[Industrial application fields]
The present invention relates to a general-purpose screen display processing method for performing display control in a screen display control apparatus that controls screen display of a terminal having a man-machine interface.
The system equipped with this apparatus is, for example, a personal computer as a terminal connected by a LAN (local area network), and inputs data at a predetermined time at a predetermined place on a specific display screen, and a desired calculation result. It is used to facilitate the operation of a group (stores, markets, etc.) equipped with the system by obtaining information or using it for the judgment of collecting information.
[0003]
In such a system, an application program is provided to perform a predetermined operation while performing a predetermined display, receiving a desired data input, and the development of the application program corresponds to each group. is necessary.
By the way, with respect to display control in a system having a man-machine interface, in order to improve the applicability of a program created as an application and reduce the difficulty of the program, data related to display is separated as much as possible on a ROM (Read Only Memory). Stored and the application controls display with reference to the data.
[0004]
[Prior art]
Therefore, the application program is configured to refer to the data defined on the ROM. When executing the display control, the ROM is referred to for all data regardless of fixed data or variable data. Yes.
Here, the fixed data is data that does not change due to a display trigger or the like, and the variable data is data that changes according to a display trigger or the like and is set by inputting a value at a desired time. For example, FIG. ”And“ next page ”characters and the like are used as fixed data, and“ 94/08/20 ”characters and other data that can be changed are called variable data.
[0005]
[Problems to be solved by the invention]
However, such a conventional configuration has the following problems.
In other words, variable data must be arbitrarily controlled by the application, but fixed data is referenced by the ROM even though the application does not need to be aware of display changes. Creation becomes complicated.
[0006]
In addition, since the contents of the application include a ROM reference part related to display control of fixed data, it is necessary to use different applications depending on the hardware configuration, and it is difficult to divert the applications in different hardware configurations.
Furthermore, when the display control of fixed data is performed uniformly with variable data, the entire screen is redisplayed. Therefore, if a device with a slow display speed, such as an LCD display, is used as a display means, the response is redundant. The degree becomes high and a desired processing speed cannot be obtained.
[0007]
The present invention has been devised in view of such a problem. By performing management of variable items and fixed items by general-purpose display control processing, the amount of application program development work can be reduced, and in addition, It is an object of the present invention to provide a general-purpose screen display processing method in a screen display control device capable of improving display speed by suppressing redundancy during display.

In this embodiment, in the screen display control apparatus 1 for controlling the screen display of the terminal 3 having the man-machine interface as shown in FIG. 2, the data structure as shown in the schematic block diagram of FIG. Equipped with.
[0017]
That is, the screen data index tables 53 are prepared for the number of screens provided by the system, and the screen data index table 53 stores the storage address of the screen display data 54 corresponding to each screen.
The screen display data 54 is prepared for display elements in each screen, and the display type, display information, addresses of various display data 55 to 63 corresponding to the display type, and change item numbers are set for each element.
[0018]
Here, the display type is different from a character string, an icon, an underline, and a straight line, and the display information is set as data indicating presence / absence of display, presence / absence of reversal, and erasure.
As the change item number, “0 (not set)” is defined when the display content of the corresponding element is a fixed display item, and an independent arbitrary value within the same type is set for a variable display item. Can be done.
[0019]
When the display type of the screen display data 54 is a character string, the display data address of the screen display data 54 stores the address of the variable character string display data 55.
When the display type of the screen display data 54 is an icon, the address of the icon display data 61 is stored in the display data address of the screen display data 54.
[0020]
When the display type of the screen display data 54 is underlined, the display data address of the screen display data 54 stores the address of the underline display data 62.
When the display type of the screen display data 54 is a straight line, the display data address of the screen display data 54 stores the address of the straight line display data 63.
In order to operate these data for general purposes, as shown in the block diagram of FIG. 2, display initialization processing means 101, display control processing means 102, display release processing means 103, display character string change processing means 104, Display character string display setting processing means 105, display character string deletion setting processing means 106, display character string inversion setting processing means 107, display character string non-inversion setting processing means 108, display icon display setting processing means 109, display icon deletion setting processing Means 110, display icon inversion setting processing means 111, display icon non-inversion setting processing means 112, display underline display setting processing means 113, display underline deletion setting processing means 114, display straight line display setting processing means 115, display straight line deletion setting processing means. 116 and display screen erasure setting processing means 117 are provided.
