Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a screen display control device for an information processing device such as a computer. The present invention relates to a screen display control device that displays a screen that has been updated.

[Background of the invention]

BACKGROUND ART In computers and the like, a plurality of application programs and the like are executed in parallel. For example, the process of executing an application program, etc.
Monitored by a display device such as RT. Therefore, when a plurality of application programs and the like are executed in parallel, a request is generated to monitor the processing process of each program using one display device. Conventionally, this kind of requirement has been solved by a screen splitting technique. This divides the display screen into multiple sections,
Each divided screen is assigned to each program. In some cases, the size, position, number, etc. of each split screen can be specified arbitrarily. This allows you to monitor the execution process of multiple programs at once, which is extremely effective in terms of operation.When a certain process is executed by a computer with this type of function, each program can be adjusted as necessary. The divided screens are set on the display screen of the display device, but there are cases where it is desired to display any one of the multiple divided screens on the entire display screen, such as during processing or at the end of processing. Conventionally,
In order to erase a split screen that is no longer needed from the display screen, a screen erase function is provided, and by executing this function, the desired split screen is erased. However, the conventional method does not take into consideration leaving any one split screen as described above, so the screen erasing function can only be achieved for each split screen. Therefore, if the total number of split screens is displayed, in order to display any one of them on the entire display screen, specify the split screen that is no longer needed, and then erase the screen for this specified split screen. The operation of executing a function had to be performed for each split screen that was no longer needed. Therefore, there were problems such as troublesome operation.

Regarding the above-mentioned split screen display, see Japanese Patent Application Laid-Open No. 51-
No. 114829 is a reference.

[Purpose of the invention]

The present invention has been made in view of the above points, and its purpose is to enable any one of the plurality of split screens displayed on the display screen of one display device to be displayed by a simple operation. An object of the present invention is to obtain a screen display control device capable of displaying information on the entire display screen.

[Summary of the invention]

The screen split display includes a plurality of screen storage units each corresponding to a display screen of a display device, a display management storage unit that stores the display position of the stored content of each screen storage unit on the display screen, and a display management storage unit that stores the display position of the stored content of each screen storage unit on the display screen. This is achieved by comprising a display control means for displaying the storage contents of the screen storage section designated for display at a predetermined position on the display screen based on the storage contents of the storage section. That is, one of the screen storage units is assigned to each program executed by a computer or the like. Each program assumes that the assigned screen storage section is the display storage section corresponding to the display screen and writes display information thereinto. The contents of which screen memory assigned to which block and at which position on the display screen are to be displayed on a divided screen are stored and registered in the display management memory. As a result, the display control means controls the storage content of the desired screen storage section to be displayed at a desired position on the display screen based on the storage information of the display management storage section. Therefore, in the present invention, the display screen A designation means is provided for designating any one of the plurality of divided screens corresponding to the plurality of screen storage units displayed on the screen. Various coordinate input devices, keyboards, etc. can be used for this K. Furthermore, display management that updates the storage content of the display management storage unit rather than displaying the display position f1t on the display screen of the screen storage unit corresponding to the split screen specified by the specification means on the entire surface of the display screen. and means.

In this way, the display management means rewrites the storage contents of the display management storage section to the desired state by specifying the split screen that is desired to be kept from among the plurality of split screens using the specifying means. Therefore, the display control means that controls the display state based on the contents of the display management storage section displays the stored contents of the screen storage section corresponding to the desired split screen on the entire display screen. That is, any one of the plurality of divided screens displayed on the display screen of the display device can be displayed on the entire display screen by a simple operation of designating it using the designation means.

, window range, position change routine tKD, window deletion routine WDI.

and a window organizing routine W that forms the main part of the present invention.
AR, command recognition routine COM, and window rewriting routine WRY. Window close execution routine we
L is means for accomplishing the operation of closing any window opened on the display screen Sa. Conversely, the window opening execution routine WOP is a means for accomplishing the operation of opening a closed window on the display screen SC.

The window range and position change routine WED is displayed on the display screen 8.
This is a means for changing the size and position of a window opened on the display screen 80.

The window deletion routine WDL is a means to accomplish the operation of deleting the application program corresponding to any window.

The program organizing routine WAR, which forms the main part of the present invention, will be described later. Each of these routines weL, WOP,
The execution results of WED, WDL, and WARVi are delivered to the window rewriting routine wRwK.

