Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scroll control device and a display device which can quickly display a desired area when the size of a logical screen is larger than the actual screen.

For example, in a device for displaying a form screen and inputting form data to a predetermined item, when one form screen cannot be displayed on one screen, the operator moves the form screen up, down, left and right in the window ( (Scrolling) to display a predetermined input area and input data.

In this scroll, when the cursor is moved to the end of the input area and the cursor is moved in that direction, the screen is displayed while the relative positional relationship between the input area and the cursor position is maintained. It is said that a new screen appears by moving in the direction opposite to the cursor movement operation direction, but if the amount of scrolling once is 1 line and 1 digit, the scrolling time until the desired input area is displayed becomes longer. .

For this reason, on a screen for inputting form data, etc., the amount of scrolling once is set to, for example, one line and four digits, and the scroll time is scrolled by one line in the up and down direction and by four digits in the left and right direction. It is shortening.

However, when the amount of movement from the current screen becomes large, for example, when focusing on a specific input item (or output item) of a large number of input forms, it is convenient to input data in order. However, the scroll amount of one line and four digits is insufficient as the unit scroll amount, and even in such a case, a simple means for shortening the scroll time is required.

[0006]

2. Description of the Related Art FIG. 9 is a diagram showing a scroll method (No. 1), and FIG. 10 is a diagram showing a scroll method (No. 2).

FIG. 9 (1) shows an example of a basic unit scroll in the horizontal direction. When the logical screen k is larger than the actual screen n0, and the input area of item A (underlined part, the same applies below). Shows the case where continues to the outer right side of the real screen n0.

Now, when data is entered in item A and the cursor is at the position of a, one more character is entered to scroll horizontally by 4 digits, and the area indicated by the real screen n1 in the logical screen k is displayed. Is displayed. At this time, since the cursor position indicates the next input position, it is one digit right on the logical screen (position b).
, And on the actual screen n1, it apparently moves to the left by three digits.

As described above, the input position is at the right end of the input area, and when one digit of data is further input, four digits are scrolled in the horizontal direction. Therefore, the input area hidden on the screen is displayed at the right end of the screen in units of four digits. As it appears, the operator can easily input data while checking the input area.

FIG. 9 (2) shows an example of the basic unit scroll when the input area of the item B to be input next is on the right side of the item A and the input of the item A is completed. In this case, first, four digits are scrolled to the right, but since the input area of item B does not appear, the rightward cursor key is further pressed. In this way, when 4-digit scroll is insufficient,
Two scroll operations will be performed.

When the cursor is not located at the boundary of the input area and the cursor key is pressed, the cursor moves only and scrolling is not performed. That is,
When the cursor is positioned at the top, bottom, left, or right boundaries of the input area, or at the top, bottom, left, or right edges of the actual screen, and when the cursor is moved in a direction that protrudes from those boundaries, or when the cursor is moved by data input. , The above scrolling is performed.

FIG. 9 (3) shows a case where the number of correction digits is 4 in the horizontal screen unit scroll. In this scrolling method, when scrolling by one screen, the screen is overlapped with the screen four digits before.

When this screen-by-screen scroll is used, item B is displayed by one scroll operation. Of FIG.
(1) shows an example of vertical scrolling, and since data is often input line by line in forms etc., the scroll amount is set to 1 line. In this case, no matter where the cursor is in the input area of item A,
Scroll one line by pressing the direction cursor key.

FIG. 10 (2) shows an example of vertical screen-by-screen scrolling, in which one screen is scrolled upward (or downward) as a correction line of one digit. According to this method, even if the lines are separated by several lines like the item C, the input area of the item C can be displayed by one scroll operation.

As described above, there are a basic unit scroll and a screen unit scroll as the scroll amount by one scroll operation. In the former case, one line and four digits are set, and in the latter case, the correction amount is set as one line and four digits. Therefore, when performing a certain form process, the operator specifies as if there is a basic unit scroll or as a screen unit scroll. As a result, the preset scroll amount of one line and four digits is used and scrolling is performed.

FIG. 10 (3) shows the minimum scroll, which is used when data is sequentially input to all input areas and is executed when neither basic unit scroll / screen unit scroll is specified. It is something.

The minimum scrolling is such that the cursor moves by one digit each time data is input, and when the data is input at the last digit, the cursor is displayed at the beginning of the next input area (actual screen. In the case of n4), there is an advantage that a scroll operation is unnecessary when continuously inputting data.

