BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a drawing device for creating an initial screen, 2 is an input device such as a mouse, 3 is a drawing result display device such as a display device, and 4 is a drawing device 1
A storage device for storing the graphic data generated in step 5 is a graphic processing device that operates under program control, reads graphic data and changes graphic data, 6 is an application program that creates a screen that operates under program control, and 7 is A screen display device such as a display device or a printing device,
The storage device 4 is provided with graphic data 41, and this graphic data 41 stores graphic identification information and attribute information. Further, the drawing device 1 includes a screen editing unit 11 and a screen saving unit 12, and the screen editing unit 11 among them has a function of displaying on the drawing result display device 3 based on the input information provided by the input device 2. While checking the screen, perform graphic editing operations such as graphic layout and attribute changes. Further, the screen storage unit 12 manages the information of the graphic edited by the screen editing unit 11 and saves it in the graphic data 41.

Further, the graphic processing device 5 includes an initial screen generation unit 51, a graphic information management unit 52, and a graphic operation unit 53.
Of these, the graphic information management unit 52 manages the identification information and the attribute information of the graphic to be displayed, and performs a process of displaying on the screen display device 7 from these information. Further, the initial screen generation unit 51 reads the graphic data 41, registers the graphic identification information and the attribute information in the graphic information management unit 52,
The graphic operation unit 53 searches for specific graphic information among the graphic information managed by the graphic information management unit 52, and changes the graphic display attribute. Furthermore, application program 6
Is a process for displaying a target screen, and issues a request to the initial screen generation unit 51, the graphic information management unit 52, and the graphic operation unit 53.

Next, the operation will be described in detail with reference to FIGS. 2 to 9. First, in the screen generation device of the present invention, as shown in the flowchart of FIG.
To create a screen (step S1 in FIG. 2) and execute the application program 6 to create a screen (step S1).
2). That is, in the step S1, the screen editing unit 11
Then, based on the data input by the input device 2, the screen to be displayed is edited according to the application program.
Here, there are four types of input commands from the input device 2 in the screen editing unit 11: graphic generation, graphic identifier setting, graphic display attribute setting, and editing end.

FIG. 3 is a flow chart showing a screen editing processing procedure by the screen editing unit 11. Here, first, the input device 2 is waiting for input (step A
1) When an input is made, it is judged whether the input command is a figure generation command (step A2). If it is a figure generation command, figure generation processing is performed (step A6). In this figure generation process, the generated data is stored in the screen storage unit 12 and displayed on the drawing result display device 3. Then, after the figure generation process is completed, the process returns to the input waiting. If it is determined in step A2 that it is not the graphic generation processing, it is determined whether the input command is a graphic identifier setting command (step A3). If it is a graphic identifier setting command, graphic identifier setting processing is performed (step A7). In this graphic identifier setting process, the identifier data is stored in the screen storage unit 12 and displayed on the drawing result display device 3. However, if the identifier to be set already exists in the screen, the identifier data is not saved. After the graphic identifier setting process is completed, the process returns to the input wait.

Next, if it is determined in step A3 that it is not a graphic identifier setting command, it is determined whether the input command is a graphic display attribute setting command (step A4). If it is a graphic display attribute setting command, graphic display attribute setting processing is performed (step A8). In the graphic display attribute setting process, the type of display attribute and its setting value are stored in the screen storage unit 12 and displayed on the drawing result display device 3. After the graphic display attribute setting process is completed, the process returns to the input waiting. Finally, it is determined whether the input command is the edit end command (step A5). If it is a termination command,
The process of the screen editing unit 11 ends. After this editing is completed, the screen saving unit 12 saves the saved graphic information in the storage device 4 as graphic data 41.

If the input command does not correspond to any of the above commands, the process returns to the input wait. As a result, each process of graphic generation, graphic identifier setting, and graphic display attribute setting is performed many times until the end of editing. Figure generation,
The result of the command is displayed on the drawing result display device 3 regardless of the command for setting the graphic identifier and setting the graphic display attribute. Here, the data saved as the graphic data 41 is
It is the identifier of each generated graphic and the display attribute of the graphic. If there are multiple figures, they are listed. For example, as shown in FIG. 4, the screen editing unit 11 creates two straight lines,
When three rectangles are generated and identifiers are set respectively for the X axis, Y axis, bar 1, bar 2, and bar 3 and they are arranged at appropriate places, the graphic data 41 becomes as shown in FIG. .

Further, in the screen generation by executing the application program in step S2 of FIG. 2, as shown in detail in the flowchart of FIG. 6, when the application program 6 is executed, the initial screen generation unit 51 of the graphic processing apparatus 5 is executed. In, the graphic data 41 is read to generate an initial screen (step B1), then the graphic information to be changed is set (step B2), and finally displayed on the screen display device 7 (step B3). Here, in the process of step B1, the graphic data 41 stored in the screen storage unit 12 is read from the storage device 4 and registered in the graphic information management unit 52. The graphic information to be registered is graphic identifier information and graphic display attribute information. For example, the graphic data in FIG. 5 is in the same state in the graphic information management unit 52 at this point.

Next, in the process of step B2, the application program 6 issues a change request to the figure operation section 53 to change the information in the figure information management section 52. This will be described with reference to FIG. 7. The graphic operation unit 53 is passed from the application program 6 the identifier of the graphic whose setting is to be changed, the type of display attribute and the actual set value (step C1). At this time, first, the graphic operation unit 53 determines whether or not the graphic information management unit 52 has the identifier of the graphic to be changed (step C2). This is determined by comparing the identifier of the graphic to be changed with the identifier of the graphic managed by the graphic information management unit 52 and determining whether they match. If the graphic information management unit 52 does not have the graphic, the graphic does not exist.
Exit without doing anything.

