JPS62276671A - Setting method for window - Google Patents

Abstract

PURPOSE:To easily set up a window with prescribed size by setting up the window on a display screen so that a point specified by window opening operation is positioned on the previously fixed point of the window. CONSTITUTION:The size of the window to be set up on the display screen is previously specified and stored in a RAM 11. A WINDOW OPEN command is inputted from a keyboard 17 or a tablet device 18. One point on the screen is designated by a mouse 18b included in the tablet device 18. A display processor 10 sets up the window on the screen of a CRT 16 so that the designated point is positioned on the center of a square or a prescribed point of the four corners of the square.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a window setting method, and is particularly suitable for application to a display device having a multi-window image display function. Regarding.

<Prior Art> There are cases where it is desired to display one or more window images on the display screen (CR7 screen). Conventionally, in such multi-window image display, the size and position of the window are specified by specifying two diagonal points of the window, and a predetermined window image is displayed on the window.

<Problems to be solved by the invention> However, in the conventional window setting method, it is necessary to pick two diagonal points in consideration of the size and position of the window to be set, which makes the window setting operation troublesome. was there.

From the above, the purpose of the present invention is to simplify the operation. In other words, it is possible to set a window of a predetermined size on the display screen by simply picking one point without considering the window size. The purpose is to provide a window setting method.

Means for Solving the Problems> FIG. 1 is a block diagram of a display device that implements the method of the present invention.

10 is a display processor, 11 is a RAM.

12 is a control program memory (ROM), 13 is an image buffer memory, 14 is a window puffer memory, 15 is a window management table (widow 7 manager), 16 is a display device (CRT), 17 is a keyboard, 18 is a cube notebook device, 18a is the Kubrenot body, and 18b is the mouse.

Function> Window (WD) set on the display screen in advance
The size of Pu
with the mouse 18b provided on the tablet device 18, and move the display screen (
Setting a Window (WD) on a CRT (Embodiment) FIG. 1 is a block diagram of an apparatus that implements the present invention.

10 is a display processor that controls image display and window management according to a predetermined control program;
11 is a RAM 112 that stores processing results, etc., is a control program memory; 13 is an image buffer memory that has a storage area corresponding to each pixel (picture element) on the screen; and 14 is a memory for displaying window images A and B displayed in each window. A window buffer memory that separately stores image data; 15 a window management table (window manager) that stores position data for each window and display priority data that indicates which window should be displayed with priority when windows overlap; , 16 display @ (CRT),
17 is a keyboard, 18 is a tablet device, 18a is a tablet body to which a menu table is attached, and 18b is a mouse.

The devices 10 to 18 are interconnected via a bus line 19, and image data and various commands can be input from a keyboard 17, a tablet device 18, and other data input/output devices (not shown).

Now, in multi-window image display, (1) cases where accurate position and size of each window are required, and (2) cases where keyboard input data is displayed, etc.
There are two cases in which it is sufficient that a window of a predetermined size exists in a position where it does not interfere with the display of other images. And the latter is used much more often than the former.

Therefore, in the present invention, in the former case, the window can be set by specifying two points on the display screen as in the past, and in the latter case, the window can be set by specifying one point. In the latter case, window setting operations are simplified.

The window setting method according to the present invention will be explained below. Note that the sizes X, Y, of the window WD to be set on the display screen are specified and stored in the RAM 11 in advance.

(1) Enter the window open command on the keyboard 1'
7 or input from the tablet computer 1-device 18.

(2) The display processor 10 recognizes that the command is
It is determined whether the window open command sets a window by picking a point or the window open command sets a window by picking a single point.

(If the window open command is based on a 312-point pick, the display processor 10 then uses the two points on the CRT picked with the mouse 18b with the ra circle on the tablet l-'7i18 as the two diagonal points of the window. The remaining two diagonal points are calculated, and the coordinate values of all these corner points are stored in the window management table 15.

(4) On the other hand, if the input command is a window open command by picking a single point, the display processor 10 thereafter selects the one point PL, l on the CRT picked with the mouse 18b provided in the tablet device 18 as a window open command. It is regarded as the center or one of the four corner points. It is assumed that whether the picked point I-P is the center or which corner point among the four corner points is set in advance and stored in RAMII.

Next, the dip processor 10 uses the X, Yl stored in the RAM 11 to
The coordinate values of the corner points are calculated and stored in the window management table 15.

(5) After the window position is specified through the above operations, if window image data A and B are input from the database, keyboard 17, or other data input/output device (not shown), display process 1. 12 is stored in a predetermined storage area of the window buffer memory 14.

Thereafter, each window image stored in the window buffer memory 14 is stored in the window management table 1.
The window position data stored in 5 is written to the image buffer memory 13 and drawn on the CRT 16.

In addition, in the method of setting the window by picking one point,
In some cases, a window of the set size cannot be set. In such a case, an error message is displayed, or a window of a possible size is set while maintaining the ratio of X, . . . :y.

<Effects of the Invention> According to the present invention, the size of the window to be set on the display screen is specified in advance, and one point on the display screen is specified in the window opening operation.
Since the window is configured to be set on the display screen so that the specified point becomes a predetermined point on the window, it is possible to easily create a window of a predetermined size without considering the window size. Can be set on the display screen.
