BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display information editing device for displaying information stored in a file on a display screen and editing the information in accordance with instructions from a user.

0002

2. Description of the Related Art In this type of display information editing device, a file is formed in a storage device, and information representing, for example, a document created on a display screen can be stored in the file. You can also load a document from a file as desired, display the document on the display screen, proofread this document, delete a part of the document, or load the document from another file. You can perform editing processing such as copying a document.

[0003] In such editing processing, if there are a large number of files to be edited, the operation becomes complicated, and there is a risk that information in the files may be destroyed due to an erroneous operation.

[0004] For this reason, conventional display information editing devices include:
Some devices have a mode that prohibits changing the information stored in a file, and if this mode is set for a desired file, even if information can be read from the file, the file It becomes impossible to change the information inside. For example, in the vi editor (editing function) used on the UNIX operating system,
If a variable called "readonly" is set for a desired file, information can be read from the file during editing, but modification of this information is prohibited. In addition, in the EMACS editor, “toggle-rea”
By using the command called "d-only",
It is possible to switch between a mode that prohibits modification of information stored in a desired file and a mode that allows modification of the information.

[0005] However, in all of the above examples, changes to information are prohibited in file units, and changes to only a part of the information stored in a file are prohibited, and changes to other parts are prohibited. There was nothing I could do to make it possible. For this reason, for example, if a prescribed document that does not require modification and a mutable document that can be changed as desired are stored in one file, the prescribed document can be protected from destruction due to erroneous operation, and It was not possible to edit the mutable document. That is, when changing information stored in a file, even if it is desired to avoid changing a part of the information, this part is exposed to the risk of being destroyed due to erroneous operation.

[0006]

[Problems to be Solved by the Invention] As described above, in the conventional display information editing device, changing the information in the file is prohibited on a per-file basis. It is not possible to perform processing freely, and therefore, there is a problem in that during editing processing, a part of the information that is not desired to be changed is exposed to the risk of being destroyed due to erroneous operation.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a display information editing device that can freely perform editing processing while prohibiting changes to a portion of information within a file.

[0008]

[Means for Solving the Problems] In the present invention, a portion of information stored in a file is specified as a non-editable portion by a specifying means, and the non-editable portion specified by the specifying means is edited. The designation of the non-editable portion can be canceled by a canceling device so that the non-editable portion can be edited, and the editing prohibition device can cancel editing of the non-editable portion when the non-editable portion is specified. I'm trying to ban it.

[0009]

According to the present invention, since editing of non-editable portions is prohibited, when editing information in a file, the portions will not be changed due to erroneous operation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a display information editing apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an embodiment of a display information editing device according to the present invention. In the figure, an external storage device 1 is a large-capacity storage device including a magnetic disk, a semiconductor memory, etc., and stores a large number of files each storing information, various data, and the like. The keyboard 2 is operated to input various data, and the mouse 3 is operated to specify a desired position on the display screen. Input control device 4
transmits various data, commands, etc. to the editing device 5 in response to the operation of the keyboard 2, and transmits data indicating a position on the display screen to the editing device 5 in response to the operation of the mouse 3. In response to input from the keyboard 2 and mouse 3 via the input control device 4, the editing device 5 searches for a predetermined file in the external storage device 1 and searches for documents, graphics, etc. stored in the file. This information is displayed on the display device 7 through the display control device 6. Also,
The editing device 5 performs editing processing such as creation, deletion, copying, etc. on the document displayed on the display device 7 in response to input from the keyboard 2 and mouse 3 via the input control device 4. The display control device 6 controls raster scanning and the like on the display device 7.

Furthermore, the editing device 5 includes a designation control unit 51 for designating the part of the document displayed on the display screen of the display device 7, and a designation control unit 51 for designating the part of the document that is designated by the designation control unit 51 as being uneditable. Specified area storage unit 52 to store as an area
, a release control unit 53 that erases the non-editable area stored in the specified area storage unit 52, and an edit prohibition control unit 54 that prohibits editing processing on the non-editable area stored in the specified area storage unit 52. and is provided.

