Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window display method in an engineering workstation such as CAD, and more particularly to a window display method of a multi-window function corresponding to a network.

[0002]

2. Description of the Related Art U developed at AT & T Bell Laboratories in the United States
Due to the spread of operating systems (OS) capable of simultaneously performing a plurality of processes such as NIX and the spread of computer networks, workstations, personal computers and the like have a screen as a means for displaying a plurality of processes on one display screen. A multi-window function that can display multiple windows inside and display each process in each window
In particular, "X developed at Massachusetts Institute of Technology
It has become common to have a multi-window function corresponding to a network such as "window system".

In the conventional window display method having the above-mentioned multi-window function corresponding to the network, an application program is executed on another workstation on the network and a new window created by the application program is being used. Can be displayed on the display screen of the workstation. The specific display method will be described below with reference to FIG.

FIG. 26 is a block diagram showing the configuration of workstations connected by a network.

In the figure, 100 is a network, 1
01 and 111 are workstations, 102 and 112 are displays, 103 and 113 are mice, 104 and 11
4 is a keyboard, 105 and 115 are central processing units, 10
6 and 116 are storage devices, 107 and 117 are display control units,
Reference numerals 108 and 118 are input control units, and reference numerals 109 and 119 are network control units.

First, the operator operates the keyboard 104 of the currently used workstation 101 to remotely log in to another workstation 111 on the network 100 and execute the application program using the central processing unit 115. At this time, the display destination is designated as the workstation 101. This designation is stored in the storage device 116. Here, when the application program issues a window creation request, the central processing unit 115 instructs the network control unit 11 to the display destination workstation 101 stored in the storage unit 116.
This request is transmitted from the network 9 to the network 100. The transmitted request is received by the network control unit 109 and processed by the central processing unit 105. Then, information such as the position and size of the created window is sent to the display control unit 107 and the window is displayed on the display 102.

However, in the conventional display method described above, the side that issues a request for window creation issues a request without considering the display screen at all, and the side that creates and displays the other window responds to the received request. It just created and displayed a window that followed. Therefore, in a network in which various types of workstations are mixed, the display position of the window may be completely out of the display screen because the display screens have different sizes.

FIG. 3A is a diagram showing an example of a window for which the application program requests creation.

In the figure, four windows W1 to W4 are created in the illustrated positions and in the illustrated sizes.

FIG. 3D is a diagram showing an example of a display screen when the window shown in FIG. 3A is displayed on a display having a small screen by the conventional window display method.

In FIG. 1, the window W1 is entirely displayed on the display screen, but the windows W2 to W4 are out of the display screen. Window W2
If a part of the window protrudes like the above, you can move the target window by the window moving function provided by the conventional multi-window function and display the entire window on the display screen,
When the window W3 and the window W4 are completely out of the display screen, the window cannot be moved, and therefore it is completely impossible to display the window on the display screen.

Recently, for example, an application program corresponding to a multi-window having a window for input / output only for receiving an instruction from an operator or displaying a processing result has been developed. As described above, when the window is completely projected, it becomes impossible to give an instruction to continue the processing and to see the processing result.

On the other hand, in the conventional multi-window display method, when many windows are displayed on the screen, the windows may overlap each other. In this case, if you want to see the contents displayed in a window that is partially or wholly obscured by another window (hereinafter referred to as the lower window), or if you want to enter a command, the entire window is It needs to be displayed (hereinafter referred to as the highest level).

When only a part of the lower window is covered, it is possible to display it at the top by a single operation by clicking the displayed part with the mouse. In this case, The operator needs to know where to open the window. But usually
Since many windows are displayed on the display screen, it is difficult for the operator to know all where the target window is.

Further, when all the windows are covered, the windows cannot be directly operated. Therefore, the window operation such as moving, reducing, or iconifying the covered windows is performed many times to obtain the target window. It is necessary to perform the above operation until a part of appears. In the worst case, it is necessary to perform window operations by the number of windows covering the target window (hereinafter referred to as the upper window).

