Abstract

(57) [Summary] [Problem] In the conventional technique, it is not possible to efficiently compare both objects, one of which is hidden outside the screen by the scrolling operation and the other of which appears inside the screen. A method for controlling scrolling of a display screen by a computer, in which a display coordinate value of an area designated by an operator on the screen before the start of scrolling is increased or decreased according to the amount of scrolling of the screen to perform an operation. The area specified by the user is displayed at an arbitrary position on the screen to be scrolled.
For example, the display coordinate value of the icon designated by the operator is increased or decreased in the direction opposite to the scroll direction by the amount of scrolling, and the designated icon is displayed at the same position as before the start of scrolling the screen.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display screen control technique by a computer, and more particularly to a screen scroll control method suitable for improving the convenience of the user when scrolling the screen.

[0002]

2. Description of the Related Art In recent years, as a display interface for operating a computer, a character user interface (CUI: Character User Interface) has been used to provide a larger amount of information to an operator and to make the computer simpler. Operable image information type graphical user interface (GUI: Graphical U)
Ser Interface). That is, in this GUI, the user (operator) performs a visual and intuitive operation using not only characters but also the contents of the file called icons such as icons, patterns that represent the functions / work by figures, symbols, and the like. It is possible.

Objects on the GUI screen (here,
Operating system (OS: Operating)
Operations on characters, graphics, files, icons, etc., which are processed as image data in the desktop environment of System) are performed on a general multi-window (window; GUI, virtual screen having icons etc. inside at the time of display). , Which can have a coordinate system of a size larger than that of a display device), as instructed by information input from a coordinate input device such as a mouse as seen in an OS using a GUI of a format, and specifically, a plurality of Alternatively, it is possible to perform processing such as moving / copying / deleting by itself. still,
Regarding the GUI display technology, for example, Japanese Patent Laid-Open No. 5-21
As described in Japanese Patent Publication No. 0722, there is a technique for representing an object with a symbol (here, a marker / mark added to the object by an operator) to simplify the operation and display on a display device. is there.

However, such a GUI cannot satisfy all the intentions of the operator regarding the operation and visibility of the object. For example, on a screen using a GUI, an operation of scrolling the virtual screen vertically or horizontally to display the entire information that cannot be displayed on the screen is performed. At the time of operation, the selected object is scrolled out of the window due to scrolling. As a result, it is necessary to scroll back to the original position to see the selected object.

To compare objects,
You can divide the display area (window, etc.) and, for example, arrange objects one above the other, create another display area, arrange the objects at any position on the screen, or combine comparison objects. However, these techniques become complicated when the number of objects to be compared increases.

[0006]

The problem to be solved is that in the conventional technique, it is not possible to efficiently compare both objects, one of which is hidden outside the screen by the scroll operation and the other of which appears inside the screen. Is. An object of the present invention is to provide a screen scroll control method that solves the problems of the conventional techniques, improves the convenience of the user when scrolling the screen, and improves the operability of the GUI.

[0007]

In order to achieve the above object, a screen scroll control method of the present invention is (1) a display screen scroll control method by a computer, which corresponds to the screen scroll amount. The display coordinate value of the area designated by the operator is increased or decreased on the screen before the start of the scroll, and the area designated by the operator is displayed at an arbitrary position within the screen to be scrolled. Further, (2) a method of controlling scrolling of a display screen by a computer, wherein when the screen is scrolled, the display coordinate value of the area designated by the operator on the screen before the start of the scroll is scrolled by the scroll amount. The area designated by the operator is displayed in the same position as before the start of scrolling the screen by increasing or decreasing in the direction opposite to the direction. (3) In the screen scroll control method according to (1) or (2), the area designated in advance by the operator includes at least an icon in a window displayed by the graphical user interface. The display coordinate value of the area including the icon is increased or decreased according to the scrolling in the window.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, an object whose position is fixed on the screen by the operator as necessary does not change its position even if an event occurs that changes the position on the screen by scrolling. Absent. For example, an object placed on the screen may be an external program or OS.
When a symbol is added to an object using the symbol processing function provided as its own function and scrolling occurs in the window in which the object exists,
Fix the position of the object in the window so that it does not change. That is, after the operator designates an object to be fixed with a mouse or the like, a mark is added to it (marker), and the fixing processing function is called as necessary to fix the object at an arbitrary position on the screen.

