Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information display processing apparatus for presenting information accompanied by line figures having structures such as tables and ruled lines.

0002

[Background Art] Generally, in word processors and personal computers, line figures such as tables and ruled lines are described using data representing the position and size of the line figure as a line figure independent of the information presented with the line figure. .

For example, the table structure is a set of line segments (line segment start point coordinates (Xs, Ys), line segment end point coordinates (Xe, Ye), or an outer frame rectangle (rectangle upper left point coordinates (X1, Y1)).
), the width and height (w, h) of a rectangle, and a set of line segments that divide the interior.

Furthermore, when there is a change in the information presented, data such as the position and size of tables, ruled lines, etc., which are provided as independent line figures, are changed each time. For example, if the font size or length of a string displayed inside a table changes, consider the correlation between changing the string attributes and table size data. However, they are processed separately.

[0005]

[Problems to be Solved by the Invention] Conventionally, line figures such as tables and ruled lines have been widely used as a means to help understand the ease of viewing and the semantic cohesion of the information presented with them, but when displaying them, Tables and ruled lines are presented as line figures independent of the information presented with them, and their relationship to the presented information is not described. Therefore, it is not possible to automatically change the positions and sizes of tables and ruled lines to optimal positions and sizes in response to changes in the presented information. That is, there is a problem in that it is necessary to separately perform the process of changing the information to be presented and the process of changing the tables and ruled lines.

[0006] Accordingly, the present invention makes it possible to describe the mutual relationship between line figures such as tables and ruled lines and information presented together with them. An object of the present invention is to provide an information display processing device having a function of automatically changing information according to changes in information.

[0007]

[Means for Solving the Problems] The present invention provides an instruction means for indicating a two-dimensional structure indicating a line figure and information within the line figure, and an instruction means for indicating a two-dimensional structure indicating a line figure and information within the line figure. A storage means for storing mutual relationships, a line figure based on the two-dimensional structure stored in the memory means, and a line figure based on the two-dimensional structure stored in the memory means, and the above information is displayed at a predetermined position within the line figure from the mutual relationships stored in the memory means. A display means for displaying a display, a change instruction means for instructing a change in the two-dimensional structure, and a display means for changing the display of a line figure on the display means in accordance with an instruction by the change instruction means, and a correlation stored in the storage means. The processing means is configured to display the above-mentioned information at a predetermined position within a line figure that has been changed using

[0008]

[Operation] The present invention specifies a two-dimensional structure indicating a line figure and information within the line figure, stores the specified two-dimensional structure and information together with their mutual relationships in a storage means,
A line figure based on the stored two-dimensional structure is displayed, and the display means displays the information at a predetermined position within the line figure based on the correlation stored in the storage means, thereby changing the two-dimensional structure. In response to the instruction, the display of the line figure on the display means is changed, and the information is displayed at a predetermined position within the changed line figure using the correlation stored in the storage means. This is what I did.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 shows the external configuration of a personal computer or word processor as an information display processing device of the present invention. That is, on the upper surface of the lower part 1 of the main body, a keyboard part 2 is provided, which is composed of various keys and used as a character/numeric data input device.
A liquid crystal display section 4 using an STN liquid crystal is provided inside the upper opening/closing section 3 which is rotatably connected to the lower section 1 of the main body.
D) is provided with an FD insertion port 6 into which the FD is inserted. The configurations of the keyboard section 2 and liquid crystal display section 4 are similar to those used in general word processors, personal computers, and the like. Further, a mouse 8 used as a coordinate input device is connected by a cable 7 connected to a connector (not shown) of the main body.

For example, the keyboard section 2 is used to input the contents to be written in a table, or to input the number of rows and columns of the table. Furthermore, the mouse 8 is used to move the cursor and to specify the start and end positions of ruled lines and the like constituting the table.

