Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen control device for creating a screen on a computer or the like.

[0002]

2. Description of the Related Art Conventionally, when creating a screen for display on a computer or the like, a screen creator fixedly determines an actual screen layout and creates the screen.
For example, when there are a plurality of fields and the screen is laid out, the screen creator determines the line / column position of each field one by one and creates the screen.

[0003]

However, in the above-described conventional screen creating method, for example, text information, input field information, and the like are identified in advance as elements for performing screen layout, and the screen creator creates the screen layout. It is a heavy burden for the screen creator because they must be arranged while considering each one.
Also, since one system usually has multiple screens, it is necessary to unify the layout images of each screen systematically. Therefore, if you want to add field information etc. to a certain screen, layout the entire screen. You have to consider it from the beginning. As a result, even if a small element is changed, a large screen change may occur, and from this point of view, the screen creator's burden is large.

As described above, conventionally, when a screen is created,
Since the burden on the screen creator is large, a screen control device capable of reducing the burden has been desired.

[0005]

The screen control device of the present invention prepares a group information file, a field information file, and a screen information file in order to solve the above-mentioned problems. The group information file is an information file that shows in which groups the positions of the multiple fields displayed on the screen are laid out, and the field information file includes the shape of the fields and each field in the multiple fields. It is an information file indicating the priority of the display position of. Further, the screen information file is an information file provided corresponding to each screen and having group information indicating which group each screen belongs to and field information indicating which field is configured. . Then, in response to the screen configuration request, the requested screen is retrieved from the screen information file, and corresponding information is retrieved from the group information file and the field information file based on the group information and field information shown in this screen information file. A screen forming unit for forming a screen requested by these information is provided.

[0006]

In the screen control device of the present invention, when a screen configuration request is made to the screen forming unit, the screen forming unit
First, based on the screen number requested for the screen configuration, the information of the corresponding screen is taken out from the screen information file. Next, the corresponding group information file is specified from the group information shown in the screen information file, and the corresponding field information file is specified from the field information. Then, the screen forming unit forms a screen based on the contents of the group information file and the contents of the field information file.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a system configuration diagram showing an embodiment of a screen control device of the present invention. The system shown in the figure has a registration screen control information section 4 including a group information file 1, a field information file 2 and a screen information file 3, a screen forming section (screen generator) 5, an operation library 6, an operating system (OS) 7, It is composed of a display screen 8 and an application program (AP) 9.

The registration screen control information section 4 is composed of a storage device such as a magnetic disk device or a semiconductor memory, and the group information file 1 is laid out in which positions a plurality of fields displayed on the screen are laid out. It is a file that shows whether or not it is divided into groups. The field information file 2 is a file showing the shape of the field and the priority of the display position of each field. Further, the screen information file 3 is provided corresponding to each screen, and group information indicating which group each screen belongs to,
It is a file that shows which fields are configured.

The screen forming section 5 also includes an operation library 6
A screen configuration request is accepted via the screen information, the requested screen is taken out from the screen information file 3, and the group information file 1 and the field information file 2 are based on the group information and field information shown in the screen information file 3. Further, it has a function of extracting corresponding information and forming a requested screen by these information.

The operation library 6 is based on a screen forming request from the application program 9 and the screen forming unit 5
It is a library having a function of requesting screen formation to the. The operating system 7 is an operating system that is the basis of software as a system, and the operation library 6 operates on the operating system 7. Further, the display screen is a display such as a CRT for displaying the screen formed by the screen forming unit 5 via the operation library 6 and the operating system 7.

The application program 9 is, for example, a program for various processes of a financial institution, and when a screen display request is made, it makes a screen forming request to the screen forming section 5 via the operation library 6. .

