However,
In a device that does not have software for displaying a figure, the display information cannot be processed, and an error occurs and nothing is displayed. In other words, even if there is software for displaying a document, if there is no software for displaying a figure, not only a figure but even a document is not displayed. In order to solve such a situation, there has been no other way but to install (set) software for displaying graphics in the apparatus.

[Problems to be Solved by the Invention] As described above, in a conventional electronic document editing apparatus, when a plurality of types of software are required to process given display information, even if one piece of software is missing, Since the content indicated by the display information is not displayed at all, there is a problem that even a part of the content cannot be grasped.

Therefore, the present invention processes a displayable portion of the display information and displays the content even if a part of the software is missing. It is an object of the present invention to provide a display method in an electronic document editing device for displaying a document.

Means for Solving the Problems According to the present invention, in an electronic document editing apparatus which processes display information based on a plurality of functions and displays contents corresponding to the display information, the display information is divided into partial display information. Then, the partial display information and each function name indicating a function for processing the respective partial display information are given to a plurality of objects, respectively, and when the object is processed, a function name of the object The function is searched by the search means, and if the function of the function name is not searched, the fact that the search was not performed is displayed on the display means, and if the function of the function name is searched, the function based on the function is used. The partial display information of the object is processed by the editing means.

[Operation] According to the present invention, display information is processed for each of a plurality of objects, and when a function having a function name of the object is not searched, it is displayed that no search was performed,
When the function having the function name is searched, the partial display information of the object is processed based on the function, and the content corresponding to the partial display information is displayed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 show an embodiment of a display system in an electronic document editing apparatus according to the present invention.

FIG. 1 shows a configuration of a text object including display information processed in this embodiment. This text object 1 is composed of a plurality of partial objects 1-1 to 1-1.
1-n. These partial objects 1
Each of -1 to 1-n is given partial display information obtained by dividing the display information, and is given a display function name and a handler name indicating a function (software) for processing the partial display information. . The handler name indicates a data input / output function for a partial object having the handler name, an editing function for editing data, and the like, and the display function name is a display function expanded based on the function of the handler name. It shows.

If the function of the display function name and the function of the handler name given to the partial object are set in the electronic document editing apparatus in advance, the partial display information is processed based on these functions, The contents are then displayed.

FIG. 2 is a functional block diagram in the present embodiment. In FIG. 1, an object extracting unit 21 sequentially selects and extracts each of the partial objects 1-1 to 1-n of the text object 1 provided to the electronic document editing apparatus. The handler function search unit 22 is an object extraction unit
The electronic document editing apparatus searches for each function of the handler name and the display function name of the partial object extracted by 21. The handler function extracting unit 23 extracts each function searched by the handler function searching unit 22. The object editing unit 24 performs editing based on the partial display information of each function and the partial object extracted by the handler function extracting unit 23, and the editing result, that is, the display content corresponding to the partial display information is stored in the object storage unit 25. Is stored in The object display unit 26 displays the display contents stored in the object storage unit 25. The dummy display unit 27 displays a predetermined dummy elephant in place of the display content corresponding to the partial display information when each function cannot be found by the search by the handler function search unit 22.

The object display section 26 and the dummy display section 27
Actually, each display is appropriately displayed on the screen of one display device (for example, a CRT).

Next, a more specific processing example of a text object will be described.

First, it is assumed that the text object 1 includes three partial objects 1-1, 1-2, and 1-3.

In this case, the object extracting unit 21 sequentially extracts each of the partial objects 1-1, 1-2, and 1-3 from the text object 1 and sequentially supplies these partial objects to the handler function searching unit 22. The handler function search unit 22 searches each function of the display function name and the handler name of the partial object every time each partial object is given, and if there are these functions, the partial object is transferred to the handler function extracting unit 23. give.

When each of the partial objects 1-1, 1-2, and 1-3 is sequentially given to the handler function extracting unit 23 in this way, each time the handler function extracting unit 23 executes the respective functions of the display function name and the handler name of the partial object. And gives these functions to the object editing unit 24 together with the partial objects. When given the partial object and each function of the partial object, the object editing unit 24 performs editing based on the partial display information of the partial object and each function, and stores the display contents obtained thereby in the object storage unit 25. I do.

As a result, each display content corresponding to each partial display information of each of the partial objects 1-1, 1-2, and 1-3 is sequentially stored in the object storage unit 25. Each of the partial objects 1-1 and 1-1 stored in the object storage unit 25
The respective display contents corresponding to 1-2 and 1-3 are displayed on the display screen by the object display unit 26.

