2. Description of the Related Art Conventionally, as a scroll control of a display area of a document or the like in a window, a scroll instruction area for scrolling a scroll bar or the like is dragged and moved with a mouse or the like, or displayed in a corresponding scroll instruction area. A method of instructing scrolling by clicking a button or the like with a mouse or the like is well known.

In recent years, a so-called smooth scroll control system in which a display screen is scrolled one by one in accordance with the movement of a mouse has become popular.

To perform such a smooth scroll, the user drags and moves the slider portion of the scroll bar with the mouse while checking the contents of the display area, and temporarily stops the mouse when a portion desired by the operator appears. The conventional method is to complete the scroll processing.

[0006]

However, in the above-described conventional method, since the physical movement amount of the mouse and the scroll amount of the screen are not constant depending on the size of the document, various sentences are displayed one after another. In such a case or when the size of the window is changed, there is a disadvantage that it takes time to get used to the scroll amount.

In addition, especially when a long text is displayed, the document is greatly scrolled by a small amount of movement of the mouse, so that the delicate movement of the hand must always use nerves. , Which can be very difficult to use.

Further, with the recent increase in the speed of the CPU, there is a problem that even if the sentence is not a long sentence, the sentence is immediately scrolled by a slight movement of the mouse.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present embodiment described here
A means for the operator to freely set and change the moving distance amount of the scroll instruction device such as a mouse for scrolling the unit scroll amount of the display area to be scrolled with respect to the processing device for displaying the text, There is provided a means for measuring the moving distance of the pointer designated by the corresponding scroll instruction device one by one based on the set data, and for smoothly scrolling the window.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the overall configuration of this embodiment. In the figure, reference numeral 11 denotes various arithmetic processing (FIG. 4)
CPU for performing the scroll control shown in FIG.
Reference numeral 2 denotes a memory (RAM) for loading an OS or a program for processing by the CPU, 13 a display device for displaying a document or a window related to the document, and 14 an HDD (hard disk device) for storing a program or a file.
Is a mouse having at least two or more buttons for instructing scrolling of a window or the like displayed on the display device 13, and 16 is a keyboard. These 11 to 16 are connected to each other via a bus.

FIG. 2 shows a screen on which an operator sets a desired scroll amount in advance. In the figure, reference numeral 21 denotes an area for specifying a reference amount for scrolling, and reference numeral 22 denotes an area for specifying the unit. Reference numeral 23 denotes a mouse movement amount for scrolling by the amount specified in the above 21 and 22, which is specified in each of the vertical direction and the horizontal direction. Considering the case where it is not known how much the mouse movement corresponds to one pixel, select either 23 above or below and move the mouse into the 24 area, and then move the mouse there. When the mouse is moved while pressing the left button of, the pixel value corresponding to the amount of movement is automatically displayed in the corresponding area of 23. This makes it possible to intuitively specify a method such as “I want you to scroll one line when you move the mouse this much”.

In the example of FIG. 2, it is shown that the amount of the mouse pointer required for scrolling the display area by one line in the vertical direction is 10 pixels, and similarly, the amount in the horizontal direction is 20 pixels. I have.

These pieces of information are processed by a program loaded in the RAM 12 shown in FIG.
Is stored as a "scroll control information" file.

FIG. 3 shows the format of the "scroll control information" file. The moving amount of the mouse per one line or one pixel scroll designated on the screen of FIG. 2 is held as a value in each of the vertical direction and the horizontal direction.

FIG. 4 is a flow chart showing the flow of the vertical scroll processing in the present embodiment.
This flowchart is loaded into the RAM (12 in FIG. 1) in the form of a program and executed by the CPU 11.

The program loaded into the RAM 12 is
Through the operating system, the occurrence of an event such as movement or click of a scroll instruction device such as the mouse 15 is constantly monitored.

In the present program, it is determined whether or not the slider portion of the scroll bar of the window displayed on the display device 13 has been clicked with a mouse button. The determination is made in step 41.

For example, when the left button of the mouse is pressed, the conventional scroll processing mode is executed. Pressing the right button and grabbing the slider enters the scroll control mode described below.

In step 42, the position of the mouse cursor at the start of scrolling is stored in the mouse movement start position.

Next, the following scroll processing is executed while picking up mouse pointer movement events one by one.