Next, the operation for specifying the part of the document displayed on the display screen of the display device 7 will be described with reference to the flowchart shown in FIG.

First, a predetermined file is designated by operating the keyboard 2, and the display of information within this file is instructed. In response, the editing device 5 searches for the file in the external storage device 1 and displays the information in this file on the display screen of the display device 7. As a result, a document as shown in FIG. 3, for example, is displayed on the display screen of the display device 7.

[0015] On this display screen, along with the document, a menu 31 labeled "Editable" and a menu 32 labeled "Editable" are displayed at the top. Further, the caret 33 indicates the input position of characters, symbols, etc., and when characters, symbols, etc. are input by operating the keyboard 2, the characters, symbols, etc. are displayed at the position of the caret 33, and accordingly, the caret 33 The position of is incremented one character at a time. Furthermore, the cursor 34 is used to move to any position on the display screen in accordance with the operation of the mouse 3 and to indicate a desired position.

On such a display screen, if there is a part of the document that you would like to designate as a non-editable area, move the cursor 34 to the beginning position A of the area by operating the mouse 3 (step 101); The button 35 attached to the mouse 3 is pressed.

The specification control unit 51 in the editing device 5 determines whether the button 35 of the mouse 3 is pressed through the input control device 6 (step 102), and when this determination is made, the cursor 34
Find the position on the data indicating the document corresponding to position A,
A variable A' indicating the position on the data is set (step 103).

After specifying the starting position A of the document part in this way, the cursor 34 is moved to the trailing position B of the document by operating the mouse 3 while holding down the button 35 of the mouse 3 (step 104). ), release button 35 of mouse 3. The specification control unit 51 determines through the input control device 6 that the button 35 of the mouse 3 has been released (step 105), and upon making this determination, determines the position on the data indicating the document corresponding to the position B of the cursor 34. , a variable B' indicating the position on the data is set (step 106
).

Next, the designation control unit 51 performs the step 10 described above.
It is determined whether the variable A' indicating the leading position set in step 3 is the same as the variable B' indicating the trailing position set in step 106 (step 107). Here, if the variable A' and the variable B' are the same, the leading position and the trailing position are the same, and therefore there is no area between the two positions. In this case, the specification control unit 51 deletes the variable A' and the variable B' and ends the process without specifying the part of the document.

Further, if it is determined in step 107 that variable A' and variable B' are not the same, since there is an area from the head position to the tail position, the specification control unit 51 selects variable A' and variable B'. Specify the region corresponding to ', that is, the part of the document.

The editing device 5 inverts the black and white of part a of the document specified by the variables A' and B' as shown in FIG. Part a is clarified (step 108).

[0022] Once the desired part a is designated in the document displayed on the display screen of the display device 7, this part a can be made an uneditable area according to the process of the flowchart shown in FIG. .

To do this, first move the cursor 34 to the menu called "Cannot edit" displayed at the top of the display screen by operating the mouse 3 (as shown in FIG. 6), and then 3. Press button 35 once. Here, since the button 35 of the mouse 3 was pressed while the cursor 34 was in the area of the menu called "non-editable", the editing device 5 determines that the menu has been selected (step 201), and selects It is determined that the displayed menu is a menu called "non-editable" (step 202).

[0024] Then, when the editing device 5 determines that the menu called "editing not possible" has been selected, it notifies the designation control section 51 of this fact. The designation control unit 51 determines whether a predetermined area is currently designated on the display screen, that is, whether a variable indicating the area is set (step 203). Here, variables A' and B' are set, and part a of the document shown in FIG. 6 specified by these variables is displayed in black and white inverted.
The process moves to the next step 204. Note that if each variable is not set, this process ends.

In step 204, the designation control section 51 stores the variable A' and the variable B' in the designated area storage section 52 (step 205). At this time, the editing device 5 cancels the black-and-white inverted display of part a of the document shown in FIG. 6, and returns to the normal display of black characters on a white background.

