Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a table display control device, a table display control method, and a storage medium storing a table display control program.
[0002]
[Prior art]
Scrolling is an indispensable function for displaying software such as editors, word processors, and spreadsheet software. Scrolling is a function that moves the display screen up, down, left, and right to display the rest when data cannot be displayed on one screen of the display. That is, when the text is a plurality of pages in an editor or word processor, or in the case of a spreadsheet software, when the “worksheet” is composed of a plurality of rows and a plurality of columns, the user can perform a desired scroll operation. You can browse rows and desired columns.
[0003]
The scroll function is also used to display a form such as an accounting operation. As the form, a “bundling table” having a hierarchical structure as shown in FIG. 32 is known. This figure is a diagram showing a “product sales record table” which is an example of the table. In the case of merchandise, one merchandise is classified into a plurality of categories, and each category is expressed in a hierarchical structure such that each category is classified into a plurality of actually sold merchandise. A summary table represents such a hierarchical structure in a tabular form.
[0004]
The product sales record table 200 shown in the figure is divided into a fixed area 210 that is an area not subject to scroll operations and a scroll area 220 that is an area subject to scroll operations, and can be scrolled only in the scroll area 220. ing. That is, the fixed area 210 includes items related to products expressed in a hierarchical structure (product items such as “calculator”, “category item items” such as “DIARY”, and product identification numbers such as “0112123 SF-4400” and the like. The scroll area 220 includes various attribute data (“sales amount”, “number of sales”, “number of purchases”, “gross profit”, “gross ratio” of each data item in each row of the fixed area. , “Inventory quantity”, “Inventory month”,...)).
[0005]
In the display of a table such as a form as shown in FIG. 32, it is often impossible to display the entire table on one screen due to restrictions on the display screen size. Therefore, an operation for displaying a desired row or column in the scroll area 220 is required.
[0006]
As an operation as described above, conventionally, a method of “suppressing” and “suppressing suppression (resuming display)” the display output of an arbitrary column of a table is known. Such “display suppression” and “display resumption” are conventionally designated by the following operations.
[0007]
{Circle around (1)} First, select the column you want to suppress (hide) from the table, and then specify the “Hide” item from the menu. Also, when canceling display suppression and “resuming display” for a hidden column, first specify both sides (columns at both ends) that are suppressed (hidden), then Specify the "Redisplay" item in the menu.
[0008]
(2) Using the “column display” dialog box effective for the entire table, batch display / non-display of each column is designated. In this case, a check box for displaying or hiding is checked for each column in the dialog box.
[0009]
[Problems to be solved by the invention]
However, the methods (1) and (2) have the following problems. First, in the case of the method {circle around (1)}, there is a problem that an operation of releasing suppression of a column whose display is suppressed is not intuitive for the user and is difficult to understand. In addition, in order to change the display state of the table outside the display range of the current screen, it is necessary to perform an operation such as scrolling so that the corresponding column is displayed in advance. was there.
[0010]
In the method (2), since another window such as a dialog box is used, there is a problem that the number of operation procedures for designation increases and the operation is troublesome. In addition, when display / non-display is specified for a plurality of columns, there is a problem that it is not possible to confirm whether the table can be displayed as specified until the “OK” button in the dialog box is operated.
[0011]
In the conventional table display, scrolling is sequentially performed in units of one column. For this reason, for example, when a column that is not displayed on the screen is to be displayed by scrolling, it takes time to display the column, and how much scrolling should be performed is not actually scrolled. It was inconvenient to know.
[0012]
The object of the present invention is to enable real-time confirmation while quickly specifying whether to display / hide table columns, and to easily specify display / non-display for columns that are not displayed on the current screen. Is to be able to do it. Furthermore, it is to realize scrolling so that a desired column can be immediately displayed at a predetermined position.
[0014]

[0020]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a system configuration of an information processing apparatus including a table display control apparatus according to an embodiment of the present invention.
[0021]
In the figure, the table information table 10 includes a table data storage unit 11, a table row number storage unit 13, and a table column number storage unit 15.
The table data storage unit 11 is a memory for storing data of a binding table having a hierarchical structure (hereinafter sometimes simply referred to as a table). The table row number storage unit 13 is a memory for storing the total number of rows in the table. The table column number storage unit 15 is a memory for storing the total number of columns in the above table.
[0022]
Based on the information stored in the table information table 10, the table data generation unit 20 generates table data (column header data, item row data, etc.) necessary for displaying the above summary table. Write in the display memory 30.
[0023]
The display memory 30 includes a column header buffer 31 and a data row buffer 32. The column header data and the item row data generated by the table data generator 20 are written in the column header buffer 31 and the data row buffer 32, respectively.
[0024]
The display attribute table 40 is a memory that stores attribute information of each column of the above-described binding table. The attribute information includes “column name”, “column width”, “column display flag W”, “column display flag S”, “display state flag”, and “selected state flag”.
[0025]
The column name is the name of each column in the above table. The column width is the width of each column in the above table. The column display flag W is a flag indicating display / non-display designation of each column of the above-mentioned table selected on the column name list control described later. The column whose column display flag W is “display designation” is displayed, and the column “non-display designation” is not displayed (display suppression). The column display flag S is a flag indicating the display / non-display state of each column of the above-mentioned table that is displayed or hidden after a jump scroll operation described later. A column whose column display flag S is “display” is displayed, and a column “non-display” is not displayed.
[0026]
The display status flag is a flag indicating whether each column of the above-mentioned table is currently within the display screen (within the display range) or outside the display screen (out of the display range). Here, the columns within the display range indicate the leftmost column and the rightmost column that are completely displayed on the screen of the display device 90, and the columns existing between these columns.
[0027]
The selection state flag is a flag indicating whether each column of the above-mentioned table is currently selected or not selected. As will be described later, in the present embodiment, a plurality of columns to be displayed or hidden can be selected by dragging the mouse on the column name list control, and then any one of the plurality of columns is double-clicked ( By clicking (W), the plurality of columns can be displayed or hidden. The selection state flag is a flag for storing whether each column is selected (selected) or not selected during the selection operation.
[0028]
Each column constituting the bundling table is always divided into a fixed column (fixed item column) to be displayed and a scrollable column (scroll column to display data). The scroll column is divided into a display column displayed on the screen and a non-display column not displayed on the screen. The display / non-display of the scroll column is controlled by a column display flag W and a column display flag S as described later. In the table, an area composed of fixed columns is called a fixed display area (or fixed item display area), and an area composed of scroll columns is called a scroll area.
[0029]
The column width information table 50 is a table for storing “start point X coordinate” and “column width (X coordinate width)” on the screen for each column of the above-described table. The X axis is an axis parallel to the horizontal direction of the screen.
[0030]
The column name list data buffer 60 is a buffer for storing list data of column names displayed in a list on the column name list control displayed on the screen.
The display control unit 70 refers to the column name list data buffer 60 and causes the column name list control to be displayed below the screen of the display device 80. Further, the table data display control unit 70 accesses the display memory 30 to read out the column header data of the above-mentioned binding table from the column header buffer 31 and corresponding display data of the item row data of the above-mentioned binding table from the data row buffer 32. And a summary table is displayed on the screen of the display device 80 based on these data.
[0031]
The display control unit 70 includes a register 71 in which the column number of the last column of the scroll table in the above table (the last column number in the table) is set, and a register 72 in which the “effective scroll width” in the above table is set. , A register 73 in which the column number of the leftmost column to be scrolled (scroll start column number) in the above table is set, and the column number of the column displayed at the left end of the scroll region (current scroll region left end column number) is set The register 74 is provided.
[0032]
As will be described later, the display control unit 70 performs display control of the binding table based on the basic information set in the registers 71 to 74.
In the present embodiment, as shown in FIG. 1, for the “table last column number”, “effective scroll width”, “scroll start column number”, and “scroll start column number”, “ Variable names of “Cmax”, “Wscr1”, “Cscr1”, and “GridCscr1” are assigned.
[0033]
The display control unit 70 has a logic view area, which will be described later, as a display work memory, although not particularly shown in FIG. The contents of the display data drawn in the logical view area are displayed on the display device 90.
[0034]
The display device 80 is a display such as a CRT display, LCD, FED (Field Emission Display), or plasma display.
[0035]
The input device 90 performs input for generating a summary table, data input to the summary table, display / non-display setting of each column of the scroll region of the summary table, jump scroll operation of the scroll region, and the like. For example, the input device includes a pointing device such as a keyboard and a mouse.
[0036]
The mouse operation event processing unit 100 notifies the display control unit 70 of occurrence of events of various operations (single click, double click, mouse button down, drag, mouse button up, etc.) on the input device 90 by a message. Although not particularly shown, an event processing unit for notifying the display control unit 70 of a keyboard operation event in the input device 90 is also provided.
