[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device capable of efficiently scrolling a table drawn on a display device of a numerical control device.

[0002]

2. Description of the Related Art FIG. 10 is a block diagram showing an example of a device for implementing a conventional scroll function. Less than,
The function of each unit will be described with reference to FIG. The scroll management unit 105 determines a key input from the keyboard 101 via the input control unit 102, causes the screen creation unit 112 to create a screen for which scrolling has been performed, and the display control unit 1
Output to the CRT 104 via 03. The scroll area storage unit 106 stores the leftmost column (top row) number DRMIN (DCMIN) and the rightmost column (bottom row) of the column (row) that is actually displayed in the horizontal (vertical) scroll area.
The number DREND (DCEND) and the number D of the rightmost (bottom) column (row) of the completely displayed columns (rows)
RMAX (DCMAX) and the coordinate value of the region to be horizontally (vertically) scrolled are stored, and these data are referred to and changed by the scroll management unit 105. The virtual table storage unit 107 is a virtual table that is not affected by the table output on the screen, and stores the width of columns, the height of rows, the data to be displayed, the position of the data to be displayed within the cell, and the like. When the row number and column number of the virtual table are input, those data are output. FIG. 14 shows a conceptual diagram of such a virtual table. The numbers above this table show the column numbers, and the numbers on the left show the row numbers. Also, the screen creation unit 112
Is the row number, column number, and the coordinate value of the cell,
Obtaining necessary data from the virtual table storage unit 107, outputting the elements or ruled lines in the table via the display control unit 103,
Display on the CRT 104.

The operation of such a configuration is shown in FIG.
This will be described with reference to the flowchart of FIG. 1 and the screen example of FIG. However, assuming that the columns are from the 1st column to the Nth column and the rows are from the 1st line to the Mth line, the shaded portion of FIG. 12A is the portion actually displayed on the screen. Also, regardless of the scrolling state, cells are displayed with good separation between the upper end and the left end of the table. FIG. 12A shows the first screen state, and displays the third to a part of the eighth column and the second to a part of the seventh line. First, the number DRMI
N, DRMAX, DREND, DCMIN, DCMA
Initialize X and DCEND, wait for key input from the keyboard 101 (step S11), and end when the end key is input (step S12). If the end key is not input in step S12, the type of key input is determined (step S13). First, the operation when the right arrow key is pressed to scroll the table to the left will be described. When the right arrow key is input from the keyboard 101, it is determined whether there is room for scrolling to the left (step S23). If there is no room, the process returns to step S12. If there is room, the DRM
Scroll left by the width of the IN column. Width W of the leftmost DRMIN column in the horizontally scrollable columns being displayed
A region from the (DRMIN + 1) th column to the DRMAX column is calculated as the copy source region based on (DRMIN) and the coordinate value of the region to be horizontally scrolled (the hatched portion in FIG. 12B, step S25). W (DRMI
Only N) is copied to the left (step S26), and it is moved to the left end of the horizontally scrolled area (hatched portion in FIG. 12C). Then, the number DREND is updated (step S2
7) In the column loop (step S28), the newly exposed columns, ie, the elements from the (DRMAX + 1) th column to the DREND column and the vertical ruled lines are drawn (step S2).
9, S30). The shaded area in FIG. 12 (d) shows the area to be drawn. Then, after exiting the loop, a horizontal ruled line is drawn (step S32), and the number DRMAX is set.
Is updated (step S33), the number DRMIN is incremented by 1 (step S34), and the process returns to step S12 to wait for a key input.

Next, the operation when the left arrow key is pressed to scroll right in step S13 will be described. First, it is determined whether or not there is room for scrolling (step S14), and when there is room for scrolling, scrolling to the right is performed. The scroll size is the first (DRMIN
-1) The width of the column is W (DRMIN-1). DRMI
The copy source area is calculated based on the width from the Nth column to the DRMAXth column and the coordinate value of the scrolled region (step S16). The shaded area in FIG. 13A shows this copy source area. Then, this area is set to W (DRMIN
-1) is copied rightward and inside the horizontally scrolled area (step S17), and moved to the right end of the horizontally scrolled area (hatched portion in FIG. 13B). Then, subtract one from the number DRMIN (step S1
8), the number DREND is updated (step S19), and the exposed element of the DRMIN column and the ruled lines in the vertical and horizontal directions are drawn (step S20). The shaded portion in FIG. 13C shows this newly drawn portion. After that, the number DRMAX is updated (step S21), a vertical ruled line is drawn (step S22), and the step S12 is performed.
Return to and wait for key input. The vertical scroll is also performed in the same manner as the horizontal scroll.