Here, the marker is represented by a symbol that can be freely defined by the operator, and is managed in group units. Then, whether or not the object to which the marker is added is fixed on the screen can be determined in group units. In addition, to notify the operator of the object's fixed instruction status, etc., change the status of the symbol added to the object, or set a marking function separately prepared other than the window in which the object is displayed. This can be handled by changing the notation of the group symbol in the specified window (marking group window). Both, the state of fixed / display / selected,
It is expressed by color, form, action, etc., and provides the operator with information that can be clearly discerned on the screen.

Further, the effective range of fixing an object is less than or equal to the child when the correlation of objects is a hierarchical structure. That is, if the position of the parent is moved, the position on the screen is changed by the movement of the parent even if the fixed flag of the child is fixed. However, the positional relationship between parents and children is maintained. Also, when a child is fixed, its grandchild is also fixed in position. To fix an object on the screen at an arbitrary position, add a fixed processing routine to the scroll processing of the OS or application, and add fixed processing to the OS or the OS. If permitted, it is conceivable to hook the screen rewriting process, perform the scroll process for fixing, and then return the process to the OS.

Further, the marking function includes a collective processing as an additional function other than the fixed display of objects. This is a specific area on the screen (such as in a new window) for a selected group object of the same symbol.
In order to collect objects, there are technologies that use links and technologies that copy the objects themselves. In addition, it is possible to easily add a function of temporarily not displaying the marked object on the screen, and it is also easy for the operator to freely select the display / non-display of the marking symbol. it can. Then, all of these functions can be made to function independently regardless of the operating state of each function.

As described above, according to the present invention, the operator can scroll the screen while the desired object is fixed in position, and can operate and visually recognize the icon or the like arranged in the GUI window. Can be done efficiently. For example, when an operator tries to select multiple objects on a window when copying an object, the selected object will be scrolled out of the screen even if all the objects are not visible on the screen. Since it does not happen, you will not lose sight of the corresponding object. Further, when a plurality of objects, for example, a word processor, etc., are to be viewed while correcting a part of a document, fixing the object (here, a character string) is useful for efficient document creation.

An image storage device 2 such as an AM, a display device 1 for displaying and outputting information in the image storage device 2, and an output device 6 such as a laser printer for outputting programs and data on paper are connected.

The display device 1 outputs a GUI composed of graphical windows and icons. When the operator gives an instruction using the mouse from the input device 4,
The control device 3 processes the information and modifies the graphic information in the image storage device 2. The information is immediately reflected on the display device 1, and the operator can check the result of the instruction given by him / her.

FIG. 3 is an explanatory diagram showing a GUI example displayed by the computer system shown in FIG. In FIG. 3, reference numeral 101 denotes a display area of the screen 100, and all information is displayed within this display area 101. Also,
102 and 103 are windows, and this window 1
A plurality of objects can be included inside 02, 103. Objects 104 to 111 are data, programs themselves, or icons for calling them. These objects 104-111
Is drawn in the windows 102 and 103 in the example of FIG. 3, but the actual GUI is not limited to this and may be arranged outside the windows 102 and 103.
Also, a GUI in which a window is included in the object
It is also conceivable that, for example, an interface in which a window hidden on the display is displayed on the screen when the object is activated by an instruction of the operator is also conceivable.

Reference numerals 112 to 114 are contents designated for each object, for example, display of a symbol representing a fixed display according to the present invention, and 121 is a function according to the present invention which the computer system in FIG. 2 has. It is a window in which various functions including are grouped into one window. Here, the window is named as a marking group, and the function selection buttons 115 and 117 and the symbols 116 and 11 are included.
8. Has group operation functions 119, 120 and the like. The function selection buttons 115 and 117 are assigned a function of changing the state. A scroll bar 122 is used to scroll the window 102. These object windows are actually

FIG. 4 is a diagram of the object in FIG.
5 is an explanatory diagram showing an example of a storage form in the storage device in FIG.
As shown in FIG. 4, each object in FIG.
In the storage device 5 in FIG. 2, the object table 40
Is stored as This object table 40
Above, the name of the object placed on the screen, the name of the window to which it belongs, the coordinate value in the window, the ID number for identifying the group specified by the operator, the display / non-display flag, and the fixed / movable flag. Etc.

