Abstract

PURPOSE:To display a cursor at its last position when the cursor display device is put back into its last input mode by displaying and outputting the cursor on a display screen according to cursor information stored as start cursor information. CONSTITUTION:When a 2nd input mode is switched back to a 1st input mode, a 2nd storage control means 3 erases cursor information on a cursor storage means 1 corresponding to the 2nd input mode and re-sets cursor information corresponding to the 1st input mode as start cursor information. A cursor display control means 4 displays the cursor on the display screen according to the cursor information stored on the cursor storage means 1 as the start cursor information. Consequently, even if the current mode is changed during processing, the cursor can be displayed at its last position when the mode is reset to the last input mode.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cursor display device used in word processors, personal computers, and the like.

[Prior Art] In recent years, word processors have become more and more multifunctional, and in addition to the original document creation function, word processors are known that have an address book function, a schedule management function, and the like.

In this case, in the input mode of the document creation function, if the mode is changed to another input mode while inputting and creating document data, the cursor that was displayed before the change will be deleted and the cursor displayed after the change will be The cursor was displayed at a new position corresponding to the input mode, prompting users to enter data at that position.

[Problem to be Solved by the Invention] Even if the interrupt input mode is temporarily changed in this way, the cursor that was displayed before the change is erased, so the cursor must be restored to the original mode after the interrupt input processing is completed. When changing to input mode, it is necessary to reset the cursor to its original position, which is cumbersome, and it is difficult to forget the original cursor position and reset the cursor to its original position. There were cases where this happened. In particular, this becomes even more difficult when forced interrupt processing is activated to automatically display the contents of the schedule when the scheduled time is reached.

The problem with this invention is that even if the mode is changed to another mode while processing is being executed in the current input mode, the cursor can be displayed at the original position when the original input mode is returned. It is to do so.

[Means to solve the problem] The means of this invention are as follows.

Cursor storage means 1 (see the functional block diagram in Figure 1)
(the same applies hereafter) is a cursor management memory that stores cursor information indicating the current position of the cursor, etc.

The first storage control means 2 suspends the cursor information in the cursor storage means 1 corresponding to the first input mode when the mode is changed to the second input mode during execution of processing in the first input mode. The cursor is held as a cursor (an idle cursor that does not display a cursor), and the cursor information corresponding to the second input mode is stored in the cursor storage means 1 as an activated cursor (a current cursor that displays a cursor).

When the mode is returned from the second input mode to the first input mode V, the second storage control means 3 erases the cursor information in the cursor storage means 1 corresponding to the second input mode, and also deletes the cursor information in the cursor storage means 1 corresponding to the second input mode. The cursor information corresponding to the input mode of is restored as the starting cursor.

The cursor display control means 4 displays and outputs a cursor on the display screen based on cursor information stored as an activated cursor in the cursor storage means 1.

[Work] The operation of the means of this invention is as follows.

Now, suppose that the mode is changed to the second input mode while processing is being executed in the first input mode. In this case, the first storage control means 2 causes the cursor information in the cursor storage means 1 corresponding to the input mode before change (first input mode) to be held as a paused cursor, and the cursor information corresponding to the second input mode Cursor information is stored in a cursor storage means l as an activation cursor. In other words, even if the mode is changed, the cursor information corresponding to the input mode before the change is not erased, and the cursor information corresponding to the input mode after the change is newly registered, so the cursor information is stored. In the means 1, input information corresponding to the input mode before and after the change is stored, respectively. In this case, data indicating a dormant cursor and an active cursor may be added to the corresponding cursor information. As a result, the cursor display control means 4 displays and outputs the cursor on the display screen based on the cursor information stored as the activation cursor in the cursor storage means l, so that the cursor on the display screen is set to the changed input mode. It corresponds to

When the process in the second input mode is finished and the mode is returned to the first input mode, the second storage control means 3 stores the cursor storage means l corresponding to the second input mode.
The cursor information in the input mode is erased, and the cursor information corresponding to the first input mode is restored as the activation cursor. In this case, since the cursor information corresponding to the first input mode is information indicating the cursor position at the time of mode change, the cursor display control means 4 restores and displays the cursor at the position at the time of mode change based on this cursor information. let

Therefore, even if the mode is changed to another mode while processing is being executed in the current input mode, the cursor can be displayed at the original position when the original input mode is returned.

[Example] An example will be described below with reference to FIGS. 2 to 10.

FIG. 2 is a block diagram showing the basic configuration of a word processor.