FIG. 3 shows the respective display contents displayed on the display screen. In the first line, a character string "start" corresponding to the partial display information of the partial object 1-1 is displayed. A straight line 61 which is a graphic corresponding to the partial display information of the partial object 1-2 is displayed on the eyes, and a character string "end" corresponding to the partial display information of the partial object 1-3 is displayed on the third line. ing.

FIG. 4 shows respective data to be developed when the respective partial display information of each of the partial objects 1-1, 1-2, and 1-3 is edited.

FIG. 4A shows data developed when editing the partial display information of the partial object 1-1.
Here, a character code indicating the character string “start” is arranged.

FIG. 4 (b) shows data developed when editing the partial display information of the partial object 1-2.
Here, data for deriving a straight line which is a figure is described.

FIG. 4 (c) shows data developed when editing the partial display information of the partial object 1-3.
Here, a character code indicating the character string “end” is arranged.

Here, looking at FIG. 4 (b) in more detail, the address “# 54,62256” necessary to derive a straight line which is a figure is written in the first line in the column of this data. The data accessed based on this address is as shown in FIG.

In the column of data in FIG. 5, the second line displays display data "(RULE, WIDTH 2
BOUNDBOX (386 2 0 0)) ”and the second line shows the function“ @IMAG with the handler name “# 56,12340”.
EFNS @ # 56,12340 ". This function" @IMA
The data accessed based on GEFNS @ # 56,12340 "is as shown in FIG.

In the data column of FIG. 6, the display function name "HRULE.DISPLAYFN" is entered on the first line, and a display function called "HRULE.DISPLAYFN" is accessed based on the display function name. Can be.

Using the display function of the display function name “HRULE.DISPLAYFN” thus obtained, the display data “(RULE, WIDTH 2 BOUND
BOX (386 200)) ”, the straight line 61 shown in FIG. 3 can be drawn.

Now, when editing the partial display information of the partial object 1-2, the handler name "# 56,1234" shown in FIG.
0 "and the display function name" HRULE.DISPLAY shown in FIG.
FN "is required, so that these handler names and display function names are given to the partial object 1-2 in advance.

Therefore, when given the partial object 1-2, the handler function search unit 22 receives the handler name "# 56,1
2340 "and the display function name" HRULE.DISPLAYFN "are searched, and after confirming that these functions are present, the partial object 1-2 is transferred to the handler function extracting unit.
Give to 23. Then, the handler function fetching unit 23 outputs the handler name “# 56,12340” and the display function name “HRULE.
DISPLAYFN ”, and fetches these functions together with the partial object 1-2.
Give to. Thereby, editing based on the partial display information of the partial object 1-2 and the respective functions of the handler name "# 56,12340" and the display function name "HRULE.DISPLAYFN" is performed, and the display obtained by this editing is performed. The content is stored in the object storage unit 25, and the straight line 61 shown in FIG. 3 is displayed on the display screen by the object display unit 26.

By the way, if the respective functions of the handler name “# 56,12340” and the display function name “HRULE.DISPLAYFN” are not set in the electronic document editing apparatus in advance,
When given the partial object 1-2, the handler function search unit 22 cannot find the respective functions of the handler name "# 56,12340" and the display function name "HRULE.DISPLAYFN".

In such a case, the handler function search unit 22 activates the dummy display unit 27. In response, the dummy display unit 27 displays a dummy elephant instead of a straight line, that is, a message “Unknown IMAGEOBJ type GETFN: HRULE.GE” in a bold frame as shown in FIG.
TFN ”on the display screen.

Thus, the user can be notified that the partial object that cannot be processed by the electronic document editing apparatus is included in the text object 1. Also,
At this time, the respective display contents corresponding to the other partial objects 1-1 and 1-3 that can be processed, that is, the character string "start" and the character string "end" are displayed on the display screen.

As described above, in the present embodiment, for each of the partial objects constituting the text object 1, the respective functions of the display function name and the handler name of the partial object are searched, and if these functions are present, the partial display information of the partial object Is displayed, and if there is no such function, a message (dummy elephant) is displayed instead of the display content. Therefore, all of the plurality of functions for processing the text object 1 are displayed. Even if it is not set, an error is not displayed, and the display content corresponding to the partial object that can be processed can be displayed, and the fact can be displayed corresponding to the partial object that cannot be processed. .

In the above embodiment, a partial object for displaying a straight line which is a figure is described as an example. However, the present invention is not limited to this example. Assign the corresponding handler name and display function name respectively, search for each function of the handler name and display function name for each of these partial objects, and if these functions are set, display the display contents corresponding to the partial object If the respective functions are not set, a message (dummy elephant) may be displayed.