[0021]
Each of these means performs an operation according to the flowcharts shown in FIGS. 11 to 33, whereby desired control is performed, and each data structure of FIG. 1 is configured by the operations shown in FIG.
Here, first, the control of each screen display shown in FIGS. 4, 6 (a), (b) will be described with reference to the flowcharts shown in FIGS. 5, 7, 8. The menu screen display in FIG. In step X1, display initialization processing by the display initialization processing means 101 is performed.
[0022]
The display initialization processing means 101 performs operations such as securing each storage area as will be described later along the flowcharts shown in FIGS.
Next, in step X2, a screen clearing operation is performed, and the display on the entire screen is erased.
In step X3, display control processing by the display control processing means 102 is performed.
[0023]
The display control processing means 102 displays each item as described later along the flowcharts of FIGS.
As a result, the screen display state shown in FIG. 4 is entered, and the input waiting state at the next step X4 is entered.
Thereafter, by selecting an icon corresponding to any of the items “ordering”, “introduction”, “reference”, “transmission”, “confirmation”, and “initial setting”, the corresponding process is performed in step X5. It is activated.
[0024]
Here, when the “order” icon is selected, display control up to the display of FIG. 6 is performed according to the flowchart of FIG.
First, in step Y1, display initialization processing by the display initialization processing means 101 is performed.
The display initialization processing means 101 performs operations such as securing each storage area as will be described later along the flowcharts shown in FIGS.
[0025]
Next, in step Y2, a screen clearing operation is performed, and the display is erased for the entire screen.
Then, in step Y3, it is determined whether or not there is a page transition. If “Yes”, step Y4 is executed through the “YES” route.
In step Y4, a screen editing process is performed by the operation according to FIG. 8, and each display is changed or erased as described later.
[0026]
On the other hand, when the “1/2” page shown in FIG. 6A is displayed in the initial state where there is no page transition, step Y5 is executed without executing step Y4 through the “NO” route. The
Thereby, the display control processing by the display control processing means 102 is performed for the initialized state in step Y1.
[0027]
Thereby, the display state of FIG. 6A is achieved, and the input waiting state in step Y6 is entered.
In step Y6, when vegetables are selected as shown in FIG. 6A, the vegetable data processing operation is started in step Y7, and other types of processing operations are started by selecting various items. The
[0028]
By the way, in the display of FIG. 6 (a), when the icon corresponding to “next page” is selected, there is a page transition. Therefore, the “YES” route is taken in step Y3, and the screen editing in step Y4 is executed. Thereafter, the display control processing by the display control processing means 102 in step Y5 is performed.
As a result, the display of the variable item is changed, the display page “1” is “2”, the data name “vegetables” is “drinks”, and the data name “meat” is “consumables”. The data names “fish” and “fruits” are erased, and each delivery date is changed to the corresponding date (see FIG. 6B).
[0029]
At this time, the display state of the fixed item other than the variable item is maintained as it is.
Now, the screen editing process in step Y4 will be described in detail. Each processing operation is performed according to the flowchart of FIG.
First, in step Z1, the display character string change processing operation by the display character string change processing means 104 is performed. Specifically, “1” of “1/2” is changed to “2” for the display page that is a variable item. The display character string changing process to be changed is performed.
[0030]
Next, it is determined whether or not there is display data in step Z2. If there is display data, the display character string changing operation is performed by the display character string changing processing means 104 in steps Z3 and Z4.
That is, in step Z3, a display character string changing process for changing the “vegetables” to “drinks” is performed for the data name that is a variable item.
[0031]
Further, in step Z4, a display character string changing process for changing the date name that is a variable item, specifically, “94/08/20” to “94/08/24” is performed.
Then, the number of display items is compared in step Z7, and the “NO” route is used until the operations in steps Z2 to Z4 are performed for all item display positions (four in the example of FIG. 6) on the same page. Is repeated.
