Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a text processing device such as a word processor or a personal computer.

[0002]

2. Description of the Related Art In document processing by a Japanese word processor or personal computer, an area is provided in the document so that input / editing can be performed independently in each area.

In such a document processing apparatus, it is possible to specify a layout of a sentence in which an independent format is set for each area.

In addition, such a document processing apparatus is provided with a function of displaying the same image as that at the time of printing on the display screen in order to confirm the image of the created document so that the user can easily understand the print image.

Conventionally, with respect to a sentence in which the format is set for each area as described above, whether the layout as specified can be confirmed on the screen only by the function of displaying the print image, or the character input or the edit operation is performed. According to the above, the layout in the area was changed as required.

[0006]

The method of confirming an image on the screen only with the function of displaying a print image has only a display-only function and cannot be input / edited in that state, which results in a natural operation feeling. It becomes a big obstacle. In addition, when a certain area is set as an operation target, the layout of other areas is not realized and the function is not sufficient.

The method of changing the layout in the area at any time in accordance with character input or editing operation has high visibility of the layout, but since complicated layout processing is performed every time a character is input or an edit command is input. , Responsiveness to the operator becomes slow. Further, since the device must perform complicated processing, the scale of the circuit becomes large.

An object of the present invention is to provide a function capable of confirming the layout of each area to some extent while ensuring a smooth input editing operation by an operator when editing a document in an area provided in a document. There is.

[0009]

According to the present invention, there is provided a sentence processing device, wherein a plurality of areas are provided in a screen, and an independent format is set for each area for input editing. When inputting / editing a sentence in each area, a storage means for pre-storing the input / editing time point for changing the layout according to the set format, and when the input / editing scene appears during the input / editing of the sentence. This is achieved by a sentence processing device having a whole area display means for changing the layout in the area.

[0010]

[Function] The input editing time for changing the layout according to the set format is determined, and the layout is changed at that time. Therefore, complicated layout processing is not performed each time a character is input or an edit command is input. The layout of each area can be confirmed to some extent while ensuring smooth input and editing operations by the operator.

The input editing time for changing the layout according to the set format can be the time when the input editing operation in the area is completed, and when the input editing operation in the area is completed by doing so. Then, the layout of the area can be confirmed.

The input editing time for changing the layout according to the set format can be the time when the area for input editing is further switched from one area to another, and when the area is switched by doing so, The layout of the area can be confirmed, and smooth input / edit operation of another area can be ensured.

The input editing time for changing the layout according to the set format can be set as a time when the character cursor indicating the editing position cannot be displayed on the screen during the input editing of the text. When the character cursor indicating the editing position cannot be displayed on the screen during input editing, the layout of the area is changed and the cursor is displayed, so the layout of the area can be confirmed and the operator can smoothly perform input editing. You can continue the operation.

At the time of starting the input editing operation in the area, the layout of the text in the area is temporarily changed to another layout that makes it easy to input and edit, and it is set when the input editing of the area is finished. By changing to the layout of the format, the layout of the area can be confirmed and the operator's smooth input editing operation can be secured.

FIG. 1 is a block diagram of an embodiment of the present invention.

The input device 11 is an input device such as a keyboard or a mouse operated by an operator. The input queue buffer 12 is a memory that holds an input event from the input device 11 until it is processed. The input processing unit 13 is a module that realizes an input editing function for an input. The display processing unit 14 is a module that displays the content of the document on the screen as a result of the operation. The area partial display processing unit 141 is a part of the function of the display processing unit 14, and is a module for displaying a portion within the area processed as a result of the input editing processing. The cursor display processing unit 142 is a part of the function of the display processing unit 14, and is a module for lighting and erasing the character cursor indicating the input editing position on the screen. The entire area display processing unit 143 is a part of the function of the display processing unit 14,
This module displays the entire area at once. The area switching processing unit 15 is a module that realizes the processing of switching the area in the input processing unit 13 when the processing occurs. The area format information memory 16 is a memory for storing the format information set in the area. The area management information memory 17 is a memory for storing information for managing attributes such as the position and size of each area set in the document. The text code memory 18 is a memory for expanding the document data to be input and edited. The screen image memory 19 is a memory that stores image data to be displayed on the screen.