[0005]

In the conventional scroll device, in order to realize a column (row) that does not scroll, the column (row) must be separately displayed outside the table, so that the scroll is performed in the vertical direction. The line that does not scroll and the line that does not scroll horizontally cannot be set at the same time.
For this reason, it is not possible to realize a table that has title columns in both rows and columns and can be scrolled vertically and horizontally. In addition, it was not possible to always display an arbitrary column or row regardless of the scroll state by the operator's instruction, so the column (row) that is the reference for comparison and the other column (row) are not displayed. For comparison, scrolling had to be repeated, and operability was poor. The present invention has been made under the circumstances as described above, and an object of the present invention is to provide a scroll device capable of always displaying an arbitrary column or row regardless of a scroll state by an operator's instruction. To provide.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a table scrolling device in a numerical controller having a function of displaying data in a table format. The above object of the present invention is to prevent horizontal scrolling in the table. This is achieved by providing column specifying means for specifying a column, row specifying means for specifying a row in the table that is not vertically scrolled, and means for performing horizontal scrolling and vertical scrolling except for the specified area.

[0007]

In the scroll device according to the present invention, rows or columns which are not scrolled can be arbitrarily set in the table, so that the comparison for each row or column can be performed easily and quickly. Further, since the title column can be set for both the row and the column, the title can always be seen regardless of the position of the displayed row or column, and the contents can be easily understood.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing an embodiment of the present invention, in which the same elements as those in FIG. 10 showing a conventional device are designated by the same reference numerals and the description thereof is omitted. Hereinafter, the function of each unit will be described with reference to FIG. However, it is assumed that columns that are not horizontally scrolled are collected on the left side of the table, and rows that are not vertically scrolled are collected above the table. Matrix number correspondence table 110
Stores the relationship between the column (row) number of the table that is actually displayed and the column (row) number of the table that is virtually held by the virtual table storage unit 107. When the column (row) number of the existing table is input, the column (row) number of the virtually owned table is output. This table can be rewritten from the area management unit 108. Also, the virtual table conversion unit 111
When the column number and the row number of the table actually displayed are input, outputs the display data of the corresponding column number and row number in the virtual table, the width of the column, the height of the row, and the like. Fixed area storage unit 1
The column 09 stores the number DRL (DCL) of the rightmost (bottom) column in the columns (rows) that are not horizontally (vertically) scrolled and the coordinate values of the region that is not horizontally (vertically) scrolled.
The area management unit 108 operates the scroll area storage unit 106, the fixed area storage unit 109, and the matrix number correspondence table 110 according to a key input from the keyboard 101, and then instructs the scroll management unit 105 to scroll. . Further, the column or row to be displayed on the screen and the coordinate values thereof are instructed to the screen creation unit 112, and the screen table is rewritten.

In such a configuration, the operation is shown in FIG.
This will be described with reference to the flowchart in FIG. Note that the same steps as the processing steps in FIG. 11 are designated by the same reference numerals, and the description thereof will be omitted. The flowchart of FIG. 2 is different from that of FIG. 11 in that the determination condition (step S42) in the process of determining whether there is a margin to scroll and the number DRL are also initialized in the initialization process (step S41).
The points are different. Next, a flow of processing when horizontal scrolling is prohibited will be described with reference to the flowchart of FIG. 4, the screen example of FIG. 3 and the matrix number conversion table of FIG.
In the example of FIG. 3A, horizontal scrolling is prohibited in the first column, horizontal scrolling is performed in the second and subsequent columns, and a ▼ mark indicates a scrollable range. 3A to 3D, the numbers around the table are added for convenience of description, and are not actually displayed on the screen. In addition, in FIGS. 5A to 5C, for convenience of description, it is assumed that the column width and the row height are constant, and there is no column or row displayed halfway at the left end or the lower end. And the number DREND are always equal, the number DREND is omitted. When the "fixed column setting" function key is pressed in the state of FIG. 3A, the display of the function key is changed (step S51), and the position and size of an appropriate column in the horizontal scrollable area are changed. A long cursor is calculated and displayed vertically (step S52), and it is determined whether the end key is pressed (step S53). If the end key is not pressed, the right or left arrow key is pressed. The cursor is moved and the column number when the return key is pressed is set to CP (step S54). The cursor can move only in the horizontally scrollable area. 3B shows the state of the screen immediately before the return key is pressed, and FIG. 5A shows the state of the conversion table at this time. Here, FIG.
F (i) represents the column number of the virtual table corresponding to the displayed column number i, and the horizontal scroll prohibited area is a set of columns that are constantly displayed on the screen without horizontal scrolling. The scroll area is a set of columns that are horizontally scrolled while being displayed on the screen, and the horizontal scrollable area is a set of columns that is horizontally scrolled regardless of whether they are displayed on the screen.