[0032]
By the way, when it is determined in step Z2 that there is no display data (in the case of the third item position and the fourth item position on the next page in the example of FIG. 6B), step Z5 and step Z6 are executed. Through the operation of the display character string erasure setting processing means 106, the display character string is erased.
That is, in step Z5, the display character string related to the data name is deleted, and in the example of FIG. 6B, “fish” on the previous page at the third item position is deleted.
[0033]
In step Z6, the display character string related to the date is deleted, and in the example of FIG. 6B, “94/08/23” on the previous page at the third item position is deleted.
As for the display of the fourth item position, since the number of display items has not been reached, the character string erasing operation similar to the above-described third item position is performed through the “NO” route in step Z7 and the “NO” route in step Z2. Done.
[0034]
After such an operation, the icon inversion operation in step Z8 and step Z9 is performed.
That is, in step Z8, the display icon inversion setting processing by the display icon inversion setting processing means 111 is performed according to the flowchart of FIG. 27, and the inversion operation regarding the icon to be inverted at the time of the current display is performed.
[0035]
In the example of FIG. 6A, the icon inversion operation is performed for the item “vegetables” on the 1/2 page.
In step Z9, display icon non-inversion setting processing by the display icon non-inversion setting processing unit 112 is performed in accordance with the flowchart of FIG.
[0036]
In the example of FIGS. 6 (a) and 6 (b), when shifting to the 2/2 page, an operation of shifting the inverted icon for the item “vegetables” on the 1/2 page to the non-inverted state is performed. .
By the way, the operation of each processing means equipped to perform the above operation is performed as follows.
[0037]
First, the display initialization processing means 101 performs an operation according to the flowcharts shown in FIGS.
That is, in step A1 of FIG. 11, a screen display data changing area 58 for storing the screen display data 54 of the ROM 51 to be transferred is secured at a required portion in the RAM area 52 (see FIG. 3).
[0038]
In step A2, the screen display data 54 stored in the ROM 51 and linked to the screen data index table 53 is copied to the screen display data changing area 58, and the screen display data 54 in the RAM area 52 is changed. Operation becomes possible.
In step A3, the number of variable display character strings is calculated by referring to the display data address in the screen display data changing area 58.
[0039]
Next, in step A4, it is determined from the calculation result in step A3 whether or not there is a variable character string. If there is, the process for the variable character string in steps A5 to A9 is performed through the “NO” route. If not, step A10 and step A11 are executed without executing steps A5 to A9 through the “YES” route.
[0040]
First, in step A5, a character string display data changing area 59 for storing the variable character string display data 55 of the ROM 51 to be transferred is secured in a required portion of the RAM area 52.
In step A6, the variable total character string length is calculated by referring to the character data address in the character string display data changing area 59.
[0041]
In step A7, a character string data changing area 60 for storing the variable character string data 56 of the ROM 51 to be transferred is secured in a required portion of the RAM area 52.
In response to the above operation, the character string data link establishment process is performed as described later in step A8 along the flowchart shown in FIG.
[0042]
In step A9, whether or not to replace the character string display data is set.
In step A10, the display digit number storage area is secured by an operation according to the flowchart of FIG.
Further, in step A11, the icon inversion state storage area is secured by an operation according to the flowchart of FIG. 14 described later, and the display initialization process is completed.
[0043]
By the way, the above-described character string data link establishment processing is performed according to the flowchart shown in FIG. 12. First, in step B1, it is determined whether or not “change item number has been set?”. Steps B2 to B5 are executed through the route.
First, in step B 2, the variable data in the character string display data 55 is copied from the ROM 51 to the character string display data changing area 59 in the RAM area 52.
[0044]
In step B 3, the variable data in the character string data 56 in the ROM 51 is copied to the character string data changing area 60 in the RAM area 52.
Next, in step B4, a setting for linking the screen display data in the screen display data changing area 58 and the character string display data in the character string display data changing area 59 is performed.
[0045]
That is, the screen display data change area 58 (change area a) is searched, and the character string display data 55 in which the change item number is set is changed to another change area b (character string display data change area 59 in the RAM 52. ) To establish a link between the change area a and the change area b.
Further, in step B5, a setting for linking the character string display data in the character string display data changing area 59 and the character string data in the character string data changing area 60 is performed.