Further, if it is not known where the target window is, it is necessary to perform the operation of displaying the window at the top by trial and error, so that many window operations are required.

As a solution to this problem, there is a technique described in Japanese Patent Laid-Open No. 4-67647. When the lower window is completely hidden, this window is reduced to a predetermined size, displayed in the icon window display area, the icon is released when needed, and the topmost window can be displayed with a single operation. To display. However, this method is a solution only for the case where the window is completely hidden, and the case where it is not completely hidden is not considered, so the problem of partially hiding described above still remains. .

Further, when the icon is displayed, the content displayed in the corresponding window cannot be known only by the icon display. Therefore, unless the user knows which icon display the target window is, it is tentatively tried. It was necessary to cancel the icon display.

[0019]

As described above, when the application program is executed by another workstation on the network and the window created by the application program is displayed on the display screen of the workstation in use, the conventional network is used. In the window display method of the multi-window function corresponding to, the side that requests window creation issues a request without considering the display screen at all, and the side that creates the window and displays it on the display screen follows the received request. Just create and display.

Therefore, depending on the size of the display screen, the required display position of the window may be completely out of the display screen, so that the application program cannot be executed at all or the execution result of the application program cannot be displayed. There is a problem that it becomes completely impossible to see.

The present invention has been made in view of the above circumstances, and an object thereof is to execute an application program on another workstation on the network and use a window created by the application program. When displayed on the display screen of a workstation, it is possible to display at least a part of the window within the display screen without completely protruding the window from the display screen regardless of the size of the display screen. It is to provide a window display method.

Another object of the present invention is to execute the application program on a workstation different from the workstation being used by the operator and to open a window created by the application program by the operator. An object of the present invention is to provide a method of displaying a window that can be displayed on the display screen by moving the window even when the window is completely out of the display screen when being displayed on the display screen of the station.

FIG. 10 is a diagram showing an example of a display screen when the window of FIG.
FIG. 10B is a diagram showing an example of the display screen when the window of FIG.

First, the window display will be described with reference to the flowchart of FIG.

In step S111, the network controller 23 receives a request for creating a window to be displayed on the display 33 of the workstation 21 from the network 22. As shown in FIG. 3A, as a window creation request, the upper left point of the screen is the origin, the horizontal direction is the x-axis (rightward is positive), and the vertical direction is y-axis (downward is positive). The coordinate value of the upper left point, the coordinate value of the lower right point, and other information are given.

In step S112, the window coordinate value extraction processing unit 2 obtains the coordinate value (X _L , Y _L ) of the upper left point and the coordinate value (X _R , Y _R ) of the lower right point of the window from the received request.
Determined by 4. In step, the window display processing unit 29 displays the window on the display 33 according to the extracted window coordinate value. Step S11
4, the maximum value x _MAX of the x coordinate value of the virtual region and the maximum value Y _MAX of the y coordinate value are obtained in step S112 (X _R ,
Y _R ) and whether the window is completely included in the virtual area is determined by the protrusion determination unit 25. X _R is X
_{If it is} larger than _MAX or Y _R is larger than Y _MAX, it is determined that it is out of the virtual area.

First, as shown in FIG.
Consider a case in which the window W1 of (a) is newly created. In this case, the virtual area is the size of the display screen, that is, the origin and (X _MAXO , Y _MAXO ) as shown in FIG.
Is a rectangular area whose diagonal point is, and W1 is determined not to extend from the virtual area. If it is determined in step S114 that it does not overflow, the window symbol creation unit 27 calculates the reduction ratio of the virtual area and creates the window symbol corresponding to W1 in step S116. If the size of the virtual area display window is W _X × W _Y ,
The reduction ratio in the X direction is W _X / X _{MAXO for} R _X , and the reduction ratio R _Y is W _Y / Y _{MAXO in} the Y direction.

Therefore, the window symbol is (X _L 0 /
R _X , Y _L 0 × R _Y ) is the upper left point, (X _R 0 / R _X , Y _R
It becomes a rectangle with the lower right point being 0 × R _Y ). Step S11
At 7, the window symbol display processing unit 28 displays the window symbol in the virtual area display window. A display example of the display screen at this time is shown in FIG.
Shown in. In the figure, 34 is a virtual area display window. A display example of the virtual area display window 34 is shown in FIG.

