subwindow is being displayed until just before it is paused, and when this flag is 19, the corresponding subwindow is displayed during the batch display restart process described later. .

In the embodiment of the present invention, the subwindow management table pointer fp mentioned above points to the next subwindow management table, so after the above process S4, the next subwindow management table pointed to by the work register WP A process S5 is performed to store the subwindow management table pointer "p" in the work register wp.

Next, the above-described determination process S2 is executed to determine whether the work register WP is NILL. Then, when the value is not NILL, the above-mentioned processes S4, S5, and S6 are performed.
Repeat sequentially. As a result of this sequential repetition process, all of the suspension flags Slpflag in the subwindow management table corresponding to the currently displayed subwindow are set to 9.
It becomes 1g.

When NILL is detected by the discrimination process S2, there is no next subwindow, so next, the base window S3 is selected as in the case where only the parent window exists.
Execute and end the process. FIG. 4(b) is an example of a display when the batch suspension process is executed, and the subsequent process, such as the display process in response to an interrupt, is displayed.

FIG. 6 is a display example diagram for restarting batch display, and FIG. 7 is a flowchart of batch display processing. Interrupt processing etc. are completed,
When the window control menu WM is displayed and the operator returns to the state immediately before the above-mentioned batch pause, the operator:
The mouse 5 is operated to move the mouse cursor MC to the position for restarting batch display, and the button switch 5-1 is pressed. Upon this depression, the processor 8 detects the same position as described above and executes (START) the pattern display restart process. First, in order to detect a parent window that has been paused, the parent window's pause flag Slpflag is set 917) and the contents of the pointer 5w5p of the parent window are stored in the work register WP (S6). Then, the contents of the work register are NI
It is determined whether it is LL, that is, 9009. This process S
If this discrimination process is executed from 6 (described later, process S
(This process is executed even after IO) If it is NILL (Y), only the parent window is displayed on the display screen before suspending, so as mentioned above, the area for one screen is - It is in the window state, and the process of displaying only the parent window, that is, the process of displaying all windows S8, is executed without executing the process of resetting the sleep flag Slpflag for the subwindow, which will be described later, and the process ends (END
). On the other hand, when the contents of the work register WP are not NILL (N), the subwindow is displayed on the currently paused parent window OW, that is, the display screen before the batch pause, so next, the work register WP is used to specify Pause flag Slpfla of the subwindow management table
Processing S9 is executed to reset g, that is, to store 909. Then, processing SIO is performed to store the management table pointer fp of the subwindow next to the subwindow indicated by the work register WP in the work register wp. Similar to the batch suspension process, next, a determination process S7 is executed to determine whether the work register WP is N I' L L. If the value is not NILL, the above-described processes S9, S10, and S7 are repeated in sequence. As a result of this repeated processing, the suspension flag of the subwindow that has been suspended is reset, that is, becomes WOW.

During this repetition, when NILL is detected by the determination process S7, there is no next subwindow, so the reset process of the flag Slpflag is finished,
All window display processing S8 is executed. The all-window display process S8 sequentially detects the next sub-window from the management table of the parent window that was inactive, and the next sub-window from the management table of that sub-window, and displays a series of sub-windows. This display is performed by the overlap control device 14 according to instructions from the processor shown in FIG.

As described above using the embodiment of the present invention, each management table for the parent window and subwindows also stores routine numbers and other information for each process for the window, and it is possible to restart the display at once. After that, the state will be the same as before the pause.

Furthermore, by storing the window management table in an auxiliary memory or the like, the same plurality of windows can be displayed and the processing can be restarted even if the power is turned off and then turned on again.

〔Effect of the invention〕

As described above, the present invention enables, for example, when the display etc. is temporarily paused by executing the batch pause process and other processes are performed, the display is returned to the state before the pause by executing the batch restart process. Therefore, according to the present invention, although it is a multi-window system, a plurality of window displays can be paused in one designation process, and a multi-window display device with excellent operability can be obtained.
