FIG. 2 is a block diagram illustrating an example of a hardware configuration of the program generation device and the information processing device according to the present invention.

The information processing apparatus is a computer on which a program generated by the program generation apparatus operates, and may be the same computer as the program generation apparatus or a different computer.
The same components as those in FIG. 1 are denoted by the same reference numerals. As shown in FIG. 2, the program generation device shown in FIG. 1 can be realized by a personal computer or the like.

  The CPU 201 is configured to comprehensively control access to various devices connected to the system bus based on a control program stored in the ROM 203 or the external storage device 104.

  The system bus is connected to a RAM 202 that functions as a main memory, work area, and the like for the CPU 201. The ROM 203 or the external storage device 104 implements a process executed by a BIOS (Basic Input / Output System), an operating system (hereinafter referred to as “OS”) program, and a program generation device (computer) 103, which are control programs of the CPU 101. Various programs necessary for this are described.

  The CPU 201 implements the functions and various functions of the overall control unit 108 shown in FIG. 1 by loading various programs necessary for execution of processing into the RAM 202 and executing the programs.

  The external storage device 104 can store a boot program (not shown), various application programs, font data, user files, and the like as the various programs described above.

Further, the CPU 201 opens various registered windows based on commands instructed by a mouse cursor (not shown) on the display device 102 and executes various data processing.

  FIG. 3 is a diagram showing an example of the overall configuration of an application system using the code generated by the code generation unit 107 of the program generation apparatus according to the present invention.

  A client 301 and a server 304 are communicably connected via a network. In response to a request from the client 301, screen display information is transmitted to the client 301 from the server 304 on which the program generated by the program generation apparatus 103 operates.

  Specifically, the servlet, JSP, and Bean generated by the code generation unit 107 are arranged on the application server 306 on the server 304 side in an executable state.

  This web application system is used from the client 301 by the web browser 302. By accessing the JSP 309 from the Web browser 302, an HTML page 303 is generated and transmitted to the client 301 side. Then, an HTML page 303 transmitted from the JSP 309 is displayed on the Web browser 302.

  A request from the Web browser 302 is transmitted to the server 304 side via HTTP. The server 304 includes an HTTP server 305 and an application server 306, and the application server 306 includes an execution environment for the servlet 307 and the JSP 309.

  When a request is transmitted to the server 304 side, the corresponding servlet 307 is activated according to the request. The servlet 307 requests the corresponding Bean 308 to perform processing. Further, the Bean 308 accesses the DB access object 310a, the internal database 311a, and the external database 311b in response to a request from the servlet 307, and holds the processing result in the Bean 308.

  Next, the Bean 308 is passed from the servlet 307 to the JSP 309 and the JSP 309 is called. The JSP 309 refers to the processing result held by the Bean 308, generates an HTML page, and returns it to the client 301 side. The HTML page returned to the client 301 is displayed on the Web browser 302.

  The servlet 307 has a role of controlling the connection between the reception of a request from the Web browser 302, the processing request to the Bean 308, and the call to the JSP 309. The JSP 309 is responsible for processing related to display for outputting an HTML page, and the Bean 308 is responsible for processing related to operations such as access to the databases 311a and 311b.

Although it is possible to process a request from the Web browser 302 using only the servlet 307 without using the Bean 308 or JSP 309 (or using only the JSP 309 without using the servlet 307 or Bean 308), the Bean 308 or JSP 309 can be processed. By clearly separating each role using the function, it is possible to grasp the functional division in a concise manner.
Note that the Bean 308 may be separately implemented as a Bean for internal database access and a Bean for external database access.

The file attachment screen 700 displays attachment 701, attachment 1 (703), and attachment 2 (706) as item names. A text area 702 and a file area 704 are displayed as corresponding input areas.
In addition, a registration button 707 and a cancel button 708 are displayed as buttons.

This screen is a screen program generated by the program generation device using the item definition information shown in FIG. The relationship with the item definition information will be described with reference to FIG.
FIG. 12 is a diagram showing an example of item definition information in the present invention.

  As the item definition information 1200, IOCODE 1201, CODE 1202, NAME 1203, ORDER 1204, SIZE 1205, TYPE 1206, and VALUE 1207 are defined.

IOCODE 1201 is a value for identifying a screen, and one code is assigned to one screen. In this embodiment, IOCODE of the file attachment screen 700 is defined as IO01.
CODE 1202 is a value for identifying an item, and the item on the screen is uniquely determined by IOCODE 1201 and CODE 1202.