Indicates the icon "remaining" corresponding to TUJ. Next, the left button switch Bt of the mouse 140 is pressed to designate the "remain" icon of the window WD. Then, in step 14c, the display screen Sa is organized, and as shown in FIG.
) is obtained.

Each routine WCL, WOP, WED, WDL.

The WAR activation command is issued using the mouse 140 on the display screen SC.
This is achieved by specifying the predetermined icon displayed above. The command recognition routine COM is an operating means for this purpose, and interprets information from the mouse 140, starts a predetermined routine based on the result, and transfers subsequent processing to the routine. The window control program wc't'p, which has such functions, controls all windows.
Control the window's own state.

The program execution control program PECP starts the application program APP corresponding to the window where the graphic cursor P1 is located based on the position information of the graphic cursor P1, and if a different window is specified, it corresponds to the window specified immediately before. App cage to? The application program APP is stopped and the application program APP corresponding to the different window is started. In this way, program execution control/
Program PIICOP is application program A
Controls the execution of the PP, and when the application program is running under normal conditions, the program P
Execution is controlled under KOP.

FIG. 15 is a flowchart showing the relationship between the program execution control program PECP and the window control program WOTP when the mouse 140 is moved under the control of the window management program WMGP. The position information of the mouse 140 is - for example, 20 [m5ac
This is brought about by a mouse interrupt processing routine (not shown) that is periodically activated every l. For example, when a mouse interrupt occurs every 20 [m5ec], the mouse interrupt processing routine extracts the position information of the mouse 140 and controls the movement of the graphic cursor P1 according to the position information as shown in FIG. 7. Normally, the application program When running APP - application program A under the program execution control program PECPO
PP is working. Then, the process moves to a mouse interrupt processing routine every 20 [m5ec], and this routine transfers the position information of the mouse 140 at that time to the window execution control program WCTP. When the mouse 140 is moved, the window control program wc'rp determines whether the mouse 140 points to an icon that is a command based on its position information, and if it points to a command, executes the routine war corresponding to the command. ,
W.O.P.

WEP, WDL, and WAR are executed, and if not, preparations are made for execution of the application program APP corresponding to the window pointed to by the graphic cursor P1. Window execution control program Wl! When exiting from i0P, the processing is applied to the program execution control program PE0P, which executes a predetermined application program APP. In this manner, the window control program WECP and the program execution control program PHOT are activated alternately by mouse interrupts.

FIG. 16 is a flowchart showing the internal configuration of the window control programmer iwaTp. This program wc'
As described in FIG. 15, rp is activated by a mouse interrupt inside the window management program WMGP. When the program W (!TP) is called, the window control program WCTP first saves the information of the currently executing window to a predetermined storage area of the RAM 2 in step 16a, and then executes the command recognition routine COM in step 161. Call and execute. In the command recognition routine COM, it is determined whether the graphic cursor Pi points to an icon that means a command,
If this points to a command icon, execute the corresponding command. If it is not a command or after executing a predetermined command, preparations are made to execute the application program APP corresponding to the corresponding window, as shown in step 16c. Preparation here means restoring all the window information that was saved in the RAM 2 in step 16a and setting the conditions for re-execution.

FIG. 17 is a flowchart showing details of the command recognition routine COM. The outline of the processing by this means is as follows. That is, the coordinate position of the graphic cursor P1 on the display screen SC is checked, and it is determined whether this is the position at which an icon representing a command displayed on the display screen Sa is indicated. When the graphic cursor P1 points to an icon representing a command, the corresponding command execution routine waL is executed.

WOP, Wl! Start fD, WDL, and WAR. This figure will be explained below. First, in step 17a, it is determined whether the graphic cursor P1 points to the range or position change icon 16 displayed on the display screen Sa. This determination will be described later. Here, the graphic cursor P1 is set to the range-position change icon 16.
is specified, the entire process goes to step 17b, and the window range and position change routine W]lCD'i
i Start If in step 17a, the graphic cursor P1 does not point to a range or position change icon, the process moves to step 17c. In step 17c, it is determined whether or not the graphic cursor P1 is pointing to a deletion icon. If so, the process is moved to step 17 (i) and the window deletion routine WD is executed.
Start L. If no instruction has been given, the process moves to step 17e.

Similarly, in steps 17θ, 17g, and 171, the graphic cursor P1 moves to the organize icon IL window open icon 19. Determine whether the window close icon 15 is present, and if so, step 17f, 17h, 171
The window organizing routine WAR and the window opening execution routine w OP are respectively performed.