FIG. 5 is an explanatory diagram showing an example of the storage form of the window in FIG. 3 in the storage device in FIG. As shown in FIG. 5, the window in FIG. 3 is stored as the window table 50 in the storage device 5 in FIG. On this window table 50, an ID number "window ID" for identifying the window
There is a window name “window name”, a window coordinate value “window coordinate” on the screen, and the like.

For simplicity of explanation, the window and object tables are separated as shown in FIGS. 4 and 5, but in an actual system, windows and objects are managed on the same table. It is also possible to do so. For example, the window name on the object table in FIG. 4 is the upper object name, or
If it becomes an ID number, the window can be regarded as an object and can be easily realized. Further, other forms of tables for internally managing objects are conceivable, but since the functions according to the present invention can be exhibited regardless of the forms of the tables, detailed description will not be given in the present embodiment.

FIG. 6 is an explanatory diagram showing an example of the configuration of a table defining the grouping of each object in FIG. In this example, the objects are grouped in the symbol group table 60 based on the symbols associated with the respective objects, and this symbol group table 60 uses I for identifying the groups.
It is composed of a D number "group ID", data "symbol" of the symbol itself, and link information "symbol display / non-display" for each symbol.

The operation of the computer system shown in FIG. 2 according to the present invention will be described below with reference to FIGS. 1 and 7 to 13. FIG. 7 is a flowchart showing the flow of the entire processing including the processing according to the present invention of the computer system in FIG. In FIG. 7, there is shown from the occurrence of the operator's input to the process of scroll processing on the screen particularly related to the present invention.

OS having a GUI desktop environment
Is in a state of waiting for an instruction until the operator performs some operation, as shown in steps 151 and 152 in FIG. 7, and when an input occurs, the process proceeds to the next step. The input from the operator is generally processed in the form of an interrupt, and the function corresponding to each interrupt type operates. For example, scroll interrupt
This occurs when the scroll bar 122 in FIG. 3 is selected with the mouse and moved up and down. The amount of this scroll is
It is calculated based on the amount of time the mouse button is pressed and the amount of movement of the scroll bar, and is reflected on the screen.

In the example of FIG. 7, distribution by interrupt type corresponds to step 153, and after a series of processing (steps 154 to 162) corresponding to each distribution result is completed, screen rewriting (rewriting) in step 155 is performed. After drawing)
It returns to the waiting state of steps 151 and 152 again. Further, step 154 after step 153 is a function selecting process for operating a symbol added to an object. Here, based on the instruction of the operator, "end",
Processing such as “display / non-display”, “fixed / movable”, “aggregate”, “new group”, and “deleted group” is sorted.

For example, in step 156, "display /
The process for "non-display" is a function of displaying or hiding the marked object or the marking symbol itself on the screen. Specifically, when "display" of the symbol status display 115 in FIG. 3 is selected with a mouse cursor or the like, the processing shown in detail in the flowchart of FIG. 8 is performed.

FIG. 8 is a flow chart showing a detailed example of the process A in FIG. When the “display” (function to change the state) of the symbol state display 115 in FIG. 3 is selected by a mouse cursor or the like, first, in step 210, the operator is asked whether the state or the symbol is to be changed. Select. If it is the object whose state is to be changed, the process proceeds to step 211, and FIG.
The group ID to be processed is extracted by referring to the symbol group table 60 in. And step 2
12, the object table 40 in FIG. 4 is referred to, and for all the records that match the group ID extracted in step 211 (step 219), the process proceeds to step 214, depending on the state of the “display” / “non-display” flag. , "Non-display", go to step 215, "display"
If so, the process proceeds to step 216.

At step 215, the display flag is changed from "non-display" to "display", and at step 216, it is changed from "display" to "non-display". Finally, in step 217, the record in the object table is updated. Incidentally, at the time of the redrawing process of step 155 in FIG.
The object that has been "hidden" is not written to the screen, so the corresponding object is not displayed on the screen. On the contrary, the object which has been “displayed” is displayed on the screen.

If the symbol selected in step 210 is a symbol, the "display" / "non-display" flag of the symbol is changed in step 213 for the corresponding symbol in the symbol group table 60 of FIG. And
In step 218, the corresponding record in the symbol group table is updated. In this case, step 15 in FIG.
At the time of the redrawing process of No. 5, the corresponding symbol which has become "non-display" is drawn on the screen. On the contrary, the symbol changed to "display" is drawn on the screen.