[0046]
That is, the change area c (character string data change area 60) for storing the display character string is acquired (step A7), and the link between the change area b and the change area c is established.
Then, in step B6, it is determined whether or not the processing for each display data has been completed, and the processing from step B1 to step B5 is repeated while the processing has not been completed.
[0047]
On the other hand, the display digit number storage area securing process described above is performed according to the flowchart shown in FIG. 13. First, in step C1, the number of changed character strings is acquired, and in step C2, the acquired result is referred to. A determination is made whether there is a change character string?
If there is a change character string, step C3 is executed through the “YES” route to secure the display digit number storage area.
[0048]
Next, in step C4, it is determined whether or not it is a variable character string. If it is a variable character string, a change item number is set.
In step C6, it is determined whether or not the change item number has been set for all the display modes, and steps C4 and C5 are repeated until each display mode is completed.
[0049]
By completing the setting of the change item number, the display digit number storage area securing process is completed.
The icon inversion state storage area securing process described above is performed according to the flowchart shown in FIG. 14. First, in step D1, the number of changed icons is acquired. In step D2, referring to the acquisition result, “ A determination is made whether there is a change icon?
[0050]
If there is a change icon, step D3 is executed through the “YES” route to secure the icon inversion state storage area.
Next, in step D4, it is determined whether or not it is a variable icon. If it is a variable character string, a change item number is set.
Then, in step D6, it is determined whether or not the change item number has been set for all display modes, and steps D4 and D5 are repeated until each display mode ends.
[0051]
  When the change item number setting is completed, the icon inversion state storage area securing process is completed.
  By the way, the display control processing by the above-described display control processing means 102 is performed by the respective operations according to the flowcharts of FIGS. 15 to 18. First, in step E1 in FIG.ChangeThe item numbers are initialized, and it is determined in step E2 whether each display mode is set.
[0052]
  If each display mode is not set, a display execution process is performed in step E3, and an operation according to the flowchart of FIG. 16 is performed as described later, and each display is performed.
  When the display execution process ends, in step E4ChangeAfter the item number is updated, the execution process for the next display mode is repeated.
[0053]
By the way, the above-described display execution process is performed in accordance with the flowchart of FIG. 16. First, the presence or absence of display is confirmed in step F1, and when there is a display, each operation from step F2 and step F3 to step F6 is performed.
That is, along the branch for each display mode in step F2, when the display mode is character string display, the character string display control in step F3 is performed. In the case of icon display, the icon display control in step F4 is underlined. If the underline display operation in step F5 is a straight line display, the straight line display operation in step F6 is performed.
[0054]
Then, in step F7, an operation for resetting the presence / absence of display to “none” is performed, and the display execution process ends.
Here, in the character string display control described above, an operation according to the flowchart of FIG. 17 is performed. First, in step G1, it is confirmed whether or not “display is present”.
[0055]
When there is a display, step G2 is executed through the “YES” route, and a character string is displayed.
That is, as shown in FIGS. 9A and 9B, when “XYZW” is displayed this time when the previously displayed character string is “ABC”, the number of characters displayed this time is larger than the previous time, so “ABC” is displayed. “XYZ” is overwritten and “W” is overwritten in the space after “C”.
[0056]
Next, step G4 is executed. In the case of “no display” in which the “NO” route is taken in step G1, the character string length is set to “0” in step G3 without displaying the character string in step G2. After step S4, step G4 is executed.
Therefore, since items that are not displayed are not displayed, the redundancy of display processing is reduced when there is little change in the display content on the screen, such as during page transitions. it can.
[0057]
  In step G4, the previous display character string length is acquired and referenced. In step G5, the previous character string length is compared with the current character string length. If the previous character string length is large, step G6 is executed. Executed.
  In step G6, the coordinates of the unnecessary character string portion are calculated and the rectangle is cleared.
  This operation is shown in FIGS.cIn this case, in this case, “XYZ” is used as the display character string for the previous display character string “ABCDE”.
[0058]
Although “XYZ” displayed this time is overcoated on the previously displayed character string, “DE” displayed last time remains. The operation of deleting this unnecessary character string is performed by rectangle clear.