Next, the control circuit of the information display processing device is shown in FIG.
Explain using. That is, the control unit 11 controls the entire information display processing device. The control unit 11 stores the keyboard unit 2, the mouse 8, a main memory 12 that is composed of a ROM that stores control programs and a RAM that stores data, and the contents displayed on the liquid crystal display unit 4. display memory 13, and the FD
An FD reader/writer 14 is connected that stores data on the floppy disk FD inserted through the insertion slot 6 and reads data from the floppy disk FD. Next, the software configuration stored in the main memory 12 will be explained using FIG. 3. That is, an application program 21, a command interpretation section 22, a screen display processing section 23, a related parts processing section 24,
and a table data conversion processing section 25.

When the command interpreter 22 receives a screen display request from the application program 21, the command interpreter 22 interprets the screen display processor 2 according to the target component and the contents of the command.
3 and the related parts processing unit 24 for processing. The screen display processing section 23 has a display processing module for each type of screen component. This display processing module includes, for example, a "table" component display processing section 23a for a table, and a "table" component display processing section 23a for a character string.
A "character string" component display processing section 23b is provided.

The related parts processing unit 24 calculates the size of the area necessary for displaying mutually related screen parts described in the screen data 11, determines overlap on the screen, and determines the correct inclusion relationship and positional relationship. Finally, the screen display processing unit 23 selects the “table” component display processing unit 23a as a display processing module for necessary components, or the “character string”
A display request is output to the parts display processing section 23b. As a result, a desired screen display can be obtained. Related parts processing section 2
4 is provided with a "table" related parts processing section 24a for tables and a "character string" related parts processing section 24b for character strings.

The table data conversion processing unit 25 executes data conversion between table data of different formats. FIGS. 4 and 5 are
It shows the data structure of screen data including a table. The screen data 30 includes a screen ID 31, number of screen parts 32, screen position coordinates (X, Y) 33, screen size (width, height) 34,
and a screen parts list pointer 35 as a pointer to a list of screen parts constituting the screen.

Screen parts include line figures such as tables/rules, parts that process the display/change of character strings in a single line/multiple lines, and parts that process the display/selection of text/figure options. There are parts that control the machine interface. here,
"Table" and "" which is displayed as item information inside the table.
This will be explained using screen data having a character string as an example. Note that the content of the following explanation is the same for any combination of tables/ruled lines and character strings/numeric strings/choice processing.

The data indicated by the screen parts list pointer 35 includes a "character string" 40, a "table" 50, and other parts. All screen parts have a part number on the screen,
Part No. 41 of "Character string" 40, Part No. 41 of "Table" 50
51, respectively. Furthermore, all parts have their types 43, 53, part positions (x, y) 44, 54, and part sizes (width, height) 45, 55.

The "character string" 40 includes display attributes 46 such as highlighting, underlining, and rope display, the character font name 47 used for display, and the area required for display, that is, the component size 45. Character font information (width and height of the character font) 48 serving as basic data and a pointer 49 to character string data to be actually displayed are recorded. Furthermore, the "character string" 40 has a field of related part number 42 indicating the relationship with a table or the like.

The "table" 50 includes pointers 57 and 58 to table data that describes the table structure in the first and second formats, and when it has table data in the second format, the first and second table data. A flag 56 indicating whether the table structures obtained from the table data in the format are the same is recorded. Furthermore, “Table” 5
0 has a field for related part No. 52.

The first format of table data (table data 1: coordinate string description data) 60 always exists in the "table" component, and is
Table drawing software receives and displays table data in this format. The first format table data 60 is a set of graphic elements, that is, rectangles or line segments, and includes the number of graphic elements 61, a graphic element pointer 62, and each graphic element data 63, 6.
Consists of 4.

For rectangles, field 71 indicates that the graphic element type is rectangle, and the coordinates of the upper left point of the rectangle (X, Y
) 72, rectangle size (width, height) 73, line type 74, and line width 75. This rectangle constitutes the outer frame boundary line of the "table".

For line segments, a field 81 indicating that the graphic element type is a line segment, line segment starting point coordinates (Xs, Y
s) 82, line segment end point coordinates (Xe, Ye) 83, line type 84
, with a line width of 85. It is also possible to describe a table structure by combining rectangles and line segments, or it is also possible to describe a table structure as a set using only line segments.