As described above, scrolling includes basic unit scrolling, screen unit scrolling, and minimum scrolling. When the operator displays a text format file, basic unit scrolling and screen unit scrolling are enabled / disabled. By specifying none, the scroll method is adopted.

In the examples shown in FIGS. 9 and 10, the cursor position moves on the real screen as the input area moves by scrolling. Therefore, the cursor may disappear from the actual screen depending on the scroll amount. In this case, when the input area of interest is pointed with a mouse or the like and clicked, the cursor is displayed at that position, so that data can be input to that input area.

[0020]

The above-mentioned conventional basic unit scroll amount is fixed at 1 line and 4 digits, and the screen unit scroll amount is fixed at correction amounts such as 1 line and 4 digits, and the user cannot arbitrarily specify it. could not. The reason for this is that if the settings can be arbitrarily set, when the form type to be processed changes, unless the optimum scroll amount is specified each time, it may take a long time to scroll, which is an operational reason.

On the other hand, on the other hand, for example, when it becomes necessary to correct only an input item having a large number of forms or to refer to an output item, the fixed scroll amount is
There is a problem that the amount of scrolling once is insufficient and the scrolling time becomes long.

In view of the above problems, the present invention can easily specify an arbitrary scroll amount while maintaining the advantage of fixed scroll amount specification, and even in that case, it is possible to realize the minimum scroll to a non-input area. It is an object of the present invention to provide a scroll control device that shortens the scroll time.

[0023]

In order to solve the above problems, a scroll control device and a display device according to the present invention, as shown in the principle diagram of the present invention in FIG.

When the first scroll method execution unit 33 is determined, the first scroll method execution unit 33 performs the scroll processing based on the default value of the predetermined scroll amount, and the second scroll method execution unit 33. When the execution unit 34 is determined, the second scroll method execution unit 34 performs the scroll process based on the scroll amount designated by the setting unit 32.

As described above, if the scroll amount is not specified, the default value is used, and if the scroll amount is specified, the scroll amount is used for scrolling. Therefore, the scroll amount can be specified as necessary. If not specified, the preset default value is restored. Therefore, it is not necessary to set the scroll amount each time. Even if the user specifies the scroll amount, the scroll amount must be specified each time. Such operational problems are solved.

If the presence or absence of the basic unit scroll and the screen unit scroll is separately designated as the default value as shown in the conventional example, the minimum scroll operation can be performed without "designation". (2) Second Invention In the first invention, the setting unit 32 has a text format storage unit and a text editing unit. The text editor is

FIG. 2 is a block diagram of the first embodiment, FIG. 3 is a flow chart of a scroll method determination operation, FIG. 4 is a flow chart of a scroll operation, and FIG. 5 is an explanatory view of the first embodiment. [First Embodiment] In this embodiment, a case where a first scroll method execution unit, a second scroll method execution unit, and a third scroll method execution unit are combined is shown. The decision of which scroll method to use is made, for example, at the time when the initial screen is displayed.

In FIG. 2, 1 is a memory, which is a screen definition object.
Logical screen data 2 based on 13 is expanded, basic unit scroll amount 1 line 4 digits, screen unit scroll amount (correction line digit)
A default value 3 of 1 line and 4 digits is set in a predetermined area.

Reference numeral 4 denotes three sets of method flags for notifying the determined scroll method. When the scroll amount is not specified, the flag for the first scroll method is turned on, the scroll amount is specified, and priority is specified. In the case of, the flag for the second scroll method is turned on, and when the scroll amount is designated and there is no priority designation, the flag for the third scroll method is turned on.

Reference numeral 6 is basic / screen information, which is set as basic unit scroll or screen unit scroll. Reference numeral 7 denotes a scroll amount for one scroll instruction, and a default value 3 and a designated value designated by the text file 23 are set in this area.

As described above, when the first scroll method is designated by the method flag 4, the scroll processing is performed with reference to the basic / screen information 6 and the scroll amount (default value is set) 7 as usual. I do.

Similarly, when the second scroll method is designated, the scroll processing is performed according to the basic / screen information 6 and the scroll amount (the designated scroll amount is set) 7.

When the third scrolling method is designated, the screen definition body 13 and the cursor position counter 17 are referred to, and the minimum scroll amount at which the cursor is displayed in the next input area is calculated. The calculated scroll amount is compared with the scroll amount 7 which is the designated scroll amount, and the smaller value is used for scrolling.