Next, the process B in step 157 in FIG. 7 will be described. Step 157 in FIG. 7
The "fixed / movable" indicated by is a flag process particularly related to the scroll control of the present invention, and is for keeping the display coordinate position of only the corresponding object when the window in which the marked object is placed is scrolled. Specifically, the symbol status display 115 in FIG.
When "fixed" is selected with a mouse cursor or the like, the processing detailed in the flowchart of FIG. 9 is performed. The processing operation in FIG. 9 will be described below.

FIG. 9 is a flowchart showing a detailed example of the process B in FIG. When “fixed” (the function for changing the state) of the symbol state display 115 in FIG. 3 is selected with a mouse cursor or the like, first, in step 220, referring to the symbol group table 60 in FIG.
Extract the group ID. Then, the process proceeds to step 222, the object table 40 in FIG. 4 is referred to, and the process proceeds for all the records that match the group ID extracted in step 220 (step 22).
7).

In step 223, based on the state of the fixed flag on the object table 40 of FIG. 4, if "fixed", the process proceeds to step 224, and if "movable", the process proceeds to step 225. In step 224, the fixed flag is changed from “fixed” to “movable”, and in step 2
At 25, "movable" is changed to "fixed". Then, in step 226, the object table 4 of FIG.
Update the corresponding record of 0.

Next, the process C in step 158 of FIG. 7 will be described. The "collection" process shown in step 158 in FIG. 7 is for collecting and displaying marked objects having the same symbol in one place. Specifically, the operator sets the group in FIG. When the "aggregate" of the instruction buttons 117 is selected with a mouse cursor or the like, the processing detailed in the flowchart of FIG. 10 is performed. The processing operation in FIG. 10 will be described below.

FIG. 10 is a flowchart showing a detailed example of the process C in FIG. When "set" of the group set instruction button 117 in FIG. 3 is selected with a mouse cursor or the like, first, in step 230, the symbol group table 60 of FIG.
Is extracted. In the next step 231, a new window C is created for displaying the objects after the assembly. FIG.
In the example on the window table 50 in FIG.
(3) is obtained. Next, in step 232, the object table 40 of FIG. 4 is referred to, and the set process is performed on all the records that match the group ID extracted in step 230 (step 234).

That is, in step 233, the window ID is the ID newly created in step 231.
(3) is used to add to the object table 50 of FIG. At this time, it is assumed that appropriate coordinate values are obtained by the coordinate function of the OS desktop environment.
After that, in the redrawing process in step 155 of FIG.
A new window C is displayed on the screen, and the assembly process ends. A specific example of such a grouping process will be described with reference to FIGS.

FIG. 16 is an explanatory diagram showing an example of a screen before the process C in FIG. 7, and FIG. 17 is an explanatory diagram showing an example of a screen after the process C in FIG. 16 and 17 show a transition example of the screen based on the processing of the processing C in FIG. 7, and in the case where the set processing is performed on the symbol 509 indicated by “black circle” in FIG.
Object (a1) 502, Object (b1) 5
11 will be the set target. Then, when the operator selects the button 510 for instructing the gathering in the group, the operation described in FIG. 10 is performed, and the screen changes to the screen shown in FIG. That is, in the screen after the assembly in FIG. 17, a new window (C) 534 is created, and an object (a1 ′) 532 and an object (b1 ′) 533 are displayed on the virtual screen.
Has been copied. In this example, the object is copied to the new window by the set process, but the object can be moved.

Next, the process D in step 159 of FIG. 7 will be described. The "new group" process shown in step 159 in FIG. 7 is to add a new symbol to the symbol group table. Specifically, when the operator selects the group symbol creation 120 in FIG. The processing whose details are shown in the flowchart is performed. The processing operation in FIG. 11 will be described below.

FIG. 11 is a flow chart showing a detailed example of the process D in FIG. When the group symbol creation 120 in FIG. 3 is selected, first, step 240
Then, start the new group creation task and enter the required information from the operator. Here, it is necessary to input a symbol, and the operator prepares and uses a bitmap of symbols or the like, animation data, or the like in advance or during this work. Then, in step 241, a new record is added to the symbol group table 60 of FIG. 6, and a new ID is assigned with the symbol additionally created in step 240. In the example of FIG. 6, the new ID is (3) as indicated by 31.