Next, details of the registration screen control information section 4 will be described. 2 to 4 are diagrams showing the format of each file of the registration screen control information section 4. FIG. 2 shows the format of the group information file 1, FIG. 3 shows the format of the field information file 2, and FIG. 4 shows the format of the screen information file 3. Shows. Also,
FIG. 5 is an explanatory diagram of a coordinate configuration in screen creation,
(A) shows screen coordinates and (b) shows field coordinates.

First, as shown in FIG. 2, the group information file 1 is managed by a group name and is composed of base screen information, layout control information and the like. The base screen information includes a display position, a screen size, bitmap information, scroll bar information and the like. The display position refers to the upper left corner of the display screen shown in FIG.
This is position information of the base screen defined in y1). Further, the screen size indicates the size of the base screen, and (x
2, y2). Further, the bitmap information is information including image data and the like, and is composed of the number of bitmaps and bitmap information. The display position on the screen is defined by (x3, y3) with the upper left of the screen portion as a reference point. The scroll bar information is information indicating whether there is a vertical scroll bar or a horizontal scroll bar in the screen.

The layout control information includes fixed information and variable information, and the fixed information can fix the display position in field attribute units. Also,
The variable information indicates control information (rule) for automatically laying out other than fixed fields, and is composed of a display start position, a horizontal number of fields, layout control (rule), and the like. As described above, the group information file 1 defines a group for unifying the screen layout images, and thus the screen layout can be controlled in group units.

Next, the field information file 2 is shown in FIG.
As shown in, all attributes are set in the fields.
By performing the same control for each attribute, it is possible to perform the same control for the ones having the same field contents, thereby realizing a systematically unified work environment.

Field information includes field attributes, overall priority, text information, EDIT information, and other information. The overall priority order is for determining the layout order of fields laid out from the upper left of the screen, and different orders are set for all attributes. The coordinate position of the field is defined with the upper left of the logical coordinate portion of FIG. 5B as the reference point, (L1, M1) as the text information, and (L2, M2) as the coordinate position of the EDIT information. In addition, with the field here, all the shaded portions including text information, EDIT information, and other information are recognized as one field. That is,
The screen forming unit 5 performs automatic screen layout control for each field.

As shown in FIG. 4, the screen information file 3 is an information file unique to each screen managed by the screen number, and has the screen number, priority group information, field information and the like.

The priority group information enables layout control in the order of the group having the highest priority. Group control is merged in consideration of the priority and the merged group information is used as new group information. Can be used for layout control.

The field information in the screen information file 3 is information unique to the screen. Here, the number of fields is the number of fields on the corresponding screen, and field information exists for each field. The field attribute sets an attribute existing in the field information file 2, and the same-attribute priority order indicates a priority order when a plurality of same-attribute fields exist in the same screen. Further, the text information, the EDIT information, and other information have a function as a control designating unit, and set only items to be controlled different from the setting in the field information file 2, and other than that, NULL (empty character) or X '. F
Set F '.

When the NULL is set, layout control is performed according to the control information in the field information file 2. Also, when X'FF 'is set, it is determined that there is no control of the corresponding item.

Next, the operation of the screen control device will be described. FIG. 6 is a flowchart of the automatic screen layout control operation by this apparatus. The AP specifies the screen number for control of the screen, and requests the screen forming unit 5 to perform screen display control and the like by the operation library (step S
1). The screen forming unit 5 determines the corresponding screen based on the screen number, and acquires screen information (priority group information, field information, etc.) corresponding to the screen number from the screen information file 3 (step S2).

Next, the group information corresponding to the group name in the priority group information is acquired from the group information file 1 (step S3). Then, it is determined whether or not the number of priority group information is 1 (step S4), and when the number of priority group information is plural (≠ 1), the priority order is considered, the priority group information is merged, and the new group is added. Information is created (step S5).