In step 43, it is determined whether or not the mouse has moved. If the mouse has moved, in step 44, the vertical mouse movement distance is calculated from the mouse movement start position and the coordinates of the latest mouse pointer. I do.

If there is no movement of the mouse, a process of determining scroll end (step 49) is performed.

The mouse movement distance calculated in step 44 is compared with the contents of the scroll control information file stored in the HDD 14 (see FIG. 1) in the processing of FIG.
It is checked whether or not the mouse has moved a sufficient distance to scroll the line (or one pixel) (step 45).

If the mouse has moved a sufficient distance to scroll one line (or one pixel),
In step 46, a screen corresponding to the moving distance of the mouse pointer (only in the vertical direction) is shifted upward or downward and displayed on the window.

That is, using the example of FIG. 3, when the mouse is moved downward by 10 pixels while holding down the right button, the displayed document is moved downward by one line (the displayed document is shifted upward). It will be scrolled.

If scroll display cannot be performed any more at the beginning or end of the display text, the screen display processing is not performed.

In step 47, the current position of the mouse pointer is reset to the mouse movement start position.
Subsequently, in step 48, the position of the slider portion with respect to the entire display text is calculated, and the slider portion is moved to the corresponding position.

In the process of step 45, one line (or one line)
If the mouse has not moved a sufficient distance for scroll display of (pixels), the process jumps to the process of step 49 without performing any process such as display.

In step 49, when the mouse button is released, it is regarded that scroll processing has ended at that point, and the process exits a series of scroll processing flows.

If it is not determined that scrolling has ended, step 43 is performed in order to perform a mouse pointer movement determination process again.

FIG. 5 shows a specific screen movement when scrolling is performed in this embodiment.

When the mouse pointer 52 is moved using the right button of the mouse, and the mouse button is released at the position, the slider 51 is gradually moved from the position with the movement of the mouse pointer. When the mouse is temporarily released at the position, the position 51 is at the position.

Further, with this operation, the displayed document 53 also gradually moves in the direction from and finally reaches the original position.

If you want to scroll down further,
This can be done by dragging the slider at the position of.

If the mouse pointer is moved again without releasing the slider, the document returns to the initial position in accordance with the movement.

The normal scrolling can be performed by using the left mouse button.

In the present embodiment, scroll start and end processes are determined by grasping and releasing the slider in the scroll instruction area of the screen with the mouse. It is also possible to use a portion, a double click of a mouse button, or the like to determine scroll start or end processing.

When a long document is read while being smoothly scrolled, considering scrolling downward at the end of the document and scrolling upward at the beginning of the document, the window may be read. Even if you drag the scroll bar outside the scroll instruction area or window, you can create a judgment process so that the scroll process of the window can be continued until the end of the scroll process is instructed. It is possible.

Further, in the above case, for example, in the case of scrolling only in the vertical direction, the scroll amount is determined not only by the moving distance of the mouse in the vertical direction but also by the moving distance of the simple mouse pointer taking into account the moving distance in the horizontal direction. It is also possible to calculate.

As the scroll amount setting information, the mouse movement amount necessary for scrolling one line of a sentence is included. However, in the case of a draw-type document other than a document or an image display, a pixel value is used. It is also possible to set by using.

On the contrary, it is also possible to manage the information as the information of the document scroll amount per unit moving distance of the mouse.

[0064]

As described above, according to the present invention, by setting an arbitrary value in advance by an operator, the scroll amount of the screen can be freely changed with respect to the physical movement amount of the mouse or the like. A scroll control device and method that can be determined can be realized.

According to the present invention, even when a document or the like of any size is displayed, the same amount of mouse movement (or the amount of movement of another scroll instruction device) is used to scroll the document by the same amount of scrolling. A scroll control device and method that can be realized can be realized.

More specifically, the following special effects can be obtained.

(A) Regardless of the size of the document being displayed, a constant scroll amount can be obtained with respect to the movement amount of the scroll instruction device such as a mouse, so that the sense of scroll is kept constant. When scrolling a long sentence, the user is not distracted by the subtle movement of the mouse operation.

(B) By being able to set an arbitrary scroll amount of the user, it is possible to realize scrolling that suits the user's preference.

(C) Scroll processing according to the present invention;
The user can easily select the conventional scroll processing, and the user can immediately switch to the conventional scroll processing depending on the type of the displayed document and how to read the document.