Execute the window close execution routine WOL. If any of the routines WED, WDL, WAR, WOP, WCL has finished executing, or if the graphic cursor P1 is not pointing to any icon, the process moves from the routine CQM to step 16c in FIG. 16. .

FIG. 18 shows steps 17a and 17c of FIG. 17.

17 is a 70-chart showing an example of the command icon determination means executed in 17e, 17g, and 171. In realizing this means, position information of each icon is stored in advance in a predetermined storage area of the RAM 2. That is, the position of each icon on the display screen sC is determined in advance. Therefore, the display range of the icon is determined in advance, and the coordinate information of the range is stored in a predetermined storage area of the RAM 2. For example, FIG. 19 shows the display screen EO
J: This shows the organizing icon "remaining" in VC, and its display range can be expressed by the coordinates of the upper left end point XcL and the lower right end point ICr. Therefore, as shown in FIG. 20, the X coordinate ICtx, Y coordinate ICty of the upper left end point Ct, and the X coordinate arx of the lower right end point Icr.

The Y coordinate ICry is stored as a set in a predetermined storage area of the RAM 2. Then, such a storage area is allocated to each icon, and coordinate information is stored in each icon. When the command icon determining means is activated, this means first reads coordinate information of the graphic cursor P1 on the display screen SC in step 18a. The coordinates of the graphic cursor P1 on the display screen SC are the second
It is managed by a Kahnle memory section provided in the CRT control circuit shown in the figure or a Kahnle memory section similarly provided in the RAM 2. Therefore, this step 18a is achieved by reading out the storage contents of the storage section. In the subsequent step 18b, the position information ICt, ICr of the icon to be determined is read from a predetermined storage area of the RAM 2. In steps 18c and 18d, it is determined whether the coordinate position of the graphic cursor P1 is within the range indicated by the upper left end point IC2 and the lower right end point ar of the icon. If the conditions of steps 18c and 18d are both satisfied, ,
In step 18e, it is determined that the graphic cursor P1 has specified the corresponding icon, and if the condition is not satisfied even if -100, it is determined in step 18f that the graphic cursor P1 has not specified the corresponding icon.

Next, the window opening execution routine wo:p, the window closing execution routine WCL, and the window IM filling routine WAR will be explained with reference to FIGS. 21, 22, and 23. For these explanations, it is assumed that in this embodiment there are a maximum of four windows - these are defined in eight predetermined patterns shown in FIG. 24, and each of these patterns is shown in FIGS. 25 and 26. The pattern shall be changed according to the state transition diagram shown in . In addition, FIG. 24 defines the pattern, and each window WDI S VID2* WD3* WD
Please note that this does not specify the size of 4, etc.

Further, in FIG. 24, the number attached above each display screen 8c is a pattern number indicating the pattern concerned. and,
The number enclosed in a circle and shown in parentheses in FIG. 25 indicates the pattern number. In addition, the display screen SC of 0RT1 is 640 in the horizontal direction, that is, in the X direction, and 4 in the vertical direction, that is, in the Y direction.
00 can be displayed, and its upper left corner coordinates have an X coordinate of 0 and an X coordinate of 0, and its lower right corner coordinates have an X coordinate of 639 and an X coordinate of 399. 1st, 2nd
In FIG. 5, Fix and Piy are the X coordinates Yi of the graphic cursor P1 on the display screen sc. 1
First, FIG. 25 will be explained.

When opening a window at the starting point, the graphic cursor P1 may be located at any coordinate position on the display screen SC. In order to move the display screen SC from pattern 1 to pattern 2, the X coordinate of graphic cursor P1 must be r.
This is done either because it is not OJ or r399J. From pattern 2 to pattern 4, if the X coordinate position of one graphic cursor P1 is rOJ or more,
319J or less, and the X coordinate is "0" or more "l 99
J or less, or the X coordinate is "320" or more "6"
39'' or less, and the -YX coordinates must be greater than or equal to rOJ and less than or equal to rl 99J. Thereafter, similarly, transition from one pattern to another is made based on the determination conditions described in the figure.

Note that here, "OR" is a logical sum condition, and [andJ is a logical product condition. FIG. 26 is a transition diagram showing the case where windows are closed one after another, and the numbers surrounded by circles and marked with a cutlet are the display pattern numbers of the display screen Sa shown in FIG. 24, as in FIG. 25. .