Next, consider the case where W2 is added. In this case, when determining the protrusion in step S114, the relationship between the virtual area and the window is as shown in FIG. 7B, and it is determined that W2 protrudes. Step S11
If it is determined in step 4 that the virtual area extends, the virtual area is expanded by the virtual area expansion unit 26 in step S115. X
Since _R 2 is greater than the X _MAX0 maximum value X _MAX1 of the X-coordinate values of the new virtual region becomes (X _R 2 + X _margin). Then, in a succeeding step S116, a window symbol is created, and in a step S117, the window symbol is displayed. A display example of the display screen at this time is shown in FIG. 8B, and a display example of the virtual area window is shown in FIG. 9B.
Shown in.

Further, consider the case where W3 is additionally created.
The relationship between the virtual area and the window in this case is as shown in FIG. Since step S114 in Y _R 3 is larger than the Y _{MA X0} maximum value Y _MAX1 of the Y coordinate values of the new virtual area extends the virtual area as (Y _R 3 + Y _margin), creation of the window symbol in step S116,
In step S117, the window symbol is displayed. A display example of the display screen at this time is shown in FIG. 8C, and a display example of the virtual area display window is shown in FIG.
It shows in (c).

Finally, consider the case where W4 is added. The relationship between the virtual area and the window in this case is as shown in FIG. In step S114, X _R 4,
Since Y _R 4 is greater than X _MAX1, Y _MAX1 respectively, the maximum value X _MAX2 of the X-coordinate values of the new virtual area (X _R 4 + X
_Margin ), and the maximum Y value of the Y coordinate value of the new virtual area
_MAX2 expands the virtual area as (Y _R 4 + Y _margin ), creates a window symbol in step S116, and displays the window symbol in step S117.
A display example of the display screen at this time is shown in FIG. 8D, and a display example of the virtual area display window is shown in FIG.
It shows in (d).

FIG. 10 (a) shows the structure of FIG.
An example of the result of creating and displaying all the windows shown in (a) is shown. Window W3 and window W4
Is not displayed because it is out of the display screen, but four window symbols are displayed in the virtual area window 34 as shown in FIG. 9D.

Next, FIG. 6 shows the method of moving the window.
It will be described based on the flowchart shown in FIG.

In step S121, the window symbol corresponding to the movement target window in the virtual area display window is selected by the mouse 30. In step S122, the window symbol movement processing unit 31 executes step S122.
The window symbol selected in 121 is moved to obtain the coordinate value (X _LS , Y _LS ) of the upper left point and the coordinate value (X _RS , Y _RS ) of the lower right point of the new display position. In step S123, the window symbol display processing unit 28 displays the window symbol in the virtual area display window according to the new coordinate values obtained in step S122.

In step S124, the new coordinate value of the window symbol obtained in step S122 by the window symbol movement processing unit 32, the reduction ratio in the X direction, and the Y-direction.
The new display position of the window is calculated according to the direction reduction ratio. That is, the coordinate value of the upper left point (X _LS / R _X ,
Y _LS / R _Y ), coordinate value of lower right point (X _RS / R _X , Y _RS / R
_Y ) is calculated. In step S125, the window display processing unit 29 displays the window according to the new display position of the window obtained in step S124.
The movement of the window symbol in steps S121 to S123 can be easily realized by using the window movement function provided by the conventional window system.

FIG. 10B is a diagram showing an example of the display result when the window symbol in the virtual area display window 34 in FIG. 10A is moved.

Since the window symbol corresponding to W3 has been moved upward and the window symbol corresponding to W4 has been moved to the upper left, W3 and W4 have moved accordingly and are now displayed on the display screen.

In the embodiment described above,
Although the origin of the window position is the upper left point of the screen, the present invention is not limited to this, and can be applied when an arbitrary point is the origin.

