Abstract

PURPOSE:To change the size or position of a window by a simple operation by displaying the frames of the window by thick lines or double lines, and after inputting a window changing command, picking up the prescribed frame of the window to move the window. CONSTITUTION:The frames FR1-FR4 of the window WD displayed on the screen of a display CRT are displayed by thick lines or double lines so as to be easily picked up. After inputting a WINDOW OPEN command from a keyboard 17 or a tablet device 18, data for specifying the size and position of the window are inputted. A display processor 10 enlarges/reduces the size of the window WD in an optional direction, right, left, up, or down direction, by picking up the prescribed frame of the window WD and moving the window WD and moves the window WD based on an instruction from a mouse 18b included in the tablet device 18.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention <Industrial Application> The present invention relates to a window changing method, and particularly a window changing method 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 a display screen (CRT screen). 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.

By the way, in the past, it was not possible to change the position or size of a window once it was set, and the only function was to simply close the window. Therefore, when it is desired to change the size or position of a window, the window is closed, and then a window of the desired size is opened at the desired position.

<Problems to be Solved by the Invention> However, with this conventional method, there is a problem in that changing the window size and position is troublesome.

From the above, it is an object of the present invention to provide a window changing method that allows changing the size and position of a window with simple operations.

Means to solve problems〉 FIG. 1 is a schematic explanatory diagram of the method of the present invention.

CRT is a display screen, and WD is a window.

The window WD is rectangular and has four frames F R1 to F.
R4, each of which is displayed with a thick line so that it can be easily picked with a cursor.

Function> Each frame (FRI to FR4) of the window (WD) is displayed as a thick line or a double line so that it can be picked (see FIG. 1(A)).

Then, after inputting the window change command, pick and move the specified frame of the window (frame FR
In the case of I, FR3, move it up or down and frame FR
2. In the case of FR4, move it to the left or right)
, the size of the window (WD) is expanded/reduced in any direction left, right, top, or bottom (see FIGS. 1B to 1E).

Furthermore, by specifying and moving the point (P,) within the window frame, the entire window is moved and its position is changed (see FIG. 1(F)).

<Example> FIG. 2 is a block diagram of a device implementing the 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 stores image data separately, and 15 a window management table (window manager) that stores position data of each window and display priority data indicating which window should be displayed with priority when windows overlap. , 16 Display device (CRT) , 17
18 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 19te, and image data and various commands can be input from the keyboard 17, tablet device 18, and other data input/output devices (not shown).

Hereinafter, a window changing method according to the present invention will be explained with reference to FIGS. 1 and 2. Note that the frames FRI to FR4 of the window WD displayed on the display screen CRT are displayed with thick or double lines so that they can be easily picked (
(See Figure 1(A) and Figure 2).

(1) Enter the window open command on the keyboard 17
Alternatively, input from the tablet device 18.

(2) After inputting data for specifying the size and position of the window. If a window is to be specified by its two diagonal points, the two points PL, P3 (
P2. P4 may be used) as the two diagonal points of the window WD.

(3) As a result, the display processor 10 selects the remaining two diagonal points P2. P4 (Pt.

P3), and store the coordinate values of all corner points P1 to P4 in the window management table 15.

(4) If the window position is specified by the above operations, the window WD is drawn on the display screen CRT using a predetermined line type (see FIG. 1(A)).

(5) After the window image data is inputted from the database, keyboard 17, or other data input/output device (not shown), the display processor 10 transfers these image data to the window buffer memory 1.
4 in a predetermined storage area.

Thereafter, each window image stored in the window buffer memory 14 is written to the image buffer memory 13 with reference to the window position data stored in the window management table 15, and drawn on the CRT 16.

(6) By the way, if you want to change the size or position of the window WD after setting it, input a window change command from the keyboard or tablet device.

(7) If you want to change the size of the window WD after the window WD has been opened, pick a predetermined frame of the window and move it (in the case of frames FRI and FR3, move it up or down, and then move the frame FR2 , in the case of FR4, move it to the left or right).

(8) After the frame movement operation, the display processor 10 calculates the four corner points of the window again, updates the contents of the window management table 15, changes the size of the window, and displays it on the CRT. Figure 1 (A) is the window before the change, and Figure 1 (CB) and (C) are the respective frames FR.
This is an example of enlarging and reducing the window by moving frame FR1 to the left and right, respectively, and (D) and (E) in the same figure enlarge and reduce the window by moving frame FR1 upward and downward, respectively. This is an example.

(9) On the other hand, if the window position is to be changed, after inputting a window change command, the point P within the frame of the window WD (FIG. 1(A)) is picked and moved.

(I[6 display processor 1 after window movement
0 calculates the four corner points of the window again, updates the contents of the window management table 15, changes the position of the window, and displays it on the CRT.

FIG. 1 CF) shows the window after the position has been changed.

<Effects of the Invention> According to the present invention, the frame of the window is displayed as a thick line or double line so that it can be picked, and the size of the window can be changed by picking and moving a predetermined frame of the window after inputting a window change command. It is easy to operate because it is configured to expand/reduce the window in any direction left, right, top, or bottom, and to move the entire window and change its position by specifying and moving a point within the window frame. You can change the size and position of the window with
