Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing apparatus such as a personal computer or a word processor, and relates to a means for canceling an editing process due to an erroneous operation.

[0002]

2. Description of the Related Art Conventionally, in a document editing apparatus such as a personal computer or a word processor, cancellation operations such as function selection, object designation and edit parameter setting before actually executing the editing process can be individually canceled. It is like this. For example, even when the targets are erroneously specified when specifying a plurality of targets, only the erroneously specified data can be released from the targets.

On the other hand, after the editing process is executed, there is a function called "UNDO" for canceling the immediately preceding editing process in order to restore the document data changed by the erroneous operation. As an implementation method, Japanese Patent Laid-Open No. 1-10066
As described in No. 1, in addition to the means for storing the document data being edited, a second storage means for storing the document data immediately before executing the editing process by the edit command is provided, and the storage means is provided in case of an erroneous operation. There is a method to recover with the document data of.

[0004]

According to the above-mentioned conventional technique, each input operation performed for instructing the editing can be canceled immediately before the editing process is executed, but after the editing process is executed, the document before the editing can be canceled. To recover data,
A series of input operations performed for instructing editing will be invalid. In order to instruct editing, in addition to selecting a function and instructing execution, it is necessary to specify the editing target.In the above-mentioned conventional technology, after the editing is executed, only the erroneous operation part is modified and edited. Even if you do
You have to start over from the beginning. For example, in the figure editing function, multiple figure data can be edited at once, and the operation is performed by specifying multiple targets, selecting the editing function, and instructing execution. Even if you let the process run, or
Even if you make a mistake in selecting the editing function and execute the editing process, you must restart the targeting operation after recovering the data.

The present invention has been made in order to solve the above problems, and an object of the present invention is to simplify the operation for making a correct edit after the data has been changed by an erroneous operation. To do.

[0006]

To achieve the above object, the present invention provides a series of input operations necessary for instructing editing in a document editing apparatus having editing functions such as moving, copying, and deleting. The editing content storing means for storing the editing content, the first reproducing means for returning the editing content of the editing content storing means to the document data immediately before the editing, and the operation for starting the data processing corresponding to the editing content are excluded. Second reproduction means for returning the input operation to the operated state, and instruction means for instructing to operate the first and second reproduction means are provided.

The hardware of the present invention mainly comprises a CPU, an input device such as a keyboard, a mouse and a pen, a display device, a memory such as RAM and ROM, and an external storage device such as a floppy disk and a hard disk.
Further, the document editing means, the editing content storage means, the first,
The second reproducing means, the first and second instructing means are composed of the hardware and its control program, and the document data is stored in the memory.

Further, the first and second instructing means may be instructing means for instructing to operate the first and second reproducing means. Further, although the first and second reproducing means are operated based on the instructing means, means for instructing the suppression of the operation by the second reproducing means may be provided.

[0009]

In document editing, when a series of operations for the editing function are performed from the input device, the function data and coordinate data from the input device are stored as edit contents by the edit content storage means. Also, the document data immediately before executing the editing process is stored. When an instruction to restore the document data immediately before editing from the edited content of the edited content storage means is given by the first means, the first reproduction means erases the current document data and executes the editing process. The above-mentioned data stored immediately before execution is stored as document data. Further, when the second instruction means gives an instruction to return to a state in which an input operation other than an operation for starting data processing corresponding to the edited content is given, the second reproduction means causes the edited content storage means. It operates so as to act as an editing operation based on the edited contents stored in.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a state of an edit screen in which a move operation is executed by mistake, a delete operation is executed by mistake, and then the execution is canceled in the graphic editing according to the embodiment of the present invention. 100, 101, 102103 are edit screens, 130
Is an input graphic menu, 110, 111, 112, 113
Is a work area for figure editing on each editing screen.

When the user designates the figure 120 displayed in the work area on the edit screen 100 by operating the mouse or inputting the keyboard, the editing apparatus recognizes that the figure 120 is designated and A display indicating that the graphic is targeted is displayed (graphic 121 in the work area 111 of the edit screen 101). Then, the edit screen 10
When the user gives a deletion instruction in the state of 1, the editing device deletes the designated graphic 121 and displays the result after the deletion in the work area 111 of the edit screen 102.

Next, when the user gives an instruction to cancel the execution, the editing device restores the graphic data to the graphic data immediately before being deleted, as shown in the edit area 113 of the edit screen 103, and the graphic data to be deleted is targeted. Returns to the specified state.

An execution cancellation method according to this embodiment will be described with reference to an edit processing flowchart (FIG. 2) for explaining the processing flow of this embodiment and a state management table (FIG. 3) for controlling the processing flow. .

First, the state management table will be described. The state management table includes an editing state management table 310 that stores information for determining whether an editing operation is in progress, a processing state management table 320 that stores information for determining an execution state of an editing process, It comprises a save area 330 for saving document data.