Further, as the protrusion determination, the coordinate value of the lower right point of the window and the maximum value of the x coordinate of the virtual area and y.
The judgment is made by comparing with the maximum value of the coordinates, but the present invention is not limited to this, and can be applied to the case of making a judgment using any of the coordinate values of the four corners of the window according to the position of the origin. It is a thing.

When the window symbol is displayed in the virtual area display window, the size of the display screen,
That is, when the origin and the rectangular area whose diagonal point is (X _MAX0 × R _X , Y _MAX0 × R _Y ) are overlapped and displayed, the range displayed on the display screen becomes clear and the protruding window is displayed. There is an effect that the amount of movement can be easily grasped when moving inward, and the window symbol corresponding to the target window can be easily recognized.

The operation of FIGS. 11 and 12 will be described below with reference to FIGS. 15 to 25.

First, FIG. 15, FIG. 17, FIG.
The embodiment of FIG. 11 will be described based on the flowchart of FIG.

First, the case where a window is newly displayed on the screen will be described. The flowchart in this case is FIG. First, in step S131, the input control unit 45 takes in a request for creating a new window specified by the operator in the window menu or the like, and requests the window state control unit 46 to display the new window. The window state control unit 46 notifies the window management unit 47 of the identification number, coordinates, state and the like. The window management unit 47 holds the window display information in the window management table. Window display 48
Displays a window on the screen according to the display information of the window management unit 47. Thus, in step S131, a new window is displayed on the screen.

Next, in step S132, the correspondence table management unit 4
At 9, the window identification number is received from the window control unit 46, the command name display area number corresponding to the window identification number is assigned, and the set is added to the correspondence table. Next, in step S133, the command name display unit 50 redisplays the command name display area. FIG. 25A shows two windows newly created and displayed in this manner.

Next, the window display when a command is input in a certain window will be described.

The flowchart in this case is shown in FIG. First, in step S151, the command name input by the operator using the keyboard is read by the input control unit 45. Next, in step S151, the designated position extraction unit 51 extracts the position pointed to by the mouse pointer at that time,
The designated window determination unit 52 determines the window for which the position previously obtained is designated, and the identification number extraction unit 55 extracts the window identification number.

Next, in step S153, the command name read by the command name extraction unit 55 is extracted, and the window management unit 47 assigns the command name to the execution command information 83 of the window management table shown in FIG. 22 corresponding to the window identification number. Hold. Next, step S15
In step 4, the correspondence table reference unit 53 refers to the correspondence table managed by the correspondence table management unit 49 and extracts the command name display area number corresponding to the identification number. Next, step S155.
The command name held in the window management table is displayed in the display area corresponding to the command name display area number. FIG. 25B shows an example of a screen display when command names ls and make are entered in the windows 92 and 94 of FIG. 25A.

Next, the window display when the operator designates the command name display area with the mouse 43 will be described. The flowchart in this case is FIG.

First, in step S161, the input control unit 45
Thus, the information that the operator has designated the command name display area is fetched, and the designated position extraction unit 51 reads the position designated by the mouse 43. Next, step S
In 162, the designated window determination unit 52 determines that the region is the region designated from the designated position, and the display region number extraction unit 53 extracts the command name display region number for the extracted position. Next, in step S163, the correspondence table reference section 56 obtains the window identification number of the window corresponding to the command name display area number.

Next, in step S164, the display information is changed so that the window corresponding to the identification number obtained by the window management section 47 is displayed at the top, and the window display section 48 displays the window at the top. FIG. 25C is an example of a screen display when the position displayed as ls in the command name display area in FIG. 25B is designated by the mouse and the corresponding window 92 is displayed at the top.

Next, the embodiment shown in FIG. 12 will be described.

First, the case where a window is newly displayed on the screen will be described. The flowchart in this case is shown in FIG. First, in step S141, the process described in step S131 is performed, and the window display unit 48 displays a new window on the screen. Next, in step S142, the same process as step S132 is performed to create a correspondence table. Next, step S14
In step 3, the same processing as step S133 is performed, and the command name display area is displayed again.