[0037]
The external storage device 110 is a storage device that stores the data of the binding table developed in the table information table 10, and includes a hard disk device, an optical disk device, and the like.
FIG. 2 is a diagram showing a data structure of the display attribute table 40. As shown in FIG.
As shown in the figure, the display attribute table 40 includes “column name”, “column width” for each column represented by column numbers “C1”, “C2”, “C3”,. , “Column display flag W”, “column display flag S”, “table display state flag”, and “selection state flag” are stored. That is, for example, for the column with column number “C1”, the column name “XXX”, the column width “W1”, the column display state flag W “1”, the column display state flag S “1”, and the display state flag “1” And a selection state flag “0” are stored. In this embodiment, the column number is a sequential number starting from “0”. That is, C1 = 0, C2 = 1,... Cn = n-1.
[0038]
In the present embodiment, “column name”, “column width”, “column display flag W”, “column display flag S”, “table display state flag”, and “selection state flag” are respectively “Name”. ”,“ Width ”,“ ShowFlgW ”,“ ShowFlgS ”,“ DispAreaflg ”, and“ SelectAreaflg ”. These variables become members of a structure named ColmStTbl [C] (C is a column number).
[0039]
ShowFlgW indicates “display designation” when “1” (True), and “non-display designation (display suppression designation)” when “0” (False). ShowFlgS indicates “displaying” when “1” (True), and “not displaying” when “0” (False). As will be described later, ShowFlgW and ShowFlgS are flags related to double-click and single-click operations, respectively.
[0040]
DisAreaflg indicates “inside display range” when “1” (True), and “outside display range” when “0” (False). In addition, Select Areaflg indicates “selected” when “1” (True), and “unselected” when “0” (False).
[0041]
FIG. 3 is a diagram showing a data structure of the column width information table 50. As shown in FIG.
As shown in the figure, the column width information table 50 is displayed on the screen of the display device 90 for each column represented by a column number of “Ci” (i = 1, 2, 3,... N). The starting point X coordinate “Xi” and the display row width “Wi” are stored.
[0042]
FIG. 4 shows the data structure of the column name list data buffer 60. As shown in FIG.
As shown in the figure, the column name displayed on the display device 90 for each column represented by the column number of the column width information table 50, “Ci” (i = 1, 2, 3,... N). Stores the column names (column heading names) listed in the list control. As is clear from FIG. 3 and FIG. 4, the display width of the “column heading name” is equal to the “column width”.
[0043]
FIG. 5 is a conceptual diagram illustrating a table drawing method by the display control unit 70.
A physical view area 210 shown in the upper part of FIG. 5 is a memory that stores all display data of the table, and corresponds to the display memory 30. Accordingly, display data for all columns and all rows of the table is drawn in the physical view area 210. This drawing is performed by the table data generation unit 20. The physical view area 210 includes a fixed item drawing area 211 and a scroll item drawing area 213. Display data of all fixed items (fixed columns) is drawn in the fixed item drawing area 211, and display data of all scroll items (scroll columns) is drawn in the scroll item drawing area 213.
[0044]
On the other hand, the logical view area 220 is a memory for storing display data of a table that is actually displayed on the display device 90, and is composed of a fixed item drawing area 221 and a scroll item drawing area 223 like the physical view area 210. The In the fixed item drawing area 221 and the scroll item drawing area 223, the display data of the fixed area of the table displayed on the display device 90 and the display data of the scroll area are stored, respectively. The display control unit 70 reads display data of a table to be displayed from the physical view area 210 and draws it in the logical view area 220. The display device 90 reads the display data drawn in the logical view area 220 and displays a table on the screen based on the display data.
[0045]
The column drawn in the fixed item drawing area 221 of the logical view area 220 is fixed (because it is a fixed column), but the scroll column drawn in the scroll item drawing area 223 is variable. As will be described later, the scroll column drawn in the scroll item drawing area 223 in response to a jump scroll operation on the column name list control or a display / non-display designation operation for a single or a plurality of scroll columns. Because it changes.
[0046]
The total width of the scroll columns drawn in the scroll item drawing area 223 of the logical view area 220 is Wscr1. Therefore, the sum of the column widths of the scroll columns in the scroll item drawing area 213 of the physical view area 210 drawn in the logical view area 220 is also Wscrl. Further, the column number of the column of the scroll item drawing area 223 of the physical view area 210 drawn at the left end of the scroll item drawing area 223 of the logical view area 220 is set to GridCscr1. FIG. 5 shows a drawing from the physical view area 210 to the logical view area 220 when all the scroll columns within the range of at least Wscr1 in the column direction from the left end of the column whose column number is GridCsrl are designated for display. Yes.
[0047]
In this embodiment, the total number of rows in the table is (Lmax + 1), and an integer serial number starting with “0” from the first row is assigned to each row in the table. The pitch of each row (equal to the cell width) is Lpitch.
[0048]
The scroll column drawn in the scroll item drawing area 223 of the logical view area 220 is determined by a column display state flag (ShowFlgW) in the display attribute table 40, as will be described later. Therefore, the display data of the fixed column drawn in the fixed item drawing area 211 is always drawn in the logical view area 220, but the display data of the scroll column drawn in the scroll item drawing area 213 is scrolled. In addition to the operation, whether or not drawing is performed is determined by the value of ShowFlgW in the column. Therefore, as shown in FIG. 5, display data of continuous scroll columns in the scroll item drawing area 213 is not necessarily drawn in the scroll item drawing area 223 of the logical view area 220.
[0049]
Further, since it is impossible to display all the rows of the table on the screen of the display device 90, the display rows in the physical view area 210 change according to the vertical scroll. In FIG. 5, the display area of the fixed item drawing area 211 and the scroll item drawing area 213 (area drawn in the logical view area 220) is hatched with a shaded rectangle (display area 211D) and a right diagonal line, respectively. A rectangle (display area 213D) is shown.
[0050]
Since the line included in the display area 211D in the fixed item drawing area 211 and the line included in the display area 213D in the scroll item drawing area 213 are changed by the horizontal scroll operation, the contents of the logical view area 220 are also changed accordingly. Will change. Further, in the present embodiment, a column to be hidden (a column to be suppressed) is designated by an operation on a column name list control, which will be described later, so that the display area 213D in the scroll item drawing area 213 is displayed. The configuration changes. For this reason, the display area 213D of the scroll item drawing area 213 is not necessarily a single rectangle, and may be composed of a plurality of discrete rectangles (a plurality of discrete scroll rows).
[0051]
Next, the overall operation of the information processing apparatus of FIG. 1 will be described with reference to the flowchart of FIG.
First, data related to the binding table is read from the external storage device 110 to generate the table information table 10 (step S1).
[0052]
As a result, the table data is stored in the table data storage unit 11, the total number of rows in the table is stored in the table row number storage unit 13, and the total number of columns in the table is stored in the table column number storage unit 15.
Next, the table data generation unit 20 generates table data with reference to the table information table 10 described above. The table column header data and the table data header data are respectively converted into a column header buffer 31 and a data row column. Store in the buffer 32 (step S2).
[0053]
Subsequently, the display control unit 70 refers to the display attribute table 40 and the column width information table 50 to read out table data (column heading part data and data part data) to be displayed from the display memory 30, and displays the display data. Is written on the display device 90 (step S3).
[0054]
As a result, the initial screen of the table is displayed on the display device 90.
Next, the display control unit 70 refers to the display attribute table 40 and the column name list data buffer 60 to generate column name list data in the column name list data buffer 60 (step S4), and the column name list data. Is written on the display device 90 (step S5).
[0055]
Thereby, column name list data (column name list control) is displayed on the screen of the display device 90.
Through the above processing, the initial screen 300 as shown in FIG. 28 is displayed on the display device 90. In the initial screen 300, a column name list control 301 is displayed at the lower left of the screen. The column name list control 301 displays a list of column names of the table (product sales record table) displayed on the display device 90, and the column names and non-display columns (not completely displayed) of the display columns. Column names of columns and columns that are not displayed at all are displayed in different display forms.
[0056]
In the present embodiment, the display column names (“product code” to “stock quantity”) are displayed in black with white as a background. In addition, non-displayed column names (“number of inventory months” to “01 month”) are displayed in black with gray as a background. Further, the column name frame of the display column is displayed with a solid line, and the column name frame of the non-display column is displayed with a broken line (dotted line).
[0057]
Next, the mouse operation event processing unit 100 determines whether or not a mouse operation event for the column name list control has occurred (step S6). If it has not occurred (NO in step S6), the process of step S6 is repeated. .
