Description

The present invention relates to a method for efficiently moving ruled lines in a table displayed on the screen of an information processing device such as a computer or a word processor.

<Prior Art> Conventionally, when editing a complicated table that includes characters and figures and is separated by vertical and horizontal ruled lines that are not in a grid pattern by a word processor, for example, the ruled line editing function is used for the frame of the table and each frame is edited. The entire table is constructed using the character and figure editing functions for the letters and figures inside.

<Problems to be solved by the invention> However, when moving the ruled lines in the table by the above-mentioned conventional editing method, after specifying the ruled line creation mode and entering this mode, the area is specified by the desired ruled line or cursor or mouse. After moving the ruled line by selecting with, and specifying the position of the move destination, you must re-edit the characters and figures in the table that protrude from the ruled line or straddle the ruled line. for that reason,
If a plurality of ruled lines on a straight line are to be moved in the same way, there are disadvantages that it takes a long time to move and the operation of a cursor or the like becomes complicated due to movement and re-editing of characters and figures.

Therefore, an object of the present invention is to use a rectangular information memory that stores, for each block, the coordinates, dimensions, and mutual geometrical relation of each block, in addition to the character and graphic data in each block separated by ruled lines. Thus, it is possible to provide a table ruled line moving method capable of easily and efficiently moving a plurality of ruled lines designated in the entire range of the table or within the range of the selected block in various modes.

<Means for Solving the Problems> In order to achieve the above object, the ruled line moving method of the table of the present invention refers to and changes the contents of the memory according to the program by the CPU based on the information input from the input unit. While generating display data while displaying the display data as a table including characters and graphics on the display unit,
A content information memory that stores the character and graphic data of each block delimited by the vertical and horizontal ruled lines in the above table for each block, the data type of each block, the starting point coordinates, the width, the height, and the rectangle of the adjacent block. Pointer to information memory,
Chain pointer to the rectangular information memory of the block related to movement, rectangular information memory that stores the data pointer to the corresponding area of the above content information memory for each block, and the x and y coordinate values from the origin of the above table are gradually increased When I did
Specify the block index memory that sequentially stores the pointer to the rectangular information memory of the first block that appears next, and the ruled lines that should be moved in a straight line within the entire range of the above table or the range of the selected block, and specify the specified ruled line. After selecting the movement mode from one of the first to third modes, the coordinate input means for determining the movement amount, and when the first mode is selected by this coordinate input means, the designated ruled line is closest to both sides thereof. When the second mode is selected within the range of the ruled line of, the specified ruled line and all the ruled lines before this ruled line are set to the third ruler within the range of the nearest ruled line behind the specified ruled line. When the mode is selected, the movement range setting procedure that makes it possible to move the specified ruled line and all the ruled lines behind this ruled line within the range of the nearest ruled line in front of the specified ruled line. And the rectangular information memory of the block before and after the ruled line specified by the coordinate input means and the intermediate block straddling the specified ruled line by the pointer chain of the front block, the back block, and the intermediate block, respectively. Pointer setting means for setting a chain pointer in the rectangular information memory to be connected, and rectangular information connected to each other by the front block and rear block pointer chains based on the movement amount determined by the coordinate input means when the first mode is selected. Pointer and block index in rectangular information memory that is connected to each other in the subsequent block pointer chain after updating and redrawing the data pointer of the start point coordinate, width and height in memory and the corresponding information memory area Move the memory pointer based on the positional relationship between the blocks after moving the ruled lines. When the second or third mode is selected, the starting point coordinates, width, and height data in the rectangular information memory connected to each other by the front block, rear block, and intermediate block pointer chain, and the corresponding area of the content information memory It is characterized in that it is provided with a memory updating means for updating and redrawing the data pointer to, and moving the ruled line in a desired movement mode and movement amount by the coordinate input means.

<Operation> Characters of each block in the table displayed on the screen of the display,
The graphic data is stored in the content information memory, and the starting point coordinates, width, and height of each block and the data pointer to the content information memory are stored in the rectangular information memory for each block.

Now, when the coordinate input means specifies a ruled line to be moved on a straight line within the entire range of the above table or the range of the selected block, and the movement mode is selected, the movement range setting means causes the movement range setting means to select the first mode. The ruled line specified at that time is within the range of the nearest ruled lines on both sides of the ruled line specified when the second mode or the third mode is selected, and all ruled lines before or after this ruled line are specified. While allowing movement within the range of the nearest ruled line on the rear side or the front side, the pointer setting means respectively sets the rectangular information memories of blocks before and after the specified ruled line and an intermediate block straddling the ruled line. Is set in the rectangular information memory in order to connect with the pointer chains of the front block, the rear block, and the intermediate block.