FIG. 2 shows an example of a screen being edited.

In the example of FIG. 2, there are four areas, area 1, area 2, area 3 and area 4, in the page, and area 1 is currently being edited.

The state of the area management information memory 17 in this state is shown in FIG. Its position X for each region in the document,
It stores Y and sizes WIDTH and HEIGHT.

Further, in the screen example, the positions of the characters in the area are displayed based on various positions. That is, the region 1 is at the center, the region 2 is at the upper left, the region 3 is at the lower right, and the region 4 is
In, the right center is displayed as the reference point. This is because each area has such a format.

FIG. 4 shows the format information. In addition to the alignment position exemplified in the area format, line feed pitch, character spacing, and the like are conceivable. However, since the alignment position is described as an example here, other items are omitted.

Now, consider the case where the character string "ABCDEFGHIJKLMN" is inserted from the state of FIG. 2 according to the present invention.

FIG. 5 shows a flow of the input processing unit 13.

Although the input processing section 13 has processing corresponding to all commands, this flow describes only the part necessary for explaining the embodiment of the present invention.

The input processing unit 13 first checks whether or not an event exists in the input queue buffer 12, and if there is, acquires the event from the input queue. In this case, since the event of "character string insertion processing" exists, it is acquired and the "character string insertion processing" is called (S51).

FIG. 6 shows a flow of "character string insertion".

The character string insertion is started with the character code string inserted in advance stored in the cut buffer. First, it is checked whether or not the character string stored in the cut buffer can be actually inserted into the sentence code memory 18 (S61), and if possible, the character code memory into which the character string should be inserted from the character cursor position at that time. 1
The position address in 8 is obtained (S62). Then, the character string is inserted into the obtained address (S63), the area partial display is designated to update the screen, and the control is transferred to the display processing unit 14 (S64). At this time, in order to specify the display range, the start character address and the end character address of the range are passed to the area partial display processing unit 141. When the display is completed, the cursor display processing unit is designated to turn on the cursor, and the display processing unit 1 is designated.
Control is transferred to 4 (S65).

The flow of the display processing unit 14 is shown in FIG. The display processing unit 14 also has some functions, but only the parts necessary for the explanation of this embodiment are shown here.

The display processing unit 14 instructed by the input processing unit 13 to display the area portion together with the specified range information (start character address and end character address) transfers control to the area portion display processing unit 141 by command branching (S71). .

FIG. 8 shows a flow of the area display processing section 141.

The area partial display processing unit 141 first obtains a line in the area including the designated start character, sets it as the processing target line (S81), and displays the target line (S82). At this time, if there is no area to be displayed, nothing is displayed. When the display ends, if it is not checked whether the displayed line includes the specified end character, the line to be processed is updated to the next line and the process is repeated. If the line is included, the process ends.

Since the area partial display processing unit 141 does not perform complicated layout processing in consideration of the responsiveness to the operator, the display position of the first row of each area is determined in the state of FIG. The characters entered up to here as in Fig. 9 are
The area is folded back with a width smaller than the original area, or the area is projected (there is a margin on the left side in the figure, but it is folded back with 5 characters, and "N" extends beyond the area).

FIG. 1 shows a flow of the cursor display processing section 142.

The cursor display processing unit 142 obtains a line including a character for lighting the cursor, checks whether the line is displayed on the screen, and if so, obtains the position and size of the cursor. Turn on the cursor. In this case, since the line containing the character ("") for lighting the cursor is not on the screen, the lighting of the cursor in FIG. 9 is not performed.

In this state, it is assumed that the operator gives the "redisplay area" command to the system, and the explanation will be continued below.

When the input processing section 13 receives the "area redisplay" command, it gives the display processing section 14 the ID of the target area,
It is instructed to display the entire area (S55).

The display processing unit 14 instructed by the input processing unit 13 to display the entire region together with the designated region ID transfers control to the entire region display processing unit 143 by command branching (S73).

FIG. 1 shows the flow of the entire area display processing unit 143.
Shown in 1.