On the other hand, when the figure to be changed exists, the figure operation unit 53 determines whether or not the figure has the display attribute to be changed (step C3). This is determined by comparing the type of the display attribute of the graphic to be changed with the type of the display attribute stored in the graphic information management unit 52 to see if they match.
If the display attribute to be set exists, the graphic operation unit 53 replaces the already saved information with the designated setting value and changes the setting value (step C4). If the display attribute to be set does not exist, the graphic operation unit 53
The type of information and the set value are newly stored in the graphic information management unit 52 (step C5). By this, one display attribute of one figure can be set. However, in the case of setting many display attributes, the application program 6 repeats this work many times.

Concretely, it is considered that when the graphic data of FIG. 5 is read into the graphic information management unit 52, the size of the bar 1 and the color of filling are changed. In FIG. 8, the graphic identifier is bar 1, the attribute type is size, and the display attribute setting value is (3
0,200) (step C1). The graphic operation unit 53 includes, in the data of the graphic information management unit 52,
It is searched whether there is an identifier of bar 1 (step C2). In this example, the search succeeds because there is a graphic with an identifier of bar 1 at the third position. Next, the graphic operation unit 53
The data of the bar 1 is searched for whether or not there is a display attribute of size (step C3). In this example, since the display attribute of the third size is present, the search is successful. Finally, the figure operation unit 53 changes the size from (30,160) to (30,200) (step C4).

In FIG. 9, it is assumed that the graphic identifier is bar 1, the attribute type is a fill color, and the display attribute setting value is (red) (step C1). As in the previous example, since there is a graphic with an identifier of bar 1, the search is successful (step C2). Next, the figure operation unit 53 searches the data of the bar 1 for a display attribute of a fill color (step C3). In this example, the search fails because there is no display attribute called fill color. for that reason,
The figure operation unit 53 adds an attribute called fill color,
A set value (red) is set (step C5). Finally, as shown in step B3 of FIG. 6, the application program 6 issues a drawing request to the graphic information management unit 52, and the graphic information management unit 52 uses the managed graphic information to display the screen display device 7. Output to.

Next, another embodiment of the present invention will be described with reference to FIG.
Will be described. This is one of the configurations shown in FIG.
Drawing device 1, graphic data 41 and initial screen generation unit 51
Are replaced with other drawing devices 1X, graphic data 41X, and initial screen generation unit 51X. here,
The drawing device 1X is a drawing device different from the drawing device 1, and the data to be saved is also in the form of graphic data 41X different from the graphic data 41. Initial screen generation unit 51X
Analyzes the data of the graphic data 41X and sets the graphic display attribute to the graphic information management unit 52.

In this embodiment, for example, the drawing device 1
It is assumed that X generates screen data without a graphic identifier, as shown in FIG. At this time, the initial screen generation unit 51X adds a graphic identifier so that the application program 6 can change the graphic display attribute.
You must register to. Referring to FIG. 12, in the initial screen generation unit 51X, first, one figure is read from the figure data 41X (step D1), and the data has some regularity, for example, "first" or the like. An identifier is added (step D2), and the screen information management unit 5
2 is registered (step D3). Thereafter, it is judged whether or not there is the next graphic data (step D4), and if there is, the graphic reading is repeated again.

As a result, the application program 6 can change the display attribute of this figure with the identifier "first", and as a result, the screen created by the drawing device can be used regardless of the type of the drawing device. Can be changed by the application program. The reason is that the graphic data is interpreted and processed so that it can be used by the application program when the initial screen is generated.

FIG. 13 shows still another embodiment of the present invention. This is a configuration in which a graphic addition unit 54 is added to the configuration shown in FIG. The graphic addition unit 54 has a function of newly generating and registering a graphic in the graphic information management unit 52. According to this, in step B2 of FIG. 6, the application program 6 not only changes the existing graphic information but also requests the graphic adding unit 54 to add a graphic. Therefore, referring to FIG. 14, the graphic addition unit 54
The graphic program identifier and graphic type are passed from the application program 6 (step E1). Next, it is judged whether or not the figure exists with the already specified identifier (step E2 in FIG. 14). If the figure already exists, it cannot be added, and the process ends. On the other hand, if it does not exist, a graphic of the designated type is added (step E3), and the process is terminated.

A concrete example of this is shown in FIG. In this FIG. 15, two figures are being added. One is the graphic identifier "bar 1", the graphic type is "rectangle", and the other is the graphic identifier "bar 4" and the graphic type is "rectangle". Here, in the case of the stick 1, since the stick 1 already exists, the addition fails at step E2. On the other hand, in the case of the stick 4, since the stick 4 does not exist, the data “stick 4, type (rectangle)” is added. As a result, the application program 6 can newly add a graphic.

[0027]

As described above, according to the present invention, the drawing apparatus does not generate the source program which is a part of the application program, but generates the graphic data independent of the application program. Since the screen is generated by reading the graphic data, it is possible to create an application program without depending on the drawing device. In other words, in the case of Visual Basic, there is no limitation such as creating a screen with the drawing device attached to it. With any application program, it is possible to obtain the effect of being able to generate a screen with a drawing device that is familiar. Also, by clearly separating the application program and the graphic data, only the graphic data can be used by other application programs, and as a result, the screen created by the plotter can be reused by other application programs. The effect of becoming is obtained.

Further, when the modification of the screen requires only the modification of the graphic data, it is sufficient to modify the graphic data with the drawing device, so that the screen can be modified without changing the application program, Since the graphic data on the screen is not a program, the size of the application program is small, and especially when the same graphic data is used by a plurality of application programs, this effect is large.