Next, when the amount of movement of the ruled line which is movable within the above range is determined by the coordinate input means, the memory updating means, based on the above movement amount, selects the previous block and the subsequent block pointers when the first mode is selected. Rectangle connected to each other by a chain. After starting point coordinates, width, and height data in the information memory and the data pointer to the corresponding area of the content information memory are updated and redrawn, a rectangle connected to each other by the post block pointer chain. The pointer in the information memory and the pointer in the block index memory are updated based on the positional relationship between the blocks after the ruled line is moved, and when the second or third mode is selected, the previous block, the subsequent block, and the intermediate block pointer chain are respectively updated. Correspondence of start point coordinates, width, height data and content information memory in rectangular information memory connected to each other To update the data pointer to that area to re-draw. Thus, the ruled line designated on the screen by the coordinate input means is quickly moved in the selected movement mode and the desired movement amount, and the characters and figures in the block related to the movement are also automatically edited. .

<Examples> Hereinafter, the present invention will be described in detail with reference to illustrated examples.

FIG. 1 is a block diagram showing an embodiment of a word processor adopting the ruled line moving method of the table of the present invention. According to the table block generation program 6a of the program memory 6 by the CPU 1 based on the information input from the key input device 2, this word processor refers to the table block information memory 7a of the data memory 7 and changes the table block information while changing the table block information memory 7a. The generated data is displayed as a table composed of a plurality of blocks separated by vertical and horizontal ruled lines on the display device 5 through the display memory 4, while the characters in the program memory 6 and the character and graphic data are generated according to the graphic generation program 6b. Is generated, stored in the content information memory 7b of the data memory 7, and displayed via the display memory 4 in the plurality of blocks on the screen of the display device 5.
Further, in the word processor, a ruled line to be moved on a straight line within the entire range of the table displayed on the screen of the display device 5 or the range of the selected block is designated, and the designated ruled line movement mode is set to the first mode. A coordinate input device 3 such as a mouse for determining the amount of movement after selecting one of the third modes is provided.

FIG. 3 shows the details of the data memory 7, and the table block information memory 7a stores the structural information of each block of a to d displayed on the screen as shown in FIG. 2 for each block. Rectangular information memories 11a to 11d, a block index memory 12 for storing the arrangement order of blocks with respect to the origin (x1, y1) in the table of FIG. 2 as an order of pointers to the rectangular information memory, and the coordinate input device. Front side of the ruled line specified by 3 to move (left side if vertical ruled line,
A block selection information memory 13 for storing a pointer (c) to a rectangular information memory of a block in the case of a horizontal ruled line) is provided. On the other hand, the content information memory 7b is provided with the character and graphic data as the content of each block for each block. Store.

In each of the above rectangular information memories 11, the data type (character or graphic) of the corresponding block in order from the top, the starting point coordinates (x, y coordinates of the upper left corner), the width, the height, and the rectangle of the blocks connected to the bottom and the right. A pointer to the information memory, a chain pointer described later, and a data pointer to the corresponding area of the content information memory 7b are stored. Nil in rectangle information memory 11
Indicates that there is no pointer. The index memory 12 is divided into an x-part and a y-part, and the rectangular information memory of the block that appears first when the x, y coordinate values are gradually increased from the origin (x1, y1) in the table of FIG. Pointers to are stored in the x-part and the y-part, respectively. The rectangular information memory 11a, 11b, 11c,
Since the data type of 11d is character (TEXT) except 11b, katakana character data is stored in the area corresponding to 11a, 11c, 11d of the content information memory 7b as shown in the figure, and the data type is graphic (GRAPHIC The graphic data is stored in the area corresponding to the memory 11b.

Further, in the block selection information memory 13, in order from the top, a pointer to the block index memory 12 indicating the start position of the block group related to ruled line movement, and the starting point coordinates (x2, y2) of the block group (c, d). ), Block group width and height (w3, h3 + h4), block group end point coordinates (x2 + w3, y3 + h)
4) The total number of blocks in the block group (2) and the pointer (c) to the rectangular information memory of the preceding block are stored.