Reference numeral 8 denotes a scroll method determining section which searches the text type file 23, detects the presence or absence of the scroll amount designation and the presence or absence of the priority designation, determines the scroll method type, and turns on the corresponding method flag 4. In addition to the setting, the designated scroll amount or the default value is set as the scroll amount 7 in a predetermined memory area in accordance with the method.

An input processing unit 9 creates and develops the logical screen data 2 based on the screen definition body 13, resets the screen position counter 11 and causes the display control unit 14 to display the initial screen (the origin of the logical screen). A screen based on is displayed.) Control data input to the input area.

Reference numeral 11 is a screen position counter, and the origin coordinates of the actual screen are represented by logical screen coordinates. Then, it is updated by the scroll execution unit 10 every time scrolling is performed. 12
Is a text editing section for displaying and updating scroll information of the text type files 22 and 23.

A screen definition body 13 defines fixed literal information such as item names, coordinates of the input area, and the like, and the logical screen data 2 is expanded by these values. A screen memory 16 stores display data for one screen. A cursor position counter 17 stores the cursor position coordinates on the logical screen. Reference numeral 18 is a cursor control unit, 19 is a keyboard, and 20 is a cursor key in four directions of up, down, left and right.

Reference numeral 21 denotes a mouse, which performs control such as moving an arrow or the like according to the movement amount information to display a cursor in the input area. Reference numeral 22 is a text type file in which the user sets basic unit scroll presence / absence information and screen unit scroll presence / absence information. Reference numeral 23 is a text-type file that stores the basic unit scroll amount that can be specified by the user, the screen unit scroll amount, and presence / absence information of priority designation.

With the above structure, the following scroll processing is performed. (Scroll method determination operation) See FIG. 3 (1) Read scroll information from the text file 23. (2) Search the scroll information to see if the scroll amount is specified. (3) If not specified, store the basic / screen information in the basic / screen information 6 storage area and set the scroll amount 7 A default value is set in the storage area, and the method flag 4 for the first scroll method is turned on in the storage area of the method flag 4. (4) If the scroll amount is specified, search whether there is priority specification. (5) When the scroll amount is specified and the priority is specified, the basic / screen type and the specified scroll amount are set in the predetermined area in the memory 1 and the method flag 4 for the second scroll method is turned on. To (6) If the scroll amount is specified but the priority is not specified,
The basic / screen distinction and the designated scroll amount are set in a predetermined area of the memory 1, and the method flag 4 for the third scroll method is turned on.

As described above, the scroll method is determined at the time when the screen is opened, and thereafter the scroll processing is performed by the scroll method. (Scroll Processing Operation) The scroll processing by pressing the cursor key will be described below. See FIG. 4 (1) The input processing unit 9 refers to the screen definition body 13 to generate the logical screen data 2 and resets the screen position counter 11.
Subsequently, one real screen worth of data is extracted from the logical screen data 2 with the screen position counter 11 as a reference, and the display control unit 14 is instructed to display the data.

After that, the cursor position counter 17 is set at the head position of the first input area and the process waits for an event. (2) When any one of the four cursor keys 20 (up, down, left and right) is pressed, the cursor moving direction is determined. (3) At this time, if the cursor position is within the input area and other than the boundary, the cursor position counter 7 is updated to move the cursor position in the direction designated by the cursor key 20, and then the next event waits. (4) If the cursor position is on the boundary of the input area, scroll processing is performed.

First, referring to the method flag 4, if it is the first scroll method without specifying the scroll amount, the basic / screen information is referred, and if it is the basic unit scroll, the cursor key 20
Performs a scroll process of 1 line and 4 digits in the direction indicated by, and in the case of screen unit scroll, a correction amount of 1 line and 4 digits is performed. In this case, the value of the area of the scroll amount 7 in which the default value 3 is set is used as the scroll amount. (5) If no basic / screen is specified, perform minimum scrolling to display the cursor at the beginning of the next input area. (6) In the case of the second scroll method in which the scroll amount is designated and the priority is designated, the scroll process is performed using the designated scroll amount, here the scroll amount 7. The scrolling process in this case is exactly the same as the above process (5). (7) In the case of the third scroll method that does not specify priority, the distance from the cursor position on the current screen to the beginning of the next input area is compared with the specified scroll amount, and the specified scroll amount is smaller. If so, scroll processing is performed with that scroll amount. (8) If the scroll amount is larger, the cursor is displayed in the next input area, that is, the minimum scroll process is performed.

