Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a document editing editor, and more particularly to a method for controlling the mutual positional relationship between a window and a cursor in a full-screen editor.

[Background of the invention]

In a conventional full-screen editor that has a window and a cursor, there is no special positional relationship between the window and the cursor, and when the operator specifies the window position, a screen scroll command or a cursor position is used. When specifying, it was done independently using cursor movement keys. In this way, traditional editors
The operator has to specify the window and cursor positions independently, which causes deterioration in operability.

[Purpose of the invention]

An object of the present invention is to provide the most natural positional relationship between a window and a cursor from the operator's perspective in a full-screen editor, and to enable the operator to more easily control the positions of the window and cursor.

[Summary of the invention]

The key point of the present invention is that the positional relationship between the window and the cursor in a full-screen editor is understood as a wooden frame and a ball rolling within it, and the mutual positions of the window and cursor are controlled according to that relationship.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described in detail using the drawings.

FIG. 3 shows the relationship between the window, cursor, and text being edited in this embodiment. Window 1 cannot display the text 2 being edited at once on display device 3 because it is large.
This is a viewing window for selecting and displaying a portion of it. Further, a cursor 4 is a pointer for specifying an editing location in the text.

FIG. 4 shows the positional relationship between the wooden frame, which is the basis of the present invention, and the balls rolling therein. When the wooden frame 5 is moved, the ball 6 does not move until it collides with the wooden frame 5, but after colliding with the wooden frame 5, the ball 6 is dragged by the wooden frame 5 and moves. Conversely, when the ball 6 is moved, the wooden frame 5 does not move until it collides with the ball, but after the collision, it is dragged by the ball 6 and moves.

FIG. 5 shows the relationship between a window and a cursor in the present invention. The wooden frame in Figure 4 corresponds to the window, and the ball corresponds to the cursor. Figure 5a shows that when window 7 is moved,
The cursor 8 does not move until it collides with the window 7, but after the collision, the cursor 8 is dragged by the window 7 and moves. FIG. 5b shows that when the cursor 9 is moved, the window 10 does not move until the cursor 9 collides with it, but after the collision, the window 10 is dragged by the cursor 9 and moves.

FIG. 1 shows the configuration of a full screen editor embodying the present invention. In the figure, 11 is a central processing unit that stores and executes programs and data, and logically includes a command analysis device 13,
Command execution device 14, text editing area 16
and a screen display control device 17. A window and cursor position control device 15, which is a major part of the present invention, is included in the command execution device 14. The input/output devices of the central processing unit 11 include a keyboard 12 for inputting commands, a hard disk for storing text files, an external storage device 18 such as a floppy disk, and a keyboard for displaying the contents of the text being edited. A display 19 is connected. In this example, a scroll command to move the window position,
All inputs such as arrow keys for moving the cursor are processed in the order of keyboard 12→command analysis device 13→command execution device 14→window and cursor position control device 15→screen display control device 17→display 19.

FIG. 2 shows the processing flow of the window and cursor position control device 15, which is the central feature of the present invention. When a command input from the keyboard 12 is a command to move a window and a cursor, the window and cursor position control device 15 is activated, and first, it is determined whether the command is to move the window or the cursor. In the case of cursor movement, after positioning the cursor at the specified position, the window position is moved to the second position according to the relationship between the wooden frame and the ball explained in Figure 4.
Adjustments are made according to the flow shown in Figure a. In the case of window movement, after the window is positioned at a designated position, the position of the cursor is similarly adjusted according to the relationship between the wooden frame and the ball according to the flow shown in FIG. 2b.

〔Effect of the invention〕

According to the present invention, the position of the window and cursor in a full-screen editor can be specified by focusing only on either the window or the cursor, so that the operator can more easily control the position of the window and cursor. This has the effect of greatly improving the operability of the full screen editor.

Claims (1)

[Claims] 1 In an editor that has a viewing window (called a window) for selecting a part of text and displaying it on a display device, and a pointer (hereinafter called a cursor) for specifying the editing location in the text, move the window or cursor. , a window cursor position characterized in that the cursor or window remains as it is until the window or cursor hits the cursor or window, and after it hits the cursor or window, the cursor or window is positioned at the movement position of the window or cursor. control method.