Next, in step S144, the window state determination unit 57 determines whether or not other windows are hidden with the newly created window as the top level, and the window management unit 47 responds the determination result to each window. It is held in the status information 82 of the window management table. The window state is "I" if the window is an icon, "T" if it is displayed at the top, and "H" if it is partially or entirely hidden. The function of the window determination unit 57 will be described later.

The window management unit 47 holds the determination result of the state thus obtained in the state information 82 of the window management table corresponding to each window. Next, in step S145, the window state display unit 58 extracts the window state from the state information 82 of the window management table, and obtains the command name display area number 71 from the correspondence table of the correspondence table management unit 49. To display. The window status is displayed in the window status display area.

Next, the window status display when the window status is changed will be described. The flowchart in this case is shown in FIG. Here, changing the state of a window includes moving the window, iconizing, canceling the icon, deleting the window, and changing the size.

First, when the window state is changed in step S181, the window state determination unit 57 next determines the window state in step S182. Here, the window status is determined when the window is moved, the moved window is the top, when the size is changed, the resized window is the top, and when the icon is released, the icon is released. Is the top level, it is determined whether or not other windows are hidden, and the determination result is the window management unit 4
7 holds in the status information 82 of the window management table corresponding to each window. Next in step S14
It is displayed in the status display area in the same manner as 5.

Next, the state change and state display of the window when the command name display area is designated by the mouse will be described. The flowchart in this case is shown in FIG.

From steps S171 to S174, the same processing as steps S161 to S164 is performed. In step S175, the window state determination unit 57
It is determined whether or not the window is hidden, and the window management unit 47 holds the determination result in the status information 82 of the window management table corresponding to each window. next,
Similar to step S175, it is displayed in the status display area.

Finally, the window display when a command is input to the window is the same as FIG. 11 according to the flowchart shown in FIG.

Here, the determination of the window state, which is the function of the window state determination section 56, will be described. If there is another window W2 above a certain window W1, the window state is judged to be lower than the window W1,
If not, the window W1 is determined to be the highest. However,
If the window is an icon, the window status is determined to be an icon. Whether or not there is another window W2 above the window W1 can be determined by whether or not the identification number is registered in the upper window information 85 of the window management table.

Next, the registration processing of the identification numbers of the upper window information 85 and the lower window information 86 will be described. There are two processes, one for displaying the window at the top and one for deleting one window. By the way, the state of the window changes when a new window is created, when the icon is released, when the window is moved, when the window is changed to an icon,
There are six cases when the size of the window is changed and when the window is deleted. Here, when a new window is created and the icon is released, the process of displaying the window at the top may be performed. Further, when the window is changed to an icon and when the window is deleted, the window may be deleted. Further, when the window is moved or the size of the window is changed, the window may be deleted first, and then the window may be displayed at the top.

In the following, the process of registering the upper and lower window identification numbers when the window is displayed at the top,
FIG. 2 shows the process of deleting the identification numbers of the upper and lower windows when deleting the window and the window, respectively.
3 will be described with reference to the flowchart of FIG.

First, the case where the window is displayed at the top will be described. First, when the window is displayed at the top in step S191, it is then checked in step S192 whether the window displayed at the top and the other windows overlap. If there is an overlap between the window displayed at the top and other windows in step S193, the identification number of the window displayed at the top is registered in the upper window information of the window that overlaps with it in step S194, and The window identification number displayed at the top is registered in the lower window information of the lower window of the window displayed at the top. On the other hand, if there is no overlap in step S193, registration is not performed.

Next, the deletion of the identification numbers of the upper and lower windows when the window is deleted will be described. First, when the window is deleted in step S201, the identification number of the deleted window is deleted from the upper window information of the window lower than the window deleted in step S202, and the lower window information of the window above the deleted window is deleted. Delete the identification number of the window that was deleted from. Next, step S20.
The upper and lower window information of the window deleted in 3 is cleared.