Here, for example, in order to transition from pattern 8 to pattern 4, window WD or window WD4
In order to specify deletion of either one of them and transition to pattern 5, select window WD.

Alternatively, one of the windows WD is specified to be deleted. Hereinafter, it is assumed that the pattern at the time of deletion similarly changes based on the transition diagram of FIG. 26.

Hereinafter, with reference to FIGS. 24, 25, and 26,
22, and @23 will be explained. FIG. 21 is a flowchart showing the window opening execution routine WOP, and this routine WOP is performed in step 17 of FIG.
This is executed when the graph ink cursor P1 specifies the window open icon in g. 1st, step 2
In 1a, it is determined whether or not the left button switch St of the bimouse 140 is pressed.
In step 211), the coordinate position information of the graph ink cursor P1 on the display screen BC at the relevant time point is saved. The storage section for this coordinate position information may be a predetermined storage area of the RAM 2, or may be a cursor storage section provided in the CRT control circuit 9. When it is detected in step 21a that the left button switch St of the mouse 140 has been released, window display pattern information on the current display screen SC is fetched in step 21c. That is, in this embodiment, the current display screen SC
The pattern shown in FIG. 24 is always memorized as the upper wind pattern. As shown in FIG. 11, this wind pattern information storage section WP is R
Set to a predetermined address of AM2. That is, step 21C reads the storage contents of this preset storage section WP of the RAM 2. In the following step 21d, a window pattern is determined based on the state transition diagram of FIG. 25 from the current window pattern information read in step 21c and the coordinate position information of the cursor P1 saved in step 21b, and the window pattern is The pattern information is set in the window pattern information storage section WP described above. Steps 21e and 21f are Fi window rewriting routines WRW, in which all opened windows are retraversed based on the window pattern determined in step 21 (l).

FIG. 22 is a flowchart showing the window closing routine WOL, which is executed when the graphic cursor P1 designates the window closing icon in step 171 of FIG. 17. Here, step 22a, step 221) is step 21a shown in FIG.

This is similar to step 211). And step 22
In c, the cursor P saved in step 221)
It is determined whether the coordinates of 1 are within the icon area ION of the display screen SC. If the coordinates of the cursor P1 are not within the icon area CN, the command cannot be executed. If the coordinates of the cursor P1 are within the icon area ION, the current window pattern information is read out from the predetermined storage portion wp of the RAM 2 in step 22a, similar to step 21c in FIG. In the following step 22d, step 22
Based on the current window pattern information read in step d and the coordinate position information of the cursor P1 saved in step 221), the window pattern is determined based on the state transition diagram of FIG. Set it in the pattern information storage section WP. Step 21e.

21f is a window rewriting routine WRY, which rewrites all of the opened windows based on the window pattern determined in step 21d.

FIG. 23 is a flowchart showing the window organizing routine WAR, and this routine WAR is executed when it is determined that the graphic cursor P1 has designated the window organizing button 18 at step 17θ in FIG. When executing this routine WAR, two new storage units Fi are set in predetermined storage areas of the RAM 2. One is the memory section RWNO that stores the window numbers of the windows that are left when organizing the windows.The other is the memory section TNO that stores the window numbers at one point in time.The window numbers are for each window WD, WD. ,,W
D8. It is a numerical value sequentially assigned to WD4, and in this case, window WD is "l".

Window WD, f r2J, window VD, are set to "3" and window WD4 is set to "4". When the window arrangement routine WAR is started, first, in step 23a, current window pattern information is read out. This is similar to step 21C in FIG. 21 and step 22d in FIG. 22.

Next, in step 231), the number of windows to be left when organizing the window number is determined from the coordinate position of the graphic curve P1 on the display screen BC and the window pattern information read out in step 23a, and this number information is used as the window number. Set it in the memory section RWNO. Then, in the subsequent steps, the memory 1RWNOK: process of displaying the set 1iI window on the display screen Sa and closing other windows is executed. To do this, first, in step 23c, the window number "1" is temporarily stored in the in-to number storage unit TNO.Subsequently, in step 23d
At this point, it is determined whether the stored content of the in-to number storage unit TNO is 4 or more. In this embodiment, since the maximum number of windows is "4", it is determined whether the number is 4 or more. In the next step 23e,
It is determined whether the contents of the window number storage section RWNO and the contents of the temporary in-to number storage section TNO match. If these do not match, the temporary window number storage section T
Since the window with the number stored in NO may be closed, the window corresponding to the number stored in the into-number storage unit TNO is temporarily displayed as an icon in the icon area ONK in step 23f. Then, in step 23g, the contents of the in-to number storage unit TNO are incremented by "1", and the process moves to step 23d.