As described above, the scroll amount and the presence / absence of the priority designation in the text file 23 are designated by the text editing section 12, so that the user can easily designate the scroll amount. In particular, when the designated scroll amount is different for each input area, if the maximum scroll amount is designated and priority is not designated, the minimum scroll is performed and a plurality of input areas can be sequentially displayed.

FIG. 5 shows the pattern. The screen of (1) shows the case with priority designation and the screen without priority designation. In this example, there is no priority designation. For example, since the scroll amount is small, the scroll time is shortened as compared with the case where the priority is designated.

FIG. 5B shows the case of scrolling in the order of item A → item Y → item X. If the scroll amount in the up and down direction is Y2, the screen A to the screen B is shifted in the Y direction. The screen is changed to the screen B, but the screen is changed to the screen C in the next scroll, and the item X does not appear. In this case, if the scroll amount is Y1, the screen A to the screen B is scrolled by the minimum scroll, and the next scroll is scrolled by Y1, so that the item X is displayed in the screen D. That is, when it is necessary to specify a plurality of scroll amounts, the maximum scroll amount among them may be specified. The same applies to the lateral direction.

The above description is for the case where the cursor key 20 is pressed, but the same scrolling is performed when data is input. (Second Embodiment) FIG. 6 is an explanatory view of the second embodiment, FIG. 7 is a block diagram of the second embodiment, and FIG. 8 is a processing flowchart of the second embodiment. Note that the same reference numeral represents the same object throughout the drawings.

In the second embodiment, as shown in FIG. 6, the whole or a part of the logical screen is reduced and displayed in a window, and a window frame that can be moved by a mouse or the like is displayed on the reduced display screen. An example in which the screen in the window frame is displayed in another window will be shown. Note that it is not necessary for the windows to be displayed on the same screen,
Of course, either one may be displayed by the operation.

In FIG. 7, reference numeral 26 designates a display range designating unit, which is the entire screen of the logical screen and the window frame of the window.
The window control unit 28 is requested to display the reduced size in the window, and the movement of the window frame is controlled by the movement amount information of the mouse 21.

A screen position counter 27 stores the origin coordinates of the window frame as logical screen coordinates. This value is
In the initial state, the coordinates are the origin coordinates of the logical screen, but they are updated by the display range designation unit 26 based on the movement amount information from the mouse 21.

Reference numeral 28 denotes a window control unit which controls display of a window which is an input screen shown in FIG. 6 and a window which displays a reduced screen. A reduction / expansion unit 29 expands the display data given by a character code or the like into dot data of a predetermined size (here, reduction). This dot data is stored in the screen memory 16 and displayed on the display unit 15.

With the above configuration, the partial screen including the desired item can be displayed in the window by the following operations and processes. (1) First, the logical screen is reduced and displayed in the window. (2) The screen position counter 27 is reset and a window frame having a size corresponding to the window is displayed on the window with the origin of the logical screen as a reference. (3) The logical screen in the window frame is displayed as a real screen in the window and waits for an event. (4) Here, when the window frame moving operation by the mouse 21 is performed, the screen position counter 27 is updated based on the moving amount by the mouse operation. As a result, the window frame of the window is moved and displayed. When the execute button attached to the mouse 21 is pressed, the logical screen in the frame is displayed in the window instead of the initial screen. (5) When the cursor display operation is performed by the mouse 21 as an event, the input processing unit 2 displays the cursor in the input area designated by the mouse 21, and if there is data input, the data can be identified in the memory. Store.

As an event, if the cursor key is pressed, the cursor is moved, and if the end key is pressed,
Close the screen and exit. As described above, when the logical screen is larger than the actual screen, the entire logical screen is displayed in a reduced size, the window frame is displayed in a reduced size on the screen, and the desired item is displayed by moving the window frame. You can

Since the entire logical screen is displayed in this way, the operator can quickly grasp and specify the position of the desired item on the logical screen, and thus the display speed of the screen including the desired item can be increased. It becomes possible to do.

In the second embodiment, it is not necessary to display the entire screen if the entire logical screen cannot be read if it is displayed in a reduced size in the window. In this case, it is combined with scrolling such as screen-based scrolling.

Although the reduction processing is described at the time of displaying, reduced screen data may be created in advance and displayed.

[0057]

As described above, according to the present invention,
Since the scroll amount can be specified and whether the specified scroll amount has priority or the minimum scroll that displays the cursor in the next input area has priority, the scroll amount can be specified to shorten the scroll time. It has the effect of being able to deal with any screen.