The edit state management table 311 stores information indicating an initial state, a state in which a target is designated (target designated state), or a state in which a function is executed (execution state). 312 stores the number of designated data items,
In 313, the addresses pointing to the designated data are stored by the number of the data. When the target is designated, 311 is set to the target designated state, the number of targets 312 is incremented by 1, and the address pointing to the designated data is stored in 313. On the contrary, when the target designation is released, the address indicating the corresponding data is deleted from 313,
Decrements 312 by 1. At this time, if the target designation number of 312 becomes 0, 311 is initialized. When an instruction (in this embodiment, input of a function) to execute the edit process is given to the object 312 in the object designation state, the element 311 is put into the execution state.

The processing status management table 321 stores information indicating whether the execution of the editing processing has just finished (execution end status) or the status of execution cancellation is instructed (execution cancellation status). To do. Reference numeral 322 stores the number of designated coordinates that have been designated or de-designated from the start of the editing operation, that is, the start of the designation operation until the execution of the editing process is instructed. The minute and the designated coordinates are stored in 323 as a type indicating whether the target is designated or the target is cancelled. When the target designation or target designation release is performed, 322 is incremented by 1, and 323 stores the target designation or target designation release type and 324 stores the target designation and target designation released coordinates. When the editing process is executed, 321 is set to the execution end state. Further, when 321 is in the execution end state and an instruction to cancel the execution is issued, 321 is set to the execution canceled state, and when an operation other than the instruction to cancel the execution is performed, 321 is set to the initial state.

The save area 330 is a storage area for saving the document data immediately before executing the editing process.

Using the status management table described above,
The flow of the editing process including the execution cancel process is performed as shown in FIG.

At the start of processing, the initial states of 311 and 321 are set.

First, the processing up to the object designation will be described. At 200, an input is received from the user, and at 210, the process to be performed next is determined. When the input is target designation target or designation release, 322 is incremented by 1, and 323 stores the type of target designation or target designation release, and the target designation or target designation release coordinates in 324. Two
At 10, if the input is the target designation, the process proceeds to step 221, and if the target designation is released, the process proceeds to step 222. Process 221
Then, the number of targets 312 is incremented by 1, the address pointing to the data designated as the target is stored in 313, and 311 is brought into the target designation state in the processing 231. In process 222, the address indicating the corresponding data is erased from 313, 312 is decremented by 1, and in process 232, if the designated number of targets of 312 becomes 0, 311 is initialized. 23
After processing 1 and 232, the processing shifts to processing 240 and processing 2
At 40, the state of 311 is judged. In process 240, 3
If 11 is the execution state, the process proceeds to the process of executing the edit process after 250. However, after the processes of 231, 232, since 311 is the initial state or the target designation state, the process is shifted to the process 270. Let In process 270, the result of target designation or target designation release is displayed. After the processing 270, the processing shifts to 200 again.

Next, the processing from the designation of the object to the execution of the editing processing will be described. When a function is input, 20
The processing shifts to 223 through the processing of 0 and 210. In 223, 311 is set to the execution state, and the state determination of 311 in process 240 causes the process to shift to the process of executing the edit process after 250. In the process 250, first, the document data is saved in the save area 330 and 313
The editing process corresponding to the input function is executed on the data pointed to by the address. The data to be edited is the same as the number of 312 objects. After executing the edit process in 250, in process 260, 311 is initialized to 312.
Is set to 0. Further, 321 is set to the execution end state, and the process 2
At 70, the editing process result is displayed.

Next, a description will be given of the processing after the above-mentioned editing processing, that is, when the execution cancellation is input when 321 is in the execution end state. When the execution cancel is input, the processing shifts to 224 through the processings 200 and 210. In 224, 311 is set to the execution state, 321 is set to the execution cancel state, and the state determination of 311 in the process 240 causes the process to shift to the process of executing the edit process after 250. In process 250, the data in the save area 330 is recovered as document data, and the process is transferred to the processes of 260 and thereafter. In process 260, 311 is set to the initial state, and in 270, the recovered document data is displayed as the execution cancellation result, and the process proceeds to 200. If 321 is the execution cancel state, the 200 performs the next process without accepting an input from the user until the coordinate number of 322 becomes 0. The 200 reads the type of 323 and the coordinates of 324, and shifts to the processing of 210 and subsequent steps as an input from the user. At this time, the number of coordinates of 322 is decreased by 1, and when 322 becomes 0, 321 is initialized. By this processing, the target designation or target designation release processing is repeatedly performed for the number of coordinates of 322 in the processing 210 and thereafter, and when the user input is accepted in 200, the document data immediately before the editing processing is restored. ,
Returns to the specified state.