Next, the column in which the cursor is displayed is set as a horizontal scroll prohibited column and moved to the horizontal scroll prohibited area. In the procedure, first, the column number in the virtual table of the CPth column is saved in TEMP (step S55), and the matrix number correspondence table is rearranged in the matrix number correspondence table change loop (step S56). That is, from the (DRL + 1) th column to the front of the column where the cursor is, shifts to the right one by one (step S
57), after the loop ends, the column number in the saved virtual table is added to the end of the horizontal scroll prohibited column (step S58). FIG. 5B shows a conceptual diagram of this operation. Then, the cursor is once deleted (step S5
9), the number DRL and the number DRMIN are each incremented by 1 (step S60), and the DRL column and the DR
Elements from the MIN column to the CPth column and ruled lines are drawn (step S61), and the process returns to step S52. Figure 5
(C) shows the state of the matrix number correspondence table at this time.
If the end key is pressed in step S53, the vertically long cursor is erased (step S62),
The function key is returned to the state before entering this mode (step S63), and this mode ends.

Next, the flow of processing when canceling the horizontal scroll prohibition will be described with reference to the flowchart of FIG. 7, the screen example of FIG. 6 and the matrix number conversion table of FIG. Note that in FIG. 6A, the first column and the second column are columns that do not horizontally scroll. When the "release column lock" function key is pressed in the state of FIG. 6A, the display of the function key is changed (step S71), and the position and size of an appropriate column of the horizontal scroll prohibited area are calculated. A cursor is displayed (step S72). Here, it is determined whether or not the end key is pressed (step S73). If the end key is not pressed, the cursor is moved according to the right or left arrow key, and when the return key is pressed, The column number is designated as CP (step S74). However, the cursor does not stick out of the horizontal scroll prohibited area. 6B shows the state of the screen immediately before the return key is pressed, and FIG. 8A shows the state of the matrix number correspondence table at this time. Next, the matrix number correspondence table is changed to move this column to the horizontally scrollable area. The procedure is as follows. First, the column number f (C
(P) is saved in TEMP (step S75), and in the matrix number correspondence table change loop (step S76), the (CP +)
1) The columns from the (DRL + TEMP-2) th column are shifted to the left one by one (step S77), and after the loop ends, the column where the cursor is displayed is moved to the position corresponding to the virtual table (step S78). By this processing, f (i)
Will always be sorted in ascending order for i = DRL + 1, ..., N. FIG. 8B shows a conceptual diagram of this operation, and FIG. 8C shows a changed matrix number correspondence table. Then, the vertical cursor is erased from the screen (step S79), the number DRL and the number DRMIN are each decreased by 1 (step S80), the number CP and the number DR are added.
MAX and number DREND are updated (step S8)
1). All the finally displayed columns, that is, the first column to the DRL column and the DRMIN column to the DRMAX column are redrawn, and the operation from step S72 is repeated. If the end key is pressed in step S73, the cursor is erased (step S8
3) The display of the function keys is changed (step S84), and this mode ends. 6C shows the state of the screen immediately before the end, and FIG. 6D shows the state of the screen immediately after the end. Further, the setting and cancellation of the vertical scrolling prohibition of the row are performed in the same manner as the column.

On the other hand, FIG. 9 shows an example of a screen according to the present invention. In FIG. 9 (a), there are more lots than the displayed number, and the items are displayed, in addition to the delivery date, the processing status, etc. There is an item. Further, the first column is displayed with horizontal scrolling prohibited and the lot name is displayed, and the first row is displayed with vertical scrolling prohibited and item name is displayed. Therefore, even if you scroll horizontally to display other items, or vertically scroll to display other lots, the lot name and item name are always displayed regardless of the scroll position. There is. However, even if the user horizontally scrolls as it is, it is not possible to simultaneously display the data such as the scheduled start date of processing, the delivery date, and the processing status. However, if horizontal scrolling is prohibited for the scheduled processing start date row, by scrolling the other rows horizontally, data such as delivery date and processing status that are not currently displayed and processing start are displayed as shown in Fig. 9 (b). The scheduled date can be displayed at the same time for comparison. Of course, vertical scrolling is possible except for the first row, so this display is possible for all lots.

[0013]

According to the present invention, useless scrolling operations can be avoided, and comparison can be performed for each row or column of a table quickly and reliably, so that operability can be improved and operation time can be shortened. .
