Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display control device for displaying a parent window having a preset window display size on a display screen.

(Prior art)

With the development of microprocessors, various complicated processes in a word processor, a screen editor, and the like can be easily performed. For example, in a screen editor or the like, even if there is much data to be edited, a plurality of screens (windows) are displayed in an overlapping manner to clarify which page the operator is currently editing. This is applied not only to a screen editor but also to a word processor, other programs having a hierarchical structure, input processing, and the like. Conventionally, a plurality of windows as described above are set by the operation of the operator, and the overlap display is performed as described above.

Generally, in a multi-window display, when it is no longer necessary to display the display or when the display is changed to display other items, the display of a plurality of set windows is deleted one by one in units of windows. For example, one window is paused by one operation using a mouse, a keyboard, or the like, and this operation is performed a plurality of times to suspend all the windows. Also, when resuming one paused window, a mouse, a keyboard or the like is similarly operated to redisplay.

[Problems to be solved by the invention]

As described above, when a plurality of windows are set by operating the mouse, the keyboard, and the like, and an interrupt process or another process is performed while performing some process, a pause process operation for the set number of windows is performed. Further, after the processing is completed, when the display is to be resumed, that is, when the display is to be restarted, the operation set at the first time has to be repeated.

Also, in a catalog input having a hierarchical structure in a multi-window, it is necessary to always respond to the catalog input in order to always perform a desired process. As described above, for example, despite input of a small amount of data, many window setting processes must be performed, and there is a problem in that there is wasted time.

An object of the present invention is to realize temporary display erasure for a main window and a plurality of subwindows belonging to the main window, and resumption display by a simple instruction operation.

[Means for solving the problem]

 The means of the present invention are as follows.

In a window display control device for displaying a main window having a predetermined window display size on a display screen, the main window is displayed with a display area size according to the window display size, and a plurality of windows belonging to the main window are displayed. When the display of the sub-windows is set, the sub-windows are overlapped in the display area of the main window in the order according to the display order so that the sub-windows belong to the main window. Window display control means for displaying in the displayed state, and a window display pause instruction menu item is displayed on the display screen, and when the window display pause instruction menu item is instructed to be selected, the main window is temporarily stopped. And hide it from its main window. Erasing display means for erasing and displaying the main window and the subwindows from the display screen by temporarily hiding all of the subwindows, and a menu item for instructing window display resumption on the display screen. Is displayed, and when the instruction menu item for restarting the window display is selected and displayed, the main window is restarted and displayed in the display area size immediately before the non-display, and the sub windows belonging to the main window are displayed as Resuming display means for performing resuming display so as to overlap in a display state immediately before the non-display in the main window.

[Action]

 The operation of the means of the present invention is as follows.

When a main window whose window display size is set in advance is displayed with a display area size according to the window display size and display of a plurality of sub-windows belonging to the main window is set, The sub-windows are displayed in the display area of the main window in an overlapping display order in accordance with the display order so that the sub-windows belong to the main window. Then, an instruction menu item for suspending window display is displayed, and when the instruction menu item for suspending window display is instructed to be selected, the main window is temporarily hidden and the above-mentioned main window belongs to the main window. All the sub-windows are temporarily hidden, and the main window and the respective sub-windows are erased and displayed from the display screen.
Thereafter, when an instruction menu item for restarting the window display displayed on the display screen is selected and instructed, the main window is restarted and displayed in the display area size immediately before the non-display, and belongs to the main window. The sub-windows are restarted and displayed so as to overlap in the display state immediately before the non-display in the window.

〔Example〕

 Hereinafter, the present invention will be described in detail with reference to the drawings.

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 surface of the desk with the mouse 5, data is added to the mouse control device 6 in accordance with the amount of movement. The mouse control device changes the position coordinates of the mouse cursor displayed on the display screen 7 using the data corresponding to the movement amount, and adds the changed position data to the processor circuit 8.

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

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

On the other hand, when the button switch 5-1 of the mouse 5 is depressed, the processor 8 stores the current position of the mouse cursor, detects which menu on the display screen is being instructed, and displays the menu that has been instructed. Execute the corresponding process. For example, when an item "screen division" in the menu is designated, the following fraction display processing is performed. Although the keyboard 21 is connected to the processor 8 via the keyboard control position 11, menu data, window processing, and other data can also be input by using key data from the keyboard. 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, first, the overlap display according to the instruction of the divided display processing from the mouse 5 or the keyboard 12 will be described.

