Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an object-oriented screen display control method for converting a function and a graphic constituting a screen into objects and displaying a screen by combining objects.

[0002]

2. Description of the Related Art As a conventional technique, for example, Japanese Unexamined Patent Publication No.
An object-oriented screen display control method disclosed in JP-A-335166 will be described. FIG.
FIG. 166 is a functional block diagram showing a conventional object-oriented screen display control method disclosed in Japanese Patent Publication No. 166. In FIG. 17, reference numeral 4 denotes a screen to be displayed, and 5 denotes a screen object supply unit having each object obtained by converting each function of the screen 4 into a function.
A code conversion object 53, an input edit object 54, an event input object 55, a display edit object 56, a key input object 57,
It has a function key input object 58 and a screen output object 59. Reference numeral 6 denotes an object manager that controls objects on the screen 4 and corresponds to a screen display control program. Reference numeral 7 denotes a graphic drawing program for drawing a graphic, 100 denotes a screen definition format that defines each function of the screen and a ruled line pattern on the screen, and the screen operates in a window system (multi-window) environment having a plurality of work areas. Shall be.

In the conventional object-oriented screen display control method, when a screen display request occurs, the object manager 6 refers to the screen definition format 100,
Objects corresponding to each screen function defined in the screen definition format 100 are sequentially called from the screen object supply unit, and processing of each object is performed, thereby realizing screen display. After the screen display is completed, the system waits for the next request (screen display, key input, PF key input, etc.), and when a key input request occurs, calls a key input object 57 for performing processing related to key input and performs processing. I do.

Next, the operation of the conventional object-oriented screen display control method will be described with reference to the processing flow of FIG. First, at the stage of a1, when the object manager 6 is started, the object manager 6
Creates a window at the stage a2, and waits until an event interrupt occurs at the stage a4. At this time, the display data is read in the stage a3 with reference to the screen definition format 100. Here, it is assumed that a display mode of “display integer data with commas” is defined in the screen definition format 100. At the stage a3, when the data reading is completed, an event interrupt of the data reading completion is generated for the stage a4. Therefore, the processing of the stage a6 is executed according to the analysis result of the event a5.

[0005] Stage a6 is a screen definition format 1
In accordance with the data display specification defined in 00, necessary objects (display edit object 56, screen output object 59) are linked and edited (dynamic link) at runtime. Here, when the read integer data is “1523” in the stage a3, the comma “,” is edited and converted to a character type in the stage a61 to obtain the character “1,523”. In the stage a62, a character string with a comma is displayed at the coordinates of the window. When the screen display is completed, return to stage a4,
It is again in a state of waiting for an interrupt.

That is, the object manager 6 generates the screen definition format 10 according to the generated event information (screen display, input, etc.) and each screen definition format 100.
Objects are executed according to the processing order described in “0”. In this method, the corresponding object is executed according to the display pattern defined in the screen definition format 100. Therefore, even if the display mode is changed from “with commas” to “real number type”, The syntax is changed from "with comma" to "real type"
, The object manager 6 can automatically call the corresponding object and control the screen display. Also, when displaying a type that is not in the existing display mode, it is possible to cope with it only by adding “new display edit” as a syntax. However, the graphic drawing program 7 draws a graphic on the screen before the display processing of the functional object.

[0007]

Since the conventional object-oriented screen display control system is configured as described above, there is a problem that graphics must be corrected for each screen, and the number of screens is several hundred. Even in a large-scale system with more than one hundred and hundreds of thousands of parts per screen, there is a problem that all types of objects must be prepared, and a screen definition format is created for each screen. The problem that the number of screen definition formats is large, the problem that the syntax of the screen definition format becomes long and it takes time to create and maintain, and the overhead that is required each time the object manager calls a part increases, deteriorating the performance. There was a problem.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has several hundreds or more screens.
The objective is to obtain an object-oriented screen display control method that can efficiently create and maintain screen definition formats and objects even in large-scale systems with hundreds of thousands of parts per screen. .

FIG. 2 is a diagram showing the operation of the object-oriented screen display control system according to the first embodiment of the present invention. Next, the operation of the object-oriented screen display control method according to the first embodiment will be described using the processing flow of FIG. First, when the object manager 61 is activated at the stage a1, the object manager 61 creates a window at the stage a2,
In this stage, the process waits until an event interrupt occurs. At this time, the display data is read in the stage a3 with reference to the screen definition format 110. Here, the screen definition format 110
In this example, a figure “rectangle” indicating a display frame and a display form “display integer data with commas” are defined. At the stage a3, when the data reading is completed, an event interrupt of the data reading completion is generated for the stage a4, so that the process of a6 is executed according to the analysis result of the event of a5.

In the stage a6, the required rectangular object 92, display edit object 56, and screen output object 59 are connected and edited at run time in accordance with the data display specification defined in the screen definition format 110. At the end of the screen display, the process returns to the stage a4, and is again in a state of waiting for an interrupt.

At this time, the display data is read in the stage a3 with reference to the screen definition format 120. Here, in the screen definition format 120, an object "character string display" which is a composite of a graphic "rectangle" indicating a display frame and a display mode "display integer data with commas" is defined. And At the stage a3, when the data reading is completed, an event interrupt of the data reading completion is generated for the stage a4. Therefore, the processing of a6 described below is executed according to the analysis result of the event of a5.

In the stage a6, necessary objects (character string display object 101, screen output object 59) are linked and edited at runtime according to the defined data display specification in the screen definition format 120. When the screen display is completed, return to stage a4,
It is again in a state of waiting for an interrupt. That is, the object manager 62 executes objects in accordance with the processing information described in the screen definition format 120 in accordance with the generated event information (screen display, input, etc.) and the screen definition format.

As described above, according to the second embodiment, the screen definition format and the object manager can handle complex objects. Therefore, by defining a complex object in the screen definition format, Since the number of lines of the syntax can be reduced, the screen definition format can be created and maintained efficiently. Further, even if a new object is added to the composite object, only the definition of the composite object is changed, so that there is no need to change the screen specification for calling the composite object.