The CPU II controls various operations of this word processor according to microprograms stored in the ROM 12, takes in document data input from the key input section 13, provides it to the display control section 14, and displays the text on the CRT display section 15. Display output from the screen, RAM1
6. Performs document creation processing to be stored in 6. In this case, in this embodiment, in addition to the normal document creation mode, there are various input modes such as an address book mode and a schedule mode, and the normal document data is stored in the document memory 16-1 of the RAM 16, and the address The record data is stored in the address book memory 16-2, and the schedule data is stored in the schedule memory 16-3.

The cursor management memory 17 is configured to store cursor flags in addition to the cursor management table CT, and the CPU II updates the cursor management table CT while updating the value of the pointer 18.
The contents of T are searched and the cursor information is registered in the cursor management table CT or the cursor information is deleted from the cursor management table CT.

The cursor management table CT is structured as shown in FIG.

That is, the cursor management table CT has a total of 12 lines, and each line is provided with an area for storing cursor information corresponding to a cursor ID and a stack counter value. Here, the cursor ID specifies the type of cursor displayed on the same screen. For example, the cursor ID is ro.
1J indicates a text cursor, and "02" indicates a layout cursor. Note that if "rFF (hexadecimal number)" is set as the cursor ID, this indicates that cursor information is not set in the corresponding area. Further, the stack counter value indicates whether the corresponding cursor information is a dormant cursor or an active cursor, and in the case of a dormant cursor, indicates the dormant level. That is, when the stack counter value is "00", it indicates the activation cursor, "01", "02", etc.
..., it shows the pause cursor and "01",
The pause level (pause level 1, pause level 2, etc.) of the pause cursor is shown in correspondence with "02"... In addition, the cursor information is the size, and the device information consisting of the position information is the xY coordinate value from the starting point of the display screen, and the size is the length in the horizontal and vertical directions from this position information, as shown in Figure 2. show.

Next, the operation of this embodiment will be explained.

FIG. 4 is a flowchart showing the operation when the mode is changed to another input mode while processing is being executed in one input mode.

Now, while a certain process is being executed (for example, during normal document creation process) (step AI), the CPU 11 determines whether the mode has been changed to another input mode before the process ends (No in step A2). (Step A3). Now, if the input mode is not changed, the process returns to step A1 and the above operation is repeated until the process ends. However, if the input mode is changed before the process ends, the process advances to the next Stella 7'A4 and the mode is changed. A cursor registration process, which will be described later, is executed in order to register cursor information indicating the next cursor position etc. in the cursor management table CT in the cursor management memory 17 as a starting force.

Then, the processing moves to the new input mode that has been changed (for example, address book mode) (step A5), and until this interrupt processing is completed (YES in step A6), it is checked whether or not the input mode has been changed in the same way as described above. (Step A7)
. Here, if there is a change in the input mode again, after performing the cursor registration process (step A8) in the same way as described above,
The process moves to the changed input mode (step A9).

The interrupt processing in this case is the first processing (step AI
) is the second interrupt processing. For example, if you change to address book mode during the initial document creation process, when the schedule time arrives during the address book mode and the mode is forcibly changed to schedule mode in order to display and output the schedule contents. This is alarm processing.

When the second interrupt processing is started, in this embodiment, in order to prohibit further interrupts, the process waits until the interrupt processing is finished (step Al0), and when the processing is finished, the process proceeds to step All. , the cursor information regarding the second interrupt processing is deleted from the cursor management table CT, and then the process returns to the first interrupt processing. Note that this cursor deletion process (step A11) will be described in detail later.

Then, when the first interrupt processing is finished, step A6
This is detected in step A12, and the cursor information regarding the first interrupt processing is sent to step A12.
After deleting from the cursor management table CT in the same way as
Return to the original process (step AI). In this case, the cursor information stored in the cursor management table CT is restored as the activation cursor, and the cursor is displayed based on the cursor information.

Next, the above-mentioned cursor registration process (steps A4, A,
8) will be explained with reference to FIG.

First, set the initial value to the pointer 18 in step B1.
), cursor management table C based on this pointer value.
Specify the address T, and the cursor ID of the specified area is rFF
If not J (No in step B2, perform increment processing to add r14 to the value of pointer 18 (step B3), return to step B2 from step B4 until the value becomes the final address value of the cursor management table CT, The process of searching for an empty area where the cursor ID is rFFJ, that is, no cursor information is written, is repeated.

Here, when the first free area in the cursor management table CT is searched, new cursor information after changing the input mode is stored in the free area (step B5). In this case, a cursor ID corresponding to the type of cursor is also written in the search area. And next step B
Proceed to step 6 and set the stack counter value in the search area to r-I.
Press J to store.

In this way, the cursor information is stored in the cursor management table C.
After new registration to T, next is stack processing (step B7
Proceed to ~B11).