[0058]
As shown in FIG. 7, in this embodiment, the types of mouse operations include “mouse button down” (see FIG. 7B), “mouse drag and master button up” (see FIG. 7C). And “double click (W click)” (see FIG. 4D).
[0059]
In the present embodiment, by these mouse operations, it is possible to select a plurality of columns from “display” to “non-display” (display suppression) or from “non-display” to “display”. . Here, a method of the selection operation in the column name list control will be described with reference to FIG.
[0060]
FIG. 18A shows an initial display of the column name list control 301 (see FIG. 28). In this state, in order to “hide” the columns from the “rough rate” column to the “month of inventory”, first, as shown in FIG. 7B, the “rough rate” of the column name list control 301 is displayed. The mouse cursor 303 is overlaid on the display portion of "" and the mouse button is lowered.
[0061]
Next, as shown in FIG. 6C, after the mouse cursor 303 is moved to the “inventory months” display portion while the mouse button is pressed (mouse button is down) (after drag operation). Release the mouse button (up the mouse button). By the mouse operation so far, the column from the “rough rate” column to the “inventory month” column is selected (in this embodiment, the background color of those column names is blue).
[0062]
Subsequently, as shown in FIG. 4D, the mouse cursor is overlaid on the “stock quantity” display portion in the selection range in which the background color is blue, and double-clicked.
By the above mouse operation, the columns of “rough rate”, “stock quantity”, and “month of inventory” are designated as “non-display”, and their ShowFlgW is changed from “display designation” (True) to “non-display designation”. It changes to (False).
[0063]
As a result, the columns of “Roughness” and “Number of inventory” disappear from the screen, and the column after “Current month” is displayed after “Number of purchases” (the column of “Number of inventory” is not displayed). As the display of the table changes, the display of the column name list control 301 also changes. That is, the column names of “rough rate”, “inventory quantity”, and “inventory month number” designated to be hidden are displayed in bold white with a gray background. Also, the “rough rate” and “inventory quantity” frames also change from a solid line to a broken line (the “inventory month” frame remains a broken line).
[0064]
In this way, as a result of the “Gross rate”, “Inventory quantity”, and “Inventory month” columns being hidden, the columns after “Current month” are displayed following the “Gross profit” column. In addition, the display is moved to the left on the screen, and the columns up to “current month” and “March” are completely displayed. As a result, in the display of the column name list control 301, the column names “current month” and “March” are displayed in black with white as a background. In addition, the frame of these column names also changes from a broken line to a solid line.
[0065]
As described above, in the present embodiment, it is possible to change the setting of the ShowFlgW of a column that is not currently displayed by a mouse operation on the column name list control 301. Further, not only a plurality of columns but also a single column display / non-display can be designated. FIG. 8 is a diagram illustrating an example of such single column non-display designation.
[0066]
The figure shows a display state when only the column “March” is changed from “display designation” to “non-display designation”. In this case, the mouse cursor may be overlaid on the column name display portion of “March” of the column name list control 301 and the display may be double-clicked. As a result, in a subsequent operation, when the horizontal scroll is performed in the left direction, the column of “March” is not displayed, and the column of “02 month” is displayed after the column of “current month”. In this way, display / non-display designation of a single column can be performed by a one-touch operation by simply double-clicking a column name on the column name list control 301.
[0067]
Returning to the description of the flowchart of FIG.
If it is determined in step S6 that a mouse operation event has occurred (step S6, NO), it is determined whether the event is a jump scroll operation event (step S7).
[0068]
In the present embodiment, an operation of single-clicking on “column name” on which the mouse cursor on the column name list control 301 overlaps corresponds to the jump scroll operation. When this jump scroll operation is performed, the entire table is horizontally scrolled so that the column with the column name that has been single-clicked becomes the first scroll item of the table (the column displayed at the leftmost end).
[0069]
If it is determined in step S7 that the jump scroll operation has been performed (step S7, YES), jump scroll processing is executed (step S8), and then the process returns to step S6.
[0070]
On the other hand, if it is determined in step S7 that the operation is not a jump scroll operation (step S7, NO), it is determined whether or not the operation is to designate “display / non-display of column” in FIG. 7 described above (step S9). If it is a column display / non-display designation operation (step S9, YES), a column display / non-display process is executed (step S10), and then the process returns to step S6.
[0071]
If it is determined in step S9 that the operation is not a column display / non-display designation operation (step S9, NO), nothing is done and the process returns to step S6.
In this way, the message loop process in steps S6 to S10 is executed while the system is activated.
[0072]
FIG. 9 is a flowchart for explaining the jump scroll process in step S8.
When a single click (S click) is performed on the column name list control 301, the mouse operation event processing unit 100 displays the information indicating that the generated event is a single click operation and the column number of the column of the single clicked column name. Is notified to the display control unit 70.
[0073]
When the display control unit 70 receives this message, the display control unit 70 executes the processing of the flowchart of FIG.
That is, the display control unit 70 first sets the column number set in the message to the variables Csno and GridCscr1 (step S11). Next, the value of Cscrl is set in the variable C (step S12). As a result, the column number of the scroll column that has been S-clicked is set in Csno. In addition, the column number of the scroll column to be displayed at the left end of the scroll area of the table is set in GridCscr1, and the column number of the scroll start column is set in C.
[0074]
Next, it is determined whether C <Csno (step S13). If C <Csno is “True”, then ColmStTbl [C]. ShowFlgS is set to “False” (step S14). On the other hand, if “False”, ColmStTbl [C]. ShowFlgS is set to “True” (step S15).
[0075]
After the process of step S14 or S15, the value of the variable C is incremented by “1” (step S17), and it is determined whether C> Cmax is satisfied (step S17).
If C> Cmax is “False”, the process returns to step S13.
[0076]
In this way, ColmStTbl [Ci]. Of column Ci whose column number is smaller than Csno. ShowFlgS is set to “False” and ColmStTbl [Cj] .C of column Cj whose column number is Csno or higher. ShowFlgS is set to “True”.
[0077]
Then, as described above, ColmStTbl [C]. When the setting of ShowFlgS is completed, an S click column display switching method, which will be described later, is called for the display target table object with the variable Csno as an argument (step S18).
[0078]
By executing this S-click column display switching method, the display data of the scroll item drawing area 113 in the physical view area 210 is redrawn in the logical view area 220. Then, as shown in FIG. 5, a table that is jump-scrolled on the screen of the display device 90 so that the column whose column name is S-clicked on the column name list control 301 is displayed at the head of the scroll area. Is displayed.
[0079]
Subsequent to step S18, a column display area determination routine, which will be described later, is called and ColmStTbl [C]. The value of DisplayAreaFlg is set (step S19), and then a column name list control display routine is called (step S20). By calling this column name list control display routine, the column name list control 301 is displayed in a format corresponding to the table display format displayed in step S22. Details of the column name list control display routine will also be described later.
[0080]
FIG. 10 is a diagram showing an overall flow of the column display / non-display processing in step S10.
In this flow, first, a mouse button down process is performed (step S31). In this mouse button down process, as shown in FIG. 7B, the column name list control 301 changes the background color of the column name for which the mouse button down operation has been performed. Details of this mouse button down processing routine will be described later.
[0081]
Next, mouse button down & mouse move processing is performed (step S32). In this mouse button down & mouse move process, as shown in FIG. 7C, the column name list control 301 changes the background color of the column name selected in accordance with the mouse drag operation. Details of this mouse button down & mouse move processing routine will also be described later.
[0082]
Subsequently, mouse button up processing is performed (step S33). In this mouse button up process, as shown in FIG. 7C, the column name list control 301 changes the display form of the column names within the selection range designated by the mouse button down operation and the mouse button up operation. And ColmStTbl [C]. Set Flag to “True” (when multiple columns are selected) or “False” (when a single column is selected). Details of the mouse button up processing routine will also be described later.
[0083]
Finally, a mouse double click (mouse W click) process is performed (step S34). In this mouse W click process, as shown in FIG. 7D, the ShowFlgW of the column determined by double clicking on the column name list control 301 is changed. In response to this change, the display form of the column name list control 301 and the display contents of the scroll area of the table are changed. Details of the mouse button W click processing will also be described later.
[0084]
FIG. 11A is a flowchart showing details of the initialization process of the entire display attribute table 40 (ColmStTbl [C]) performed by the display control unit 70. The process of the flowchart of FIG. 11A is performed in step S4 of the flowchart of FIG.