On the other hand, the CPU 1 of the word processor also serves as a moving range setting means, a pointer setting means, and a memory updating means. That is,
When the first mode is selected by the coordinate input device 3, the CPU 1 as the movement range setting means sets the specified ruled line within the range of the nearest ruled lines on both sides of the specified ruled line when selecting the second mode or the third mode. And all the ruled lines on the front side or the rear side of this ruled line can be moved within the range of the nearest ruled line on the rear side or the front side of the specified ruled line, respectively.
(See steps S5 to S8 in the figure). As a pointer setting means
When the ruled line L shown in FIG. 2 is designated by the coordinate input device 3, for example, the CPU 1 receives the rectangular information memory 11c of blocks c and d before and after the ruled line and an intermediate block b straddling the ruled line. Each of 11d and 11b is a front block, a rear block,
Chain pointers are set in the rectangular information memories 11c, 11d, 11b so as to be connected by the pointer chains of the intermediate blocks. In this example, unlike the examples in FIGS. 4 and 6, since there is one designated ruled line, there are no blocks before, after, and in the middle that are connected to each other by the above pointer chains, and there is no chain on the bottom left side of the rectangular information memory. The pointer is not set.

Further, the CPU1 as the memory updating means is the first selected
-When the coordinate input device 3 determines the movement amount of the ruled line that is movable within the range corresponding to the third movement mode (see step S13 in FIG. 7), the table shown in FIG. The _{first with} vertical ruled lines L ₁ and L ₂ that are on a straight line in the entire range of
In the case of the mode, a rectangular information memory (11b, 11f; 11
(c, 11g) After starting point coordinates, width, height data and the data pointer to the corresponding area of the content information memory 7b are updated based on the movement amount and redrawn (see step S14 in FIG. 7). ), The pointer in the rectangular information memory (11c, 11g) connected to each other in the rear block pointer chain and the pointer of the block index 12 are based on the positional relationship between the blocks after the ruled line movement (see FIG. 4 (b)). Updated (see step S15 in FIG. 7) and in the second mode or the third mode in which vertical ruled lines L ₁ and L ₂ are designated as in FIG. 6 (b), the previous block, the next block, the intermediate block pointer Starting point coordinates, width, in rectangular information memory (11b, 11f; 11c, 11g; 11d; 11e) connected to each other by a chain,
The height data and the data pointer to the corresponding area of the content information memory 7b are updated based on the movement amount and redrawn (see steps S16 and 17 in FIG. 7). The fifth
In the figure (a), select blocks b and c and specify ruled line L ₁ ,
The case where the first mode is selected as the movement mode is shown.

A table ruled line moving method by the word processor having the above configuration will be described below with reference to the flowchart of FIG.

Now, it is assumed that the coordinate input device 3 specifies a ruled line to be moved in the table displayed on the screen of the display device 5 and selects the movement mode. Then, the CPU 1 first checks the moving mode in step S1, and if the moving mode is the first mode, proceeds to step S2 to check whether the specified ruled line is within the selected block area. If the movement mode is the second or third mode in step S1 and the ruled line specified in step S2 is outside the area of the selected block,
In step S3, the entire table is set as the selection area. Next, in step S4, the rectangular information memory in the selected area is checked, and the rectangular information memories of the blocks immediately before the specified ruled line are mutually preceded by the block pointer chain (prev),
The rectangular information memories of the blocks immediately after the ruled lines are connected to each other by the subsequent block pointer chain (post), and the rectangular information memories of the blocks straddling the ruled lines are connected to each other by the intermediate block pointer chain (midd).

Then, in step S5, the movement mode is checked again, and the first, second,
According to the third mode, the process proceeds to steps S6, S7 and S8, respectively, and examines how far the designated ruled line and the like can move to the front side and the rear side, respectively. That is, in step S6, the range up to the closest ruled line before and after the specified ruled line is set, whereas in step S7 the range up to the ruled line closest to the rear side of the specified ruled line is set, and in step S8 the above The range up to the ruled line closest to the front side of the ruled line is set respectively.