This rectangle clear is performed by the clear operation in the drawing mode, and is not performed in the character-based space character display. That is, in the character-based space character display, it is necessary to search, read, and draw the space character from the kanji ROM, and the processing speed is low. Since the processing speed for clearing is much higher, a rectangular clearing means is used.
[0059]
As a result, redundancy for erasing unnecessary character strings is suppressed, the processing speed is improved, and a particularly large effect is obtained in an LCD display or the like having a slow display speed.
In the icon display control described above, an operation according to the flowchart of FIG. 18 is performed. First, in step H1, whether or not “display is present” is confirmed.
[0060]
Then, if there is a display, steps H2 to H6 are executed through the “YES” route, and an icon is drawn.
First, step H2 is executed, and the inverted state is acquired for the previous icon. Using this acquisition result, a comparison is made with the current inversion state. If “inversion state does not match”, the inversion state should be canceled, so step H5 is executed through the “YES” route. The rectangle of the icon is cleared.
[0061]
Thereafter, in step H6, an icon is drawn, and a required icon display state is reached.
By the way, if the inversion states of the icons match, the operations of Step H5 and Step H6 are not performed by going through the “NO” route from Step H4, so that all icons are cleared and redrawn. Compared to the case, the processing speed can be greatly improved.
[0062]
If no icon is displayed, step H3 is executed from the step H1 through the “NO” route, and an icon rectangle clear operation is performed.
In this way, when the display control processing means 102 is activated, the display area 58 of the designated change area a is referred to, and after the display according to the set data is performed, the change area for each item is displayed. Whether or not to display the screen display data 58 existing in a is set to no display. This is an operation for not displaying items for which the presence / absence of display is not displayed later.
[0063]
When each character string is displayed, the current display character string length is compared with the previous display character string. If the current character string is shorter, the coordinates of the area corresponding to the difference are calculated and the rectangle is cleared.
Furthermore, when each icon is displayed, the previous inversion state and the current inversion state are compared, and only when the icons are different, the icon is redrawn.
[0064]
Then, the display release processing means 103 will be described. The processing operation in accordance with the flowchart shown in FIG. 19 is performed. First, in step I1, a determination of “replacement?” Is made. Steps I2 and I3 are executed.
In step I2, the variable character string storage area 60 is released, and in step I3, the variable character string display data storage area 59 is released.
[0065]
Then, Step I4 is executed, and the screen display data changing area 58 is released.
If there is no replacement in step I1, step H4 is executed through steps “NO” without executing steps I2 and I3, and the screen display data changing area 58 is released.
[0066]
That is, when the display release processing unit 103 is activated, the change areas a, b, and c on the RAM secured by the display initialization processing unit 101 are released, and the display control on the screen ends.
Next, the operation of the display character string change processing means 104 will be described. The operation is performed in accordance with the flowchart shown in FIG. 20. First, the data search for the changed character string is performed in step J1, and the instruction character string is determined in step J2. Settings are made. Next, in step J3, the presence / absence of a display presence / absence flag is set.
[0067]
As a result, the display data presence setting is made when determining the presence or absence of the display data in step Z2 in FIG.
That is, when the display character string change processing means 104 is activated, the character string display data corresponding to the designated change item number is searched in the change area b, and the linked character string is copied to the change area c. Further, an operation for setting the display presence / absence flag of the corresponding screen display data 2 to display is performed.
[0068]
Then, the operation of the display character string display setting processing means 105 will be described. The operation is performed in accordance with the flowchart shown in FIG. 21. First, the data search for the changed character string is performed in step K1, and then the presence or absence of display in step K2. The flag is set.
Thus, the display presence setting is performed when the display control processing unit 102 determines whether or not to display.
[0069]
That is, when the display character string display setting processing unit 105 is activated, the screen display data 2 whose display type is a character string is searched in the change area b corresponding to the designated change item number, and the display presence / absence flag is set. Set to display.
The operation of the display character string erasure setting processing means 106 will be described. The operation is performed in accordance with the flowchart shown in FIG. 22. First, the data search for the changed character string is performed in step L1, and then the presence or absence of display in step K2. Flag erasure is set.