As described above, when the window state is determined, the overlapping of windows is checked. To check the overlapping of windows, the following may be checked. That is, the upper left of the screen is the origin, the horizontal direction is the x-axis (rightward is positive), and the vertical direction is y-axis (downward is positive). If the coordinates of the upper left point of the window are (X _L , Y _L ), and the coordinates of the lower right point are (X _R , Y _R ), the coordinates of the lower left point are (X _L , Y _R ), and the coordinates of the upper right point are (X _R , Y _L ). When there is overlap, any of the four corners of the window exists in the display area of another window. Therefore, the coordinates of any of the four corners of the window are (X,
Y), and whether or not there is an overlap with the above-mentioned window may be checked by checking whether X _R ≦ X ≦ X _L and Y _R ≦ Y ≦ Y _L are satisfied. Also, the determination as to whether it is above or below depends on the content of the window operation.

For example, when a new window is displayed, it is determined that the newly displayed window is upper and the already displayed window is lower. Similarly, with respect to the window from which the icon has been released, it is determined that the window from which the icon has been released is on the top and the window already displayed is the bottom.

Although the origin of the window position is the upper left point of the screen here, the present invention is not limited to this, and the present invention can be applied to the case where an arbitrary point is the origin.

Further, only the last input command name is supposed to be stored in the execution command information 82 of this embodiment, but as the data of the execution command information, there is a flag indicating the execution status of the command. By also having the information, the operating system of the workstation notifies the window management section 49 that the process of the execution command has been completed, so that the execution status of the command can be displayed in the window information display field. This allows the operator to know whether or not the command execution is completed.

FIG. 13 is an example of displaying a window based on the flowchart described above. Here, when the position where “make” is displayed in the command display area 28 is clicked with the mouse, the corresponding window 21 is displayed at the top based on the flowcharts of FIGS. 18 and 19. At the same time, the window 21 becomes "T" and the window 25 becomes "H" in the status display. This is shown in FIG.

According to the display method described above, the target window can be displayed at the top by simply specifying the execution command name display field on the screen. In order to display the window 21 at the top as described above, it is sufficient to click the command name "make" with the mouse.

However, in order to display the window 21 at the top by the conventional method, for example, the windows 25, 24, 2 are displayed.
It is possible to display the window 21 at the top by moving or iconifying 3 so that a part of the window 21 is displayed. Also, if you want to see the execution result of make, and if you do not know where that window is, you can display the target window at the top by simply specifying the command name display area. It is necessary to check the display contents in order from the upper window, and move or iconify if they are not the desired windows.

As described above, conventionally, it was difficult to display the target window at the top by one operation, but according to the present embodiment, the target window is displayed at the top by one operation. It is possible to display.

[0114]

As described in detail above, according to the invention described in claim 1 or 2, an application program is executed by another workstation on the network and a new window created by the application program is being used. When displaying on the display screen of the workstation, even if the display position of the new window is completely outside the display screen because the application program does not consider the display screen at all, at least part or all of the display position of the window is displayed. Can be modified to be displayed on the display screen, so that a new window can always be displayed on the display screen.

As a result, since the display screen is small, the window may completely protrude from the screen, making it impossible to execute the application program or viewing the execution result of the application program. It becomes possible to avoid it.

On the other hand, according to the third aspect of the present invention, even if many windows are hidden underneath or displayed as icons, the windows are moved by trial and error to set the target window. You can display the target window at the top with a single operation without searching.

Further, several windows are opened by the command display area, and it is possible to easily grasp what kind of command is executed in each window. As a result, it is possible to reduce waste such as redundant execution of commands and improve work efficiency.

Further, by extracting the process identification number of the command executed in each window and inquiring the process management section of the operation system about the state of the process of the identification number for every fixed time, the command is executed in the command display area. It is also possible to display a mark indicating whether or not the process is completed.

Thus, the operator can grasp whether or not the execution of the command is completed. When the execution is completed, the window in which the execution is completed is designated by designating the command display area of the command in which the execution is completed by the mouse. You can display it at the top and immediately enter the next command. With the above, there is also an effect that work efficiency is improved.