That is, initialize the value of the pointer 18 (step B7),
The cursor ID in the area addressed by this value is r
If it is not an FFJ (NO in step B8), "1" is added to the stack counter value in the area (step B8).
9). Then, step B updates the value of pointer 18.
IO), returns from step Bll to step B8 until the value becomes the final address of the cursor management table CT, searches for an area where the cursor ID is not rFFJ, and sets "1" to the stack counter value in the search area. The addition process is repeated (step B9).

6 and 7 are diagrams showing specific examples of the cursor management table CT when the cursor registration process shown in FIG. 5 is performed. Here, it is assumed that cursor information as shown in FIG. 5 is registered in the cursor management table CT before the mode change. In this case, when the cursor registration process accompanying the first interrupt is performed, the third line of the cursor management table CT is searched as a free area (step B2), as shown in FIG. new cursor information is newly registered (step B5)
. Also, the stack counter value in this area is set at step B6.
After being r-IJed at step B9, it is incremented by "+1", so it becomes "00" indicating the activation cursor. In addition, the stack counter values of the cursor information before the change (the cursor information on the first line and the second line) are changed from "00" to "01" as a result of "r+l" in step B9, and the sleep level l It becomes a pause cursor.

Further, when the cursor registration process accompanying the second intrusion is performed, the contents of the cursor management table CT become as shown in FIG. In this case, the stack counter values in the first and second lines each become "02", and the sleep level is updated to become a sleep cursor of sleep level 2.

FIG. 8 shows the cursor deletion process (step Bll,
It is a flowchart specifically showing B12).

First, the pointer 18 is initialized (step C1), and the cursor ID is rFF from the beginning of the cursor management table CT.
” (step C2). Now, in the case shown in FIG. 7, since the cursor ID "01" is set in the first line of the cursor management table CT, the process advances to the next step C3 and the stack counter value "O" of the area concerned is set.
'0''. In this case, the counter value is “02
'', the process advances to step C7, and the stack counter value is incremented by ``1''. As a result, the stack counter value on the first line is changed from "02" to "01". Then, the value of the pointer 18 is updated in step C5.
), if the value is not the final address, the process returns from step C6 to step C2. As a result, the stack counter value on the second line is also changed to "01". Similarly, the stack counter value on the third line changes from "01" to "OO". and,
The area on the fourth line is addressed, but in this case, the stack counter value is r O' OJ, so step C
If the answer is YES in step 3, the process advances to step C4, where all cursor information in the area is erased.

Note that the cursor IDs from the fifth line onward are all "FF", so the value of the pointer 18 is simply updated until the value of the pointer 18 reaches the final address, and the process ends when the value of the pointer 18 reaches the final address.

Through such cursor deletion processing, the contents of the cursor management table CT shown in FIG. 7 become as shown in FIG. 6. Similarly, when the cursor deletion process is performed with the contents of the cursor management table CT shown in FIG. 6, the contents of the cursor management table CT become as shown in FIG.

FIG. 9 is a flowchart showing a cursor display operation accompanying manual key processing.

First, use the cursor on process to highlight the cursor (
Step El), and turn on the cursor flag (Step E2).

If the cursor is not moved and continues to be displayed at the current position (No in step E3), the process proceeds to cursor blinking and the cursor is displayed in reverse (step E4).
The cursor flag is inverted (step E5).

If the cursor is to be moved and displayed, the process proceeds to cursor off processing, and on condition that the cursor flag is turned on (step E6), the cursor is displayed in reverse video (step E7), and the cursor flag is turned off (step E
8).

FIG. 10 shows the contents of the cursor reversal process (steps E1, E4, and E7) shown in FIG. 9. First, the pointer 18 is initialized and the contents of the cursor management table CT are sequentially searched. Cursor ID as search condition
is not "FF" and the stack counter value is "00" (step DI). The cursor information retrieved by this is read out from the cursor management table CT (step D2), and a cursor of a predetermined size is displayed in reverse video at a position corresponding to the cursor information (step D2).
3).

In this way, the cursor is displayed by referring to the contents of the cursor management table CT, but in this case, the cursor is displayed based on the stack counter value of "00", that is, the cursor information specified as the startup cursor. .

Although the above embodiment is applied to a word processor, it goes without saying that it can also be applied to a personal computer or the like.

[Effects of the Invention] This invention allows the cursor to be returned to its original position even if the mode is changed to another mode while processing is being executed in the current input mode. This eliminates the need to operate cursor keys, which improves operability, and also makes it possible to reliably return the cursor to its original position even if a forced mode change is made.