Next, the process E in step 160 of FIG. 7 will be described. The "deletion group" process shown in step 160 in FIG. 7 is to delete the symbols registered in the symbol group table. Specifically, the operator deletes the group symbol 11 in FIG.
When 9 is selected, the processing detailed in the flowchart of FIG. 12 is performed. The processing operation in FIG. 12 will be described below.

FIG. 12 is a flow chart showing a detailed example of the process E in FIG. When the group symbol deletion 119 in FIG. 3 is selected, first, step 250
Then, the group deletion task is started, the operator selects the symbol to be deleted, and the corresponding group ID on the symbol group table 60 of FIG. 6 is extracted. After the deletion symbol is determined, in step 251, the term of the group ID on the same record as the group ID extracted in step 250 from the object table 40 of FIG. 4 is rewritten to null (no value). Then, in step 252, the record processed in step 250 in the symbol group table 60 of FIG. 6 is deleted. As a result,
By the redrawing process in step 155 in FIG. 7, the symbol is erased from the screen.

Next, the process F in step 161 of FIG. 7 will be described. The "scroll process" shown in step 161 in FIG. 7 is a scroll having the processing system according to the present invention, and details are shown in the flowchart of FIG. 1 when the input interrupt generated in step 152 in FIG. 7 is the scroll process. Perform the processing that is performed. The processing operation in FIG. 1 will be described below.

For example, when the operator selects the scroll bar 122 in FIG. 3 and moves the virtual screen up,
As shown in the flowchart in FIG. 1, a series of scroll-related processing is executed. First, step 260
Then, a process for checking in which window the scroll is occurring is executed, and the window ID is extracted from the window table 50 in FIG. It should be noted that this processing uses a function that is standardly provided in an OS having a GUI.

Next, in step 261, the movement amount of how much the virtual screen of the scrolled window has scrolled is calculated. Also for this processing, O with GUI
The function that S has as standard equipment shall be used. Further, in step 262, the object table 40 of FIG. 4 is referred to, and the scroll processing according to the present invention is performed for all the records that match the window ID extracted in step 260 (step 265).

That is, first, the state of the fixed flag is determined by the branching process in step 263. If the state of the fixed flag is "movable", the coordinate value is not updated,
If it is “fixed”, the process proceeds to step 264. In step 264, the movement amount calculated in step 261 is subtracted from the coordinate value, the coordinate value on the record is changed, and the record is updated. By this processing, it is possible to realize processing that does not apparently change the coordinate position of the window for the object whose redrawing flag is "fixed". A specific example of such scroll processing according to the present invention will be described with reference to FIGS. 14 and 15.

FIG. 14 is an explanatory diagram showing an example of a screen before the processing by the process F in FIG. 7, and FIG. 15 is an explanatory diagram showing an example of a screen after the processing by the process F in FIG. 7. 14 and 15 show a transition example of the screen based on the processing of the processing F in FIG. 7. As a premise of the description, the object coordinates of the object table 40 in FIG.
It is assumed that the coordinates of the windows 102 and 103 in FIG. 3 are represented on the virtual screen. Hereinafter, FIG.
Description will be made assuming that scrolling has occurred in the window 301 in FIG.

In FIG. 14, of the three objects displayed in the window 301, the objects (a1) 302 and 303 (a2) have already been given symbols "black circles" and "diamonds", respectively. . The "black circle" symbol indicates the marking group window 307.
As indicated by the state notation of the symbol 309 inside, the state is “fixed” or “displayed”. The “diamond” symbol is in the “movable” and “display” states, as indicated by the state notation of the symbol 310 in the marking group window 307.

Although the object (a4) 304 exists on the virtual screen in the window 301, it is not displayed on the screen because it is outside the display area of the window 301. Here, the operator operates the scroll bar 3
When 05 is selected and the virtual screen is moved up, the series of scroll-related processing shown in the flowchart in FIG. 1 is executed, and as a result, the screen changes to the screen shown in FIG.

