Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window control device for controlling a cursor in a window system.

[0002]

2. Description of the Related Art Many computers currently being developed (personal computers, workstations, etc.)
Has a window system. This window system displays a plurality of virtual screens (hereinafter referred to as windows) on the screen, and each window can display a large amount of information independently of other windows at the same time.

As a result, a user can run completely different applications for one data, see from various viewpoints, read various data into one application, and combine the results into one data. Become.

Further, in order to handle such a window system, each computer provides its own user interface. The user interface is roughly divided into two. One is CUI (Character User Interface), and the other is GUI (Graphical User Interface Grap).
hical User Interface). The CUI mainly has a keyboard as an input device, and basically inputs commands from the keyboard or selects commands using function keys. However, at present, there are many inconveniences such as having to remember which command each key corresponds to only by key operation. Therefore, the GUI is currently the mainstream. The GUI mainly has a pointing device represented by a mouse as an input device. The mouse controls a mark indicating a position on the screen (hereinafter referred to as a cursor) to give the user a means for visually indicating the position.

Since the mouse can freely move the cursor on the screen, it is possible to move between windows displayed on the screen, resize windows, switch windows, or select commands. Unlike the operation of the cursor keys and function keys, the operation with the mouse moves the data by operating the symbol that is right next to the data to be operated on the screen, and has the characteristic that it is easy to understand intuitively. Therefore, the operation using the mouse instead of the keyboard in the CUI is the basis of the window system. Also, an application running on a window system is generally based on mouse operation for the purpose of unifying the operability with the window system.

As a conventional example, an operation example of a window system using a mouse as an input device will be shown below. FIG. 6 is a block diagram of a conventional data processing device. Generally, in a data processing device, a central processing unit 1 that processes input information and a display device 2 that displays windows, graphics, characters, etc.
A mouse 3 used to select arbitrary position information or a displayed menu and having a decision button 31 for determining the position information or the selected menu, and a keyboard 4 for inputting characters, numerical values, etc. And a fixed storage device 5 for storing an OS, a program, and the like, and a temporary storage device 6 for storing data used by the program.

FIG. 7 shows the relationship between the mouse 3 and the cursor 32 under such a configuration. The mouse 3 is moved back and forth and left and right on the table, and the amount of movement at that time is input to the central processing unit 1 as a signal in the X and Y directions. In the central processing unit 1, the coordinates are calculated from the current position of the cursor 32 based on the movement amount and the cursor 32 is moved to that position. The user points the desired position with the cursor 32 and reflects the user's intention on the computer.

[0008]

However, in such an environment mainly composed of the mouse 3, in the conventional window system, the movement of the cursor 32 accompanying the mouse operation is limited to the display screen 21, and the window is displayed. In the worst case, it is necessary to move the cursor 32 from one end to the other end of the display screen 21 in order to perform a certain operation if a large number of them are created or spread out in 21. It will be a big obstacle.

The present invention solves the above problems, and an object of the present invention is to provide a window control device which requires less mouse movement for cursor movement and can perform efficient work.

[0010]

According to the present invention, in order to achieve the above object, when a mouse is operated so that the cursor moves outside the edge of the display screen, the window system displays the cursor on the left (right) side of the display screen. ) Change the coordinates of the cursor to control the movement of the cursor so that it goes out from the edge and comes in from the right (left) edge, or goes out from the upper (lower) edge and comes in from the lower (upper) edge. It is provided with a computing means for performing.

[0011]

According to the present invention, when the time dependent on the mouse operation is inevitably long like a window system premised on the use of a mouse, the above-described configuration allows the display screen to be enlarged from end to end. Acts to reduce the operation of moving the cursor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration of a data processing device according to the present invention. A central processing unit 1 for processing information input in FIG. 1, a display unit 2 for displaying windows, graphics, characters, etc., and position information used for selecting arbitrary position information and displayed menus. A mouse 3 having a decision button 31 for deciding a selected menu, a keyboard 4 for inputting characters, numerical values, etc., a fixed memory for storing an OS, a window system, and a program according to the flowchart shown in FIG. It is composed of a device 5 and a temporary storage device 6 for temporarily storing data used in a program according to the flowchart shown in FIG.

The relationship and operation of each constituent element in the window system used in the above-described constituent data processing apparatus will be described.

First, as described in the conventional example, the cursor 32 is moved by the mouse 3 by moving the mouse 3 forward, backward, leftward and rightward on the table, and the movement amount of the mouse 3 at that time is X, Y.
It is input to the central processing unit 1 as a direction signal. Then, the coordinates are calculated from the current position of the cursor 32 based on the amount of movement, and the cursor 32 is moved to that position. As shown in FIG. 2, the range of screens that can be controlled by the window system is predetermined (the size of the screen that can be normally displayed on the display device), and the minimum and maximum values of this size are set separately in the X and Y directions ( Xmin, Xmax), (Ymin, Yma
x) is stored in the temporary storage device 6.

Next, how to control the movement of the cursor on the basis of this size will be explained by means of the present invention. The flow chart of FIG. 3 is used to explain this means. Further, for convenience of explanation, FIG. 4 is also used.

First, the size of the display screen Xmin, Xmax, Y
min and Ymax are taken out from the temporary storage device 6. Next, when the mouse 3 is moved, the position where the cursor 32 moves next is calculated from the moving amount of the mouse 3 at that time. The calculated value is (X, Y) (FIG. 3 flow B). Here, X is Xmin> X (FIG. 4 (c)) or X> Xmax (FIG. 4).
(A)) or Y is Ymin> Y (FIG. 4 (d)) or Y> Ymax (FIG. 4 (b)) is separately processed.

(1) Either X or Y is Xmax,
When it becomes larger than Ymax, the values of X and Y are changed as follows. That is, when X> Xmax, the value of X is set to Xm.
Change to in + (X-Xmax) (Flow C in FIG. 3), Y> Ymax
In the case of, the value of Y is changed to Ymin + (Y−Ymax) (Flow D in FIG. 3).

(2) Either X or Y is Xmin,
When it becomes smaller than Ymin, the values of X and Y are changed as follows. That is, when X <Xmin, the value of X is changed to Xmax− (Xmin−X) (Flow E in FIG. 3), and Y <Y.
In the case of min, the value of Y is changed to Ymax- (Ymin-Y) (Flow F in FIG. 3).

Thereafter, the cursor 32 is moved based on the calculated (X, Y) (Flow G in FIG. 3).

FIG. 5 shows a case where the cursor 32 is controlled by using the above means. When the cursor 32 exits the right (left) end boundary line, the cursor appears from the left (right) end boundary line, and when it exits the upper (lower) end boundary line, the lower (upper) end boundary line appears. .

As described above, according to this embodiment, the central processing unit calculates the cursor coordinates according to the information of the temporary storage unit and the mouse according to the program stored in the fixed storage unit, so that the amount of work for moving the cursor is reduced. To do.

[0022]

As is apparent from the above description, according to the present invention, since the movement of the cursor in the window system is controlled by calculation, the position closer to the end of the screen is closer to the end in the opposite direction. When the cursor is moved to the position, it is possible to provide a window control device that is effective in improving work efficiency, such as less movement of the mouse and reduction of operations that have been frequently performed until now.