A list as shown in FIG. 7 is stored in the specified area storage unit 52, and the variables A' and B' are initially set, for example, to specify a portion of a document. If so, it is stored corresponding to the non-editable area S1. Note that it is possible to set multiple non-editable areas for one document; in this case, the second, third,
A set of variables specifying each area is stored in a list corresponding to each non-editable area S2, S3, . . . set in .

Once the variables A' and B' are stored in the specified area storage unit 52 in correspondence with the non-editable area S1, when the editing device 5 performs the editing process, the editing prohibition control unit 54 prohibits the editing process. It is monitored and restricted so that the caret 33 (shown in FIG. 6) does not enter part a of the document indicated by variable A' and variable B' in the specified area storage unit 52. This moves caret 33 to part a of the document.
Even if you try to insert the caret 33 into the part a
You will have to move by jumping and avoiding it.

If the movement range of the caret 33 is restricted so that it does not enter part a of the document in this way, it is not possible to add or delete characters, symbols, etc., copy, etc. to this part a. will not be changed due to erroneous operations during the editing process, and will be protected from the risk of destruction.

Next, a process for restoring part a of the document, which has been designated as an uneditable area, to the original state so that it can be edited will be described with reference to the flowchart shown in FIG.

First, a desired portion of the document is designated by performing the processing shown in the flowchart shown in FIG. For example, if part a of the document is specified as shown in FIG. 4, this part a will be displayed in black and white inverted.

Subsequently, by operating the mouse 3, the cursor 34 is moved to the menu called "Editable" displayed at the top of the display screen (as shown in FIG. 8), and then the button 35 of the mouse 3 is moved. Press once. Here, since the button 35 of the mouse 3 was pressed while the cursor 34 was in the area of the menu called "editable", the editing device 5 determines that the menu has been selected (step 201), and selects the menu. It is determined that the displayed menu is a menu called "editable" (step 202).

When the editing device 5 determines that the menu labeled "editable" has been selected, it notifies the release control section 53 of this fact. The release control unit 53 determines whether a predetermined area is currently designated on the display screen, that is, whether variables A' and B' are set by the designation control unit 51 (step 205). Here, variables A' and B' are set, and part a of the document specified by these variables as shown in FIG. 8 is displayed in black and white inverted. Step 20 of
Proceed to step 6. Note that if each variable is not set, this process ends.

In step 206, the cancellation control section 52 searches the list shown in FIG. Determine whether it is stored in the . Here, if the variables A' and B' are not stored in the list, this process ends. Also, each variable A', B
If ' is stored in the list, the release control unit 52 deletes each variable A' and B' from the list (step 207).
.

In this way, each variable A is stored in the specified area storage section 52.
If ', B' are deleted, the editing prohibition control unit 54 does not perform the control to prohibit the caret 33 from entering part a of the document, and editing of this part a becomes possible.

As described above, in this embodiment, by setting a set of variables for specifying parts of a document in the specification control section 51 and storing these variables in the specified area storage section 52, the editing prohibition control section 54 prohibits the editing process for the part of the document specified by each variable, so the document can be edited freely while protecting the part of the document from being destroyed by erroneous operation.

Note that when storing the displayed document in a file, the list in the designated area storage section 52 is stored together with the document, and when reading the document from the file, the list is read out and stored in the designated area storage section 52. If it is stored again, there is no need to specify areas that cannot be edited every time the document is read.

By the way, in this embodiment, a document is exemplified as the information to be edited, but the present invention is not limited to this, and the present invention can also be applied to information such as graphics and image data. Needless to say.

[0038]

Effects of the Invention As explained above, according to the display information editing device according to the present invention, when editing information in a file, if a portion of this information is designated as a portion that cannot be edited, this portion of the information cannot be edited. Since editing of the available portion is prohibited, the information can be edited freely while protecting the portion from destruction due to erroneous operation.