Next, in step S9 following step S6, input is performed by the coordinate input device 3, the moving range is checked, and if the cancel input is made in step S10, the process is stopped, and the moving destination, that is, the moving amount is determined in step S11. Until then, the input value is displayed on the screen in step S12. Then, if the movement destination is determined in step S11, it is compared with the initial position in step S13, and if it is not actually moved, the process ends. On the other hand, if it is actually moved, in step S14, the structure information in each rectangular information memory connected to the previous block pointer chain and the subsequent block pointer chain obtained in the previous step S4 is updated by the above movement amount and re-created. draw. Finally, in step S15, the pointer held in the rectangular information memory connected to the rear block pointer chain is corrected from the positional relationship with other rectangular information.
Further, the processing following the steps S7 and S8 is also the same as the processing of the above steps S9 to S13, and in the final steps S16 and S17, the structure information in the rectangular information memory connected to the intermediate block pointer chain is also stored. Only the above movement amount is updated and redrawing is performed. In this case, the positional relationship of each block is the same as that before the movement, and therefore the process is ended as it is. The process for moving the ruled line in the horizontal direction is also performed in the same manner as described above.

If the above ruled line moving process is illustrated on the screen, if the ruled line L ₁ is specified without selecting a block in the table as shown in FIG. 4A and the first mode is selected, the ruled line L ₁ is extended. A certain ruled line L _{2 is} also designated at the same time, and both ruled lines L ₁ and L ₂ can be moved in parallel to the left and right within the range of the nearest ruled lines L ₃ and L _{4 on} the left and right of the ruled line. As shown in (b), both ruled lines L ₁ and L ₂ are moved and displayed at the same time to the right, and the widths of the blocks b and f are widened to blocks b ′ and f ′.
The width of g is sandwiched to form blocks c ′ and g ′. Also, the fifth
When blocks b and c are selected in the table as shown in Fig. (A), ruled line L ₁ is specified, and the first mode is selected, only ruled line L ₁ is within the range of the nearest ruled lines L ₃ and L _{4 on} the left and right thereof. When the desired destination is determined, only the ruled line L ₁ is moved to the right and displayed as shown in FIG. 5B, and the width of the block b is widened to block b ′. Become. Furthermore, if the ruled line L ₁ is specified without selecting a block in the table as shown in FIG. 6A and the third mode is selected, the ruled line L ₂ is also specified at the same time, and the ruled lines L ₁ and L ₂ and the right side thereof are also specified. The ruled lines L ₃ and L ₄ in
If they can be moved in parallel to the left and right within the range of the nearest ruled line L ₅ on the left side and the desired destination is determined, FIG. 6 (b)
As shown in, the determinations L ₁ , L ₂ , L ₃ , L ₄ are simultaneously moved to the right and displayed, and the widths of the blocks b, d, and f are expanded and the block b ′,
It can be seen that d ', f'becomes, and the start positions of the blocks c, e, g are further moved to the right to become blocks c', e ', g'. The same applies to the case of moving the horizontal ruled line.

In these examples, when a block is enlarged or reduced by moving a ruled line, the content (character, figure) of the block is associated with a new area of the content information memory 7b by updating the data pointer in the rectangular information memory. So
Characters and figures on the screen do not straddle the ruled lines after moving or stick out. Therefore, it is not necessary to re-edit the contents of the block related to the movement of the ruled line as in the conventional case, and there is an advantage that the movement of the ruled line becomes efficient.

As described above, according to the above-described embodiment, the ruled line to be moved by the coordinate input device 3 in the table displayed on the screen of the display device 5 is designated together with the block as necessary, and the movement mode is simply selected. , CPU1 automatically moves the specified ruled lines etc. all at once while re-editing the contents of the block, so compared to the conventional method that requires complicated moving operation with the cursor or mouse and re-editing of the block contents. Thus, ruled line movement can be performed much easier and more efficiently.

Needless to say, the present invention is not limited to the illustrated embodiment.

<Effects of the Invention> As is clear from the above description, according to the ruled line moving method of the table of the present invention, the character and graphic data of each block in the table is stored in the content information memory of the information processing apparatus, and the rectangular information memory is stored. While storing the structural information including the geometrical correlation of each block, the coordinate input means specifies the ruled line to be moved, the movement mode and the movement amount, and the movement range setting means determines the movement range of the ruled line according to the movement mode. The pointer setting means connects the rectangular information memories of the front, rear, and middle blocks of the specified ruled line with each pointer chain, and the memory updating means appropriately sets the front, rear, and intermediate pointer chains according to the movement mode. Since the structure information in each connected rectangular information memory is updated and redrawn based on the above movement amount, the contents of the block are reedited such as the specified ruled lines. However, the ruled lines can be moved much more easily and efficiently than in the conventional method that requires a complicated moving operation using a cursor or the like and the re-editing of the block contents.