The second format of table data (table data 2: structure description data) 90 may or may not be included depending on the "table" component, and is recorded as necessary. The table data 90 in the second format is a set of structural elements, and includes the number of structural elements 91, a structural element pointer 92, a related part data pointer 93, an outer frame line type 94, and an outer frame line width 95. The structural element of a "table" refers to a partial structure of a table structure that can be described as "m rows x n columns" (multiple rows, multiple columns).

The structure element 100 includes a pointer 10 to an array indicating the number of rows 101 making up the "table" and the height of each row.
2. Pointer 103 to an array indicating the line type of the line separating the lower limit of each row, Pointer 104 to an array indicating line width, Number of columns 105, Pointer 106 to an array indicating the width of each column,
Pointer 1 to an array indicating the line type of the line separating the right end of each column
07, a pointer 108 to an array indicating the line width.

For example, according to the first format, the table data describing the table structure for the table shown in FIG. (in this case, the number of graphic elements is 8), or (2) only line segments, that is, 11 line segments (in this case, the number of graphic elements is 11).

According to the second format, "1 row x 3 columns", "
Since it can be divided into structural elements of "2 rows x 4 columns", the number of structural elements 101 is "2", and the structure element pointer 102 indicates the storage position of two structural element data, "1 row x 3 columns" and "2", respectively. It can be described as a partial structure of "rows x 4 columns".

Note that the related parts data pointer 103 is
An array of data structures describing the relationships between the "Table" component and other components that are displayed as item information of the "Table" is shown.

For example, when displaying the table shown in FIG.
The character string “A”, which is item information, is displayed in three sections of “1 row x 3 columns”.
Since "BC", "CENTER", and "123" are displayed, the related parts data (array) consisting of (related part number 111, related part display position 112) is (part N of "ABC").
O, left end) (“CENTER” part number, center) (“
123" (right end).Next, we will explain the case where a new table is created and displayed using the structure of the screen data.The content of the following explanation is about creation,
They may be selected or used in combination depending on the structure of the table to be displayed.

When the table structure is described as a structure of "n rows x m columns," table data 90 in the second format is created, and the table data conversion processing unit 25 converts this into a table in advance before display processing. A pointer 57 to the second format table data that is converted into the first format table data 60 by performing data change processing and manages the "table" parts, respectively;
The pointer 58 to the first format table data is set. Further, a match mark is recorded in the flag 56 indicating that both the first and second format table data exist and that the table structures obtained from both table data are equivalent at this point. When displaying, the first table data 60 is sent to the "table" component display processing section 23a.

[0030] If you want to create and display a table with a structure in which only a part of the table is subdivided, an arbitrary number of graphical elements can be added to the table data 60 of the first format obtained by the above method. Data (rectangle 63, line segment 64) is added, the number of graphic elements 61 is updated, and a mismatch mark indicating that the table structures obtained from the first and second format table data do not match due to this addition. is recorded in the flag 56. When displaying, the table data 60 in the first format is sent to the "table" component display processing section 23a.

When the table structure is described as a set of graphical elements (rectangles, line segments), first format table data 60 is created and set in the pointer 57 to the first format table data. . Furthermore, a mark indicating that only the first format table data 60 exists is recorded in the flag 56. When displaying, this first format table data 60 is sent to the "table" component display processing section 23a.

When only table data 60 of the first format exists, creating and displaying a table having a structure in which only a part of the table is subdivided is possible by creating and displaying an arbitrary number of graphic element data (rectangles 63
, line segment 64). Next, the case where the table structure is changed and displayed will be explained using FIGS. 6 and 7.

[0033] When there is table data 60 in the second format that describes the table structure as a structure of "m rows x n columns", it is extremely difficult to change this to a structure of "m' rows x n'columns". It can be easily achieved. That is, the number of rows 101 and the number of columns 105 of the table data 90 in the second format are changed, the table data change processing unit 25 obtains the table data 60 in the first format, and the first , a pointer 57 to the table data in the second format
, 58 may be updated. The table data change processing unit 25 generates table data 60 in the first format corresponding to the given table data 90 in the second format by converting the table data.