[0085]
First, the table object to be displayed is read from the table data storage unit 11 of the table information table 10, the effective scroll width is set to Wscrl, the scroll start column number to Cscrl (the column number of the leftmost column to be scrolled) , Cmax is set to the last column number of the table object, and GridCscr1 is set to the leftmost column number of the current scroll area (in this stage, GridCscr1 = Cscr1) (step S41).
[0086]
Next, the variable C is initialized to “0” (step S42), and then it is determined whether Cscr1 is “0” (step S43). A table object in which Cscrl is “0” is a table object having no fixed column.
[0087]
Subsequently, if Cscr = 0 is “False”, the display attribute of each fixed column is set from the table object to the display attribute table ColmStTbl [i] (i is a column number) of each fixed column (step S44).
[0088]
In the present embodiment, it is assumed that the display attribute table 40 includes a display attribute table ColmStTbl [i] for each column. This display attribute table ColmStTbl [i] is defined as a structure as schematically shown in FIG. This structure has Name, Width, ShowFlgW, ShowFlgS, DispAreaFlg, and SelectAreaFlg as members. A column name, a column width, a column display flag W, a column display flag S, a display state flag, and a selection state flag are set in the members Name, Width, ShowFlgW, ShowFlgS, DispAreaFlg, and SelectAreaFg, respectively (see FIG. 2). ).
[0089]
Therefore, in step S44, ColmStTbl [C]. Name, ColmStTbl [C]. Width, ColmStTbl [C]. ShowFlgW, ColmStTbl [C]. ShowFlgS, ColmStTbl [C]. DispAreaFlg, ColmStTbl [C]. In SelectAreaFlg, column name C, column width, column display flag W value (= True), column display flag S value (= True), display state flag value (= True), and selection state flag value (= False) is set.
[0090]
Next, the value of C is incremented by “1” (step S45), and then it is determined whether C ≧ Cscrl (step S46). If C ≧ Cscr1 is “False” (false), the process returns to step S43.
[0091]
In this manner, the processing of steps S43 to S46 is repeated until C ≧ Cscr1 becomes “True”, and the attribute information of the fixed column of the display attribute table 40 is set.
[0092]
If it is determined in step S46 that C ≧ Cscr1 is “True”, that is, C = Cscr1, the display attribute of the scroll column is set from the table object to the display attribute table ColmStTbl [C] of the scroll column ( Step S47).
[0093]
The process of step S47 is the same as the process of step S43 described above except that the value of the variable C indicates the column number of the scroll column.
Subsequent to step S47, the value of the variable C is incremented by “1” (step S48), and then it is determined whether C> Cmax is satisfied (step S49). Then, while C> Cmax is “False”, the processing of steps S47 to S49 is repeated to set the attribute information of all the scroll columns (column numbers of Cscrl to Cmax) in the display attribute table 40.
[0094]
When it is determined that C> Cmax is “True” (step S49, YES), the column display area determination routine is called, the value of DisplayAreaFlg in the display attribute table 40 is set (step S50), and the process returns to the caller. . Details of the display area determination routine for the row will be described later.
[0095]
Next, details of the “S click column display switching method” in step S22 of the flowchart of FIG. 9 will be described with reference to the flowcharts of FIGS.
[0096]
First, the variable C (column number counter) and the variable Cpno are both set to “0” (step S51).
Next, the values of the variable C and Cscr1 are compared (step S52). If C <Cscrl, ColmStTbl [C]. ShowFlgW is determined (step S53), and ColmStTbl [C]. If ShowFlgW is “True”, the value of Cpno is set to ColmStTbl [C]. It increases by the value of Width (step S54). Then, the value of C is incremented by “1” (step S55), and the process returns to step S52.
[0097]
In this way, the coordinate of the right end of the scroll item drawing area 223 of the logical view area 220 is set to the variable Cpno.
If it is determined in step S52 that C ≧ Cscr1 (in this case, C = Cscr1), both the variable L serving as the line number counter and the variable Lp in which the drawing line coordinates are set are set to “0”. Initial setting is performed (step S56). Next, the value of the argument Csno is set in the variable C, and the value of Cpno is set in the variable Cp (step S57).
[0098]
As a result, the left coordinate of the drawing position on the scroll item drawing area 223 of the logical view area 220 of the cell to be drawn in the variable Cp, that is, the scroll item drawing area of the logical view area 220 of the cell of the single clicked column. The left coordinate of the drawing position in 223 is set.
[0099]
Subsequently, ColmStTbl [C]. ShowFlgW is determined (step S58), and ColmStTbl [C]. If ShowFlgW is “True”, the “1-cell drawing” routine is called to draw the display data of DataTbl [C, L] in the scroll item drawing area 223 of the logical view area 220 (step S59).
[0100]
Here, the table is composed of a plurality of cells. The display data of each cell is stored in the display memory 30 (physical view area 210) DataTbl [i, j] (i is a row number, j is a column number). ) Is stored as array data.
[0101]
FIG. 14 is a diagram schematically showing a method of drawing the display data DataTbl [C, L] of the cell having the column number C and the row number L in the logical view area 220 in step S59.
[0102]
As shown in the figure, the drawing area on the logical view area 220 of each array data DataTbl [C, L] of the table data table is the cell left coordinate (drawing column coordinate indicating the column coordinate of the left frame of the cell) Cp. And cell upper coordinates (drawing line coordinates indicating the line coordinates of the upper frame of the cell) Lp, cell width ColmStTbl [C]. It is determined by the width and the cell height Lpitch.
[0103]
The 1-cell drawing routine uses Cp, Lp, ColmStTbl [C]. Width, Lpitch, and DataTbl [C, L] are received, and DataTbl [C, L] is drawn in the relevant area of the logical view area 220 as shown in FIG.
[0104]
Subsequent to step S59, the value of Cp is changed to ColmStTbl [C]. It increases by the value of Width (step S60). Then, the value of C is incremented by “1” (step S61), then the values of C and Cmax are compared (step S62), and if C ≦ Cmax, the process returns to step S58.
[0105]
If “False” is determined in step S58, the drawing of DataTbl [C, L] is not performed, and the process proceeds to step S61.
If it is determined in step S62 that C> Cmax, the value of Lp is increased by Lpitch (step S63), and then the value of L (row number) is incremented by “1” (step S64). Then, L and Lmax (final line number) are compared (step S65), and if L ≦ Lmax, the process returns to step S57. On the other hand, if it is determined in step S65 that L> Lmax, the process returns to the caller.
[0106]
In this way, the drawing in the scroll item drawing area 223 of the logical view area 220 of the column after the single-clicked column (column number Cno) is performed in units of one line by the loop processing of steps S58 to S62. . This drawing is performed in the order of the row numbers from the 0th row (row whose row number is “0”).
[0107]
In addition, by the loop processing of steps S57 to S65, the drawing in the scroll item drawing area 223 of the logical view area 220 of the column after the single-clicked column (column number Cno) is performed on all the rows. As a result, when a jump scroll operation is performed by single click, the single clicked column is displayed at the left end of the scroll region, and the single clicked column follows from the left end within the effective scroll width Wscr1. Columns (provided that ColmCtrl.ShowFlgW is set to “True”) are continuously displayed. This is because, in step S58, the scroll item drawing area 223 of the logical view area 220 has ColmStTbl [C]. This is because only the cells in the column whose ShowFlgW is “True” are drawn.
[0108]
The basic information (Cmax, Lmax, Lpitch) used by the column display switching method is stored in the table information table 10 in advance, and the display control unit 70 stores these basic information from the table information table 10. Read and execute the S-click column display switching method.
[0109]
In this way, the display data of the columns designated for display after the single-clicked column is rendered in the scroll item rendering area 223 of the logical view area 220 shown in FIG. 5 by the S-click column display switching method. The Then, for example, a screen 400 as shown in FIG. 29 is displayed on the display device 90.
[0110]
The screen 400 is a screen that is displayed when “inventory months” is single-clicked on the column name list control 301 in the initial display screen 300 shown in FIG. 28. By this single click operation, as shown on the screen 400, scroll display control is performed such that the column “number of months in stock” is displayed at the left end of the scroll area of the table. As described above, in this embodiment, the column name of the scroll column is controlled by single-clicking on the column name list control 301 so that the scroll column is displayed at the left end of the scroll area of the table.
[0111]
Therefore, the user can simply display a column that has not been displayed on the screen up to now, or can display a desired column or column of the table by a simple operation of single-clicking the column name on the column name list control 301. The group can be displayed at a position where it can be easily seen.