The window memory 12 stores window display data created by the above-described operation of the keyboard 21 and the mouse 5 by the operator. The window management table 13 stores window information indicating the position at which the window display data is displayed and the relationship between the front and rear display of the window. 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 overlap control device 14 controls such display.

When the overlap display instruction signal is applied from the processor 8, the overlap control device first refers to the window management table to divide the display screen in displaying each window, and determines which window is to be displayed in each of the divided areas. The display information to be instructed is stored in the display control memory 15.

FIG. 3A is an explanatory diagram showing the contents of the window management table. This table is provided for each window. The width bpw of the corresponding window (FIG. 3C), the height bph of the window (FIG. 3C), and the display screen at the upper left corner of the display window X coordinates bpw and Y above
Coordinates bpy, pointer of next window, ie, start address fp of rear window management table, pointer bp of previous window, pointer swsp of management table of first subwindow, pointer swep of management table of last subwindow, parent of parent window, parent , Pause flag s
lpflag is stored.

In the embodiment of the present invention, as shown in FIG. 3 (b), for a main window (parent window OW): a plurality of sub-windows A to C can be provided in the window, 1st sub-window a is instructed by the pointer swsp the first sub-window management table in the parent window table, the head is indicated in the management table of the sub-window B by a pointer fp ₁ to the next window in the sub-window a . Then, the head of the management table of the sub-window C is indicated by the pointer fp ₂ to the next window subwindow B. Since the subwindow C is final, a null (NILL; 00) is stored in the pointer to the window of the subwindow C, indicating that the subwindow C is final. On the other hand, in these management tables, the connection from the rear is related by pointers bp ₃ and bp ₂ from the last sub-window swep of the parent window to the previous window sequentially. In addition,
Pointer bp ₁ to the previous window of subwindow A
Stores null data. With these, the relationship between the subwindow and the parent window is stored.

The parent window almost represents, for example, one screen. However, when a window is provided in a plurality of windows, the parent windows are similarly related to each other by the parent window. At this time, a higher-level window management table is provided.

Further, as shown in FIG. 3A, a pointer parent to the parent window is provided in the sub-windows A, B, and C. From the pointers parent ₁ , parent ₂ , and parent ₃ ,
You can see which parent window this subwindow belongs to.

Using the management table of each of the sub-windows A, B, and C described above, the overlap control unit 14 divides each area in the overlapping window display, and controls which part of which window is displayed in that area. Memory 15
Is stored in And by the window display device 16,
The stored data is read. In order to store the data in the display memory 10 corresponding to each area, the window display device reads the area from the window memory 12 and moves the area by the bit mover (Bit Mover) 17 to display the area.
To be stored. The bit mover 17 is a circuit that controls where the read data is stored in the display memory 10. For example, the bit mover 17 is based on information given by the X coordinate bpx of the screen and the Y coordinate bpy of the screen. Is a circuit for converting the stored address into a storage address. That is, there is no change in the content of the bit data corresponding to each display dot, and the address where the data is stored is changed by the bit mover 17.

By the above operation, display data in which, for example, three windows are overlapped is stored in the display memory. The display data is read out by the display control device 9 and displayed on the display unit (CRT) 7.

The above-described display operation is performed each time an individual window is registered in the mask 5 or the like.

On the other hand, in the embodiment of the present invention, collective pause processing (pause of display) for suspending the display of a plurality of windows currently displayed by operating a keyboard or instructing a mouse cursor in a window control menu of a display screen; A batch display restart process for redisplaying the paused display is performed. The processor 8 controls the batch suspension process and the batch display restart process.

FIG. 4 is a display example of the collective suspension, and FIG. 5 is a flowchart of the collective suspension processing. For example, when the mouse cursor MC is moved to the position of the window control menu WM by operating the mouse 5 and the button switch 5-1 of the mouse 5 is pressed as shown in FIG. Is stored to detect which menu on the display screen has been designated. Then, the instructed batch suspension processing (FIG. 5) is executed (START). First, the contents of the pointer swsp stored in the parent window OW are stored in the work register WP (S1). Note that the work register WP is provided in the processor. Then, it is determined whether the content of the work register WP is NILL, that is, 00, at S2. When this discrimination processing is executed from the processing S1 (described later, this processing is also executed after the processing S5), if the result is NILL (Y), only the parent window is displayed on the current display screen. In this state, the area for one screen is regarded as one window, and the processing of the sleep flag slpflag for the subwindow described later is not executed.
Is executed, and the process ends (END). On the other hand, when the contents of the work register WP are not NILL (N), since the currently displayed parent window OW, that is, the sub-window is displayed in one screen, the next operation is designated by the work register WP. Pause flag Sl for subwindow management table
A process S4 of storing 1 in pflag is executed. The suspension flag Slpflag in the subwindow management table is a flag indicating that the corresponding subwindow is displayed until immediately before the suspension, and when this flag is 1, the corresponding subwindow is displayed at the time of collective display restart processing described later.