The entire area display processing section 143 searches the area management information memory 17 from the given area ID to obtain management information (position, size, etc.) of the corresponding area (S11).
1). Next, the area format information memory 16 is searched from the area ID to obtain the format information (alignment position, etc.) of the corresponding area (S11).
2). The document area in the area is calculated from these pieces of information to determine the position of the first line (S113). Display in the area from the calculated position is performed (S114). FIG. 12 shows an example of a screen displayed by changing the layout.

The operator explicitly displays the entire area display processing unit 14
In addition to activating No. 3, the entire area display processing unit 143 can be implicitly activated at the time when the input editing operation is completed, and the layout can be changed even at that time. There will be more ways to check the layout.

Further, by the "page redisplay" command, the entire area display processing unit 143 is displayed by the number of existing areas.
May be called so that the layout can be changed for each area.

As a second embodiment of the present invention, an example in which the layout of the area is changed during the area switching process will be described.

From the state of FIG. 9, it is assumed that the operator points the area 3 with the pointing device. In this case the fifth
Control is transferred to the area switching processing unit 15 by command branching in the figure (S53).

FIG. 13 shows a processing flow of the area switching processing section 15.
Shown in.

In the area switching processing section 15, first, the entire area display processing section 1 described in the first embodiment for the current target area is displayed.
The layout is changed by 43. (S13
1). Thereafter, the area designated by the pointing device is searched from the area management information memory 17 (S132),
Information of the found area is set in the information of the target area, and the processing target area is switched (S133). In this way, if the area switching processing unit 15 is made to store the function of displaying the entire area, the layout is automatically changed when the operator finishes the processing of a certain area and moves to the next area.
The need for issuing a troublesome "area redisplay" command is reduced.

As a third embodiment of the present invention, an example in which a process of temporarily changing the display of a new target region to a certain fixed format during the region switching process is shown in the second embodiment of the present invention. . In the above-described embodiments, when editing processing such as character input is performed in a region below the region such as region 3, the cursor immediately extends out of the region and the input is performed. The letters disappear.

Therefore, the processing of the area switching processing section 15 will be described with reference to FIG.
Do as 4.

From the state shown in FIG. 9, it is assumed that the operator points the area 3 with the pointing device. First, the regular format of the current area, which has been saved in advance, is written back to the area format information memory 16 (S141), and then the layout of the current area is corrected as in the second embodiment of the present invention, and then a new format is created. Information is switched to the target area (S142 to S142).
S144). When the new target area is determined, the area format of that area is temporarily rewritten to the specified value (S14).
5). The area is redisplayed with the specified value (S146).
This state is shown in FIG.

By doing so, it becomes possible to input normally even in the area such as the area 3, and when the area is switched to another area, the display returns to the normal area format. The person does not have to bother with issuing the "area redisplay" command, as in the second embodiment.

As a fourth embodiment of the present invention, an example in which the layout of the area is changed when the character cursor cannot be displayed will be shown in the embodiment of the first invention.

FIG. 16 shows the processing of the cursor display processing section 142.
To change. Similar to the operation described in the explanation of the embodiment of the first invention, the character string "ABCDEFGHIJKLMN"
, The line including the cursor 5 extends beyond the area as shown in FIG. 9 after the area partial display processing unit 141 updates the screen after the character string insertion processing. FIG.
In the processing of the cursor display processing unit 142, when the line including the cursor is not displayed, the entire area is once displayed at the time when it is found (S161), and the cursor is lit again. When the characters are inserted in this case, the state shown in FIG. 12 is automatically set, and the operator does not need to explicitly issue a display command in the expectation of a layout change.

As described above, according to the present invention, complicated display processing is not performed during input editing processing in areas having various area formats, and a display such as a print image is displayed. It is not a specialized function, but allows you to check the layout while maintaining a natural input feeling to some extent. In the third and fourth embodiments of the invention, the method for reducing the complicated operation of the operator has been described.

[0053]

As described in detail above, according to the present invention, it is not necessary to perform a complicated layout process every time a character is input or an editing command is input, while ensuring a smooth input / editing operation by the operator. You can check the layout of each area to some extent.