[0112]
In the present embodiment, the display form related to the column name of the scroll column on the column name list control 301 is also changed in accordance with the change in the screen display of the table. For example, when the screen changes from the initial screen 300 to the screen 400, the upper and lower frame lines of the column names from “sales” to “stock quantity” change from “solid line” to “dashed line” in the column name list control 301. On the contrary, the upper and lower frame lines of the column names from “number of months of inventory” to “January” change from “broken line” to “solid line”. As a result, the user can easily recognize whether or not there is a left column from the leftmost column displayed on the screen by displaying the column name list control 301. These display controls are executed by the processing described below.
[0113]
FIG. 15 is a flowchart illustrating details of the “column display area determination” routine in step S19 of FIG.
First, Wscr1, Cscr1, Cmax, and GridCsrl, which are basic information of the table, are read from the registers 71 to 74 (step S71).
[0114]
Next, the value of Cscr1 is substituted for variable C, and variable Csum is initialized to “0” (step S72). As a result, the column number of the scroll start column is set in the variable C. The variable Csum is a variable for calculating the total column width of the scroll area.
[0115]
Subsequently, ColmStTbl [C]. ShowFlgS is determined (step S73). Then, ColmStTbl [C]. If ShowFlgS is "False", the process proceeds to step S78. If ShowFlgS is "True", then ColmStTbl [C]. ShowFlgW is determined (step S74).
[0116]
In step S74, ColmStTbl [C]. If it is determined that ShowFlgW is “True”, Csum and ColmStTbl [C]. The addition result of Width is substituted into Csum (step S75).
[0117]
Next, it is determined whether Csum ≦ Wscr1 (step S76). If Csum ≦ Wscr1 is “True”, then ColmStTbl [C]. DispAreaFlg is set to “True” (step S77), and if Csum ≦ Wscr1 is “False”, then ColmStTbl [C]. “False” is set in DispAreaFlg (step S78).
[0118]
Subsequently, the value of the variable C is incremented by “1” (step S79), and then it is determined whether C> Cmax is satisfied (step S80). If C> Cmax is “False”, the process returns to step S73.
[0119]
As described above, both ShowFlgS and ShowFlgW accumulate the column width Width in order from the start column to be scrolled, for the columns in the scroll region where “True” is set. Then, a scroll row within the display range is determined based on whether or not the accumulated value Csum exceeds the effective scroll width Wscr1. Then, the display state flag DispAreaFlg is set to “True” for the scroll line that is within the display range, and the display state flag DispAreaFlg is set to “False” for the scroll line that is outside the display range.
[0120]
If C> Cmax is “True” in step S89, the processing for setting DispAreaFlg is completed for all the columns in the scroll area, and the process returns to the caller.
[0121]
As a result, only the scroll column in which ShowFlgS and ShowFlgW are both “True” in the scroll column is set to “True”, and DispAreaFlg is set to “True”.
[0122]
FIG. 16 is a flowchart showing details of the column name list control display routine in step S20 of the flowchart of FIG.
In this process, first, the variable C is initialized to “0” (step S91). Next, the leftmost frame line of the column name list control 301 is drawn with a solid line (step S92).
[0123]
Subsequently, the column name list control column unit display routine is called with the argument C, and the column name of the column whose column number is equal to the value of the argument C is drawn on the column name list control 301 (step S93). Subsequently, the value of C is incremented by “1” (step S94), and it is determined whether C> Cmax is satisfied (step S95). If C> Cmax is “False”, the process returns to step S93.
[0124]
As described above, the column name list control 301 is drawn. If it is determined in step S95 that C> Cmax is “True”, that is, the drawing of the column name list control 301 is completed up to the final column name, ColmStTbl. [Cmax]. DispAreaFlg is determined (step S96), and ColmStTbl [Cmax]. If DispAreaFlg or "True", the rightmost frame line of the column name list control 301 is drawn with a solid line (step S97). On the other hand, if “False”, the rightmost frame line of the column name list control 301 is drawn with a dotted line (broken line) (step S98). Then, after the process of step S97 or S98 is completed, the process returns to the caller.
[0125]
FIG. 17 is a detailed flowchart of the column name list control unit display routine in step S93.
In the flowchart of FIG. 9, steps S101 to S109 are processes related to columns within the display range, and steps S110 to S117 are processes related to columns outside the display range.
[0126]
First, ColmStTbl [C]. DispAreaFlg is determined (step S101), and ColmStTbl [C]. If DispAreaFlg is “True”, the upper and lower frame lines of the column name of column number C are drawn as solid lines (step S102). Next, ColmStTbl [C]. ShowFlgW is determined (step S103), and ColmStTbl [C]. If ShowFlgW is “True”, then ColmStTbl [C]. SelectAreaFlg is determined (step S104).
[0127]
Then, ColmStTbl [C]. If SelectAreaFlg is “True”, the column name of column number C is drawn in black with the background color blue (step S105). On the other hand, if it is “False”, the column name of column number C is drawn in black with the background color white (step S106).
[0128]
If “False” in step S103, ColmStTbl [C]. SelectAreaFlg is determined (step S107), and ColmStTbl [C]. If SelectAreaFlg is “True”, the column name of column number C is drawn in white bold with the background color blue (step S108). On the other hand, if it is “False”, the column name of column number C is drawn in white bold with the background color as gray (step S109).
[0129]
As a result of the above processing, all the column names of the columns within the display range and designated for display are displayed in black, but depending on whether or not they are currently selected, the background Is displayed in blue (selected) and white (non-selected) colors. In addition, the column names of columns that are in the display range and that are not specified for display are all displayed in white bold, but depending on whether or not they are currently selected, the background Is displayed in blue (selected) and white (non-selected).
[0130]
In this way, in the display of the column name list control 301, whether the column name of the column within the display range is currently display designation or non-display designation, and is selected or not selected 4 Depending on the state of the type, it is displayed in four types. After the process of step S105, S106, S108, or S109 is completed, the process returns to the caller.
[0131]
If “False” in step S101, the upper and lower frame lines of the column name of column number C are drawn with dotted lines (step S110). Next, ColmStTbl [C]. It is determined whether ShowFlgW is “False” (step S111), and ColmStTbl [C]. If ShowFlgW is “True”, then ColmStTbl [C]. SelectAreaFlg is determined (step S112).
[0132]
Then, ColmStTbl [C]. If SelectAreaFlg is “True”, the column name of column number C is drawn in black with the background color blue (step S113). On the other hand, if it is “False”, the column name of the column number C is drawn in black with a gray background color (step S114).
[0133]
In step S111, ColmStTbl [C]. If ShowFlgW “False”, then ColmStTbl [C]. SelectAreaFlg is determined (step S115). Then, ColmStTbl [C]. If SelectAreaFlg is “True”, the column name of column number C is drawn in white bold with the background color blue (step S116). On the other hand, if it is “False”, the column name of column number C is drawn in white bold with the background color as gray (step S117).
[0134]
Then, after the process of step S113, S114, S116, or S117, the process returns to the caller.
In this way, scroll names outside the display range are also displayed in four types of column names according to the true / false values of ShowFlgW and SelectAreaFlg. All the column names of columns that are outside the display range, that is, not currently displayed, are displayed with dotted upper and lower frame lines. In addition, in the columns outside the display range, all the column names of the columns that are designated for display are displayed in black, but the background is blue (selected) and gray (depending on whether or not it is currently selected) (Not selected) are displayed in a distinguished manner. In addition, in the column outside the display range, the column name of the column that is not specified for display is displayed in bold white, but the background is blue (selected) depending on whether it is currently selected or not. Displayed in gray (not selected). Furthermore, in the present embodiment, for a column that is designated for display and is not in a selected state, whether or not the column is within the display range can be identified by changing the background color. Yes. That is, if the background color of the column name is within the display range, it is displayed in white, and if it is outside the display range, it is displayed in gray.
[0135]
As described above, in the display of the column name list control 301, the column names of the currently selected columns are displayed with a blue background regardless of whether or not they are within the display range. Therefore, the selected column and the unselected column can be identified by the background color of the column name displayed in the column name list control 301. Further, a column designated for display and a column designated for non-display can be identified by the character color of the column name displayed in the column name list control 301. Further, even if a column is designated for display and is not selected, whether or not the column is in the display range depends on the background of the column name displayed in the column name list control 301. Can be identified by color.
[0136]
In addition, the said display form is only an example, It is also possible to identify the state of each column by other display forms.
Next, details of the “mouse button processing” routine in step S31 of the flowchart of FIG. 10 will be described with reference to the flowchart of FIG.
[0137]
The mouse button processing routine receives, as an argument, the column number of the column name where the mouse button is down-operated on the column name list control 301. First, an existing selection cancel routine is called and all ColmStTbl [C]. SelectAreaFlag is set to “False” (step S121). Details of this existing selection cancel routine will be described later.