The processing in steps 23a, 23θ, 23f, and 23g is performed in step 23e, where the storage contents of the storage unit TNO and the storage unit RWNO are
At step 23θ, which is repeatedly executed until the memory contents of the temporary window number memory %TNO match the memory contents of the window number memory %TNO or the memory contents of the memory TNO exceeds "4" in step 23d, the memory contents of the temporary window number memory %TNO and the window number memory RWN
If the stored contents of O match, that is, the window currently being processed is the window to be left.

The process moves to step 23h. In this step 23h -
, the contents of the window pattern storage WP are changed to the pattern "1".
”. Then, according to the next step 231,
Window rewriting is executed in the window rewriting routine WRW, and the window specified to remain on the display screen SCK is displayed in pattern "1" in FIG. 24C.Then, the process moves to step 23g. , the process of closing other windows is repeated.

The window rewriting routine WRY shown in FIGS. 4 and 12 includes the routines WAR and WDL, as outlined in the description of each routine above.

Based on the execution results of WED, WO'P, and weIJ, the display management storage units DMM, , DMM, , DMM, , DMM, corresponding to each window WD, WD, WD, WD4 are
Update the memory contents of. That is, in FIGS. 21, 22, and 23, step 21d, step 22
e. Based on the window pattern information determined and stored in step 23h, the display management storage unit DMM
, , DMM, , DMM, , DMM, are rewritten to a predetermined state. Here, for example, window WD,
is specified to remain on the display screen SC, and the window rewriting routine WRY based on the window organizing routine WAR is executed.
The processing for the display management storage unit DMM is as follows. That is, since the window to be left is window WD, the upper left corner coordinates of the display screen SC are set and stored in the memory section ML of the display management memory section DMM, and the lower right corner coordinates of the display screen Sa are set and stored in the memory section MR2. All other display management storage units DMM, DMM, etc. are cleared. As described above, the display control means DCT has a screen storage section V CB 1 * V corresponding to each application program.
The storage contents of CB 1 * V OB 3 * V OB 4 are stored in the corresponding display management storage units DMM, , DMM
, , DMM, , DMM, the display on the display screen SC is controlled based on the stored contents of each setting. This will be explained as follows, based on the above example, that is, the contents of the display management control unit DMM after it is specified to leave the window WD2. That is, the display control means DOT
The contents of the window pattern information storage section are pattern “1”.
” and the display management storage unit DMM! Since the coordinate information is stored only in the screen storage section VCB, only the contents stored in the screen storage section VCB are transferred and stored in the refresh memory 10 shown in FIG. 2. Therefore, each window is displayed on the display screen SO in a predetermined window pattern determined by window pattern information or the like.

By doing the above, if necessary, use the window opening execution routine WOP to designate the 1i-embedded icon 18 of the window you want to keep among the multiple windows successively interposed on the display screen SC using the graphic kernel P1, By a simple operation of specifying the screen position using the screen position specifying device fii14, only the necessary windows can be left on the display screen SC and other windows can be closed.

In the above embodiment, a case has been described in which a CRT is used as a display device, but the present invention is not limited to this, and various display devices such as a display device using liquid crystal can be used. In addition, the number of windows, that is, split screens, is based on the power (4) as an example for convenience of explanation.
This number is arbitrary, and the number of window patterns is also arbitrary, and the present invention is not limited to these numbers. In fact, the more split screens are opened on the display screen SC, the greater the effect will be. We have explained the case where this is done using the screen position designation device 14, but in this case it is better to specify a specific window using an input device such as a keyboard. Furthermore, in this embodiment, the screen storage unit VCB can be used as long as it is a means that can specify C.

VCB, , VCB, , VCB4 and display management storage section D
MM,, DMM,, DMM3. DMM4 etc. to RAM
Although a case has been described in which two locations are set, the physical locations thereof are not particularly limited, and may be any location where diagnosis can be made in the same manner.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, among the plurality of split screens displayed on the display screen of the display device,
It is possible to obtain a screen display control device that can display any one of them on the entire display screen with a simple operation.