In the screen example shown in FIG. 15, the object (a
2) 303 is the symbol 310, that is, the state of the “diamond” symbol is “movable”, so that it is scrolled out to the position shown as the object (a2) 323 in FIG. 15 after scrolling. On the other hand, the object (a4) 304 located on the lower side outside the display area of the window 301 in FIG. 14 is in the position shown as the object (a4) 324 in FIG. 15 after scrolling, and within the display area of the window 322. It is displayed.

Further, the object (a
1) The state of the symbol “black circle” added to 302 is “fixed”, and therefore the object (a1) 325 is also at the same position as the object (a1) 302 in FIG. 14 in FIG. 15 after scrolling. In this way, if the state of the symbol added to the object is "fixed",
It can be seen that the object retains its coordinate position on the window during scroll processing. As a result, the operator displays the object (a
1) 325, that is, the object (a1) 302 and the object (a4) 324 can be compared side by side.

Next, the process G in step 161 of FIG. 7 will be described. The “marking process” shown in step 161 in FIG. 7 is to add a symbol to an object or to release a symbol added to an object. For example, the operator may change the symbol on the marking group window 121 in FIG. 116, 11
When 8 is selected, the process of "addition" operates, and
Object (a1) 104 and object (a
2) Marking objects with symbols, such as 105 and object (b2) 109, in the marking group window 1
In the case of dragging to 21, for example, the “cancel” process operates. Hereinafter, regarding such a "marking process", FIG.
4 will be described.

FIG. 13 is a flow chart showing a detailed example of the process G in FIG. When the symbol 116 in the marking group window 121 in FIG. 3 is selected, in the branch of step 270, since the symbol is selected from the marking group window, the process proceeds to “add”. In step 271, the group ID is extracted with reference to the symbol group table 60 of FIG.

Then, in step 272, it is confirmed whether or not the object is selected. If the object has already been selected by the operator, the process proceeds to step 274. If the object is not yet selected, the step is executed. In step 273, the operator is requested to select an object, and the object name to which the symbol is added is clarified. Here, selecting an object means a state in which the record position on the object table 40 of FIG. 4 that has the object name of the operation target is listed in the work buffer or the like.

When the selection of the object is completed in this way, in step 274, the group ID of the symbol extracted in step 271 is written in the item of the group ID of the record of the corresponding object name in the object table 40 of FIG. , Further, step 277
At, the record is updated and the process ends. afterwards,
By the redrawing process of step 155 in FIG. 7, a symbol is added to the object on the screen.

When an object with a symbol is first selected and dragged to the marking group window 121 in FIG. 3 or the like, the branch in step 270 is "released" because the object with the symbol is dragged to the marking group window. , The process proceeds. In this case, in step 276, the record of the object name dragged on the object table 40 of FIG. 4 is extracted, and the item of group ID is changed to “none”. Then, in step 277, the record is updated and the process ends. As a result, at the time of the redrawing process in step 155 in FIG. 7, the symbol added to the object is erased.

As described above with reference to FIGS. 1 to 17, in the screen scroll control method of this embodiment, the GUI
On the table that manages the objects on the screen with
As illustrated in the object table 40 of FIG.
Managed as shown in the symbol group table 60 of
Depending on the state, the object is "fixed" on the screen,
"indicate. Also, for grouped objects,
Symbols are added to the symbol group table 6 of FIG.
Manage with 0. The operation of the symbol group table 60 is provided by a tool, and information and an operation interface are provided to the operator in a form as shown in the marking group window 121 of FIG.

The operator does not change the position of the object to which the symbol for fixing the object on the screen is added, even if an event such as scrolling that changes the position on the screen occurs. As a result, when the operator wants to copy or compare the objects on the screen, it is possible to efficiently check the number of objects that cannot be displayed in the window. Further, it is possible to easily confirm that the operator has actually given an instruction to the computer, and the operator can easily carry out copying of objects and comparison work on the GUI.

The present invention is not limited to the embodiment described with reference to FIGS. 1 to 17, and various modifications can be made without departing from the spirit of the invention. For example, in the present embodiment, the scrolling of the window in which the object is fixed on the screen is performed by the marking tool, but it can be made to function as a part of the desktop function of the OS. Further, in the present embodiment, the object is controlled to be at the same position before and after scrolling, but by adding a correction value to the coordinate value, an arbitrary position within the same window, for example, Alternatively, the display may be controlled to be displayed at a predetermined position such as the upper right corner.