[0138]
Next, a column name list selection display routine is called to execute processing for changing the display of the column name list control 301 to a form as shown in FIG. 7B, for example. When the column name list selection / display routine is called, the column number received as the argument is passed to the column name list selection / display routine as the first and second arguments (step S122). Details of the column name list selection display routine will also be described later.
[0139]
Subsequently, ColmCtrl. The column number received as the argument is set in Start (step S123), and the process returns to the caller.
FIG. 19 is a flowchart showing details of the existing selection cancel routine in step S121 of FIG.
[0140]
First, ColmCtrl. Flg is determined (step S131). And, ColmCtrl. If Flg is “False”, the process returns to the caller. On the other hand, if “True”, a “display attribute table selection clear” routine is called, and ColmStTbl [C]. SelectAreaFlg is set to “False” (step S132). The details of this “display attribute table selection clear” routine will be described later.
[0141]
Next, ColmCtrl. Flg is set to “False” (step S133), and the process returns to the caller.
Details of the “display attribute table selection clear” routine in step S132 will be described with reference to the flowchart of FIG.
[0142]
First, the variable C is initialized to “0” (step S141). Next, ColmStTbl [C]. SelectAreaFlg is set to “False” (step S142), and then the value of variable C is incremented by 1 (step S143). Then, the values of the variables C and Cmax are compared (step S144). If C> Cmax, the process returns to the caller. If C ≦ Cmax, the process returns to step S142.
[0143]
In this way, ColmStTbl [0]. SelectAreaFlg-ColmStTbl [Cmax]. All SelectAreaFlg are set to “False”. When this setting is completed, it is determined in step S144 that C> Cmax, and the process returns to the caller.
[0144]
Next, details of the “mouse button down & mouse move processing” routine in step S32 of the flowchart of FIG. 10 will be described with reference to the flowchart of FIG.
[0145]
The “mouse button down & mouse move processing” routine is the column number of the column name on the column name list control 301 pointed to by the mouse cursor when the mouse button is currently down from the caller. As an argument. Then, this column number is set as the second argument, ColmCtrl. The column name list selection display routine is called with Start as the first argument, and display control of the column name list control 301 as shown in FIG. 7C is performed (step S151).
[0146]
FIG. 22 is a flowchart showing details of the column name list selection display routine.
First, the “display attribute table selection clear” routine described above is called (step S151). As a result, all columns of ColmStTbl [C]. SelectAreaFlg is set to “False”.
[0147]
Next, Start, which is the first argument, is compared with End, which is the second argument (step S153). As described above, Start is described in ColmCtrl. It is equal to Start (the column number of the column name column on the column name list control 301 that the mouse cursor was pointing to when the mouse button was down), and End is the column name list control 301 currently pointed to by the mouse cursor. Equal to the column number of the above column name.
[0148]
Subsequently, Start and End are compared (step S152). If Start ≦ End, the Start value is set in the variable C0, and the End value is set in the variable C1 (step S153). On the other hand, if Start> End, the value of End is set in the variable C0, and the value of Start is set in the variable C1 (step S154).
[0149]
This process is because the mouse drag operation direction on the column name list control 301 is considered from both left to right and from right to left. Therefore, the process of step S153 is executed if it is from the left to the right, and the process of step S154 is executed if it is from the right to the left. Then, the column number of the leftmost column name and the column number of the rightmost column name when the column name is dragged on the column name list control 301 by the processing of step S153 or S154, respectively, Set to C0 and C1.
[0150]
Next, the value of C0 is set to the variable C (step S155). Subsequently, ColmStTbl [C]. “True” is set in SelectAreaFlg (step S156), and the value of variable C is incremented by “1” (step S157).
[0151]
Then, the values of C and C1 are compared (step S158), and if C ≦ C1, the process returns to step S156. In this way, the loop processing of steps S156 to S158 is repeated until it is determined in step S158 that C> C1. If it is determined in step S158 that C> C1, the above-described column name list control display routine of FIG. 16 is called (step S159).
[0152]
When a column name is dragged on the column name list control 301 by the loop processing of steps S156 to S158 described above, ColmStTbl [C]. Only SelectAreaFlg is set to “True”. Therefore, the background color of the dragged column name changes to blue in the display of the column name list control 301 by the process of step S159. Also, if the mouse button is raised after the drag operation, the column name where the mouse button is down, the column name where the mouse button is raised, and the background color of the column names between those column names Displayed in blue. If the column name with the mouse button down and the column name with the mouse button up are the same even though the drag operation has been performed, the processing of steps S155 to S158 is performed only once. Only the background color of the column name is displayed in blue.
[0153]
Next, details of the mouse button up processing in step S33 of the flowchart of FIG. 10 will be described with reference to the flowchart of FIG.
This mouse button up processing routine receives the column number of the column name pointed to by the mouse cursor when the mouse button is raised on the column name list control 301 as an argument. When a column name is dragged on the column name list control 301, the column number of the column name pointed to by the mouse cursor when the mouse button is dropped (released) becomes the argument.
[0154]
First, the column number and ColCtrl. Start is compared (step S161). And if both are different, ColmCtrl. The column number is set to End, and ColmCtrl. Flg is set to “True” (step S162). On the other hand, if the two match, ColmCtrl. The column number is set to End, and ColmCtrl. “False” is set in Flg (step S163).
[0155]
The process of step S162 corresponds to a process when a plurality of column names are specified by a mouse drag operation on the column name list control 301. On the other hand, the processing in step S163 corresponds to processing when a single column name is designated by a mouse drag operation.
[0156]
When the process of step S162 or S163 is executed, the above-described column name list selection display routine of FIG. 22 is called (step S164), and the process returns to the caller. By the process of step S164, the column name selected on the column name list control 301 is finally determined by the drag operation of the mouse by the user, and these column names are displayed with a blue background color.
[0157]
Next, details of the mouse W click process in step S34 of the flowchart of FIG. 10 will be described with reference to the flowcharts of FIGS.
The mouse W click processing routine receives the column number of the column of the column name W-clicked on the column name list control 301 as an argument. And, first, ColmCtrl. Flg is determined (step S201), and ColmCtrl. If Flg is “False”, the process proceeds to step S211, and if “True”, the process proceeds to step S209.
[0158]
ColmCtrl. Flg being “False” indicates that the number of columns selected as display / non-display designation on the column name list control 301 is one (single selection) (see step S163 in the flowchart of FIG. 23). ). On the other hand, ColmCtrl. Flg being “True” indicates that there are a plurality of columns selected as display / non-display designation on the column name list control 301 (multiple selection is being performed) (see step S162 in the flowchart of FIG. 23). ).
[0159]
In the present embodiment, when a certain column name is directly W-clicked without dragging on the column name list control 301, ColCtrl. Start and ColmCtrl. End is set to the column number of the column name, and ColmCtrl. Assume that Flag is set to “False”, the processing of steps S31 to S33 is skipped, and the mouse W click processing routine of step S34 is executed. Therefore, in this embodiment, a single column can be selected and a display / non-display of the column can be designated by directly W-clicking the single column name on the column name list control 301. Is possible.
[0160]
In the case of single selection, as described above, a single column to be changed from “display” to “non-display” or “non-display” to “display” is clicked on the column name list control 301. . If it is determined in step S201 that it is “False”, the column number of the argument is set in the variable Cno (step S202). Next, ColmStTbl [C]. ShowFlgW is determined (step S203), and ColmStTbl [C]. If ShowFlgW is “True”, then ColmStTbl [C]. ShowFlgW is set to “False” (step S204). On the other hand, if “False”, ColmStTbl [C]. ShowFlgW is set to “True” (step S205).
[0161]
In this way, on the column name list control 301, ColStTbl [C]. Inverts the truth value of ShowFlgW.
Subsequently, the W click column display switching method is called for the table object to be displayed using Cno as an argument (step S206). By calling this W click column display switching method, the scroll item drawing area 223 of the logical view area 220 is updated (the scroll column in which the column name is designated by the W click operation is changed from display designation to non-display designation. Or the display specification changes from the non-display specification, and the column displayed in the scroll area of the table changes accordingly.) Details of this W-click column display switching method will be described later.
[0162]
Next, the above-described column display area determination routine is called (step S207), and similarly, the above-described column name list control display routine is called (step S208), and the process returns to the caller. The display form of the column name list control 301 is changed by the processing in steps S207 and S208. That is, on the column name list control 301, when the designation of a certain column is changed from “display” to “non-display” by W click, the column name of the column changes from black to white. On the other hand, when “non-display” is changed to “display”, the column name of the column changes from white to black.
[0163]
As described above, in this embodiment, by clicking the “column name” of the column on the column name list control 301, the column is displayed from “display” to “hidden”, or from “hidden” to “display”. Can be easily changed.
