JPS6175429A - Control system for window cursor position of editor - Google Patents

Abstract

PURPOSE:To allow an operator to easily perform position control by controlling the position relation between a window and a cursor under the control of a full-screen editor according to the relation between a wooden frame and a ball which rolls therein. CONSTITUTION:When a command inputted onto a keyboard 12 is a command for moving the window and cursor, a position controller 15 for the window and cursor is actuated and it is judged firstly whether the command is for window movement or cursor movement. When the command is a command for cursor movement, the cursor is set at a specific position and then when the relation between the wooden frame and ball is varied, i.e. when the cursor is moved, the window is fixed until the cursor collides with the window, but the window is moved together with the cursor after the collision. When the command is for window movement, the window is set at a specific position and then the cursor does not moves until the window collides with it when the relation between the wooden frame and ball is varied, i.e. when the window is moved, but the window is moved after the collision.

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.6 [Background of the Invention] Conventional window In a full-screen editor that has a cursor and a cursor, there is no special positional relationship between the window and the cursor, and when the operator specifies the window position, the operator uses a screen scroll command and specifies the cursor position. In some cases, this was done independently using cursor movement keys. In this way, in a traditional editor.

The operator had to specify the window and cursor positions independently, leading to poor operability.

[Purpose of the invention]

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

[Summary of the invention]

The key point of the present invention is that the positional relationship between a window and a 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 relationship6. Embodiment] An embodiment of the present invention will be described in detail below using one drawing.

FIG. 3 shows the relationship between the window, cursor, and text being edited in this embodiment. This is because the text 2 being edited in window 1 is too large to be displayed on the display device 3 at once.

This is a viewing window for selecting and displaying a portion of it. Further, the cursor 4 is a pointer for specifying the edit 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. If you move the wooden frame 5,
The ball 6 does not move until it collides with the wooden frame 5, but after the collision, it 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 the window and the cursor in the present invention. The wooden frame in Figure 4 corresponds to the window, and the ball corresponds to the cursor.
A) shows that when the window 7 is moved, the cursor 8 does not move until it collides with the cursor 7, but after it collides with the window 7, the cursor 8 is dragged by the window 7 and moves. FIG. 5(b) shows that when the cursor 9 is moved, the window 10 does not move until the cursor 9 collides with the window 10, 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, a command execution device 14. It is composed of a text editing area 16 and a screen display control device 17. A window and cursor position control device 15, which forms the main 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, and an external storage device 18 such as a floppy disk. and a display 19 for displaying the contents of the text being edited. In this embodiment, a scroll command is used to move the window position.

All inputs such as arrow keys for moving the cursor - keyboard 12 -> command parsing device 13 -> command execution device 14 -> window and cursor position control device 15 ->
Processing is performed in the order of screen display control device 17→display 19.

FIG. 2 shows the processing flow of the window and cursor position control bag @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 changed to Ca in Figure 2 according to the relationship between the wooden frame and the ball explained in Figure 4.
) is adjusted by the flow. In addition, in the case of window movement, after positioning the window at the specified position, the cursor position similarly follows the relationship between the wooden frame and the ball as shown in Figure 2 (
It is adjusted based on the flow of b).

〔Effect of the invention〕

According to the present invention, the positions of windows and cursors 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 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, the window or cursor , the cursor or window remains as it is until the cursor or cursor hits the cursor or window, and after the cursor or cursor hits the cursor or window, the cursor or window is positioned at the moved position of the window or cursor.
