Next, each of the above components will be described.

The control module 11 is a module for switching various editing processes and transferring control, and here,
The input state of the user is monitored and the input edit module 13 and the cursor position format information display module 14 are switched.

The user input module 12 is a module that collectively manages key input and mouse input by the user, and temporarily saves input information in an internal buffer.
The input information that has been saved is delivered in response to a request from another module. There is also a function here to monitor if there is any input from the user.

The input / edit module 13 performs various editing operations (character input, deletion, format setting, etc.) according to the user's input, and updates the format information and character information.

Cursor position format information display module 14
Retrieves various information at the cursor position and format information,
Display at the appropriate position on the display device.

The screen display module 15 is a module for collectively carrying out actual screen display processing, and displays designated data at a designated position in response to a request from another module.

The format information buffer 16 stores various format information such as a typeface, character size, line feed pitch, and character spacing.

The character information buffer 17 stores character information which is character code information input by the user.

The cursor position information section 18 is information for managing the cursor state in the document, and manages the cursor position information such as the position and state of the cursor and format information concerning the cursor position.

Next, the processing logic for displaying the cursor position format information by the document editing apparatus of FIG. 1 will be described with reference to the chart of FIG.

As shown in FIG. 2, the document editing apparatus of FIG. 1 determines whether or not there is user input (step S
1) If the user input is determined in step S1, the user input information is extracted (step S
2) Edit operation according to user input (step S
3) If it is determined in step S1 that there is no user input, the process of displaying the edited cursor position information on the screen (step S4) is repeated.

Next, referring to the chart of FIG. 3, FIG.
An outline of processing for displaying cursor position format information by the document editing apparatus will be described.

As shown in FIG. 3, in the cursor position format information display processing by the document editing apparatus of FIG. 1, the cursor position information is retrieved (step T1), various format information of the cursor position is retrieved (step T2), and other display is performed. Necessary information is extracted (step T3), a display character string is created based on the extracted information (step T4), and the created character string is displayed on the display device (step T5).

The operation of the cursor position format information display by the document editing apparatus of FIG. 1 will be described with reference to FIG.

FIG. 4 shows a case where the cursor is moved down three lines from the current position by continuing to press the cursor movement key.

FIG. 4A shows the initial state, and the cursor is on the first line. At this time, various information on the cursor position is displayed in the window for displaying the cursor position format information, and the number of lines at the cursor position is the first line.

FIG. 4B shows a state in which the cursor has moved down by one line, and the number of lines of the cursor remains at the first line.

FIG. 4C shows a state in which the cursor has moved one line down, and the number of lines of the cursor is still the first line. Then, as shown in FIG. 4D, when the cursor is moved further down by 3 lines and the cursor movement key is released, the cursor position format information at that time is displayed, and the number of cursor lines is 4th line. Change.

With the document editing apparatus of this embodiment, it is possible to display the format information at the cursor position without reducing the processing speed of input / edit processing.

In the above-described embodiment, the format information at the cursor position can be displayed without reducing the processing speed of the input and edit processing, but it is difficult to obtain a good response speed. This is because all the redisplay processing for reflecting the result of the input is included in the processing according to the input.

Therefore, in the processing according to the input, the redisplay processing for reflecting the result occupies most of the entire processing time. For this reason, the redisplay process itself may be divided into a redisplay of the directly affected part and a redisplay of the indirect affected part for processing.

Next, a second embodiment of the document editing apparatus of the present invention will be described with reference to FIG.

The document editing apparatus of this embodiment uses a cursor position format information display method that can handle a case where a character string is selected and the character size is enlarged. By enlarging the characters, the line containing the enlarged characters can display only a smaller number of characters than before the enlargement. For this reason, the process of sending the characters overflowing from this line to the next line and sending the characters overflowing due to this sent character to the next line is sequentially repeated. In this example, the line itself in which the characters are enlarged is directly affected by the editing operation, and the lines after which the characters are forced to be sent out are indirectly affected.

Separating processing by direct influence and indirect influence means
The part that is directly affected is re-displayed as part of the response process to the user input, and the part that is indirectly affected means that the gap between user inputs is sewn to proceed the re-display. This makes it possible to carry out the next editing operation without waiting for all the edited results to be reflected on the screen.
Such a processing method is particularly effective when characters are continuously input.

FIG. 5 shows an outline of processing for displaying the cursor position format information when the direct and indirect influence range redisplay processing is divided and processed.

In the process of FIG. 5, it is determined whether or not there is a user input (step U1). If it is determined that there is a user input in the above step U1, the user input information is taken out (step U2) and the user input Performs internal processing (update of buffer data, etc.) according to the input (step U
3) Directly redisplay the affected area (step U
4) If it is determined in step U1 that there is no user input, the information of the edited cursor position is displayed on the screen (step U5), and the indirect influence range is displayed again (step U6). repeat.

According to the cursor position format information display method shown in FIG. 5, a better response time than that of the first embodiment can be realized.

With the document editing apparatus of this embodiment, the cursor position format information can be displayed without lowering the processing speed of the input / edit operation, and the user can maintain comfortable responsiveness to the edit operation. .

The second embodiment is the same as the first embodiment except for the main control logic described above, and therefore its explanation is omitted.

[0048]

As described above, the document editing apparatus of the present invention executes only the detecting means for detecting the input information and the response processing of the input information when the input information is detected by the detecting means, and the input information is no longer detected. Since the control means for controlling the display means to display the format information of the cursor position at times is provided, the cursor position format information display can be executed by utilizing the input waiting time of the user. Documents can be efficiently edited without reducing the processing speed of the function.