[0164]
If “True” is determined in step S201 (when it is determined that a plurality of columns are selected on the column name list control 301), the received argument is used as an argument as it is, “column name list control W click processing "Routine is called (step S209), and the process returns to the caller. Details of this column name list control W click processing routine will be described later.
[0165]
Next, the details of the “W click column display switching method” called in step S206 will be described with reference to the flowcharts of FIGS.
First, both the variable C and the variable Cpno serving as the column number counter are initially set to “0” (step S221).
[0166]
Next, the value of the variable C and the argument Cno are compared (step S222). If C <Cno, then ColmStTbl [C]. ShowFlgW or ColmStTbl [C]. It is determined whether ShowFlgS is “False” (step S223), and ColmStTbl [C]. ShowFlgW and ColmStTbl [C]. If ShowFlgS is “True”, the value of Cpno is set to ColmStTbl [C]. It increases by the value of Width (step S224). Then, the value of C is incremented by “1” (step S225), and the process returns to step S222. On the other hand, in step S223, ColmStTbl [C]. ShowFlgW or ColmStTbl [C]. If ShowFlgS is “False”, the process proceeds to step S225.
[0167]
In this way, “display designation” (ColmStTbl [C] .ShowFlgW = True) in “the column from the top column of the table” to “the column immediately before the column clicked by W” is set, and the jump is performed. The total of the column widths of the columns that are not hidden by the scroll operation is set in the variable Cpno. Thereby, in Cpno, the display data of the leftmost column (the column that is W-clicked in the case of single selection) in which the column name is selected on the column name list control 301 is displayed in the logical view area 220 to be drawn. The coordinates of the drawing position in the scroll item drawing area 223 are set.
[0168]
In this embodiment, the jump scroll operation and the W click operation are processed in an integrated manner, and thus such processing is performed. However, the determination in step S223 is only one example, The embodiment may be used. In the present embodiment, when there are display-designated columns among the columns that have disappeared from the screen by the jump scroll operation by the processing after step S226, these columns can be redisplayed by the W click operation. In other words, among the columns disappeared by the jump scroll operation, the display after the column selected by the W click operation (after the selected leftmost column when a plurality of columns are selected by the W click operation described later) is displayed. The designated column (the column in which ColmStTbl [C] .ShowFlgW is “True”) is displayed again.
[0169]
If it is determined in step S222 that C ≧ Cno, both the variable L as a line number counter and the variable Lp in which the drawing line coordinates are set are initially set to “0” (step S226). Next, the value of the argument Cno is set in the variable C, and the value of the variable Cpno (drawing column coordinates) is set in the variable Cp (step S227).
[0170]
Thereby, the drawing column coordinates in the scroll item drawing area 223 of the logical view area 220 of the cell to be drawn (the cell in the selected leftmost column) are set in the variable Cp.
[0171]
Subsequently, ColmStTbl [C]. ShowFlgW is determined (step S228), and ColmStTbl [C]. If ShowFlgW is “True”, the “1-cell drawing” routine is called to draw the display data of the data table DataTbl [C, L] in the scroll item drawing area 223 of the logical view area 220 (step S229). This “one cell drawing” routine is the same as the routine called in step S59 of FIG.
[0172]
Subsequent to step S229, the value of Cp is changed to ColmStTbl [C]. It increases by the value of Width (step S230). Then, the value of C is incremented by “1” (step S231), then the values of C and Cmax are compared (step S232), and if C ≦ Cmax, the process returns to step S228.
[0173]
If “False” is determined in step S228, the drawing of DataTbl [C, L] is not performed, and the process proceeds to step S231.
If it is determined in step S232 that C> Cmax, the value of Lp is increased by Lpitch (step S233), and then the value of L (row number) is incremented by “1” (step S234). Then, L and Lmax (final line number) are compared (step S235), and if L ≦ Lmax, the process returns to step S227.
[0174]
In this manner, the logical view area 220 of the column designated for display after the column (column number Cno) whose column name is W-clicked on the column name list control 301 by the loop processing of steps S228 to S232. Drawing in the scroll item drawing area 223 is performed in units of one line. This drawing is performed in the order of the row numbers from the 0th row (row whose row number is “0”). Thus, only the cells in the column designated as “display designation” are rendered in the scroll item rendering area 223 of the logical view area 220 by the determination in step S228.
[0175]
In addition, by the loop processing of steps S227 to S235, all the drawing in the scroll item drawing area 223 of the logical view area 220 of the column designated for display after the column where the W is clicked (column of column number Cno) is performed. To the line.
[0176]
The basic information (Cmax, Lmax, Lpitch) used by the W-click column display switching method is stored in advance in the table information table 10, and the display control unit 70 receives these basic information from the table information table 10. Read the information and execute the column display switching method for W click.
[0177]
FIG. 27 is a flowchart showing details of the column name list control W click processing routine in step S209 of the flowchart of FIG.
This column name list control W click processing routine performs processing when a plurality of column names are selected on the column name list control 301, and the column in which the column name is clicked on the column name list control 301 as an argument. Receive the column number.
[0178]
This routine starts with ColCtrl. Start and ColmCtrl. The values of End are compared (step S241). As a result, ColmCtrl. Start ≦ ColmCtrl. In the case of End, ColCtrl. The value of Start is changed to ColCtrl. The value of End is set (step S242). On the other hand, ColmCtrl. Start> ColmCtrl. In the case of End, ColCtrl. The value of End is set to ColCtrl. A value of Start is set (step S243).
[0179]
The processes in steps S241 to S243 are processes assuming that the direction of the drag operation on the column name list control 301 is from left to right or from right to left, and the column name is set to C0 by the process in step S242 or S243. The column number of the leftmost column selected by the drag and drop operation on the list control 301 is set in C1, and the column number of the right end selected by the drag and drop operation on the column name list control 301 is set in C1. C0 <C1).
[0180]
Next, it is determined whether or not the condition that the “column number” received as an argument is C0 or more and C1 or less is satisfied (step S244). If the determination result is “True” (satisfying the condition), the process proceeds to step S245. If the determination result is “False” (not satisfying the condition), the process proceeds to step S254. The process of step S244 is a process of determining whether the column name that has been W-clicked on the column name list control 301 is the selected column name. By this process, when a column name other than the column name selected on the column name list control 301 is clicked, the operation is invalidated.
[0181]
In step S245, the value of C0 is substituted for variable C (step S245), and then ColmStTbl [C]. ShowFlgW is determined (step S246). Then, ColmStTbl [C]. If ShowFlgW is “True”, then ColmStTbl [C]. ShowFlgW is set to “False” (step S247). On the other hand, ColmStTbl [C]. If ShowFlgW is “False”, then ColmStTbl [C]. ShowFlgW is set to “True” (step S248).
[0182]
The processing in steps S247 and S248 is performed by using ColmStTbl [C] .C of the column selected on the column name list control 301. This is a process of inverting the true / false value of ShowFlgW. By this inversion processing, the display designation of the selected column is changed from “display” to “non-display” or from “non-display” to “display”.
[0183]
After the process of step S247 or step S248, the value of C is incremented by “1” (step S249), and then the values of C and C1 are compared (step S250). If C ≦ C1, the process returns to step S246.
[0184]
In this way, the loop processing of steps S246 to S250 is repeated, and ColmStTbl [C]. Inverts the truth value of ShowFlgW.
[0185]
When the reversal processing and the like are completed, if it is determined in step S250 that C> C1, then C0 and GridCscr1 are compared (step S251). If C0 ≧ GridCscr1 is set, the value of C0 is set in Cno (step S252). If C0 <GridCscr1 is set, the value of GridCscr1 is set in Cno (step S253).
[0186]
As a result, the column number of the column to be drawn at the left end of the scroll item drawing area 223 of the logical view area 220 is set to Cno. That is, when the leftmost column selected on the column name list control 301 is a column within the display range, the column number of that column is set in Cno, but when the column is outside the display range Is set to Cno as GridCscr1 (the column number of the column currently displayed at the left end specified by the jump scroll operation). Note that this is just one example, and another example is possible.
[0187]
Next, the above-described W click column display switching method of FIGS. 25 and 26 is called with Cno as an argument (step S254). As a result, the display data of the columns after the leftmost column selected by the W click operation and designated for display within the display range (Columns where ColmStTbl [C] .ShowFlgW is “True”) are displayed. Are drawn in the scroll item drawing area 223 of the logical view area 220 only. Then, the columns after the leftmost column selected by the W click operation, and even in the display range, the column designated as non-display (ColmStTbl [C] .ShowFlgW is “False”. Display data in a certain column) is not drawn. As a result, among the columns that were within the display range, the columns that were designated to be hidden from the display designation disappeared from the screen, and conversely, the columns that were designated to be hidden from the designation of display are redisplayed. In this case, the columns are displayed left justified.