After the new group information is created in step S5, or if the number of priority group information is 1 in step S4, the process proceeds to step S6 and the field information in the screen information file 3 is changed to the field information file. Edit from the field information in 2 for each attribute.
Here, when the field information item in the screen information file 3 is set to NULL, it follows the control information of the corresponding item in the field information file 2, and when set to X'FF ',
Judge that there is no control of the corresponding item. Then, the screen forming unit 5 automatically controls the screen layout based on these group information and field information (step S
7)

Therefore, the most effective use method of this system is to use the field information in the screen information file 3,
It is considered that the text information, EDIT information, and other information items are all set to NULL. In this case, the screen creator need only consider what field (attribute) to add to the screen after registering the group information file 1 and the field information file 2 when creating the screen.
It is no longer necessary to be aware of the layout.

Next, a concrete example will be described. 7 to 10
Shows sample data of registration screen control information. Also,
11 and 12 are flowcharts in that case, and FIG. 13 is a screen explanatory diagram.

In this example, the screen forming section 5 displays the "5500" screen. First, when the screen forming unit 5 receives a request for displaying "5500" screen from the AP (step S1), the screen forming unit 5 first GETs "5500" screen information from the screen information file 3 (step S1).
2). From this information, it can be determined that priority group information = 1, priority group = financing business group (step S3),
GET loan group information from group information file 1
Yes (step S4). Further, for all the field information in the screen information file 3 of "5500", the corresponding field information from the field information file 2 is GET using the attribute of the field as a key (step S5).

Next, the screen information file 3 of "5500"
The field information of the actual "5500" screen is edited on the basis of the field information in the field and the information obtained from the field information file 2 (step S6). In the sample data, since the text information, the EDIT information, and other information are all NULL, all the information is replaced with the GET information from the field information file 2.

The screen forming section 5 automatically controls the screen layout based on these pieces of information (step S7). That is, first, the base screen is displayed on the display screen 8 (step S8). (X1: 5, y1: 10, x
2:50, y2: 40). The display screens of steps S8 to S11 in FIG. 12 correspond to the screens of to in FIG.

Next, the title which is fixed data (approval registration)
Are laid out (step S9). (X3: 10, y
3: 5). Next, layout the store number and customer number fields. Display start position (10, 10), horizontal number of fields (MAX: 1, fixed: 1), overall priority (store number:
1, customer number: 2) (step S1)
0). However, the priority is high (the priority No. is low)
The fields are laid out in order from the top of the base screen. At this point, the display is not performed and the control is internally performed.

Next, the variable attribute field is centered, and as a result of the centering, the left position of all the fields is aligned with the left position as a reference, and the right position is aligned with the right position as a reference. After performing the layout control in this manner, the screen is displayed (step S11).

As described above, in the above embodiment, the screen forming unit 5 extracts the information corresponding to the group information and the field information shown in the screen information file 3 from the group information file 1 and the field information file 2. Since the screen is formed based on these information, the screen creator does not need to determine the screen layout fixedly (row / column position, etc.) for each screen, and also specify the group. This makes it easy to unify layout images systematically. In addition, maintainability such as addition / change / deletion of screens is greatly improved.

Also, by specifying the control information of the control specification section to be NULL in the field information of the screen information file 3, the text information of the field or E
Since DIT information and the like are specified, for example, even when adding a field to a certain screen, the screen creator only needs to increase the number of fields on the screen (add the field information) to create a new screen layout or field shape. It is not necessary to consider the above, and the burden on the screen creator is greatly reduced. Furthermore, since the field information unique to the screen can be given by designating the control information of the control designation unit to an arbitrary numerical value, it is possible to flexibly deal with various screen changes and the like.

In the above embodiment, as an example of screen creation,
Although the approval request screen has been described, the present invention is not limited to this, and various screens can be created.

[0034]

As described above, according to the screen control device of the present invention, the screen information file is provided with the group information file, the field information file, and the screen information file. The group information and the information corresponding to the field information are extracted from the group information file and the field information file, and the display is performed based on these information. Therefore, work such as screen creation and addition / change / deletion is performed. Can be easily performed, and the burden on the screen creator in such work can be significantly reduced.