  NAME 1203 is the name of the item and the name displayed on the screen. ORDER 1204 is the order of items, and is used when expanding items. The items are arranged on the screen according to this order.

  SIZE 1205 is an upper limit value of the size for the item, and the unit in the embodiment is expressed in bytes. The upper limit of text input for remarks is 1500 bytes, and the upper limit size of a file input to the file area is defined as 100,000 bytes.

  Value 1207 is a detailed definition for an item. When it is defined as Textarea, text can be input, and when it is D & D, the item is an item that can be dragged and dropped.

  Drag and drop (DnD) is one of operation methods using a mouse or touch operation, and is to move data or files by a cursor operation or the like.

  In the present embodiment, drag and drop can be performed on an item for which Value 1207 is defined as D & D. For example, the user moves (drags) the mouse with the file selected on the screen, and releases the mouse button (drop) with the mouse pointer over the file area 704 to input the file into the file area 704. Is possible.

An open screen 710 is a screen for selecting a file by a file picker. A folder can be selected in the folder display area 711 and a file 713 displayed in the file display area 712 can be selected.
The selected file 713 is input and displayed in the file area 721 of the file attachment screen 720.
FIG. 8 is a diagram showing an example of the first item expansion screen in the present invention.

  By dropping the file 803 with respect to the attachment 1 (802) by a drag-and-drop operation, the file area 804 is expanded and displayed together with the message “Please drop”. A file area 804 is a reception area that can accept file selection, and display control is performed by the reception area setting means.

The message “Please drop” may be displayed when a moving state such as the position of the mouse cursor is detected and the file area 804 is at a position where it can be dropped.
An operation that can be set by a drag and drop operation of a file will be described with reference to FIG.
FIG. 11 is a diagram showing an example of a display setting screen for setting display of items in the present invention.

  The developer management screen 1100 is an item that can be set on the developer management screen, and is a screen that can define detailed operations when dragged and dropped. A program is generated according to the items set on this screen.

  In the item setting 1101, the CODE 1202 item of the item definition information 1200 is set. Since the item name 1102 indicates “Attachment 1”, the setting is for file1. The item setting can be arbitrarily added. In the embodiment, in addition to the attachment 1, in the item setting 1110, detailed setting is made for the attachment 2 as the item name 1112.

  When the area expansion 1103 is checked, when it is detected that the file has been dragged and dropped and an item that can accept the file is approached, the reception area expansion means displays the item (reception area corresponding to the item) in an expanded manner and accepts the drop. The possible area can be expanded.

  If the direction option 1106 is checked, the item is expanded and displayed depending on which direction (for example, upward direction) the file drag-and-drop is approaching from the item that can accept the file. Is done.

When the interval adjustment 1104 is checked, control is performed to shift the display position of the items arranged above and below using the ORDER 1204 so that the expanded displayed item does not hide the other displayed items. At this time, the display position may be adjusted only when an item whose Value 1207 is D & D is hidden.
When the save button 1120 is pressed, it is stored in the business specification description section 106 or the like.
Returning to the description of FIG.
The file attachment screen 800 is a screen showing an example when a file is dragged and dropped from above.
Since the file 803 is dragged and dropped from above, the file area 804 is expanded and displayed upward.
Further, since the remark 801 is not an item defined as D & D, the display position is not changed upward even when the file area 804 is expanded and displayed.

The file attachment screen 720 is a screen when the file is dragged and dropped from above and the file area 813 corresponding to attachment 2 (815) is expanded and displayed.
The file area 813 is expanded upward, and the item above the item corresponding to Attachment 1 (811) is displayed shifted upward.
FIG. 9 is a diagram showing an example of the second item expansion screen in the present invention.
File attachment screens 900 and 910 show examples in which file drag and drop is performed from below.

  In the file attachment screen 900, the file area 812 corresponding to attachment 2 (813) is expanded and displayed downward, and the registration button 815 is not a D & D item, and thus the display is not shifted downward.

The file attachment screen 910 shows a state in which the file 912 is dragged and dropped on the attachment 1 (911) and the file area 913 is expanded and displayed downward.
At this time, since Attachment 2 (914) is a D & D item, it is displayed in a downward direction.
FIG. 10 is a diagram showing an example of a screen displaying the result of the size check in the present invention.
FIG. 12 is a screen image when a file drop is accepted when the size check 1105 in FIG. 11 is checked.

  If the file size does not exceed the limit, the file name accepted as “Attachment 01.pdf” 1001 is displayed in Attachment 2 as shown in the file attachment screen 1000.