[0188]
If the display / non-display designation is changed only to the left column from the display range, the table display is not changed, and the display form of the column name list control 301 is changed. It only changes according to the result (only the display color of the column name of the column whose display / non-display designation has been changed is changed).
[0189]
Following step S254, the above-described display area determination routine of the column in FIG. 15 is called (step S255). As a result, ColmStTbl [C]. DispAreaFlg is set. That is, ColmStTbl [C]. ShowFlgW and ColmStTbl [C]. ShowFlgS is examined and ColmStTbl [C]. Of the scroll column within the display range. DispAreaFlg is set to “True”. That is, a new display range is set.
[0190]
Subsequently, the existing selection cancel routine of FIG. 19 described above is called (step S256). As a result, ColmStTbl [C]. SelectAreaFlag is set to “False”. That is, the currently selected column is canceled.
[0191]
Next, the above-described column name list control display routine of FIG. 16 is called (step S257). Thereby, for example, a screen 500 as shown in FIG. 30 is displayed. The screen 500 is displayed when “gross profit” and “gross ratio” are set to “hidden” in the initial screen 300 of the table of FIG. 28 by the mouse drag and drop operation and W click similar to the operation shown in FIG. This is a screen 500 displayed on the screen.
[0192]
In this case, as shown in FIG. 30, on the screen 500, the “gross profit” and “gross rate” columns disappear from the display of the table on the initial screen 300, and the “purchase number” column is followed by “ The columns after “Stock Number” are displayed. In accordance with such a change in the display of the table, the display form of the column name list control 301 also changes. That is, the display of “gross margin” and “gross margin” changes from black characters to white characters. Also, on the screen 500, since the columns from “sales” to “March” are displayed in the scroll area of the table and the display range has changed, the upper and lower frames of the column name list control 301 are displayed. The solid line display is extended from the “product name” to the column name “March”.
[0193]
Therefore, the user browses the display of the column name list control 301 on the screen 500, and is not displayed on the screen, but actually, between the “number of purchases” and “stock quantity” columns, It can be recognized from the display form of the column names that there are “Rice” and “Roughness”. Further, from the display form of the frame line, it can be immediately known that “02 month” and “01 month” are partially displayed or not displayed on the screen 500.
[0194]
On the screen 500, the “gross profit” and “gross profit” and “gross profit” column names on the column name list control 301 on the initial screen 300 are again performed by dragging the mouse and performing a W click operation. The “roughness ratio” column is designated as “display” again, and the display on the display device 90 is switched from the screen 500 to the screen 300.
[0195]
As described above, in this embodiment, by performing a mouse drag operation and a W click operation on the column name list control 301, a plurality of consecutive columns are changed from “display” to “hide” at a time, or It can be changed from “non-display” to “display”. In addition, by directly W-clicking a single column name on the column name list control 301 without dragging, it is possible to designate display / non-display of a single column.
[0196]
FIG. 31 is a block diagram showing a hardware configuration of a computer 600 that implements the above embodiment.
The computer 600 includes a CPU 601, a ROM 602, a RAM 603, an external storage device 604, a recording medium driving device 605, an input / output device 607, and a communication interface 608 connected to the CPU 600 via a bus 609.
[0197]
The CPU 601 can access each of the components 602 to 608 via the bus 609 and controls the entire system. A program that implements the algorithm of the embodiment of the present invention is stored in, for example, the ROM 602, the external storage device 604, or the portable recording medium 606.
[0198]
The program stored in the ROM 602 or the external storage device 604 is expanded on the RAM 603 in a format that can be executed by the CPU 601 and executed by the CPU 601. The program stored in the portable recording medium 606 is read by the recording medium driving device 605 when the portable recording medium 606 is mounted on the recording medium driving device 605, and the CPU 601 stores the program on the RAM 603. It is expanded into an executable format and executed by the CPU 601.
[0199]
The program may be held by an information provider 800 connected to the computer 600 via the network 700. In this case, the communication interface 700 is connected to the information provider 800 via the network 400. The stored program is downloaded to the external storage device 604. The program downloaded to the external storage device 604 is executed by the CPU 601 by the method described above.
[0200]
The input / output device 607 corresponds to the input device 90 and the display device 80 in FIG. 1, and a user inputs a command for initial display of a table on the display screen of the input / output device 607 and a table column displayed on the screen. This is used for a mouse operation or the like for the name list control 301. In addition, a table is displayed according to the mouse operation or the like.
[0201]
The external storage device 604 corresponds to the external storage device 110 in FIG. The RAM 603 corresponds to the table information table 10, the display memory 30, the display attribute table 40, the column width information table 50, the column name list data buffer 60, and the like in FIG. In the RAM 603, registers 71 to 74, a work area for the CPU 601, and the like are secured.
[0202]
If the information provider 800 includes a computer that can execute the program and an external storage device that stores the table information table 10, the user can remotely execute the program from the input / output device 607. It is also possible to remotely execute the above program on a computer owned by the information provider 800 via the communication interface 608 and the network 700 by inputting a command for executing the command. In this case, the display data of the table and column name list control 301 obtained by the computer owned by the information provider 800 can be received by the computer 600 via the network 700 and the communication interface 608. The displayed data is displayed from the input / output device 607 in a format that can be viewed by the user.
[0203]
The portable recording medium 606 is a floppy disk, CD-ROM, CD-RAM, various standards DVD, magneto-optical recording or phase change type optical disk, IC card, or the like. The external storage device 604 is a hard disk, a disk array, or the like. The input / output device 607 is a pointing device such as a keyboard or a mouse, and a thin display such as a CRT display, a liquid crystal display, a plasma display, or an organic EL (Electro Luminescence) display.
[0204]
The network 700 is a LAN, MAN, WAN, the Internet, or the like.
In the above-described embodiment, the operation target is a column. However, the present embodiment can be applied to realize a row display suppression or a row jump scroll operation. In this case, the row name list control is displayed as corresponding to the column name list control 301. In a hierarchical table with a large number of rows, such as a bundling table, the names of all items are displayed for items in the upper layer such as large items and medium items, and lower layers such as small items. For the item, only the representative item name (for example, the top item name) may be displayed on the line name list control.
[0205]
In this embodiment, the column name list control 301 is displayed on one line. However, the number of rows of the column name list control 301 may be changed as appropriate according to the number of columns in the table. Even in this case, it is preferable that the display order of the column names correspond to the order of the columns in the table. Further, when selecting a plurality of columns, a plurality of discrete column names may be selected instead of a plurality of consecutive columns. The present invention can also be applied to tree structure display references that do not fit on one screen, such as file directories. In this case, for example, a list of each hierarchy name is displayed, and the hierarchy name is selected.
[0206]
In the present embodiment, the display format of the table can be changed by designating the non-display of the column, so that the original table can be processed on the screen to create a table of various formats. Therefore, it is possible to adopt a configuration in which the table obtained by this processing can be stored. Implementation of the various modifications as described above can be easily conceived by those skilled in the art from the present embodiment.
[0207]
【The invention's effect】
According to the first aspect of the present invention, when displaying table data composed of a plurality of columns, a list of all column names of the table data is displayed on the same screen in parallel with the display of the table data. Thus, column names that are not displayed on the display screen can be confirmed on the column name list on the same screen as the table data. That is, it is possible to intuitively grasp the entire configuration of the table simply by looking at the display of the column name list. And since all the column names that are displayed as the table data on the screen and the column names that are not displayed are also displayed in the column name list, the column to be scrolled including the columns that are not displayed on the screen is specified. It is possible to confirm and change the scrolling column reliably and quickly. Further, as a result of the scroll display, it can be intuitively confirmed on the list of column names on the same screen as the table data whether or not all columns of the table data are displayed on the screen.
According to the second aspect of the present invention, when displaying table data composed of a plurality of columns, all the column names of the table data are displayed on the same screen in parallel with the display of the table data. The column names that are not displayed on the screen are displayed on the same screen as the table data by displaying the list in the horizontal direction in such a way that the columns that are displayed and the columns that are specified to be hidden can be identified. It can be confirmed intuitively on the column name list. That is, by simply looking at the column name list, it is possible to intuitively grasp the overall configuration of the table data and whether or not each column constituting the table data is displayed based on the difference in display form. In addition, by specifying one or a plurality of column names on the column name list, the display / non-display state of the column of the table data can be changed for the specified column name, so that the user can perform a simple and speedy operation. Thus, the column display state of the table data can be controlled as desired.