In the embodiment of the present invention, since the management table of the next sub-window is indicated by the pointer fp of the above-described sub-window management table, the above-described processing S4
After this, processing for storing the management table pointer fp of the subwindow next to the subwindow specified by the work register WP in the work register WP is performed.

Next, the above-described determination processing S2 is executed, and the work register
It is determined whether WP is NILL. If the value is not NILL, the above-described processes S4, S5, and S6 are sequentially repeated. As a result of this sequential repetition processing, all the pause flags Slpflag of the subwindow management table corresponding to the subwindow currently displayed become “1”. Discrimination processing S
When NILL is detected by 2, there is no subsequent sub-window, so the base window S3 is executed next and the process ends (END), as in the case where only the parent window exists. FIG. 4 (b) shows a display example when the batch suspension processing is executed, and the subsequent processing, such as the display processing corresponding to the interruption, is displayed.

FIG. 6 is a display example of restart of batch display, and FIG. 7 is a flowchart of batch display processing. When the interrupt processing or the like is completed, the window control menu WM is displayed, and when the operation returns to the state immediately before the above-described batch pause, the operator operates the mouse 5 to move the mouse cursor MC to the position for restarting the batch display. Press the button switch 5-1.
With this depression, the processor 8 detects the same position as described above, and executes the batch display restart processing (START).
First, the suspended parent window is detected (the suspension flag Slpflag of the parent window is 1), and the contents of the parent window pointer swsp are stored in the work register WP S6. Then, it is determined whether the content of the work register is NILL, that is, 00. When this discrimination process is performed from this process S6 (this process is also performed after the process S10, which will be described later), and if the result is NILL (Y), only the parent window is displayed on the display screen before pausing. Since it is displayed, the area corresponding to one screen is set as one window as described above, and the processing of resetting the sleep flag Slpflag to the sub-window described below is not executed, but the processing of displaying only the parent window, that is, the processing of all windows The display process S8 is executed, and the process ends (END). On the other hand, the content of the work register WP is NILL
Otherwise (N), the currently executing parent window OW
That is, since the subwindow was displayed on the display screen before the batch suspension, next, processing S9 for resetting the suspension flag Slpflag of the subwindow management table designated by the work register WP, that is, storing 0, is executed.
Then, a process S10 of storing the management table pointer fp of the subwindow next to the subwindow indicated by the work register WP in the work register WP is performed. Similarly to the batch suspension processing, next, a determination processing S7 is executed to determine whether the work register WP is NILL. If the value is not NILL, the above-described processes S9, S10, and S7 are sequentially repeated. The pause flag of the subwindow which has been paused by this repetition processing is reset, that is, to 0.
When NILL is detected by the discriminating process S7 during this repetition, there is no subsequent subwindow, so
The reset processing of the flag Slpflag ends, and the all-window display processing S8 is executed. The all-window display processing S8 sequentially detects the next subwindow from the paused parent window management table and the next subwindow from the subwindow management table, and displays a series of subwindows. This display is made by the execution of the overlap control device 14 according to the instruction of the processor in FIG.

As described above with reference to the embodiment of the present invention, the management tables of the parent window and the sub-window also store the routine number of each processing for the window and other information, and the batch display is restarted. After that, the state becomes the same as the state before the pause.

Further, by storing the window management table in the auxiliary storage or the like, the same plurality of windows can be displayed even when the power is turned on again after the power is turned off, and the process can be restarted.

〔The invention's effect〕

According to the present invention, it is possible to control the temporary non-display and the resumption display of the main window based on an instruction to suspend the display of the main window displayed on the display screen and to resume the display after the window is not displayed. When the display of a plurality of subwindows belonging to the main window is set for the main window, all of the subwindows belonging to the main window are synchronized with the temporary non-display of the main window. Can be automatically set to the non-display state, and all the sub-windows belonging to the main window automatically overlap in the order according to the display priority in synchronization with the resumption display of the main window. It can be displayed again in the state.

Also, when the main window and the sub-windows belonging to the main window are erased and displayed from the display screen and the windows are collectively restarted and displayed, they are displayed on the display screen. By simply selecting and instructing the window display restart instruction menu item, the main window and each of the sub-windows can be collectively and immediately restarted and displayed while maintaining their display order.