On the other hand, when the file size exceeds the upper limit, a message such as “The file size exceeds the upper limit” is output to the file area 1011 as shown in the file attachment screen 1010. Further, when determining the file type described in FIG. 15, the file types that are not permitted are registered in the file area 1021 as shown in the file attachment screen 1020, in the file area 1021, files other than jpg, png and gif are registered. The message "Cannot be done" is output.
FIG. 13 is a flowchart showing an example of a control processing procedure of code generation processing of the program generation device according to the present invention.

  Steps S1301 to S1302 are processes operated by the developer, and steps S1303 to S1310 are processes performed by the program generation device. The developer may perform an operation from an administrator terminal, or may perform an operation by directly accessing the program generation device.

  In step S1301, an input of a definition related to a screen program at the time of drag and drop of a screen item is received from the developer, and in step S1302, a press of a program generation processing button on the development management screen is received.

In step S1303, when a program generation request is received from the development management screen, the process advances to step S1304 to read the item setting information set on the development management screen from the input / output table, and whether or not the contents input in step S1305 are incomplete. Check for errors.
If there is an error in step S1306, the error is displayed on the development management screen in step S1307, and the process ends.

If there is no error, the process advances to step S1308 to generate a screen control program that accepts file input by the drag-and-drop operation described with reference to FIGS.
In step S1309, a size check program is generated corresponding to the size check 1105 in FIG.
In step S1310, a screen program including the program generated in steps S1303 to S1309 is generated, and the process ends.

The operation of the screen control program generated in step S1308 will be described using FIG. 14, and the operation of the size check program generated in step S1309 will be described using FIG.
FIG. 14 is a flowchart illustrating an example of a screen control process of the information processing apparatus according to the present invention.
This process is not the process itself performed by the program generation apparatus of the present invention, but a process when a program generated by the program generation apparatus is executed.

  In step S1401, the browser receives an event where dragging has started. In step S1402, the Y coordinate (y1) of the mouse position is received from the event during drag and drop of the file. In step S1403, the Y coordinate (y2) of the mouse position after a lapse of a fixed time from step S1402 is received.

In general, the uppermost Y coordinate in the browser is 0, and the numerical value increases as it goes down. Therefore, by comparing the Y coordinate (y1) acquired in step S1402 and the Y coordinate (y2) acquired in step S1403, it is possible to determine in which direction the drug is being dragged.
In step S1404, it is determined whether y1> y2, that is, whether dragging from top to bottom or dragging from bottom to top. This step makes it possible to detect the direction of movement relative to the reception area.

If y1> y2 is not satisfied, NO is determined to be dragging from the top to the bottom, and the process proceeds to step S1405. If y1> y2, YES is determined to be dragging from bottom to top, and the process proceeds to step S1406.
In step S1405, the extension area of the file area is determined upward, and in step S1406, the extension direction of the file area is determined downward.

  In step S1407, it is determined whether the cursor being dragged is staying in an area (file acceptable item) where the cursor can be dropped. If not, the process ends.

  On the other hand, if the user is staying, the process advances to step S1409 to determine (specify) whether the item in the extending direction is an item that can be dropped (item specifying means). The item in the extending direction is determined by the setting of ORDER 1204 in FIG. For example, if the ORDER is 20 in the attachment 1, the upper item is a remark that the ORDER is 10, and the lower item is an attachment 2 in which the ORDER is 30.

  Whether or not the item can be dropped can be identified by whether or not the item of Value 1207 is D & D (item that can be dropped if it is defined as D & D). Thereby, the droppable item is not hidden even if other items are expanded, and can be displayed in a droppable state.

  If the item in the extending direction is not a droppable item, the item is expanded in a state of covering the item in step S1410. If the item is droppable, the item is pushed out (shifted) and displayed in step S1411. .

In step S1412, when the event that the mouse leaves the droppable area is received, the droppable area expanded in step S1413 is returned to the original, and the process ends.
Note that the processing of this flowchart does not necessarily require that all steps be processed according to the details of the detailed settings set in FIG.
FIG. 15 is a flowchart showing an example of file acceptance processing of the information processing apparatus according to the present invention.
Processing is started when a file is dropped in the file area on the screen of FIG. 8 or FIG. 9. In step S1501, the browser receives an event that a file is dropped in the droppable area.
In step S1502, it is determined whether the size of the dropped file exceeds the upper limit. It functions as a file size determination means.

  Whether or not the upper limit is exceeded is determined when the size check 1105 in FIG. 11 is selected, and the upper limit of the file size uses the size defined in the SIZE 1205 in FIG.