(1) When the number of rows 101 and the number of columns 105 increase, the given second format table data 90
Height of each row 102, partition line type 103 of each row, partition line width 104 of each row, width 106 of each column, partition line type 10 of each column
7. The value of the last element of the array of partition line width 108 in each column is adopted as the default value. When a number matching the number of rows and the number of columns is specified in the second format table data 90, this is used to generate the first format table data 60.

(2) When the number of rows 101 and the number of columns 105 decrease, the height 102, partition line type 103, and partition line width 10 of each row in the given second format table data 90 are reduced.
4. Width of each column 106, partition line type 107, partition line width 108
Adopt the number of values that match the number of rows and columns from the beginning of each array. When a number matching the number of rows and the number of columns is specified in the second format table data 90, this is used to generate the first format table data 60.

For a table having a structure in which only a part of the table is subdivided, specific information is added to the table data 60 in the first format obtained by converting the table data 90 in the second format. Since graphic elements (rectangles, line segments) have been added and a discrepancy mark indicating a discrepancy between both table data is recorded in the flag 56, the table data exchange processing unit that has been given the table data 90 in the second format converts the added graphic element (rectangle, line segment) into table data 60 in the first format while ensuring that the connection relationship is maintained as long as the end point of the added graphic element (rectangle, line segment) is on another line graphic.

Further, when the application program 21 supplies the screen display processing unit 23 with a command to move the display position of the “table”, the “table” component display processing unit 23a moves the “table” component position (X, Y). 54 to reflect this on the screen display. At the same time, the related component processing unit 24 checks the flag 56, and if table data of the second format exists, refers to the table data pointer 58 of the second format,
Check the related parts data pointer 93.

[0038] When parts that are mutually related to the "table" are described, the parts positions (X, Y) 44 of the related parts are also determined based on the related parts display position 112 of the related part No. 111. Change this to reflect this on the screen. Through this series of processing, the command for display position movement requested by the application program 21 for the "table" component causes the same display position movement to be executed for the item information of the table.

[0039] If the parts are not related to each other even if they are displayed overlapping each other on the screen, the above effect can be nullified by canceling the description as related parts data. Can be done.

Further, when the application program 21 supplies the screen display processing unit 23 with a command to change the font name 47 of the "character string" component, which is item information in the table, or the character string data itself, the "character string" The component display processing unit 43b changes the font name 47 of the "character string" component, the character string data pointer 49, and the character string data itself,
This will be reflected on the screen display.

At the same time, the related component processing unit 24 checks the related component number 42 of the "character string" component, and if another "table" component is described as a related component, its "
The related parts data pointer 93 is checked based on part number 51 of the "table" part, and the size of the section in the "table" that includes the "string" part that is the output target of the change display command is that of the "string" part. Determine whether the area size is sufficient for display.

[0042] If the mutual relationship between a "character string" and a "table" is described, and the size of the section within the "table" is not large enough to display the "character string" part that is item information, "table"
Change the data and continue determining the related parts. Until all parts satisfy the mutual relationship description, i.e.
The size determination is repeated until it is confirmed that all parts can be displayed within the specified section of the "table", and the final screen display processing is requested to the related parts processing unit 24. A later display screen is obtained.

As mentioned above, when changing the attributes (font size, string length, string itself) of item information such as character strings displayed inside a table, the correspondence between the table and item information is changed. It calculates the size of the area required to display item information based on the described data structure, automatically changes the data representing the position and size of the table to the optimal value, and even changes the shape of the table that is already displayed. This is done automatically.

[0044] With this, it is possible to describe the mutual relationship between line figures such as tables and ruled lines and the information presented together with them. It can be automatically changed in response to changes.

[0045]

[Effects of the Invention] As detailed above, according to the present invention,
The mutual relationship between line figures such as tables and ruled lines and the information presented with them can be described, and the position and size of mutually related table structures and character strings can be changed automatically while maintaining the relationship. An information display processing device capable of processing can be provided.