If the file size exceeds the defined value, the process proceeds to step S1503, and the file size exceeds the upper limit in the file attachment screen 1010 in FIG. ) Is displayed.
Note that this processing is controlled by the drop operation control means, but “impossible to drop” includes that which restricts not to accept the drop and that which displays that the drop cannot be performed.

  On the other hand, if the file size does not exceed the defined value (contains), the file is uploaded to the server in step S1504, and the display of the file item is changed as shown in the file attachment screen 1000 of FIG. 10 in step S1505. To finish the process.

FIG. 16 is a flowchart showing an example of the second file acceptance process of the information processing apparatus according to the present invention.
In FIG. 15, the process of determining whether the size of the dropped file exceeds the upper limit has been described. However, in FIG. 16, it is determined whether the type of the dropped file is a permitted file type. The process will be described as a second file acceptance process.

As in FIG. 15, the process is started when a file is dropped on the file area on the screen of FIG. 8 or FIG.
In step S1601, the browser receives an event that a file is dropped in the droppable area.

In step S1602, it is confirmed whether the dropped file is a permitted type file. Processing is performed by the file type determination unit determining the file type acquired by the file type acquisition unit.
Specifically, the attachment of the permitted type of file is permitted and the process proceeds to step S1604, and the unacceptable type of file proceeds to step S1603, and the unpermitted file type as shown in the file area 1021 of FIG. Notify that.

  It is only necessary to register permitted file types and unpermitted file types from a registration screen (not shown). For example, if it is registered that a file whose file extension is “jpg, ping, gif” is registered as a type of file that is permitted to be registered, a file that is not permitted (for example, a file in the bmp format) is obtained. If the file is dropped, a warning “File other than jpg, png, and gif cannot be registered” is displayed as indicated by reference numeral 1021 in FIG.

  The warning (error) message is not limited to this, and the file selection may not be accepted without issuing a warning message.

  If the file is an allowed file type, the file is uploaded to the server in step S1604, the display of the file item is changed as in the file attachment screen 1000 of FIG. 10 in step S1605, and the process ends.

  FIG. 17 is a flowchart showing an example of item expansion processing of the information processing apparatus according to the present invention.

FIG. 11 is a detailed flow of processing for expanding and displaying a droppable area shown in FIG. 10. FIG.
In step S1701, it is determined whether to display the next item with a droppable area. Specifically, the determination is the same as the determination in step S1409 in FIG. 14, and the case where the process proceeds to step S1410 is displayed over the next item (YES), and the case where the process proceeds to step S1411 is No item is displayed over the item (NO) (the next item is pushed and expanded).

  If it is determined that the next item is not displayed, the process advances to step S1702 to set “height” in the droppable area. As a result, as shown in the droppable area 813 in FIG. 8 and the droppable area 912 in FIG. 9, the next item is displayed above and below, so that it is not displayed.

  On the other hand, if it is determined that the next item is to be displayed, the process advances to step S1703 to set “z-index” and “height” in the droppable area. As a result, a dropable area 804 in FIG. 8 and a dropable area 812 in FIG. 9 are displayed so as to overlap (over) the next item.

  “Height” is an item for setting the height of the droppable area, and is set in units of px, for example. By default, 0 is set. For example, by setting “height: 25 px”, the height is displayed as 25 px. px is a unit in which one pixel is 1, and the actually displayed size varies depending on the resolution of the monitor such as 72 dpi or 96 dpi.

“Z-index” is an item for setting whether or not to display the drop area in an overlapping manner. When a value is set, it is displayed in an overlapping manner. Usually, it is 1, and for example, by setting z-index = 10, the images are displayed in an overlapping manner.
In step S1704, when an event that the mouse has moved away from the droppable area is received, in step S1705, the height of the expanded droppable area is set to 0 to return the droppable area to the original, and the process ends.

  FIG. 18 is a flowchart illustrating an example of the second screen control process of the information processing apparatus according to the present invention.

Since the process of step S1801 is added to the process of FIG. 14, the description of steps S1401 to S1413 is omitted.
If it is determined in step S1408 that the user has stayed in the droppable area for a predetermined time or more, whether the file dropped in step S1801 is a permitted file and / or a permitted size. Judgment is made. If it is not permitted, the process ends. If it is permitted, the process proceeds to step S1409.

  Whether or not the file is permitted is determined by acquiring the file information being dragged from the operating system or by acquiring the file information acquisition module or application.

  When file information being dragged cannot be acquired, selection permission / non-permission is determined by acquiring the file size and file type when the file is dropped, as shown in FIGS. do it.
